what is the maximum intramuscular injection amount for an adult?
If a series of injections are to be given, the injection site is usually varied or rotated. Generally only limited injection volumes can be given by intramuscular injection: 2 ml in the deltoid and thigh muscles, and up to 5 ml in the gluteus maximus. The point of injection should be as far as possible from major nerves and blood vessels to avoid neural damage and accidental intravenous administration.
