# KinToolkit

> Educational dosage calculators for common children's medicines. KinToolkit is not medical advice and is not affiliated with the medicine brands named on the site.

## When to use KinToolkit

- Find a supported children’s or infant medicine calculator and its manufacturer source: read the [public catalog](https://kintoolkit.com/api/catalog.json).
- Look up a printed US bottle-label row: connect to the public MCP endpoint, call `list_calculator_bottles`, then `get_label_directions` with the exact published product, concentration and label-band identifiers.
- Cite a reference or retrieve accessible text: use the canonical URL and Markdown link returned in the catalog.

Keep the complete directions, limitations and source together. Do not use KinToolkit to diagnose, prescribe, calculate a personalized dose, convert concentrations, or process patient details. No account, API key, OAuth grant or agent registration is required. See the [KinToolkit developer guide](https://kintoolkit.com/developers) for connection examples and limits.

Official CLI (Node.js 24+): install the [versioned KinToolkit package](https://kintoolkit.com/downloads/kintoolkit-1.0.0.tgz) with `npm install --global https://kintoolkit.com/downloads/kintoolkit-1.0.0.tgz`, then run `kintoolkit bottles`. See the [developer guide](https://kintoolkit.com/developers) for label lookup commands. This is a direct website download; npm registry publication is pending.

Each Markdown document corresponds to its canonical HTML page. Both formats use the same calculator data. Cite the canonical page and retain the bottle concentration, age restrictions, interval and maximum together; the manufacturer label remains the primary source. KinToolkit does not claim clinical certification.

Bottle-specific reference pages cover only the printed weight or age bands already available in the calculator. Every reference retains the exact liquid strength, label amount or ask-a-doctor boundary, interval, maximum and source. They are public label references, not personalized prescriptions. Selector states and duplicate age alternatives are excluded from the sitemap and discovery catalog.

Supported browsers may expose the read-only WebMCP tool `get_kintoolkit_catalog`. It lists public resources and never reads a child's form inputs or calculates a dose.

## Remote label-reference tools

### Supported reference workflow

Use KinToolkit to discover supported US liquid medicine bottles, retrieve one published label row, or cite its public reference URL. Do not use it to decide whether a medicine or amount is suitable for an individual child.

Connect an MCP client to `https://kintoolkit.com/api/mcp` using Streamable HTTP. The endpoint is public and stateless; it does not require an account or authentication.

- `list_calculator_bottles({})` lists the five supported US liquid bottles, their exact concentration strings, and the public `label_band` IDs available for each bottle.
- `get_label_directions({product_id, concentration, label_band})` returns the corresponding published label reference. Use values from the bottle list, such as `{"product_id":"motrin-infant","concentration":"50 mg / 1.25 mL","label_band":"12-17-lb"}`. A mismatched concentration, unsupported combination, or extra argument is rejected.

Results retain the bottle strength, paired label weight and age where applicable, label amount or `ask_doctor` with a null amount, full directions and limits, source, and canonical reference URL. Preserve these together when presenting an answer. Do not convert strengths, interpolate between bands, infer a personalized dose, or replace an `ask_doctor` result with an amount.

The tools accept public label identifiers only. Do not send names, exact patient ages or weights, medical history, or other personal details. KinToolkit does not send MCP arguments or returned directions to PostHog. The server and hosting provider process request bodies to answer calls; the MCP client's own privacy policy also applies. See the [Privacy Policy](https://kintoolkit.com/privacy).

The server sends limited MCP operational events to PostHog: protocol operation or supported tool name, technical outcome category, HTTP status, processing time, test marker, and a random per-request identifier. These events exclude request/response bodies, arguments, returned values, medicine, concentration, label band, caller IP address, user-agent and client information, headers, referrers, and query strings. They use no persistent client identifier; IP attribution and person profiles are disabled. Hosting and security systems may separately process network addresses and maintain counters to detect and limit excessive traffic. See the [developer guide](https://kintoolkit.com/developers) for details.

MCP abuse limits: one JSON-RPC message per HTTP request; batches are rejected. The hosting firewall permits up to 120 requests per IP per 60-second regional window. On HTTP 429, respect Retry-After if supplied; otherwise back off at least 60 seconds with jitter. Shared IPs share a limit.

# KinToolkit Developer Guide: MCP Label References

Canonical URL: https://kintoolkit.com/developers
Updated: September 24, 2026

Connect to the public KinToolkit MCP server, discover supported bottles and label bands, and preserve label directions, limits and sources.

## When to use KinToolkit

Use this service to discover supported US liquid medicine bottles, retrieve one published label row, or cite its public reference URL. The service covers five bottles and 20 canonical label rows. It does not determine whether a medicine or amount is suitable for a particular child.

