the three most commonly used sites for intramuscular injections are
Intramuscular injection Possible sites for IM injection include: deltoid, dorsogluteal, rectus femoris, vastus lateralis and ventrogluteal muscles.[2] Sites that are bruised, tender, red, swollen, inflamed or scarred are avoided.[1]
Triamcinolone acetonide Triamcinolone acetonide as an intra-articular injectable has been used to treat a variety of musculoskeletal conditions. When applied as a topical ointment, applied to the skin, it is used to mitigate blistering from poison ivy, oak, and sumac,[citation needed]. When combined with Nystatin, it is used to treat skin infections with discomfort from fungus, though it should not be used on the eyes, mouth, or genital area.[5] It provides relatively immediate relief and is used before using oral prednisone. Oral and dental paste preparations are used for treating aphthous ulcers.
