What is the administration route for Olanzapine for acute agitation?

  1. Orally

  2. IM injection

  3. Topically

  4. Nasally

The correct answer is: IM injection

Olanzapine for acute agitation is typically administered through intramuscular injection (IM injection). This is because an IM injection ensures a faster onset of its effects compared to other routes, such as orally, topically, or nasally. These other options may be considered for maintenance treatment after the acute agitation is controlled, but for immediate relief of symptoms, an IM injection is the preferred administration route. It allows the medication to be quickly absorbed into the bloodstream, leading to a more rapid and effective response.
