Diclofenac is classified as a nonsteroidal anti-inflammatory drug (NSAID) and is indicated for the treatment of mild-to-moderate pain. It is used to alleviate the symptoms of arthritis (e.g., osteoarthritis or rheumatoid arthritis), including inflammation, swelling, stiffness, and joint pain.

This medication is also prescribed for ankylosing spondylitis, a type of arthritis that affects the spine’s joints, as well as for other painful conditions such as menstrual cramps. Diclofenac can also be used to treat acute migraine attacks, with or without aura, in adults. It does not prevent or reduce the frequency of migraine attacks.

Uses and Dosage

Diclofenac is available in various forms: tablets, liquid-filled capsules, hard gelatin capsules, extended-release tablets, delayed-release tablets, and packets of powder for solution to be taken orally.

Diclofenac liquid-filled capsules are typically taken four times daily, while diclofenac hard gelatin capsules are usually taken three times daily on an empty stomach. Diclofenac extended-release tablets are taken once daily, occasionally twice daily if necessary for pain control. Diclofenac tablets and delayed-release tablets are usually taken two, three, or four times a day.

Diclofenac solution is consumed without food as a one-time treatment to alleviate migraine headache pain.

If you’re instructed to take diclofenac regularly, do so at the same time(s) each day.

Take diclofenac precisely as directed, without altering the dosage or frequency unless advised by your doctor.

Different diclofenac products release the medication differently in the body and are not interchangeable. Only use the diclofenac product prescribed by your doctor, and refrain from switching to a different product unless instructed to do so.

Your doctor may modify your medication dosage during treatment based on your response. Keep your doctor informed about your experiences with diclofenac during treatment.

If you’re taking the powder for solution, mix it with water before consumption. Remove one packet from a row of three attached packets. Pour 2 to 4 tablespoons (1 to 2 ounces; 30 to 60 mL) of water into a cup, add the packet contents, mix thoroughly, and consume the entire mixture immediately. Dispose of the empty packet in a secure trash can, out of reach of children and pets.
