Acne is increasingly being treated with low-dose isotretinoin (Accutane). Many isotretinoin patients have scars and markings from past acne. Although it is advisable to begin scarring therapy as soon as possible, there is still some risk about aberrant scarring when on isotretinoin. The most common problem is increased pigmentation, especially of the face. Scars may also become more noticeable because of loss of hair where they are located. It is important to remember that even though you may feel like you're recovering quickly from your last episode of acne, this skin damage needs time to heal itself. Any scarring effects of the medication will be temporary, but it is important to allow yourself time to heal before taking more isotretinoin. Isotretinoin can cause serious side effects. All patients going through treatment should discuss potential risks with their doctor before starting. Some examples include: depression, mood changes, anxiety, irritability, anger issues, trouble sleeping, muscle pain, weakness, headache, diarrhea, dry mouth, appetite change, urinary frequency or retention, vaginal bleeding or irritation, fever, cough, sore throat, chills, body aches, chest pains, shortness of breath. Isotretinoin should not be used by patients who are pregnant, may become pregnant, or are planning to get pregnant. It is also not recommended for use in children under 18 years old.
