Brand Names: Duexis

What is Duexis?

Duexis contains a combination of famotidine and ibuprofen. Famotidine is a histamine blocker. Famotidine works by decreasing the amount of acid the stomach produces.

Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID). Ibuprofen works by reducing hormones that cause inflammation and pain in the body.

Duexis is a combination drug used to treat osteoarthritis and rheumatoid arthritis. 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.

Duexis may also be used for purposes not listed in this medication guide.

Important information

You should not use Duexis if you are allergic to ibuprofen (Advil, Motrin), famotidine (Pepcid), aspirin, other NSAIDs (non-steroidal anti-inflammatory drugs), or other stomach acid reducers (such as Tagamet, Zantac, or Axid). Do not use Duexis if you are more than 29 weeks (7 months) pregnant. Taking ibuprofen during this time may harm the unborn baby.

Before you take Duexis, tell your doctor if you have a stomach or intestinal disorder, heart disease, high blood pressure, asthma, nasal polyps, liver or kidney disease, lupus, a bleeding or blood-clotting disorder, or a history of heart attack, stroke, or blood clot.

How should I take Duexis?

Take Duexis exactly as prescribed by your doctor. Do not take in larger or smaller amounts or for longer than recommended. Follow the directions on your prescription label.

Duexis is usually taken 3 times each day. Follow your doctor's instructions.

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 of ibuprofen needed to get relief from your pain, swelling, or fever. Do not crush, chew, or break a Duexis tablet. Swallow it whole.

If you have hypertension, your blood pressure will need to be checked often. If you use Duexis long-term, your doctor may want to check you on a regular basis to make sure this medication is not causing harmful effects. Visit your doctor regularly.

If you also use a steroid medication, do not stop using it suddenly or you may have unpleasant withdrawal symptoms. Talk with your doctor about using less and less of the steroid before stopping completely.

Store Duexis at room temperature away from moisture and heat. Keep the bottle tightly closed when not in use.

What happens if I miss a dose?

Take the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not take extra medicine to make up the missed dose.

Overdose symptoms may include severe dizziness, rapid back and forth eye movements, pale skin and blue lips or fingernails, and fainting.

What should I avoid?

Avoid using other medications that contain ibuprofen.

Ask a doctor or pharmacist before using any other cold, allergy, or pain medicine. Ibuprofen and other NSAIDs are contained in many combination medicines.
