Feldene Side Effects Center
Medical Editor: John P. Cunha, DO, FACOEP
Feldene (piroxicam) is a nonsteroidal anti-inflammatory drug (NSAID) indicated for the relief of the signs and symptoms of osteoarthritis and rheumatoid arthritis. Side effects of Feldene are swelling, anorexia, abdominal pain, constipation, diarrhea, indigestion, heartburn, upset stomach, stomach pain, elevated liver enzymes, bloating, gas, gross bleeding/perforation, heartburn, nausea, ulcers (gastric/duodenal), dizziness, headache, nervousness, skin itching or rash, blurred vision, ringing in your ears, and vomiting.
Feldene is administered orally in the form of capsules. To minimize the potential risk for an adverse CV event in patients treated with an NSAID, the lowest effective dose should be used for the shortest duration possible. Physicians and patients should remain alert for the development of cardiovascular (CV) thrombotic events, myocardial infarction, and stroke, even in the absence of previous CV symptoms. In late pregnancy, as with other NSAIDs, Feldene should be avoided because it may cause premature closure of the ductus arteriosus.
Our Feldene Side Effects Drug Center provides a comprehensive view of available drug information on the potential side effects when taking this medication.
