What is Claravis and what does it do?


The medication Claravis® (isotretinoin) is prescribed to treat severe acne when antibiotics are not effective. Acne occurs when the skin's oil-secreting glands get clogged causing bacteria to grow in the pores and blemishes to form. Claravis® works by reducing the amount of oil (sebum) produced by your glands and shrinks the size of the glands. Although blemishes may worsen during the first two to three weeks of use, most people start to see improvements in about a month and the full effect in 3-5 months. The drug is effective 60 - 65% of the time.

Claravis® directions

Take the drug in doses by mouth two times a day with food or milk to increase the amount of the drug absorbed into your body. Doses range from 15 to 75 mg depending on your weight and the severity of your acne. Pregnant women or women trying to get pregnant should never take Claravis® because it carries the risk for miscarriage or serious birth defects.

As a result of the risk of miscarriage and defects, each month, Claravis® prescriptions must be hand-written by a doctor for no more than a 30-day supply. Each month, women taking Claravis must have a negative pregnancy test result. Because of this procedure, the drug is not available online. To learn more about the Claravis® dispensing procedures, visit the FDA Web site.
