Key takeaways
Sumatriptan (Imitrex) and levetiracetam (Keppra) are both prescription medications, but they treat different conditions. Sumatriptan is used to treat migraines in adults and belongs to the triptan class. It works by tightening blood vessels and reducing inflammation in the brain. You take it as needed for migraines, with a maximum of two doses in 24 hours. Common side effects include tingling, feeling too warm or cold, and fatigue. On the other hand, evetiracetam is an antiepileptic medication used to treat various types of seizures. It is taken daily, either once or twice, depending on the formulation. Unlike sumatriptan, levetiracetam can cause sleepiness, weakness, and mood changes, especially in children. Both medications are available in generic forms, making them more affordable. However, sumatriptan has more specific drug interactions and is not recommended for people with certain heart conditions, while levetiracetam has fewer interactions but can affect mood and behavior.
