What Does IM Stand For?

IM stands for Intramuscular

IM, or Intramuscular, refers to a method of delivering medication or vaccine directly into the muscle tissue. This route allows for rapid absorption into the bloodstream and is commonly used for injections requiring a quicker onset of action compared to other methods, such as subcutaneous or oral administration. Intramuscular injections are typically performed in larger muscles, such as the deltoid, thigh, or buttock, and are widely utilized in healthcare for vaccinations, hormone therapies, and other treatments.