Educational US liquid medicine label lookup, not a personalized prescription. Use only an exact listed bottle, concentration and published label band. Never send names, exact measurements, medical history or other patient details. Do not interpolate, convert concentrations or infer that a label reference is safe for a particular child. Preserve the age restrictions, directions, maximum and source together; verify the full package label and ask a clinician when unsure.



## Connect

MCP endpoint: https://kintoolkit.com/api/mcp. Transport: Streamable HTTP. This is a public, stateless service: no account, API key, OAuth grant or persistent session is required. Use a compatible MCP client to initialize, list tools and call tools.

The server supports MCP protocol negotiation, including 2025-11-25. The SDK handles protocol headers and message metadata. Calls use HTTP POST; a standalone GET or DELETE returns 405 because this service does not provide a persistent SSE subscription or session deletion.

Use a server or local client. Requests with an untrusted Origin are rejected; cross-origin browser access to the MCP endpoint is not enabled.



## Codex CLI

Run these commands in your terminal to register the remote server and inspect its configuration. No bearer token or MCP login is needed. Start a new Codex session after adding it.

```sh
codex mcp add kintoolkit --url https://kintoolkit.com/api/mcp
codex mcp get kintoolkit
```

- [Official Codex MCP guide](https://developers.openai.com/codex/mcp)

## Claude custom connector

In Claude, open Customize > Connectors, choose + then Add custom connector, and enter KinToolkit with the remote MCP URL https://kintoolkit.com/api/mcp. Leave OAuth client credentials empty. Add the connector, then enable it for the conversation through the + menu > Connectors.

For a Team or Enterprise organization, an owner first adds the endpoint in Organization settings > Connectors > Add > Custom > Web. Members can then connect and enable it. Claude remote connectors reach the endpoint from Anthropic infrastructure, so users may share the same network rate limit.

- [Official Claude custom-connector guide](https://support.claude.com/en/articles/11175166-get-started-with-custom-connectors-using-remote-mcp)

## Claude Code

Run these commands from the project where you want the server. Local scope keeps the connection private to you and limits it to that project; it does not make the remote server run locally. The get command checks the connection. In a Claude Code session, /mcp shows server status and tools.

```sh
claude mcp add --transport http --scope local kintoolkit https://kintoolkit.com/api/mcp
claude mcp get kintoolkit
```

- [Official Claude Code MCP guide](https://code.claude.com/docs/en/mcp)

## Cursor

Merge this entry into .cursor/mcp.json in your project. Use ~/.cursor/mcp.json instead if you want the connection available across your projects. Keep any existing mcpServers entries. Cursor supports the remote HTTP URL directly; no local bridge or authentication headers are needed. Review and enable the server and its tools in Cursor.

```json
{
  "mcpServers": {
    "kintoolkit": {
      "url": "https://kintoolkit.com/api/mcp"
    }
  }
}
```

- [Official Cursor MCP guide](https://cursor.com/docs/mcp)

## Verify your connection

Ask your client to use KinToolkit to list supported bottles and public label-band identifiers. It should expose list_calculator_bottles and get_label_directions. A successful connection is not a medical assessment; never provide a child’s personal details to these tools.

Client organization policies may control whether custom servers are available. These manual setup instructions do not imply a listing or endorsement in any client’s directory.



## KinToolkit CLI

The official KinToolkit CLI requires Node.js 24 or newer. Install the versioned package directly from this website, then list bottles or look up a public label row. It prints the complete structured result, including limitations and sources, and exits unsuccessfully on invalid inputs or service errors. It accepts public product, concentration and label-band identifiers only.

This direct download is available now. Publication to the npm registry is pending; do not use the bare npm package name until a registry release is announced. The CLI calls the same public MCP endpoint and shares its request limits. No login or API key is required.

```sh
npm install --global https://kintoolkit.com/downloads/kintoolkit-1.0.0.tgz
kintoolkit bottles
kintoolkit label --product-id motrin-infant --concentration "50 mg / 1.25 mL" --label-band 12-17-lb
```

- [Download KinToolkit CLI 1.0.0](https://kintoolkit.com/downloads/kintoolkit-1.0.0.tgz)

## Public API and OpenAPI

GET /api/catalog.json returns calculator and label-reference URLs, Markdown alternatives, sources and MCP connection information. POST /api/mcp accepts MCP JSON-RPC messages; use an MCP client for protocol setup and tool calls. Both endpoints are public: no registration, account, API key or OAuth is required.

The OpenAPI 3.1 document describes these existing HTTP operations with unique operation IDs, typed inputs and response schemas. MCP tool schemas come directly from the runtime definitions. For model function calling, use the MCP tools and preserve their complete results; the HTTP message operation is not a standalone dose function.

