What Is Feldene and Feldene-D Used For?

Feldene contains piroxicam, which belongs to a group of medicines called Non-Steroidal Anti-inflammatory Drugs (NSAIDs). These medicines help reduce pain and inflammation in your body.

Primary Uses

Feldene is used to treat symptoms of rheumatoid arthritis, osteoarthritis, and ankylosing spondylitis (a chronic inflammatory condition that mainly affects the spine but can affect other areas too).

How It Works

Feldene works by relieving pain and reducing inflammation (heat, throbbing, swelling, and redness) in affected joints and tissues.

Good to know: While Feldene can effectively relieve your pain and inflammation symptoms, it will not cure your underlying condition.

How to Take Feldene and Feldene-D

Take Feldene exactly as your doctor has prescribed. It’s important to follow the dosage instructions carefully for the best results.

Dosage Instructions

The usual dose is between 10 mg and 20 mg taken once daily. Take it at the same time each day, either morning or evening. It’s best to take Feldene immediately after food to avoid stomach upset. For capsules, swallow them whole with water. For dispersible tablets (Feldene-D), dissolve the tablet in a glass of water and drink it right away.

What If You Miss a Dose?

If it’s almost time for your next dose (within 2-3 hours), skip the missed dose and take your next dose at the regular time. Don’t take a double dose to make up for the one you missed.

Important: Never take a double dose to make up for a missed dose, as this can increase your risk of side effects.
