Q: What is the FDA approval status of Zyprexa?

FDA Approval and Indications Zyprexa (olanzapine) was first approved by the FDA in 1996. It is currently indicated for the treatment of schizophrenia and bipolar I disorder, including acute manic or mixed episodes and maintenance treatment. It is also approved for use in combination with fluoxetine for treatment-resistant depression and depressive episodes associated with bipolar I disorder. Boxed Warning The FDA has issued a boxed warning for Zyprexa regarding its use in elderly patients with dementia-related psychosis. Clinical studies have shown that elderly patients with dementia-related psychosis treated with antipsychotic drugs are at an increased risk of death. Zyprexa is not approved for the treatment of patients with dementia-related psychosis. REMS Program The long-acting injectable formulation, Zyprexa Relprevv, is subject to a Risk Evaluation and Mitigation Strategy (REMS). This regulatory program is required due to the risk of post-injection delirium sedation syndrome (PDSS), a serious condition that can occur after receiving the injection. Under this program, the medication must be administered in a registered healthcare facility with ready access to emergency response services, and patients must be monitored for at least three hours after each dose. Safety Communications Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS): The FDA has issued warnings that olanzapine can cause DRESS, a rare but serious and potentially fatal systemic reaction that may include a rash, fever, and organ inflammation. Opioid Interactions: The FDA warns that combining antipsychotics like Zyprexa with opioid medications can result in profound sedation, respiratory depression, coma, and death.
