OKSAMEN tablet and OKSAMEN-L for injection should not be used in patients with aspirin and other NSAID-induced asthma, rhinitis, urticaria and angioedema. Patients on oral antidiabetic or anticoagulant therapy should be closely monitored; if monitoring is not possible, they should not be used concomitantly.BUN, serum creatinine, weight gain and development of peripheral edema should be closely monitored in patients with conditions that may increase the risk of renal failure such as the elderly, patients with diabetic nephropathy, severe hepatic failure, congestive heart failure, hypovolemia, patients with a history of renal disease and those receiving diuretics or nephrotic agents.

Drug Interactions

Tenoxicam, at therapeutic doses, has no pharmacokinetic interaction with antacids, cimetidine, oral antidiabetics and oral anticoagulant agents; however, it can increase the effects of anticoagulant agents such as coumarine.
