How to read children’s medicine labels
A parent-friendly guide to active ingredients, strength, concentration, and duplicate medicine checks before giving children’s medicine.
Last reviewed by the PedsCalc editorial team:
Start with the active ingredient
The active ingredient is the part of the medicine that causes the intended effect. Brand names and package colors can change, but the active ingredient tells you what medicine is actually inside.
Before giving a medicine, compare the active ingredient on the front and Drug Facts label with any instructions from your clinician or pharmacist. If the name does not match what you expected, pause and ask before giving it.
Watch for duplicate active ingredients
Some cough, cold, pain, fever, allergy, and multi-symptom products can contain the same active ingredient as another bottle in the house. Giving two products with the same active ingredient can accidentally give too much medicine.
Do not combine medicines just because the brand names look different. Ask your pediatrician or pharmacist before using more than one medicine at the same time, especially multi-symptom products.
Check strength and concentration before measuring
Labels may describe strength or concentration with numbers such as mg per tablet, mg per chewable, or mg per 5 mL of liquid. Those numbers affect how much medicine is in each tablet, chewable, or measured liquid amount.
If a bottle, refill, or store brand has a different concentration than the one your instructions were based on, the measured amount may not be the same. Ask a pharmacist to confirm the exact product and amount before using old instructions with a new bottle.
Read warnings, age limits, and directions together
The Drug Facts label can include age limits, maximum daily amounts, warnings, inactive ingredients, and when to ask a doctor. These details matter because a product that is common for one child may not be right for another.
If the label says to ask a doctor for your child’s age, weight, symptoms, medical condition, or other medicines, treat that as a stop sign and call your child’s clinician or pharmacist before giving it.
More parent guides
Ask your pharmacist or pediatrician before combining medicines
Ask your pharmacist or pediatrician if you are using more than one medicine, switching brands, using a multi-symptom product, following instructions from an older bottle, or cannot tell whether two products share the same active ingredient.
Do not guess based on color, flavor, brand family, or package size. Use the active ingredient, strength, concentration, and your child’s current instructions to confirm the plan.
If too much medicine may have been given
If you think too much medicine may have been given, call Poison Control at 1-800-222-1222 in the U.S. or use Poison Control online right away rather than waiting for symptoms to appear.
Seek urgent or emergency care if your child has trouble breathing, is difficult to wake, has a seizure, has blue or gray lips, has swelling of the face or tongue, or you are worried something is seriously wrong.
