Are there any serious health risks associated with diclofenac use?
People who take NSAIDs (other than aspirin) such as diclofenac may have a higher risk of having a heart attack or a stroke than people who do not take these medications. These events may happen without warning and may cause death, and this risk may be higher for people who take NSAIDs for a long time. Also, NSAIDs such as diclofenac may cause ulcers, bleeding, or holes in the stomach or intestine. These problems may develop at any time during treatment, may happen without warning symptoms, and may cause death.