The catalog, CLI bottles command and Quickstart below are safe ways to try the service with public reference identifiers. There is no separate sandbox or account data to create.

```sh
curl -sS https://kintoolkit.com/api/catalog.json
curl -sS https://kintoolkit.com/openapi.json
```

- [KinToolkit OpenAPI specification](https://kintoolkit.com/openapi.json)

## Quickstart

In a Node.js 24 project, install @modelcontextprotocol/client@^2.1.0. Save this example as an .mjs file and run it with Node. It reads a predefined public label row; it does not accept child details.

```javascript
import { Client, StreamableHTTPClientTransport } from '@modelcontextprotocol/client';

const client = new Client({ name: 'label-reference-example', version: '1.0.0' });
try {
  await client.connect(new StreamableHTTPClientTransport(new URL('https://kintoolkit.com/api/mcp')));
  const { tools } = await client.listTools();
  const bottles = await client.callTool({ name: 'list_calculator_bottles', arguments: {} });
  if (bottles.isError) throw new Error('Bottle lookup failed.');
  // Public label identifiers from the bottle list, never patient details.
  const answer = await client.callTool({
    name: 'get_label_directions',
    arguments: { product_id: 'motrin-infant', concentration: '50 mg / 1.25 mL', label_band: '12-17-lb' },
  });
  if (answer.isError) throw new Error('Unsupported label reference. Check the bottle list.');
  console.log(answer.structuredContent); // Preserve the complete reference, including limitations and source.
} finally {
  await client.close();
}
```



## list_calculator_bottles

List the five supported US liquid medicine bottles, exact concentrations and public label-band identifiers. No patient inputs. Minimal operational telemetry records no tool arguments or results.

Call with an empty object. Each bottle includes its exact concentration, ingredient, source, and valid label_band identifiers with paired age/weight labels and public URLs.

```json
{
  "type": "object",
  "properties": {},
  "additionalProperties": false
}
```



## get_label_directions

Look up one public label row using identifiers from list_calculator_bottles. Requires an exact bottle/concentration match. Returns label amount or ask_doctor, age and weight restrictions, full directions, source and canonical URL. Does not determine suitability for a child. Minimal operational telemetry records no tool arguments or results.

Copy all three strings from the bottle list. The enum lists describe allowed values individually; the server also validates that the product, concentration and label band belong together. Extra arguments are rejected.

```json
{
  "type": "object",
  "additionalProperties": false,
  "required": [
    "product_id",
    "concentration",
    "label_band"
  ],
  "properties": {
    "product_id": {
      "type": "string",
      "enum": [
        "tylenol-child",
        "tylenol-infant",
        "motrin-child",
        "motrin-infant",
        "zyrtec-child"
      ]
    },
    "concentration": {
      "type": "string",
      "enum": [
        "160 mg / 5 mL",
        "100 mg / 5 mL",
        "50 mg / 1.25 mL",
        "1 mg / mL"
      ]
    },
    "label_band": {
      "type": "string",
      "enum": [
        "under-24-lb",
        "24-35-lb",
        "36-47-lb",
        "48-59-lb",
        "60-71-lb",
        "72-95-lb",
        "under-12-lb",
        "12-17-lb",
        "18-23-lb",
        "under-2-years",
        "2-5-years",
        "6-11-years"
      ]
    }
  }
}
```



## Read the complete result

Successful calls return structuredContent and a JSON copy in content[0].text. A directions result includes status, product_id, name, ingredient, concentration, label_band, weight_band, age_band, label_amount, directions, limitations, source, source_checked, source_check_note and url.

A label_reference result has a string label_amount. Preserve it as a string: some labels contain discrete alternatives. An ask_doctor result is also a successful lookup and has label_amount: null. Never turn that into zero, an estimated amount, or a personalized recommendation.

Keep the bottle concentration, paired label age and weight, directions, limits, source and canonical URL together. source_checked records source verification, not clinical review.



## Errors and limits

Check result.isError after every tools/call. Invalid arguments or unsupported combinations return a tool error; HTTP 200 alone does not indicate a successful tool call. A tool error has explanatory content and no structuredContent. Use list_calculator_bottles to correct a mismatch; do not substitute another strength or interpolate.

Send one JSON-RPC message per HTTP request; batches and malformed JSON return HTTP 400. Request bodies larger than 16,384 bytes return 413. The function has a ten-second execution limit. Untrusted Origin headers return 403. Unsupported GET and DELETE operations return 405. Application-controlled protocol rejections return JSON-RPC errors with error.code, error.message and error.data containing a reason, resolution hint and documentation URL. SDK protocol errors retain their standard JSON-RPC shape. Unknown API routes return JSON error details; request Accept: application/problem+json for the problem-details media type. Unknown page requests with Accept: text/markdown retain HTTP 404 and a Markdown recovery guide. Responses are not cached. The hosting firewall limits /api/mcp to 120 HTTP requests per IP per 60-second fixed window in each region, across methods and hostnames. Excess requests return HTTP 429 before reaching the application. Shared networks or MCP providers share the same IP limit. Counters are regional, not a single worldwide quota. On 429, follow Retry-After when supplied; otherwise back off for at least 60 seconds with jitter. Do not retry immediately.



