Ibuprofen dosing for children

Ibuprofen is a type of nonsteroidal anti-inflammatory drug (NSAID). It can help:

• Reduce aches, pain, sore throat, or fever in children with a cold or the flu
• Relieve headaches or toothaches
• Reduce pain and swelling from an injury or broken bone

Ibuprofen can be taken as liquid or chewable tablets. To give the correct dose, you need to know your child's weight.

You also need to know how much ibuprofen is in the product you are using. You can read the label to find out.

• For chewable tablets, the label will tell you how many milligrams (mg) are found in each tablet, for example, 100 mg per tablet.
• For liquids, the label will tell you how many mg are found in 1.25 mL or in 5mL. For example, the label may read 50 mg/1.25 mL, or 100 mg/5 mL.

For liquids, you need some type of dosing syringe. It may come with the medicine, or you can ask your pharmacist. Make sure to clean it after every usage.

There are important child medicine safety tips to follow.

• Carefully read all of the instructions on the label before giving your child medicine.
• Make sure you know the strength of the medicine in the bottle you purchased.
• Use the syringe, dropper, or dosing cup that comes with your child's liquid medicine. You can also get one at your local pharmacy.
• Make sure you are using the right unit of measurement when filling medicine. You may have the option of milliliters (mL) or teaspoon (tsp) dosing.
• If you are not sure what medicine to give your child, contact your provider.

Children with certain medical conditions or taking certain medicines should not take ibuprofen. Check with your provider.

Be sure to post the number for the poison control center by your home phone. If you think your child has taken too much medicine, call the poison control center at 1-800-222-1222. It is open 24 hours a day. Signs of poisoning include nausea, vomiting, fatigue, and abdominal pain.

Go to the nearest emergency room. Your child may need:

• Activated charcoal. Charcoal stops the body from absorbing the medicine. It has to be given within an hour. It does not work for every medicine.
• To be admitted to the hospital to be monitored.
• Blood tests to see what the medicine is doing.
• To have his or her heart rate, breathing rate, and blood pressure monitored.

Contact your provider if:

• You are not sure what dose of medicine to give your infant or child.
• You are having trouble getting your child to take medicine.
• Your child's symptoms do not go away when you would expect.
• Your child is an infant and has signs of illness, such as fever.
