Isotretinoin (Accutane) is available as capsules in the following strengths: 5, 10, 20, 30, and 40 milligrams. The recommended dose depends on your body weight. Usually you take a pill with food twice a day for a total of 15 to 20 weeks. (In Europe, patients are often given lower dosages for longer periods of time.) Initially, your doctor may decide to start you off on a low dose so that you can get used to any side effects and then the dosage can be increased.

In the vast majority of isotretinoin (Accutane) users, complexions smooth out, marks fade, and acne improves dramatically. Some lesions may still remain after you have stopped treatment, but many individuals notice that their acne continues to improve even in the weeks after treatment has stopped. (more…)
