Head-to-head comparisons of medication uses, side effects, warnings, and more.
Sumatriptan (Imitrex) and topiramate (Topamax) are both used to manage migraines, but they work differently and have different uses. Sumatriptan is a triptan that treats migraines by tightening blood vessels and reducing inflammation. It's taken as needed when a migraine starts and can be taken again after 2 hours if needed, but not more than twice in 24 hours. Topiramate, on the other hand, is an antiepileptic that prevents migraines and treats seizures. It's taken daily, either once or twice, depending on the form. Sumatriptan is available as a lower-cost generic, while topiramate also comes in generic forms and various formulations, including tablets, capsules, and a liquid. Sumatriptan can cause heart problems and serotonin syndrome, while topiramate can lead to kidney stones, vision problems, and high blood acid levels. Both medications interact with other drugs, so it's important to discuss all your medications with your prescriber.
Sumatriptan (Imitrex) is used to treat migraines with or without aura in adults. The medication is typically taken as a single dose for your migraine. But, it's possible that you can take it again 2 hours after the first dose if your migraine doesn't go away. Side effects of sumatriptan (Imitrex) include tingling or numbness of fingers or toes, feeling too warm or too cold, and fatigue. It can interact with antidepressants and other similar migraine medications. Sumatriptan (Imitrex) is available as a lower-cost generic tablet.
Topiramate 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.
Please note: These are common side effects reported by children and adults who took immediate-release topiramate. Frequency of side effects can differ based on your age, as well as the dose and formulation of topiramate you're taking.
