Feldene
Feldene (generic name: Piroxicam) is a nonsteroidal anti-inflammatory drug (NSAID) that is effective in treating fever, pain, and inflammation in the body. As a group, NSAIDs are non-narcotic relievers of mild to moderate pain of many causes, including injury, menstrual cramps, arthritis, and other musculoskeletal conditions. NSAIDs, including piroxicam, block the enzyme in the body that makes prostaglandins (cyclooxygenase), resulting in lower levels of prostaglandins. Prostaglandins are responsible for causing many types of pain, fever and inflammation. As a consequence of taking NSAIDs, inflammation, pain and fever are reduced. The FDA approved piroxicam in 1982.
Feldene Piroxicam generally is used with caution in patients taking blood thinning medications to prevent the clotting of blood (anticoagulants), such as warfarin (Coumadin), because of an increased risk of bleeding. The increased risk is due to the fact that NSAIDs prevent the clotting of blood though by a different mechanism than anticoagulants. (They inhibit blood platelets which are important for the clotting of blood.) Piroxicam can increase blood levels of several drugs. Patients taking lithium can develop toxic blood lithium levels, and patients taking cyclosporine (Sandimmune) can develop kidney toxicity. Feldene Piroxicam may increase the toxic effects of methotrexate and may reduce the effectiveness of angiotensin converting enzyme (ACE) inhibitors .
Feldene side effects
Most patients benefit from Feldene piroxicam and other NSAIDs with few side effects. However, serious side effects can occur and generally tend to occur more frequently at higher doses. Therefore, it is advisable to use the lowest effective dose to minimize side effects. The most common side effects of Feldene piroxicam involve the gastrointestinal system. It can cause ulcerations, abdominal pain, cramping, nausea, gastritis, and even serious gastrointestinal bleeding and liver toxicity. Sometimes, stomach ulceration and bleeding can occur without any abdominal pain. Black tarry stools, weakness, and dizziness upon standing may be the only signs of internal bleeding. Rash, kidney impairment, ringing in the ears, and lightheadedness also can occur.
