Are there any risks in taking Topamax (topiramate)?

Risks in taking Topamax (topiramate) include experiencing side effects, such as blurred or double vision, drowsiness, dizziness and trouble thinking or speaking. Until you know how you react to the drug, it is best not to drive or operate heavy machinery while using it. Sometimes Topamax makes you stop sweating, which can raise your body temperature, making you more likely to become overheated, dizzy, faint or succumb to heat stroke. This drug can also cause mood swings or behavior changes, which can lead to depression, agitation, irritability and suicidal thoughts or actions. You and your family should be vigilant about watching for any disturbing mental changes. Developing kidney stones is an additional risk of taking Topamax. Drinking six to eight glasses of water each day may help prevent this. If your child takes this drug, it may slow growth.Your child may also develop hyperammonemic encephalopathy, which is a serious condition. If your child experiences odd drowsiness, lethargy, dullness, sluggishness, anxiety or depression, unusual or vivid dreams and nightmares, or vomiting, call your doctor immediately. Use of this drug may amplify the effects of alcohol or central nervous system depressants, such as sleep and pain medicines and antihistamines used for colds, hay fever, and allergies, by making you drowsier and less alert. On the other hand, birth control drugs that contain estrogen may become less effective while you are on this medication.
