Description: Diflorasone is a corticosteroid that comes in the form of a cream containing diflorasone diacetate. According the drug's maker, E. Fougera & Co., it is used for its anti-inflammatory and anti-itching qualities, like other topical corticosteroids. It is often prescribed for psoriasis and atopic dermatitis, and also for Hailey Hailey Disease (Familial Benign Pemphigus). and is considered to be of greater potency compared to other topical corticosteroids. No long-term animal studies have been done to determine whether diflorasone could have carcinogenic properties. (Source: http://en.wikipedia.org/wiki/Diflorasone)
