Infant Tylenol Dosage
Calculate infant Tylenol (acetaminophen) dosage by weight and age. Free pediatric tool with liquid volume and tablet dosing for fever and pain relief.
About This Calculator
The Infant Tylenol Dosage Calculator helps parents and caregivers determine the correct dose of Tylenol (acetaminophen/paracetamol) for their child based on weight and age. Using the standard medical guideline of 15 mg per kilogram of body weight per dose, this tool provides precise dosing recommendations for liquid suspensions, chewable tablets, and dissolve packs.
Tylenol is one of the most commonly used medications for reducing fever and relieving mild to moderate pain in children. The active ingredient, acetaminophen (called paracetamol in India and the UK), is recommended by the World Health Organization (WHO) for treating fevers above 38.5°C (101.3°F) in children. The dosage is calculated at 10-15 mg per kg of body weight per dose, given every 4-6 hours, with a maximum of 5 doses (75 mg/kg) in 24 hours.
All infant and children's Tylenol products contain 160 mg of acetaminophen per 5 ml (liquid suspensions) or 160 mg per tablet/powder. The calculator converts the weight-based dose into the appropriate volume of liquid or number of solid doses needed.
