What is Voltaren?
Voltaren (diclofenac) is a nonsteroidal anti-inflammatory drug (NSAID). Diclofenac works by reducing substances in the body that cause pain and inflammation.
Voltaren may also be used for purposes not listed in this medication guide.
You should not use Voltaren if you have a history of allergic reaction to aspirin or NSAIDs (non-steroidal anti-inflammatory drugs).
Voltaren may also cause stomach or intestinal bleeding, which can be fatal. These conditions can occur without warning while you are using Voltaren, especially in older adults.
Before taking this medicine
Voltaren can increase your risk of fatal heart attack or stroke, especially if you use it long term or take high doses, or if you have heart disease. Even people without heart disease or risk factors could have a stroke or heart attack while taking this medicine.
Do not use Voltaren just before or after heart bypass surgery (coronary artery bypass graft, or CABG).
You should not use Voltaren if you are allergic to diclofenac, or if you have ever had an asthma attack or severe allergic reaction after taking aspirin or an NSAID.
