Frequently asked questions
How much acetaminophen or ibuprofen can I give my child?
Dosing is by weight (about 15 mg/kg for acetaminophen, 10 mg/kg for ibuprofen). Pick your product's strength to see the exact mL — then confirm with your pediatrician or pharmacist.
How do I measure the liquid?
Always use the syringe or cup that comes with the medicine, never a kitchen spoon, and don't combine products that contain the same drug.
