What is Cataflam?

Cataflam (diclofenac potassium) is a nonsteroidal anti-inflammatory drug (NSAID). Diclofenac works by reducing substances in the body that cause pain and inflammation.

Cataflam is used to treat mild to moderate pain, or signs and symptoms of osteoarthritis or rheumatoid arthritis.

Cataflam is also used to treat menstrual cramps.

Do not use Cataflam just before or after heart bypass surgery (coronary artery bypass graft, or CABG).

How should I take Cataflam?

Take Cataflam exactly as directed on the label, or as prescribed by your doctor. Your doctor may occasionally change your dose to make sure you get the best results. Do not take this medicine in larger amounts or for longer than recommended. Use the lowest dose that is effective in treating your condition.

For treatment of pain or primary dysmenorrhea the recommended dosage of Cataflam is 50 mg three times daily. In some patients an initial dose of 100 mg of Cataflam, followed by 50 mg doses, may provide better relief.

For the relief of osteoarthritis the recommended dosage of Cataflam is 100-150 mg/day in divided doses, i.e. 50 mg two or three times a day.

For the relief of rheumatoid arthritis the recommended dosage is 150-200 mg/day in divided doses, i.e. 50 mg three or four times a day.

Different formulations of diclofenac, Voltaren (diclofenac sodium tablets) and Cataflam (diclofenac potassium immediate-release tablets) are not necessarily equivalent in strength even if the milligram strength is the same.

If you use Cataflam long-term, you may need frequent medical tests.

Store at room temperature away from moisture and heat. Keep the bottle tightly closed when not in use.

Read all patient information, medication guides, and instruction sheets provided to you. Ask your doctor or pharmacist if you have any questions.

What happens if I miss a dose?

Take the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not take extra medicine to make up the missed dose.