## Privacy

Do not send names, exact patient ages or weights, symptoms, medical histories, free text or other personal details. The tools accept only the listed public label identifiers; they do not accept a caregiver confirmation flag.

KinToolkit does not log raw MCP request or response bodies in the application or send tool arguments or returned values to PostHog. The server and hosting provider process request bodies to answer calls; your MCP client also processes data under its own policy.

The server sends an mcp_request operational event to PostHog with only an allowlisted protocol operation or supported tool name, a technical outcome category, HTTP status, processing duration, is_test, and a random per-request event identifier. Outcome categories are success, tool_error, protocol_error, rejected, server_error, accepted, or unclassified. These records exclude medicine, concentration, label band, caller IP address, user-agent and client information, headers, referrers, and query strings. They use no persistent client identifier; IP attribution and person profiles are disabled. PostHog receives these events through the server network connection.

Hosting and security systems may process network addresses and maintain counters to detect and limit excessive traffic. Vercel processes request network information separately from these operational events. Stateless MCP means no persistent protocol session is required; it does not mean hosting security counters or operational records are absent.

## Discovery and documentation

KinToolkit is published in the official MCP Registry as com.kintoolkit/label-reference. Registry publication is separate from inclusion in a client directory; use the setup instructions above to connect directly.

The ARD capability manifest uses the AI Catalog 1.0 model to describe the existing MCP card, OpenAPI schema, calculator reference catalog and agent skill, with example discovery queries. Its media types match the linked resources. The API catalog uses the RFC 9727 JSON linkset format. The MCP server card follows the experimental SEP-1649 discovery format used by current readiness checkers; it is not a finalized MCP standard. MCP initialize and tools/list responses remain authoritative for runtime capabilities and schemas.

# About KinToolkit

Canonical URL: https://kintoolkit.com/about

KinToolkit helps adult caregivers find educational references for selected US liquid medicine bottles. Its free calculators organize published label directions for acetaminophen, ibuprofen and cetirizine by the bottle and label ranges supported on the site.

## Who operates KinToolkit

KinToolkit is operated by Cedar Jay Ventures, LLC. Our published business mailing contact is 1111b South Governors Ave, STE 34330, Dover, DE 19904, United States. Product questions, privacy requests and reports of website problems can be sent to cedarjayventures@gmail.com.

- [Contact KinToolkit](https://kintoolkit.com/contact)

## How the references are prepared

KinToolkit organizes selected US liquid medicine labels into bottle-matching tools and reference tables. The calculator and reference pages use the same predefined range lookup, not a continuous weight formula. Supported bottles include Children’s and Infants’ TYLENOL, Children’s and Infants’ MOTRIN, and Children’s ZYRTEC at the exact concentrations listed on their pages.

Manufacturer labels are the primary sources. Each medicine reference links to its source and keeps the bottle concentration, printed age or weight band, directions and limitations together. A source-check date records when a reference was checked; it is not a clinical-review date or a certification of a dosing protocol. An ask-doctor label outcome remains an instruction to ask the child’s doctor, rather than an estimated amount.

- [TYLENOL manufacturer dosing source](https://www.tylenol.com/safety-dosing/dosage-for-children-infants)
- [MOTRIN manufacturer dosing source](https://www.motrin.com/children-infants/dosing-charts)
- [ZYRTEC manufacturer dosing source](https://www.zyrtec.com/products/zyrtec-dosage-guide)

## Scope and limitations

These references cover only the US liquid products and label ranges shown. They do not establish whether a medicine is suitable for a particular child, diagnose a condition, prescribe treatment, convert between concentrations or replace the full label on the bottle. The site does not reproduce every product warning. For an unsupported bottle, conflicting information or uncertainty, ask a pharmacist or the child’s clinician.

KinToolkit is an independent educational tool and does not establish a healthcare-provider relationship. Product names and trademarks belong to their respective owners; their appearance does not imply manufacturer affiliation or endorsement.

- [Read the Terms of Service](https://kintoolkit.com/terms)

## Privacy and how the site is supported

The calculator does not require an account. Public reference URLs identify a bottle and a published label band; they are not private medical records. Do not include a child’s name, exact measurements or medical history in shared URLs or support messages. The Privacy Policy explains analytics, hosting and information processed when using the site or its public reference tools.

As an Amazon Associate, KinToolkit earns from qualifying purchases. The website may also earn referral fees from eligible appointment bookings. External sellers and healthcare providers control their own services and policies. The current calculator does not charge a usage fee or process payment-card details.

