Common use
Feldene is primarily prescribed for the symptomatic treatment of osteoarthritis and rheumatoid arthritis in adults. It is used to manage the pain, inflammation, and stiffness associated with these conditions. Some clinicians may also prescribe it off-label for acute musculoskeletal disorders, though this is not its primary indication. The medication is typically used as part of a comprehensive treatment plan that may include physical therapy, weight management, and other therapeutic interventions.
Dosage and direction
The recommended initial dosage for osteoarthritis and rheumatoid arthritis is 20 mg once daily. This may be administered as a single dose or divided into two equal doses of 10 mg. For patients at increased risk of adverse reactions, a lower initial dose of 10 mg daily may be appropriate. The medication should be taken with food or milk to minimize gastrointestinal discomfort. Dosage should be individualized based on therapeutic response and tolerability, with the lowest effective dose used for the shortest duration possible. Maximum recommended daily dose is 20 mg.
Precautions
Patients should be monitored for signs of gastrointestinal bleeding or ulceration, particularly those with a history of peptic ulcer disease. Renal function should be assessed periodically, especially in elderly patients or those with pre-existing renal impairment. Use with caution in patients with hypertension, heart failure, or other cardiovascular risk factors. Hepatic function should be monitored during prolonged therapy. Patients should be advised to avoid alcohol consumption during treatment, as it may increase the risk of gastrointestinal bleeding. Caution is advised when engaging in activities requiring alertness until response to the medication is known.
Contraindications
Feldene is contraindicated in patients with known hypersensitivity to piroxicam, aspirin, or other NSAIDs. It should not be used in patients who have experienced asthma, urticaria, or allergic-type reactions after taking aspirin or other NSAIDs. Contraindicated in the setting of coronary artery bypass graft (CABG) surgery. Should not be used in patients with active peptic ulcer disease or gastrointestinal bleeding. Avoid use in patients with severe heart failure, advanced renal disease, or severe hepatic impairment. Not recommended during the third trimester of pregnancy.
Possible side effects
Common side effects (≥1%) include dyspepsia, nausea, abdominal pain, diarrhea, constipation, flatulence, dizziness, headache, and peripheral edema. Less frequent adverse reactions may include elevated liver enzymes, pruritus, rash, tinnitus, and fluid retention. Serious side effects requiring immediate medical attention include gastrointestinal bleeding or perforation, hepatotoxicity, renal impairment, severe skin reactions, and cardiovascular thrombotic events. Patients should be instructed to report any signs of bleeding, unusual weight gain, or changes in urinary output.
Drug interactions
Feldene may increase the risk of bleeding when used with anticoagulants such as warfarin. Concurrent use with other NSAIDs or aspirin may increase the risk of gastrointestinal adverse effects. May reduce the antihypertensive effect of ACE inhibitors, angiotensin II receptor blockers, and beta-blockers. Can increase lithium levels and risk of lithium toxicity. May enhance the nephrotoxic potential of cyclosporine. Diuretics may have reduced effectiveness when co-administered with piroxicam. Caution advised with methotrexate due to potential for increased toxicity.
Missed dose
If a dose is missed, it should be taken as soon as remembered unless it is almost time for the next scheduled dose. In that case, skip the missed dose and resume the regular dosing schedule. Do not double the dose to make up for a missed one. Patients should be advised to maintain a consistent dosing schedule to ensure optimal therapeutic effects.
Overdose
Symptoms of overdose may include lethargy, drowsiness, nausea, vomiting, epigastric pain, gastrointestinal bleeding, coma, or acute renal failure. In case of suspected overdose, seek immediate medical attention. Management is supportive and symptomatic. There is no specific antidote. Gastric lavage or activated charcoal may be considered if presented soon after ingestion. Hemodialysis is not effective due to high protein binding.
Storage
Store at room temperature (15-30°C or 59-86°F) in a dry place protected from light and moisture. Keep in the original container with the lid tightly closed. Do not store in bathroom cabinets where moisture may accumulate. Keep out of reach of children and pets. Do not use after the expiration date printed on the packaging. Properly discard any unused medication after treatment completion.

Reviews
Clinical studies have demonstrated Feldene’s efficacy in managing arthritic symptoms, with many patients reporting significant improvement in pain scores and functional capacity. The once-daily dosing regimen is frequently cited as a significant advantage for long-term management. Some patients report gastrointestinal discomfort, particularly during initial treatment, which often subsides with continued use. Healthcare providers generally consider it an effective option for appropriate patients when used according to prescribing guidelines. Regular monitoring is emphasized to ensure continued safety and efficacy throughout treatment.
