Kids Medication Dosage

Enter your child's weight and age in months. We'll return a per-dose RANGE in mg and in mL/tablets for the formulation you have, plus how often it can be re-dosed and the daily max. Range, not single number — pediatric dosing has legitimate range variation.

References. Acetaminophen 10–15 mg/kg every 4–6 hours, max 5 doses / 24 hr. Ibuprofen 5–10 mg/kg every 6–8 hours, max 4 doses / 24 hr. Diphenhydramine 1 mg/kg every 6 hours, max 4 doses / 24 hr (FDA OTC labeling restricts unsupervised use to 6+ years). Cetirizine and Loratadine: once daily, age-banded dosing per OTC labeling. All consistent with American Academy of Pediatrics guidance and US OTC manufacturer labelling. We deliberately do not include prescription pediatric meds — those need a clinician's oversight.
