Precautions
Taking an NSAID can increase your risk of life-threatening heart or circulation problems, including heart attack or stroke. This risk will increase the longer you use an NSAID. Do not use this medicine just before or after having heart bypass surgery (also called coronary artery bypass graft, or CABG).
NSAIDs can also increase your risk of serious effects on the stomach or intestines, including bleeding or perforation (forming of a hole). These conditions can be fatal and gastrointestinal effects can occur without warning at any time while you are taking an NSAID. Older adults may have an even greater risk of these serious gastrointestinal side effects.
Do not use this medication if you are allergic to diclofenac, or if you have a history of allergic reaction to aspirin or other NSAIDs.
Before taking diclofenac, tell your doctor if you are allergic to any drugs, or if you have:
- a history of heart attack, stroke, or blood clot;
- heart disease, congestive heart failure, high blood pressure;
- a history of stomach ulcers or bleeding;
- liver or kidney disease,
- asthma;
- polyps in your nose;
- a bleeding or blood clotting disorder; or
- if you smoke.
If you have any of these conditions, you may need a dose adjustment or special tests to safely take diclofenac.
FDA pregnancy category C. This medication may be harmful to an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant during treatment. Taking diclofenac during the last 3 months of pregnancy may harm the unborn baby. Do not take diclofenac during pregnancy unless your doctor has told you to.
Diclofenac can pass into breast milk and may harm a nursing baby. Do not use this medication without telling your doctor if you are breast-feeding a baby.
Do not give this medicine to a child without the advice of a doctor.
Do not use any other over-the-counter cold, allergy, or pain medication without first asking your doctor or pharmacist. Many medicines available over the counter contain aspirin or other medicines similar to diclofenac (such as ibuprofen, ketoprofen, or naproxen). If you take certain products together you may accidentally take too much of this type of medication. Read the label of any other medicine you are using to see if it contains aspirin, ibuprofen, ketoprofen, or naproxen.
Do not drink alcohol while taking diclofenac. Alcohol can increase the risk of stomach bleeding caused by diclofenac.
Avoid prolonged exposure to sunlight. Diclofenac may increase the sensitivity of the skin to sunlight. Use a sunscreen and wear protective clothing when exposure to the sun is unavoidable.
