A variety of prescription medications are used today to clear acne. Topical (applied to the skin) medications may be prescribed for mild to severe acne. Systemic (works internally) therapy is needed to treat severe acne and may be used for moderate cases. These medications, which play an important role in acne treatment, attack the different factors that lead to acne. To achieve long-term control and resolution, dermatologists may combine therapies. The following describes the prescription medications used in the United States to treat acne:
Interlesional Corticosteroid Injection
When an acne cyst becomes severely inflamed, there is a good chance that it will rupture and scarring may result. To treat these severely inflamed cysts and prevent scarring, dermatologists may inject such cysts with a much-diluted corticosteroid. This lessens the inflammation and promotes healing. An interlesional corticosteroid injection works by "melting" the cyst over a period of 3 to 5 days.
