Duexis Side Effects

October 12th, 2012 by Rita Jones

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.

Do not use Duexis just before or after heart bypass surgery (coronary artery bypass graft, or CABG).

Ibuprofen may cause life-threatening heart or circulation problems such as heart attack or stroke, especially if you use it long term.

Ibuprofen may also cause serious effects on the stomach or intestines, including bleeding or perforation (forming of a hole). These conditions can be fatal and can occur without warning, especially in older adults.

You should not use Duexis if you are allergic to ibuprofen (Advil, Motrin) or famotidine (Pepcid), or if you have:

  • if you are allergic to other stomach acid reducers such as ranitidine (Zantac), cimetidine (Tagamet), or nizatidine (Axid); or
  • if you are more than 29 weeks (7 months) pregnant.
