Before Giving Any Medicine

  • Use the child’s current weight whenever possible.
  • Confirm the active ingredient, formulation and concentration every time.
  • Measure liquid medicine in milliliters with the supplied dosing device—not a kitchen spoon.
  • Do not combine medicines that contain the same active ingredient.
  • Call the child’s pediatrician or pharmacist if the product or dose is uncertain.

Frequently Asked Questions

Should children’s medicine be dosed by weight or age?
Current weight is usually preferred because children of the same age can differ substantially in size. Age limits still apply, and the current Drug Facts label should always be followed.
Can I use the same dosing device for different medicines?
Keep each supplied dosing device with its original medicine. Devices can use different markings and capacities, so mixing them can cause measurement errors.
Can Tylenol and ibuprofen be given together?
Do not routinely combine or alternate medicines unless your child’s clinician gives you a clear plan. Medication schedules can become confusing and increase the risk of dosing mistakes.
What should I do if I gave too much medicine?
In the United States, call Poison Control immediately at 1-800-222-1222. Do not wait for symptoms. Call 911 if the child collapses, has a seizure, has trouble breathing or cannot be awakened.
