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. In 2014, the FDA made triamcinolone acetonide an over-the-counter drug in the United States in nasal spray form under the brand name Nasacort.
