Accutane or Isotretinoin is used for acne treatment. This drug works by reducing the amount of oil released by oil glands in the skin. Accutane is prescribed for treating very severe forms of acne, such as cystic or nodular acne. Symptoms of such acne may include swollen, red bumps on the skin that cause physical pain and scarring if not properly treated.

The dose of Accutane (isotretinoin) will vary, depending on a number of factors, including:
* The severity of your acne
* Your weight
* How you respond to the drug.

In most cases, the recommended dose of Accutane is 0.5 mg to 1 mg per kg of body weight (about 0.23 mg to 0.45 mg per pound) each day, divided into two daily doses. For adults with severe acne or acne limited mostly to the trunk of the body, a dose of 2 mg per kg (about 0.91 mg per pound) each day, divided into two daily doses, may be necessary.

There may be temporary worsening of acne before it gets better. Your doctor will adjust your daily dose after the initial treatment to between 0.1 mg and 1 mg per kilogram of body weight depending on your response to the medication.

Typically, Accutane is taken for 15 to 20 weeks. Your acne will continue to improve after you stop taking the medication. A second course may be recommended if your acne is still a problem eight weeks after finishing the first course.
