Summary
Levetiracetam is a broad-spectrum antiepileptic drug that treats a wide range of seizures, including both generalized and focal seizures. It works by blocking SV2A, which reduces the release of excitatory neurotransmitters in the brain. Common side effects include fatigue and sedation, dizziness, and agitation. Levetiracetam can also cause neuropsychiatric effects like psychosis and has been linked to an increased risk of suicidal thoughts or behaviors.
