Because cross-reactivity between aspirin and other NSAIDs has been reported in such aspirin-sensitive patients, Feldene is contraindicated in patients with this form of aspirin sensitivity NSAIDs, including piroxicam, can cause serious skin adverse reactions such as exfoliative dermatitis, Stevens-Johnson Syndrome (SJS), and toxic epidermal necrolysis (TEN), which can be fatal.
als Kombinationspräparat bei der Tuberkulose angewendet. Gastrointestinal bleeding has occurred. The safety and effectiveness of Feldene have not been established.Elderly patients, compared to younger patients, are at greater risk for NSAID-associated serious cardiovascular, gastrointestinal, and/or renal adverse reactions. …
Only one in five patients who develop a serious upper GI adverse event on NSAID therapy is symptomatic. These events can occur at any time during use and without warning symptoms. This may be due to occult or gross blood loss, fluid retention, or an incompletely described effect on erythropoiesis. Carefully consider the potential benefits and risks of Feldene and other treatment options before deciding to use Feldene. Patients should be informed about the symptoms of serious CV events and the steps to take if they occur.There is no consistent evidence that concurrent use of aspirin mitigates the increased risk of serious CV thrombotic events associated with NSAID use. Small studies in women treated with NSAIDs have also shown a reversible delay in ovulation. If a patient treated with Feldene has any signs or symptoms of anemia, monitor hemoglobin or hematocrit.NSAIDs, including Feldene, may increase the risk of bleeding events. It exhibits a weakly acidic 4-hydroxy proton (pKa 5.1) and a weakly basic pyridyl nitrogen (pKa 1.8).The inactive ingredients in Feldene include: Blue 1, Red 3, lactose, magnesium stearate, sodium lauryl sulfate, starch.Piroxicam has analgesic, anti-inflammatory, and antipyretic properties.The mechanism of action of Feldene, like that of other NSAIDs, is not completely understood but involves inhibition of cyclooxygenase (COX-1 and COX-2).Piroxicam is a potent inhibitor of prostaglandin (PG) synthesis in vitro. Most postmarketing reports of fatal GI events occurred in elderly or debilitated patients. Physicians and patients should remain alert for the development of such events, throughout the entire treatment course, even in the absence of previous CV symptoms. Feldene is indicated for symptomatic relief of osteoarthritis, rheumatoid arthritis or ankylosing spondylitis. Patients at greatest risk of this reaction are those with impaired renal function, dehydration, hypovolemia, heart failure, liver dysfunction, those taking diuretics and ACE inhibitors or ARBs, and the elderly.

Piroxicam appeared in breast milk at approximately 1% to 3% of the maternal concentration.
However, even short-term NSAID therapy is not without risk.Elevations of alanine aminotransferase (ALT) or aspartate aminotransferase (AST) (three or more times the upper limit of normal [ULN]) have been reported in approximately 1% of NSAID-treated patients in clinical trials.
