👩🏽⚕️ Frequently Asked Questions (FAQs)
💬 Is Haloperidol considered a last-resort medication for certain conditions?
Haloperidol is a potent, established first-generation (typical) antipsychotic used to manage schizophrenia and severe psychosis. In clinical settings, it is often utilized to rapidly manage acute agitation or violent behavior, helping to safely stabilize patients.
