Diclofenac Gel

Diclofenac Gel is used for treating pain in certain joints (e.g., in the knees or hands) caused by osteoarthritis. It may also be used for other conditions as determined by your doctor.

Diclofenac Gel is an NSAID. It may work by blocking certain substances in the body that are linked to inflammation. NSAIDs treat the symptoms of pain and inflammation. They do not treat the disease that causes those symptoms.

Do not use Diclofenac Gel if:

• you are allergic to any ingredient in Diclofenac Gel;
• you have had a severe allergic reaction (e.g., severe rash, hives, trouble breathing, growths in the nose, dizziness) to aspirin or an NSAID (e.g., celecoxib, ibuprofen);
• you have recently had or will be having bypass heart surgery;
• you have severe kidney problems;
• you are in the last 3 months of pregnancy.

• Diclofenac Gel may cause dizziness. This effect may be worse if you take it with alcohol or certain medicines. Use Diclofenac Gel with caution. Do not drive or perform other possibly unsafe tasks until you know how you react to it.
• Diclofenac Gel is for external use only. Do not get it in your eyes, nose, or mouth. If you get it in any of these areas, rinse at once with cool water.
• Serious stomach ulcers or bleeding can occur with the use of Diclofenac Gel. Using it in high doses, for a long time, smoking, or drinking alcohol increases the risk of these side effects. If you have severe stomach or back pain; black, tarry stools; vomit that looks like blood or coffee grounds; or unusual weight gain or swelling, contact your doctor or emergency room right away.
• Do not use more than the recommended dose or use for longer than prescribed without checking with your doctor.
• Diclofenac Gel is an NSAID. Before you start any new medicine, check the label to see if it has an NSAID (e.g., ibuprofen) in it too. If it does or if you are not sure, check with your doctor or pharmacist.
• Do not take aspirin while you are using Diclofenac Gel unless your doctor tells you to.
• Do not use sunscreens, lotions, insect repellants, or other topical medicines on the treated area.
• Do not expose the treated area to the sun, sunlamps, or tanning booths.
• Diclofenac Gel may cause harm if it is swallowed. If you may have taken it by mouth, contact your poison control center or emergency room right away.
• Lab tests, including kidney function, complete blood counts, and blood pressure, may be performed while you use Diclofenac Gel. These tests may be used to monitor your condition or check for side effects. Be sure to keep all doctor and lab appointments.
• Pregnancy and breast-feeding: Diclofenac Gel may cause harm to the fetus. Do not use it during the last 3 months of pregnancy. If you think you may be pregnant, contact your doctor. You will need to discuss the benefits and risks of using Diclofenac Gel while you are pregnant. It is not known if Diclofenac Gel is found in breast milk after topical use. Do not breast-feed while taking Diclofenac Gel.

Check with your doctor if any of these most common side effects persist or become bothersome:

• mild irritation at the application site.

• severe allergic reactions (rash; hives; itching; trouble breathing; tightness in the chest; swelling of the mouth, face, lips, or tongue); bloody or black, tarry stools; change in the amount of urine produced; chest pain; confusion; dark urine; depression; fainting; fast or irregular heartbeat; fever, chills, or persistent sore throat; mental or mood changes; numbness of an arm or leg; one-sided weakness; red, swollen, blistered, or peeling skin; ringing in the ears; seizures; severe headache or dizziness; severe or persistent irritation at the application site; severe or persistent stomach pain or nausea; severe vomiting; shortness of breath; sudden or unexplained weight gain; swelling of hands, legs, or feet; unusual bruising or bleeding; unusual joint or muscle pain; unusual tiredness or weakness; vision or speech changes; vomit that looks like coffee grounds; yellowing of the skin or eyes.

Diclofenac Gel is to be used only by the patient for whom it is prescribed. Do not share it with other people.

If your symptoms do not improve or if they become worse, check with your doctor.
