Children can take ibuprofen tablets at age 7 and older

Ibuprofen tablets are approved for children ages 7 and up in the United States. Before age 7, ibuprofen comes only as a liquid suspension (a measured dose you pour), not as a tablet. If your child is under 7 and needs ibuprofen, liquid suspension is the correct form—tablets are a choking hazard and the dose cannot be measured accurately by breaking them.

The reason for this age cutoff is practical: children under 7 typically cannot reliably swallow tablets without choking, and their smaller body weight requires smaller, more precise doses. Tablets are harder to divide accurately than liquid, which is why manufacturers do not make tablet formulations for younger children.

Key Takeaways

  • Ibuprofen tablets are approved for children ages 7 and older; younger children need liquid suspension instead.
  • The standard dose for children 7 and up is based on weight, not age, so check the package label for your child's weight range.
  • Do not give ibuprofen to children under 6 months old under any circumstances; acetaminophen is the only option for that age group.
  • Tablets should never be given to a child who cannot swallow them reliably, even if they are older than 7.

How to find the right dose for your child's weight

Ibuprofen dosing for children is based on weight, not age. The standard dose is 5 to 10 milligrams per kilogram of body weight, given every 6 to 8 hours, with a maximum of 40 milligrams per kilogram per day. In practice, this means you need to know your child's weight and then match it to the dosing chart on the package label.

Most children's ibuprofen tablets come in 100 mg strength. A 7-year-old typically weighs between 40 and 60 pounds (18 to 27 kilograms), which usually means one tablet per dose. However, the package label is your actual guide—do not estimate. If your child's weight falls between two dose ranges on the label, ask a pharmacist which dose is correct rather than guessing.

Ibuprofen is not safe for all children, even at the right age

Even though ibuprofen is approved for age 7 and up, certain children should not take it. Do not give ibuprofen to a child who has asthma, kidney disease, stomach ulcers, or a bleeding disorder. If your child takes other medications, check with a pharmacist before giving ibuprofen, because it can interact with some drugs and increase the risk of stomach bleeding or kidney problems.

Ibuprofen should also be avoided if your child is dehydrated or has been vomiting. Dehydration combined with ibuprofen raises the risk of kidney injury. If your child has a fever from vomiting or diarrhea, acetaminophen is the safer choice until they are rehydrated.

What to do if your child is under 7 and needs pain or fever relief

If your child is between 6 months and 7 years old, ibuprofen liquid suspension is the correct form. The dose is still based on weight, and the bottle will have a dosing chart. Measure the dose carefully using the syringe or measuring spoon that comes with the bottle—do not use a kitchen spoon, which is not accurate.

If your child is under 6 months old, ibuprofen is not an option at all. Acetaminophen is the only fever or pain reliever approved for infants under 6 months. Always check the label for the correct dose by weight, and call your pediatrician if your infant has a fever, because fever in very young babies can signal a serious infection that needs medical evaluation.

How long ibuprofen takes to work and when to call a doctor

Ibuprofen tablets usually begin to reduce fever or pain within 30 minutes to an hour. The effect peaks around 1 to 2 hours after taking the dose. If your child's fever or pain has not improved after 2 hours, do not give another dose early—wait the full 6 to 8 hours between doses.

Call your child's doctor if fever lasts longer than 3 days, if pain is severe or does not improve with ibuprofen, or if your child develops a rash, vomiting, or difficulty breathing. These can be signs of a condition that needs medical attention beyond over-the-counter pain relief.

Storing ibuprofen tablets safely away from children

Keep ibuprofen tablets in a locked cabinet or high shelf out of reach of younger siblings or other children in your home. Ibuprofen overdose in young children can cause serious stomach bleeding and kidney damage. If a child swallows more than the recommended dose, call Poison Control at 1-800-222-1222 when ready.

Store tablets in their original labeled container so you always know the strength and can tell a doctor or poison control exactly what was taken. Do not transfer them to an unlabeled bottle, where the dose could be confused with a different medication.

Frequently Asked Questions

Can I give my 5-year-old ibuprofen tablets if they are small?

No. Ibuprofen tablets are not approved for children under 7, regardless of size. Tablets are a choking hazard and cannot be dosed accurately by breaking them. Use ibuprofen liquid suspension instead, which is dosed by weight on the label.

What if my child cannot swallow tablets?

Some children over 7 have difficulty swallowing tablets. If your child is 7 or older but cannot reliably swallow a tablet, continue using ibuprofen liquid suspension. There is no age at which a child must switch to tablets if they cannot swallow them safely.

Is it safe to alternate ibuprofen and acetaminophen?

Alternating the two medications is sometimes recommended by pediatricians for high fevers, but only under their guidance. Do not alternate on your own without talking to your doctor first, because it is straightforward to accidentally overdose if you lose track of timing between doses.

Can I crush an ibuprofen tablet and mix it with food?

Do not crush ibuprofen tablets. Crushing can change how the medication is absorbed and make the dose unpredictable. If your child cannot swallow a tablet, use the liquid suspension form instead, which is designed to be mixed with food or drink if needed.

What should I do if my child takes too much ibuprofen?

Call Poison Control when ready at 1-800-222-1222. Have the bottle in front of you so you can tell them the strength and how much your child took. Do not wait to see if symptoms develop—ibuprofen overdose can cause serious internal bleeding even if your child seems fine at first.
