Parent's Safety Checklist
Use the tool provided with the medicine
Never use a kitchen spoon. Always use the syringe or dosing cup that came in the box to ensure 0.1mL accuracy.
Dose by weight, not by age
Age ranges on packages are estimates. Weight-based dosing is the gold standard for pediatric clinical safety.
Wait the full time between doses
Acetaminophen (Tylenol) must wait 4-6 hours. Ibuprofen (Motrin) must wait 6-8 hours. Doubling up can lead to liver or kidney strain.