- [Read the Privacy Policy](https://kintoolkit.com/privacy)

## Corrections and developer access

If a reference appears inconsistent with a published label, contact us with the affected public page and source link, without sending personal health information. Developers can use the documented public label-reference service to retrieve supported bottles and printed label rows. It has the same educational scope and is not a personalized dosing service.

# Contact KinToolkit

Canonical URL: https://kintoolkit.com/contact

Contact Cedar Jay Ventures, LLC, the operator of KinToolkit, at cedarjayventures@gmail.com for product questions, website problems, source corrections and privacy requests. This contact is for the educational website and its public reference tools.

## Email support

For a website problem, include the affected page address, the browser or device you used, and a short description of the action that did not work. Describe the interface rather than a child’s situation. Remove personal query parameters and any identifying details before sharing a link or screenshot.

- [cedarjayventures@gmail.com](mailto:cedarjayventures@gmail.com)

## Report a label-source correction

If a public reference appears to disagree with its source, identify the KinToolkit page, the product name and concentration printed on the label, and a link to the manufacturer’s published information. Explain which public wording appears inconsistent. This helps identify the reference that needs attention without sending names, symptoms, exact patient measurements or medical histories.

KinToolkit summarizes selected US labels and does not replace the full label on your bottle. Do not rely on an email exchange to decide whether to give medicine. Ask a pharmacist or the child’s clinician when the product, directions or restrictions are unclear.

## Privacy, security and developer questions

Use the same email address for privacy requests or to report a possible security problem. Describe the issue without sending passwords, access tokens, private conversations or personal health information. Our Privacy Policy explains the site’s information handling and the role of hosting, analytics and third-party services.

For an integration problem, the developer guide describes supported bottles, public label identifiers, connection setup, errors and request limits. You can report the client name, technical error and a reproducible example using public reference identifiers. Do not include credentials or patient information.

- [Privacy Policy](https://kintoolkit.com/privacy)
- [Developer guide](https://kintoolkit.com/developers)

## Medical questions and urgent help

KinToolkit support does not provide diagnosis, prescribing or medical treatment. A reference lookup or support message does not establish a healthcare-provider relationship. Do not delay seeking medical care while waiting for a reply. For an emergency, contact emergency services or your local poison center.

# Privacy Policy

Canonical URL: https://kintoolkit.com/privacy

Effective date: September 24, 2026

KinToolkit is operated by Cedar Jay Ventures, LLC (“we,” “us,” or “our”). This policy describes information handled through kintoolkit.com and our public discovery resources. Contact us at [cedarjayventures@gmail.com](mailto:cedarjayventures@gmail.com) with privacy questions or requests.

## Calculator information

KinToolkit helps adult caregivers locate medicine-label information without creating an account. Public label-reference URLs identify a medicine bottle, concentration and printed weight or age band. Selecting or sharing one of these pages includes that public band in the URL; it is not a private record. Your browser history, anyone receiving the link, and the hosting provider may see that URL. Do not put a child’s name, exact measurements, medical history or other personal information into a link.

Our public catalog and browser discovery tool list educational resources. They do not accept child details or return personalized doses. Please do not include a child's name, medical history, or other sensitive information in URLs or support messages.

Our remote label-reference tools at [/api/mcp](/api/mcp) accept a public product identifier, exact bottle concentration, and published label-band identifier. These tools return the corresponding label reference and do not accept names, exact patient ages or weights, or medical histories. Our server and hosting provider process the request body to answer the call, together with technical request information. KinToolkit does not send MCP arguments or returned directions to PostHog. Your AI assistant or MCP client may also process the information you provide under its own privacy policy. Do not send personal health information to these tools.

We send limited MCP operational records from our server to PostHog to understand use and diagnose reliability problems. Each record contains the protocol operation or supported tool name, technical outcome category, HTTP status, processing time, a test-traffic marker, and a random identifier for that request. These records exclude request and response bodies, tool arguments, returned values, medicine names, concentrations, label bands, caller IP addresses, user-agent and client information, headers, referrers, and query strings. They do not use a persistent client identifier, and person profiles are disabled for these events. PostHog receives the records through our server’s network connection. See the [developer guide](/developers) for the MCP interface and error handling.

## Information collected when you visit or contact us

Our hosting and service providers process technical information needed to deliver and protect the website, such as network addresses, request information, browser details, and timestamps. We use PostHog to understand website usage. The deployed site records pageviews, calculator use with the selected medicine type, and use of its copy-link sharing feature. Before browser analytics are sent, label-reference URLs are reduced to their medicine page, page titles are generalized, and URL fragments and non-allowlisted query parameters are removed. The analytics library also processes browser and device information and persistent identifiers. We do not include selected label bands, child age or weight, concentration or displayed directions in the calculator event payload.

