Levetiracetam, marketed under the trade name Keppra among others, is a medication used to treat epilepsy. It is used for partial onset, myoclonic, or tonic-clonic seizures. It is taken by mouth as an immediate or extended release formulation or by injection into a vein.

Common side effects include sleepiness, dizziness, feeling tired, and aggression. Severe side effects may include psychosis, suicide, and allergic reactions such as Stevens–Johnson syndrome and anaphylaxis. It is unclear if use is safe during pregnancy but appears to be safe for use when breastfeeding. It is the S-enantiomer of etiracetam. How it works is not clear.
