Why is this medication prescribed?
Diclofenac capsules (Zipsor, Zorvolex) and tablets (Cataflam) are used to relieve mild to moderate pain. Diclofenac extended-release tablets (Voltaren XR), tablets (Cataflam), and delayed release tablets (available generically) are used to relieve pain, tenderness, swelling, and stiffness caused by osteoarthritis (arthritis caused by a breakdown of the lining of the joints), and rheumatoid arthritis (arthritis caused by swelling of the lining of the joints). Diclofenac extended-release tablets and delayed-release tablets are also used to treat ankylosing spondylitis (arthritis that mainly affects the spine). Diclofenac tablets (Cataflam) are also used to treat painful menstrual periods. Diclofenac solution (Cambia) is used to treat migraine headaches in adults, but cannot be used to prevent migraines or to treat other types of headaches. Diclofenac is in a class of medications called NSAIDs. It works by stopping the body's production of a substance that causes pain, fever, and inflammation.
How should this medicine be used?
Diclofenac comes as a tablet, and liquid-filled capsule, a hard gelatin capsule, an extended-release (long-acting) tablet, a delayed-release (releases medication in the intestine) tablet, and as packets of powder for solution (to be mixed with water) and take by mouth. Diclofenac liquid-filled capsules are usually taken 4 times a day and diclofenac hard gelatin capsules are usually taken three times a day on an empty stomach. Diclofenac extended-release tablets are usually taken once a day, and in rare cases are taken twice a day, if needed to control pain. Diclofenac tablets and diclofenac delayed-release tablets are usually taken 2, 3, or 4 times a day. Diclofenac solution is taken without food as a one dose treatment to relieve the pain of migraine headaches. If you were told to take diclofenac on a regular basis, take it at around the same time(s) every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take diclofenac exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Different diclofenac products release the medication differently in your body and cannot be used interchangeably. Only take the diclofenac product prescribed by your doctor and do not switch to a different diclofenac product unless your doctor says that you should.
Your doctor may adjust the dose of your medication during your treatment depending on your response to the medication. Talk to your doctor about how you are feeling during your treatment with diclofenac.
If you are taking the powder for solution, you will need to mix it with water before you take it. To mix the medication, first remove one packet from a row of three attached packets. Place 2 to 4 tablespoons (1 to 2 ounces; 30 to 60 mL) of water in a cup. Add the contents of the packet and mix well. Drink the entire mixture right away. Throw away the empty packet in a trash can that is out of the reach of children and pets.
