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. These events can occur without any warning and can lead to death.
Be sure to tell your doctor if you have or have ever had any of the following:
- Heart disease or a heart attack
- A stroke
- High blood pressure (hypertension)
- High cholesterol.
You should also talk with your healthcare provider prior to taking diclofenac potassium if you have:
- Congestive heart failure
- Liver disease or failure
- Kidney disease or failure
- Bleeding problems (or if you are taking a medicine that decreases the ability of your blood to clot)
- Stomach ulcers, stomach bleeding, or a history of either condition
- Any allergies to medicines, including aspirin or other NSAID pain medicines.
Let your healthcare provider know if you:
- Are pregnant or thinking about becoming pregnant (see Diclofenac and Pregnancy)
- Are breastfeeding (see Diclofenac and Breastfeeding)
- Drink alcohol frequently
- Have recently had heart surgery.
Also, tell your healthcare provider about all other medicines you may be currently taking, including prescription and non-prescription medicines, vitamins, and herbal supplements.
