If you're accustomed to treating migraines one at a time, changing to a daily migraine prevention medication like TOPAMAX is a different experience. It's a big step, but remember that TOPAMAX has been prescribed to more than 4 million people worldwide.*
As with many migraine prevention medications, it may take 2 to 3 months to achieve the full benefit, but for some patients the effects of TOPAMAX may be experienced at 1 month.

*Since 1995, regardless of condition.

IMPORTANT SAFETY INFORMATION

Serious risks associated with TOPAMAX include lowered bicarbonate levels in the blood resulting in an increase in the acidity of the blood (metabolic acidosis). Symptoms could include hyperventilation (rapid, deep breathing), tiredness, loss of appetite, irregular heartbeat or changes in the level of alertness. Call your doctor immediately if you get these symptoms. Your doctor may want to do simple blood tests. Chronic, untreated metabolic acidosis may increase the risk for kidney stones or bone disease.

Other serious risks include decreased sweating, increased body temperature, kidney stones, sleepiness, dizziness, confusion, difficulty concentrating, and increased eye pressure (glaucoma). Call your doctor immediately if you have any decrease in vision or eye pain. These problems can lead to blindness if not treated right away.

More common side effects are tingling in arms and legs, loss of appetite, tiredness, nausea, diarrhea, taste change and weight loss.

Tell your doctor about other medications you take. Please see full U.S. Prescribing Information.