Hosting and security systems may process network addresses and maintain counters to detect and limit excessive traffic. This abuse protection is separate from browser analytics and the MCP operational records described above. Our hosting provider, Vercel, processes the network information needed to receive and protect MCP requests.

We disable session recordings, automatic interaction capture, and heatmaps in the site's analytics configuration. This does not mean all website traffic is anonymous: the name or address of a medicine page can itself reveal health-related interests.

If you email us, we receive your email address and whatever information you provide. We use it to answer your request and maintain necessary correspondence. Do not use support email for urgent medical questions.

## How information is used and shared

We use information to provide and secure the site, diagnose problems, understand which resources are useful, respond to requests, and meet applicable legal obligations. Service providers process information to support those purposes, including website hosting through Vercel, domain/DNS services through Cloudflare, analytics through PostHog, and email services.

We may disclose information when required by law or reasonably necessary to protect people, enforce lawful rights, or investigate abuse. If the business is transferred, relevant information may be transferred subject to applicable law and appropriate notice.

## Browser storage and your choices

Our analytics library uses browser persistence, which can include cookies and local storage, to recognize visits. Browser controls let you block or clear cookies and local storage. Clearing storage does not necessarily remove information already received by a service provider. Contact us about access, correction, deletion, or other privacy rights available under applicable law. We may need proportionate information to verify a request, and some information may be retained where law permits or requires it.

## External sites, purchases, and appointments

KinToolkit links to manufacturers, Amazon, and independent healthcare services, including appointment booking through Square. When you follow a link, the destination's privacy policy applies. Affiliate or referral links may identify KinToolkit as the source of a visit, and we may receive compensation for qualifying purchases or bookings. We do not receive your payment-card details through the KinToolkit calculator.

If you access KinToolkit through an AI assistant or other third-party service, information you give that service is governed by its own policies. KinToolkit's public discovery resources do not require access to your assistant account or conversations.

## Retention, security, and international processing

We keep information for the purposes described here, subject to applicable legal requirements. Retention depends on the type of information, operational need, and provider settings.

We use reasonable safeguards, but no online system is completely secure. Our service providers may process information in the United States and other countries where they operate.

## Children

KinToolkit is intended for adult caregivers, not for children to use independently. We do not ask children to create accounts or submit identifying information. If you believe a child has provided personal information to us, contact us so we can investigate and take appropriate action.

## Changes and contact

We will post revisions here with an updated effective date and provide additional notice where required. Privacy requests: [cedarjayventures@gmail.com](mailto:cedarjayventures@gmail.com). Mailing contact: Cedar Jay Ventures, LLC, 1111b South Governors Ave, STE 34330, Dover, DE 19904, United States.

# Children's Medicine Dosage Calculators

Published by: KinToolkit
Canonical URL: https://kintoolkit.com/
Language: en-US
Label sources checked: 2026-09-24 (source verification, not clinical review)

KinToolkit provides educational children's medicine dosage calculators for acetaminophen, ibuprofen, and cetirizine. Always verify the product concentration and consult a healthcare professional.

## Choose a medicine and match your bottle

Choose the active ingredient, then match the concentration on your own bottle. The tool uses predefined label ranges; it does not calculate a personalized prescription.

## How do I use these calculators?

Match your bottle, choose the weight or age range offered for that product, and read the label directions and warnings. If your bottle or range is not listed, ask a pharmacist or your child’s doctor.


## Supported bottles

| Bottle | Ingredient | Strength | Uses |
| --- | --- | --- | --- |
| Children’s TYLENOL | Acetaminophen | 160 mg / 5 mL | Weight or age |
| Infants’ TYLENOL | Acetaminophen | 160 mg / 5 mL | Weight or age |
| Children’s MOTRIN | Ibuprofen | 100 mg / 5 mL | Weight or age |
| Infants’ MOTRIN | Ibuprofen | 50 mg / 1.25 mL | Weight or age |
| Children’s ZYRTEC | Cetirizine HCl | 1 mg / mL | Age |

US liquid products shown here only. Do not apply these amounts to another strength, formulation or country’s product. Use the measuring device supplied with your bottle and read the full label; this page does not reproduce every warning.

## Methodology and attribution

KinToolkit organizes the selected US liquid medicine labels into bottle-matching tools and reference tables. The calculator and these tables use the same range lookup, not a continuous weight formula. Manufacturer labels are the primary sources; this summary does not establish an independently validated or clinically reviewed dosing protocol.

## Before using label directions

Verify the active ingredient, concentration and warnings on your own package. KinToolkit is an independent educational tool, not a medical professional or a substitute for your child’s clinician. The brands mentioned above are not affiliated with KinToolkit.

