What should I know about Topamax (topiramate) before taking it?

Before taking Topamax, it is important that you know this medication may be risky for people with kidney stones or other kidney problems, liver disease or glaucoma. These conditions may be worsened by Topamax. If you have emphysema, asthma or another respiratory condition, inform your doctor before taking Topamax. You should also be aware if you're allergic to the active ingredient, topiramate, and talk to your doctor about other medications you're taking to make sure there won't be any negative interactions.
Also, know that Topamax can make you sleepy or dizzy, and it may make you stop sweating, so it may become harder for your body to maintain a comfortable temperature. Topamax can worsen depression, so if you've struggled with depression inform your doctor of this beforehand. If you're on medication to prevent pregnancy, know that Topamax can make birth control work less effectively. If you're already pregnant or breastfeeding, you'll want to notify your doctor.
Also tell your doctor if you notice any vision problems, such as blurred or double vision, while taking Topamax.
