Accutane is the trade name for isotretinoin. Accutane is also known as Roaccutane. Accutanes main use is to cure severe acne when other treatments have failed.
For information about the use of accutane, the side effectsof accutane, and some personal experiences of it's use; I reccomend the Acne and Roaccutane website. This site also has a links page to other accutane related pages, should you require more information.(accutane is often misspelled accunan or acutan)
For a selection of other (non accutane) interesting sites on the net, why not try my own sites list.
