Famotidine decreases the amount of acid the stomach produces.

Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that reduces hormones that cause inflammation and pain.

Famotidine and ibuprofen is a combination drug. Ibuprofen treats the symptoms of arthritis. Famotidine helps reduce the risk of ulcers in the stomach or intestines that can be caused by long-term use of ibuprofen.

Taking famotidine (Pepcid) and ibuprofen (Advil, Motrin) together does not have the same effect as using the combination medicine.

Famotidine and ibuprofen may also be used for purposes not listed in this medication guide.

You should not use this medicine if you are allergic to famotidine or ibuprofen, or if you have ever had an asthma attack or severe allergic reaction after taking aspirin or an NSAID.

Ibuprofen can increase your risk of fatal heart attack or stroke, even if you don't have any risk factors. 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 famotidine and ibuprofen, especially in older adults.

Tell your doctor if you have ever had:

• heart disease, high blood pressure;
• bleeding problems;
• liver or kidney disease;
• a stomach or intestinal disorder;
• a connective tissue disease such as Marfan syndrome, Sjogren's syndrome, or lupus;
• asthma; or
• if you smoke or drink alcohol.

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 possible complications with your pregnancy.

It may not be safe to breastfeed while using this medicine. Ask your doctor about any risk.

Famotidine and ibuprofen is not approved for use by anyone younger than 18 years old.

Use Famotidine And Ibuprofen (Duexis) exactly as directed on the label, or as prescribed by your doctor. Do not use in larger or smaller amounts or for longer than recommended.

Get emergency medical help if you have signs of an allergic reaction (sneezing, runny or stuffy nose; wheezing or trouble breathing, swelling in your face or throat) or a severe skin reaction (fever, sore throat, burning eyes, skin pain, red or purple skin rash with blistering and peeling).

Get emergency medical help if you have signs of a heart attack or stroke: chest pain spreading to your jaw or shoulder, sudden numbness or weakness on one side of the body, slurred speech, leg swelling, feeling short of breath.

• changes in your vision;
• the first sign of any skin rash, no matter how mild;
• fever, headache, neck stiffness, increased sensitivity to light, nausea, vomiting, confusion, drowsiness;
• severe headache, blurred vision, pounding in your neck or ears;

• low red blood cells (anemia)--pale skin, unusual tiredness, feeling light-headed or short of breath, cold hands and feet; or
• signs of stomach bleeding--bloody or tarry stools, coughing up blood or vomit that looks like coffee grounds.

Some side effects may be more likely in older adults and in people who have severe kidney disease.

Common side effects may include:

• nausea, stomach pain;
• diarrhea, constipation; or
• headache.

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.

Ask a doctor or pharmacist before using other medicines for pain, fever, swelling, or cold/flu symptoms. They may contain ingredients similar to ibuprofen (such as aspirin, ketoprofen, or naproxen).

Avoid using other medications that contain ibuprofen.

Avoid drinking alcohol. It may increase your risk of stomach bleeding.
