Check with your doctor if you have used this medicine and have not had good relief. Also, check with your doctor if your migraine headaches are worse, or if they are occurring more often, than before you started using this medicine.

This medicine may increase your risk of having a heart attack or stroke. This is more likely to occur if you or a family member already has a heart disease, if you have diabetes, high blood pressure, high cholesterol, if you smoke, if you are male and over 40 years of age, or if you are female and have gone through menopause.

Although this is rare, it may occur more often in patients who are allergic to aspirin or to any of the nonsteroidal anti-inflammatory drugs (NSAIDs). Anaphylaxis requires immediate medical attention. The most serious signs of this reaction are very fast or irregular breathing, gasping for breath, wheezing, or fainting. Other signs may include changes in the color of the skin of the face, very fast but irregular heartbeat or pulse, hive-like swellings on the skin, and puffiness or swellings of the eyelids or around the eyes. If these effects occur, get emergency help at once.

Using too much of this medicine or any other migraine medicines (e.g., ergotamine, triptans, opioids, or a combination treatment for 10 or more days per month) may worsen your headache. Talk to your doctor about this risk. It may also be helpful to note of how often your migraine attacks occur and how much medicines you use.
Check with your doctor immediately if blurred vision, difficulty in reading, or any other change in vision occurs during or after your treatment. Your eyes may need to be checked by an ophthalmologist (eye doctor).
Drinking alcoholic beverages can make headaches worse or cause new headaches to occur. People who suffer from severe headaches should probably avoid alcoholic beverages, especially during a headache.
