Pediatric Acetaminophen (Tylenol® or Tempra®) Dosing Using Tablets

Acetaminophen tablets may be split, then crushed, and mixed with apple sauce or pudding. Use split and mixed doses immediately. These calculations use a dose of 15 mg/kg. Doses can be repeated after 4 hours or longer. Do not give more than 5 doses in 24 hours.

Acetaminophen (Tylenol®) comes in 325mg and 500mg tablets. Please note the strength of the tablets. Acetaminophen also comes in different shapes. It is best to use round tablets if you need ¼ of a pill. Pharmacies sell pill cutters if cutting tablets is difficult.

Note: Acetaminophen is not the same as ibuprofen (Advil®, Motrin®) or ASA (Aspirin®). Please verify which medicine you are using. Avoid using ASA or aspirin in children.
