Triamcinolone was patented in 1956 and came into medical use in 1958. It is available as a generic medication. In the United States the wholesale cost is about US$0.06 per gram for the cream. In 2016 it was the 122nd most prescribed medication in the United States with more than 6 million prescriptions.
Triamcinolone is used to treat a number of different medical conditions, such as eczema, lichen sclerosus, psoriasis, arthritis, allergies, ulcerative colitis, lupus, sympathetic ophthalmia, temporal arteritis, uveitis, ocular inflammation, keloids, urushiol-induced contact dermatitis, aphthous ulcers (usually as triamcinolone acetonide), central retinal vein occlusion, visualization during vitrectomy and the prevention of asthma attacks.
The derivative triamcinolone acetonide is the active ingredient in various topical skin preparations (cream, lotion, ointment, aerosol spray) designed to treat skin conditions such as rash, inflammation, redness, or intense itching due to eczema and dermatitis.
Side effects of triamcinolone include sore throat, nosebleeds, increased coughing, headache, and runny nose. White patches in the throat or nose indicate a serious side effect. Symptoms of an allergic reaction include rash, itch, swelling, severe dizziness, trouble breathing.