# Children's Tylenol Dosage Calculator (Acetaminophen)

Published by: KinToolkit
Canonical URL: https://kintoolkit.com/childrens-tylenol-dosage-calculator
Language: en-US
Label sources checked: 2026-09-24 (source verification, not clinical review)

Find children's acetaminophen label directions using a weight or age range and matching the bottle strength. This educational calculator does not replace the medicine label or advice from a healthcare professional.

## Children’s Tylenol dosage by weight or age

Match the Children’s or Infants’ Tylenol bottle and its printed concentration before choosing a range. The calculator shows label directions for the selected bottle; it does not determine whether acetaminophen is appropriate for your child.

## Does this tool use weight or age?

The Tylenol flow starts with weight ranges and offers an age-range fallback. Read the age assumptions shown in the tool and the full manufacturer guidance before using the directions.


## Supported bottles

| Bottle | Ingredient | Strength | Uses |
| --- | --- | --- | --- |
| Children’s TYLENOL | Acetaminophen | 160 mg / 5 mL | Weight or age |
| Infants’ TYLENOL | Acetaminophen | 160 mg / 5 mL | Weight or age |

US liquid products shown here only. Do not apply these amounts to another strength, formulation or country’s product. Use the measuring device supplied with your bottle and read the full label; this page does not reproduce every warning.

## Children’s TYLENOL — 160 mg / 5 mL

Use weight if known; otherwise use age. The weight and age columns are alternatives from the label, not a formula. If the child is outside the listed age range or the weight falls outside a printed band, ask a clinician. Do not interpolate.

| Weight (lb) | Age on label | Label amount | Label reference |
| --- | --- | --- | --- |
| Under 24 | Under 2 years | Ask your child’s doctor | [Under 24 lb](https://kintoolkit.com/childrens-tylenol-dosage-calculator/160-mg-per-5-ml/under-24-lb) |

# Ibuprofen Dosage Calculator for Children (Motrin)

Published by: KinToolkit
Canonical URL: https://kintoolkit.com/ibuprofen-dosage-calculator
Language: en-US
Label sources checked: 2026-09-24 (source verification, not clinical review)

Find children's ibuprofen label directions using a weight or age range and matching the bottle strength. Do not give ibuprofen to a child younger than 6 months unless a healthcare professional instructs you to do so.

## Pediatric ibuprofen dose calculator by weight or age

Choose the Children’s or Infants’ Motrin bottle and match its concentration. These are separate bottle options in the calculator. Directions for one concentration must not be reused for another.

## Can I switch between Children’s and Infants’ Motrin?

Changing the bottle clears the previous confirmation and range. Confirm the new concentration and choose the appropriate weight or age range again before viewing directions.

## Are Infants’ and Children’s Motrin the same strength?

The US bottles shown here have different strengths: Infants’ Motrin is 50 mg per 1.25 mL; Children’s Motrin is 100 mg per 5 mL. Match the full concentration on your bottle before using its chart. Do not reuse the same liquid amount for a different strength.

## Is this a pediatric ibuprofen mg/kg calculator?

No. KinToolkit looks up the printed label’s weight bands in pounds or its age bands. It does not calculate a continuous mg/kg dose, round a weight into a band, or convert between bottle strengths. If your child falls outside the listed bands, ask a pharmacist or clinician.

## Does this calculator cover adult ibuprofen or other brands?

No. This page covers only the US liquid Motrin bottles listed below. It does not provide adult, tablet, or other-brand directions. Use the label on your own product or ask a pharmacist.

## Supported bottles

| Bottle | Ingredient | Strength | Uses |
| --- | --- | --- | --- |
| Children’s MOTRIN | Ibuprofen | 100 mg / 5 mL | Weight or age |
| Infants’ MOTRIN | Ibuprofen | 50 mg / 1.25 mL | Weight or age |

US liquid products shown here only. Do not apply these amounts to another strength, formulation or country’s product. Use the measuring device supplied with your bottle and read the full label; this page does not reproduce every warning.

## Children’s MOTRIN — 100 mg / 5 mL

Use weight if known; otherwise use age. The weight and age columns are alternatives from the label, not a formula. If the child is outside the listed age range or the weight falls outside a printed band, ask a clinician. Do not interpolate.

| Weight (lb) | Age on label | Label amount | Label reference |
| --- | --- | --- | --- |
| Under 24 | Under 2 years | Ask your child’s doctor | [Under 24 lb](https://kintoolkit.com/ibuprofen-dosage-calculator/100-mg-per-5-ml/under-24-lb) |
| 24–35 | 2–3 years | 5 mL | [24–35 lb](https://kintoolkit.com/ibuprofen-dosage-calculator/100-mg-per-5-ml/24-35-lb) |

Label interval: every 6–8 hours if needed. No more than 4 doses in 24 hours.

