Ibuprofen is used for the relief of mild to moderate pain including pain in the joints and muscles, backache, pain in the nerve (neuralgia), headache, migraine (one-sided headache), dental pain, body pain, pain during the menstrual cycle, pain during menstruation (dysmenorrhea), as well as to treat fever and symptoms of cold and influenza.

Ibuprofen belongs to the group of medicines called nonsteroidal anti-inflammatory drugs (NSAIDs). It relieves pain by blocking production of a certain natural substance (prostaglandin) that is released in the body during pain.

What is ibuprofen?

Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID). It works by reducing hormones that cause inflammation and pain in the body. Ibuprofen is used to reduce fever and treat pain or inflammation caused by many conditions such as headache, toothache, back pain, arthritis, menstrual cramps, or minor injury. Ibuprofen is used in adults and children who are at least 6 months old.

Important information

Ibuprofen can increase your risk of fatal heart attack or stroke, especially if you use it long term or take high doses, or if you have heart disease. Do not use this medicine just before or after heart bypass surgery (coronary artery bypass graft, or CABG). Ibuprofen may also cause stomach or intestinal bleeding, which can be fatal. These conditions can occur without warning while you are using ibuprofen, especially in older adults. Do not take more than your recommended dose. An ibuprofen overdose can damage your stomach or intestines. Use only the smallest amount of medication needed to get relief from your pain, swelling, or fever.

Before taking this medicine

Ibuprofen can increase your risk of fatal heart attack or stroke, especially if you use it long term or take high doses, or if you have heart disease. Even people without heart disease or risk factors could have a stroke or heart attack while taking this medicine. Do not use this medicine just before or after heart bypass surgery (coronary artery bypass graft, or CABG). Ibuprofen may also cause stomach or intestinal bleeding, which can be fatal. These conditions can occur without warning while you are using ibuprofen, especially in older adults. You should not use ibuprofen if you are allergic to it, or if you have ever had an asthma attack or severe allergic reaction after taking aspirin or an NSAID.

Ask a doctor or pharmacist if it is safe for you to take this medicine if you have: heart disease, high blood pressure, high cholesterol, diabetes, or if you smoke; a history of heart attack, stroke, or blood clot; a history of stomach ulcers or bleeding; asthma; liver or kidney disease; fluid retention; or a connective tissue disease such as Marfan syndrome, Sjogren’s syndrome, or lupus.

Taking ibuprofen during the last 3 months of pregnancy may harm the unborn baby.Do not use this medicine without a doctor’s advice if you are pregnant. It is not known whether ibuprofen passes into breast milk or if it could harm a nursing baby. Do not use this medicine without a doctor’s advice if you are breast-feeding a baby.

Do not give ibuprofen to a child younger than 2 years old without the advice of a doctor.

How should I take ibuprofen?

Use ibuprofen exactly as directed on the label, or as prescribed by your doctor. Do not use in larger amounts or for longer than recommended. Use the lowest dose that is effective in treating your condition. Do not take more than your recommended dose. An ibuprofen overdose can damage your stomach or intestines. The maximum amount of ibuprofen for adults is 800 milligrams per dose or 3200 mg per day (4 maximum doses). Use only the smallest amount needed to get relief from your pain, swelling, or fever. A child’s dose of ibuprofen is based on the age and weight of the child. Carefully follow the dosing instructions provided with your child’s medicine for the age and weight of your child. Ask a doctor or pharmacist if you have questions.

Take ibuprofen with food or milk to lessen stomach upset. Shake the oral suspension (liquid) well just before you measure a dose. Measure liquid medicine with the dosing syringe provided, or with a special dose-measuring spoon or medicine cup. If you do not have a dose-measuring device, ask your pharmacist for one. The ibuprofen chewable tablet must be chewed before you swallow it. If you use this medicine long-term, you may need frequent medical tests. Store at room temperature away from moisture and heat. Do not allow the liquid medicine to freeze. Read all patient information, medication guides, and instruction sheets provided to you. Ask your doctor or pharmacist if you have any questions.

What happens if I miss a dose?

Since ibuprofen is used when needed, you may not be on a dosing schedule. If you are on a schedule, use the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not use extra medicine to make up the missed dose.

What happens if I overdose?

Seek emergency medical attention or call the Poison Help line at 1-800-222-1222. Overdose symptoms may include nausea, vomiting, stomach pain, drowsiness, black or bloody stools, coughing up blood, shallow breathing, fainting, or coma.

What should I avoid while taking ibuprofen?

Avoid drinking alcohol. It may increase your risk of stomach bleeding. Avoid taking aspirin while you are taking ibuprofen. Avoid taking ibuprofen if you are taking aspirin to prevent stroke or heart attack. Ibuprofen can make aspirin less effective in protecting your heart and blood vessels. If you must use both medications, take the ibuprofen at least 8 hours before or 30 minutes after you take the aspirin (non-enteric coated form). Ask a doctor or pharmacist before using any cold, allergy, or pain medicine. Many medicines available over the counter contain aspirin or other medicines similar to ibuprofen. Taking certain products together can cause you to get too much of this type of medication. Check the label to see if a medicine contains aspirin, ibuprofen, ketoprofen, or naproxen.
