Studies show that the success rates of intended intramuscular injections can vary widely, from 32% to 52%, with many injections inadvertently ending up in subcutaneous fat [1.7.2]. Knowing where do they inject in the buttocks correctly is critical for medication effectiveness and patient safety.

The gluteal muscles can safely accommodate up to 5ml of medication in a single injection, far more than smaller muscles like the deltoid (upper arm). This capacity is a primary reason behind the common question: 'Why do they inject you in the bum?'

Historically, injections were often administered in the buttocks' dorsogluteal site, but due to risks like sciatic nerve injury and poor medication absorption, modern medical practice has largely abandoned this location. The shift towards safer and more effective injection sites is an evidence-based change aimed at prioritizing patient safety and therapeutic efficacy.
