Do not use any other over-the-counter cold, allergy, or pain medication without first asking your doctor or pharmacist. Many medicines available over the counter contain aspirin or other medicines similar to Voltaren (such as ibuprofen, ketoprofen, or naproxen). If you take certain products together you may accidentally take too much of this type of medication. Read the label of any other medicine you are using to see if it contains aspirin, ibuprofen, ketoprofen, or naproxen.

Do not use this medication if you are allergic to Voltaren, or if you have a history of allergic reaction to aspirin or other NSAIDs.

Do not drink alcohol while taking Voltaren. Alcohol can increase the risk of stomach bleeding caused by Voltaren.

Avoid prolonged exposure to sunlight. Voltaren may increase the sensitivity of the skin to sunlight. Use a sunscreen and wear protective clothing when exposure to the sun is unavoidable.

Voltaren can increase your risk of life-threatening heart or circulation problems, including heart attack or stroke. This risk will increase the longer you use Voltaren. Do not use this medicine just before or after having heart bypass surgery (also called coronary artery bypass graft, or CABG).

This medicine can also increase your risk of serious effects on the stomach or intestines, including bleeding or perforation (forming of a hole). These conditions can be fatal and gastrointestinal effects can occur without warning at any time while you are taking Voltaren. Older adults may have an even greater risk of these serious gastrointestinal side effects. Call your doctor at once if you have symptoms of bleeding in your stomach or intestines. This includes black, bloody, or tarry stools, or coughing up blood or vomit that looks like coffee grounds.

If you have any of these other conditions, you may need a dose adjustment or special tests to safely take Voltaren:

• a history of heart attack, stroke, or blood clot;
• heart disease, congestive heart failure, high blood pressure;
• a history of stomach ulcers or bleeding;
• asthma;
• polyps in your nose;
• a bleeding or blood clotting disorder; or
• if you smoke.

• liver or kidney disease,
