Diclofenac patch is a nonsteroidal anti-inflammatory drug (NSAID). It may cause an increased risk of serious and sometimes fatal heart and blood vessel problems (eg, a heart attack, a stroke, blood clots). The risk may be greater if you already have heart problems or if you take diclofenac patch for a long time. Do not use diclofenac patch right before or after bypass heart surgery.
Diclofenac patch may cause an increased risk of serious and sometimes fatal stomach ulcers and bleeding. Elderly patients may be at greater risk. This may occur without warning signs.
Diclofenac patch is used for:
Treating pain caused by minor strains, sprains, and bruises. It may also be used for other conditions as determined by your doctor.
Diclofenac patch is an NSAID. Exactly how it works is not known. It may block 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.
