Tylenol (acetaminophen) is one of the most commonly used pain relievers and fever reducers worldwide. It is available in many forms including regular strength tablets (325 mg), extra strength caplets (500 mg), 8-hour arthritis formulations (650 mg), children's oral suspensions, chewable tablets, and dissolve packs. This calculator uses the standard medical dosing guidelines of 10-15 mg per kg of body weight per dose, with a maximum of 60 mg per kg per day (not exceeding 4000 mg for adults).
Dosing Guidelines
The calculator applies the following medically-accepted formula: Single Dose (mg) = Weight (kg) × 15 mg/kg, rounded to the nearest whole milligram. The maximum daily dose is calculated as Max Daily (mg) = min(Weight × 60 mg/kg, 4000 mg). Dosing frequency is every 4-6 hours, not exceeding 5-6 doses per 24-hour period depending on the product.
Safety Information
Acetaminophen is safe when used as directed, but exceeding the recommended dose can cause severe liver damage. Adults over 65 should limit daily intake to 3000 mg. Children under 2 years should only receive Tylenol under medical supervision. Always read the product label and consult your healthcare provider if you have liver disease or consume more than 3 alcoholic drinks per day.
