## Check formulation and warnings

This answer covers the syrup, not a chewable or dissolve tablet. Use the enclosed dosing cup. Ask a doctor before use with liver or kidney disease, and ask a doctor or pharmacist about sedatives or tranquilizers. Drowsiness may occur. Read all warnings on the package; this page does not reproduce every warning.
