Triamcinolone acetonide cream is used topically to treat a variety of skin conditions, including dermatitis; psoriasis; rashes due to allergic reactions; and anal and genital itching, according to WebMD. It also treats cutaneous T-cell lymphoma. As a medium-to-strong corticosteroid, triamcinolone acetonide cream works to alleviate itching, swelling and redness of the skin.
Doctors instruct patients to apply the cream to the affected area two to four times per day and rub it in gently, notes WebMD. Patients are not to bandage or otherwise cover the area, and they must avoid getting the cream in the eyes, nose or mouth. Triamcinolone acetonide cream may cause irritation, dryness, itching or burning during the first few days of use, but these effects usually dissipate as the body acclimates to the medication. Possible side effects that need to be reported to a doctor include worsening of skin infections, acne, thinning or discoloration of the skin, pronounced increase in hair growth, stretch marks and folliculitis, or hair bumps.
If the medication is absorbed into the bloodstream, WebMD lists headache, extreme fatigue, weight loss, swollen feet or ankles, visual difficulties and increased thirst and urination as possible symptoms of excess corticosteroid in the body. Signs of serious allergic reaction, while rare, include swelling of the face, tongue or throat; rash; extreme dizziness; and breathing difficulties. These symptoms require immediate medical attention.
Triamcinolone acetonide also comes in the form of a dental paste for the treatment of mouth sores and ulcers. In veterinary medicine, triamcinolone acetonide is approved for use in dogs and cats by prescription only. It is employed to treat allergic dermatitis, rashes due to infections and eczema, according to PetMD and Vetstreet.
Triamcinolone acetonide falls into a class of medications known as corticosteroids, and it is often sold under the brand names Aristocorn and Triderm.