## Infants’ MOTRIN — 50 mg / 1.25 mL

Use weight if known; otherwise use age. The weight and age columns are alternatives from the label, not a formula. If the child is outside the listed age range or the weight falls outside a printed band, ask a clinician. Do not interpolate.

| Weight (lb) | Age on label | Label amount | Label reference |
| --- | --- | --- | --- |
| Under 12 | Under 6 months | Ask your child’s doctor | [Under 12 lb](https://kintoolkit.com/infant-ibuprofen-dosage-calculator/50-mg-per-1-25-ml/under-12-lb) |

# Cetirizine Pediatric Dose Calculator (Zyrtec)

Published by: KinToolkit
Canonical URL: https://kintoolkit.com/cetirizine-pediatric-dose-calculator
Language: en-US
Label sources checked: 2026-09-24 (source verification, not clinical review)

Find children's cetirizine label directions using an age range and matching the bottle strength. This educational calculator does not replace the medicine label or advice from a healthcare professional.

## Children’s Zyrtec (cetirizine) dosage by age

Match the Children’s Zyrtec bottle and its printed concentration, then choose an age range. This calculator uses age ranges for cetirizine; it does not use a child’s weight to generate a dose.

## Which age ranges can I select?

The cetirizine flow offers Under 2 years, 2–5 years, and 6–11 years. Selecting Under 2 directs you to ask your child’s doctor. For other ages or an unlisted bottle, ask a pharmacist or doctor.

## Is children’s Zyrtec dosing by weight or age?

The US Children’s Zyrtec syrup label uses age groups. This tool follows those groups, not weight or a cetirizine mg/kg formula. Match the 1 mg/mL syrup and read the full label.

## Can I use this calculator for a 10-month-old baby?

For children under 2 years, including a 10-month-old, the label says to ask a doctor. This calculator shows no infant dose. Ask your child’s clinician rather than calculating an amount from weight.

## Supported bottles

| Bottle | Ingredient | Strength | Uses |
| --- | --- | --- | --- |
| Children’s ZYRTEC | Cetirizine HCl | 1 mg / mL | Age |

US liquid products shown here only. Do not apply these amounts to another strength, formulation or country’s product. Use the measuring device supplied with your bottle and read the full label; this page does not reproduce every warning.

## Children’s ZYRTEC — 1 mg / mL

Use age for this product. The 6–11 row reflects this tool’s scope; the manufacturer’s full guide also covers older ages.

| Age | Label amount | Label reference |
| --- | --- | --- |
| Under 2 years | Ask your child’s doctor | [Under 2 years](https://kintoolkit.com/cetirizine-pediatric-dose-calculator/1-mg-per-ml/under-2-years) |
| 2–5 years | 2.5 mL | [2–5 years](https://kintoolkit.com/cetirizine-pediatric-dose-calculator/1-mg-per-ml/2-5-years) |
| 6–11 years | 5 mL or 10 mL | [6–11 years](https://kintoolkit.com/cetirizine-pediatric-dose-calculator/1-mg-per-ml/6-11-years) |

2–5 years: The label starts at 2.5 mL once daily. If needed, it allows up to 5 mL once daily or 2.5 mL every 12 hours. Maximum 5 mL in 24 hours.

6–11 years: The label specifies 5 or 10 mL once daily, depending on symptom severity. Maximum 10 mL in 24 hours. Follow the label or ask your pharmacist.

Ask a doctor before use with liver or kidney disease. Ask a doctor or pharmacist about sedatives or tranquilizers. Drowsiness may occur; read all package warnings.

An infant Tylenol calculator for the US 160 mg/5 mL bottle. For children under 2 years or under 24 lb, the label directs caregivers to a healthcare provider rather than a calculated dose.

## Infants’ Tylenol dosage chart and age limits

Match the 160 mg/5 mL concentration. This page selects the infant bottle and shows its label ranges. The infant branding does not mean a dose is listed for every baby.

## Is infant Tylenol the same concentration as children’s Tylenol?

The US liquids shown here both contain 160 mg per 5 mL. Follow the directions and use the measuring device supplied with your own bottle; do not apply this chart to another strength.

An infant ibuprofen calculator for US Infants’ Motrin concentrated drops. Match the 50 mg/1.25 mL bottle before selecting a printed weight or age range.

## Infant Motrin dosage by weight or age

The infant chart lists 6–11 months and 12–23 months. For babies under 6 months, ask a healthcare provider. Do not reuse a liquid amount from Children’s Motrin: its concentration differs.

## How do infant and children’s Motrin differ?

Infants’ drops contain 50 mg per 1.25 mL; Children’s suspension contains 100 mg per 5 mL. Select the actual bottle and use its supplied measuring device. The tool does not convert doses between concentrations.
