What is the most important information I should know about diclofenac (Voltaren XR)?

This medicine may cause life-threatening heart or circulation problems such as heart attack or stroke, especially if you use it long term. Do not use diclofenac just before or after heart bypass surgery (coronary artery bypass graft, or CABG).

Get emergency medical help if you have chest pain, weakness, shortness of breath, slurred speech, or problems with vision or balance.

This medicine may also cause serious effects on the stomach or intestines, including bleeding or perforation (forming of a hole). These conditions can be fatal and can occur without warning while you are taking diclofenac, especially in older adults.

Ask a doctor or pharmacist before using any cold, allergy, or other pain medicine. Medicines similar to diclofenac are contained in many combination medicines. Taking certain products together can cause you to get too much of this type of medication. Check the label to see if a medicine contains aspirin, ibuprofen, ketoprofen, or naproxen.

Avoid drinking alcohol. It may increase your risk of stomach bleeding.
