Triamcinolone acetonide is a synthetic corticosteroid used to treat various skin conditions, and to relieve the discomfort of mouth sores. In nasal spray form, it is used to treat allergic rhinitis. It is a more potent derivative of triamcinolone, and is about eight times as potent as prednisone.

It is also known under the brand names Kenalog (topical) and Volon A as an injection, to treat allergies, arthritis, eye diseases, intestinal problems, and skin diseases. There are possible risks from an injection. It has been known to cause fat and muscle loss at an injection site, leaving a large divot bone deep.

Medical use

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 and discomfort from fungus, though it should not be used on the eyes, mouth, or genital area. It provides relatively immediate relief and is used before using oral prednisone. Oral and dental paste preparations are used for treating aphthous ulcers.

As an intravitreal injection, triamcinolone acetonide has been used to treat various eye diseases and has been found useful in reducing macular edema. Drug trials have found it to be as efficient as anti-VEGF drugs in eyes with artificial lenses over a two-year period.

Uncommonly, intramuscular injection of triamcinolone acetonide may be indicated for the control of severe or incapacitating allergic states for which conventional treatments have failed, such as asthma, atopic dermatitis, contact dermatitis, perennial or seasonal allergic rhinitis, serum sickness, and transfusion and drug hypersensitivity reactions.
