The U.S. Food and Drug Administration (FDA) warns that people using NSAIDs, including diclofenac potassium, may have a higher risk of having a heart attack or stroke than those people who do not take NSAIDs. This warning does not apply to those who take aspirin. This risk may be higher in people who have been taking NSAIDs for a long time.
