Key takeaways
Amitriptyline (formerly branded as Elavil) and topiramate (Topamax, Qudexy XR, and Trokendi XR) are both prescription medications, but they serve different primary purposes and belong to different drug classes. Amitriptyline, available as a generic, is a tricyclic antidepressant (TCA) primarily used to treat depression, though it is also used off-label for nerve pain and migraine prevention. It works by increasing levels of serotonin and norepinephrine in the brain. On the other hand, topiramate, also available in generic form, is an antiepileptic medication used to treat seizures and prevent migraines. Its exact mechanism for preventing migraines is unclear, but it helps control seizures by reducing nerve activity in the brain. Amitriptyline can cause side effects like sleepiness and weight gain, while topiramate can lead to weight loss and cognitive issues like trouble thinking clearly. Additionally, topiramate has a risk of causing kidney stones and serious eye problems, which are not common concerns with amitriptyline. Both medications have significant interactions with other drugs, but topiramate also requires careful monitoring for blood acid levels and potential birth defects if taken during pregnancy.

Summary of Elavil vs. Topamax
Summary for Tricyclic antidepressantPrescription onlyAmitriptyline is FDA approved to treat depression. But it isn't as commonly used today as other antidepressants because it can cause a lot of side effects, such as sleepiness and weight gain. In addition, amitriptyline has many interactions with other medications, including other antidepressants, sedatives, and antihistamines. But despite the side effects and interactions, amitriptyline is often used off label for nerve pain due to diabetes and migraine prevention. While its brand name Elavil is no longer available, amitriptyline is available as a generic medication.
Summary for AntiepilepticPrescription onlyTopiramate is a prescription medication that can be used alone or in combination with other medications to treat certain types of seizures. It can also be used to prevent migraines. It comes in immediate-release and extended-release tablets and capsules, as well as a liquid. Topiramate is typically taken by mouth once or twice daily, depending on what formulation you're using. Some forms of topiramate are available as lower-cost generic medications.
