What is ibuprofen?

Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that helps lower fever and relieve pain.

NeoProfen is used in premature babies to treat a condition called patent ductus arteriosus (an abnormal blood vessel opening that usually closes shortly after birth).

Ibuprofen may also be used for reasons that are not mentioned in this medication guide.

Before taking this medicine

Ibuprofen can increase your risk of having a fatal heart attack or stroke. 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. This can happen without warning, especially in older adults.

You should not be treated with 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.

Tell your doctor if you have ever had:

  • heart disease, high blood pressure, high cholesterol, diabetes, or if you smoke;
  • a heart attack, stroke, or blood clot;
  • 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.

If you are pregnant, you should not take ibuprofen unless your doctor tells you to. Taking an NSAID during the last 20 weeks of pregnancy can cause serious heart or kidney problems in the unborn baby and may lead to complications with your pregnancy.

Ask a doctor if it is safe to breastfeed while using this medicine.

Common questions about ibuprofen

Meloxicam vs Ibuprofen: What's the difference?
Meloxicam is stronger, prescription-only, longer-acting, and used mainly for arthritis; ibuprofen is milder, OTC, shorter-acting, and treats various pains. Continue reading
Naproxen vs ibuprofen: What's the difference?
Ibuprofen is short acting, while naproxen is long acting and more likely to cause an upset stomach. Naproxen also increases the risk of uncontrolled bleeding in people taking blood thinners by 4-fold, and ibuprofen increases the risk 2-fold. Naproxen and ibuprofen are both NSAIDs so they are similar in many ways, but there are important differences. Continue reading
Can you take ibuprofen on an empty stomach?
Despite the common belief that you must take ibuprofen with food, you can safely take low-dose ibuprofen (up to 1200 mg daily in divided doses for 1 to 7 days) on an empty stomach, and this provides faster pain relief than taking ibuprofen with food. Food slows ibuprofen absorption time, although it doesn't affect the total amount absorbed. There is actually no scientific evidence that taking ibuprofen with food prevents stomach irritation. Over-the-counter ibuprofen doses have a low incidence of gastric problems anyway. Continue reading
Can you take expired ibuprofen?
Although taking expired ibuprofen is not recommended by the manufacturer, the actual shelf-life is likely to be longer than that indicated by the expiry date, with FDA testing showing many drugs are active for years beyond their expiry date, although specific data on ibuprofen is not available. Within reason, an ibuprofen tablet that is a few months past its expiry date is probably safe to take. Ibuprofen that is years past its expiry date should not be taken. Continue reading
Can You Take Tramadol with Acetaminophen, Ibuprofen, or Aspirin?
Yes, for most people, tramadol can be safely combined with acetaminophen, ibuprofen, or aspirin, and doing so can provide better pain relief than either medicine alone. However, there are important age restrictions and clinical considerations to be aware of. Continue reading
What's the difference between aspirin and ibuprofen?
Both aspirin and ibuprofen are popular NSAIDs (nonsteroidal anti-inflammatory drugs) that work by blocking prostaglandin production to reduce pain and inflammation. However, these over-the-counter pain relievers have important differences in safety, uses, and side effects. Continue reading
Can you overdose on ibuprofen?
Despite ibuprofen having a wide safety margin, it is possible to overdose on it, but death from ibuprofen overdose is rare. Children are more susceptible to the effects of ibuprofen and likely to experience an overdosage of ibuprofen if dosages of more than 400mg/kg (in the range of 8000mg for a 20kg child [the equivalent of 40 x 200mg ibuprofen tablets]) are ingested. Studies have reported patients ingesting less than 99 mg/kg are unlikely to have symptoms. Continue reading
How much ibuprofen can I take and how often?
Adults can safely take ibuprofen 200 mg to 400 mg (one or two tablets) every 4-6 hours as needed for pain relief. The maximum dose in 24 hours for over-the-counter ibuprofen is 1200 mg (6 tablets of 200 mg each). Ibuprofen is also available on a prescription from a doctor and may be prescribed at a higher strength (600 mg or 800 mg every 6 hours) for severe pain. Continue reading
