====== Levetiracetam and Risk of Angioedema in patients with Seizure Disorder ======

<WRAP box justify round>

**Objective:** To assess the risk between exposure to Keppra (levetiracetam) and angioedema.

**Rationale:** The Food and Drug Administration (FDA) has [[http://www.fda.gov/Drugs/GuidanceComplianceRegulatoryInformation/Surveillance/AdverseDrugEffects/ucm491645.htm|recently announced]] that they are evaluating the need for regulatory action regarding a potential association between exposure to the anti-seizure drug Keppra and angioedema. OHDSI seeks to support evidence generation for questions of importance to FDA and other stakeholders seeking to protect and promote the public's health.
