intramuscular injection

An intramuscular injection involves administering medication directly into a muscle using a needle and syringe. This method allows the medicine to be absorbed quickly into the bloodstream because muscles have a good blood supply. Healthcare providers typically use this approach for vaccines, hormone therapies, or antibiotics when a slower or more controlled release isn’t needed. The injection is usually given in large muscles like the upper arm, thigh, or buttocks. Proper technique and sterilization are essential to prevent infection and ensure effective delivery of the medication.
