While some common side effects are associated with Topamax, it is essential to remember that your doctor prescribed this medication because they believe its ability to suppress your seizures outweighs any adverse side effects it may cause.

As with all prescription medications, be sure to inform the prescribing doctor about any medical conditions you have been previously diagnosed with and any medication/ supplements you are currently taking before starting treatment with Topamax.
Drug interactions involving Topamax can often be severe, and it is important to consider potential drug interactions before taking this medication. Topamax can interact with antacids, blood thinners, birth control medications, and antidepressants. It is also important to avoid taking Topamax with alcohol or other medicines containing topiramate. Taking any of these combined with Topamax can increase the risk of side effects such as vision changes, drowsiness, confusion, and difficulty concentrating. It may even cause more serious problems, such as an increased risk of seizures or depression.
In addition, let your doctor know if you are pregnant or plan on becoming pregnant before starting treatment with this medication.
