Isotretinoin 40 mg is a powerful oral medication primarily used to treat severe or cystic acne that hasn’t responded to other treatments. As a derivative of vitamin A, it works by reducing oil production in the skin, shrinking sebaceous glands, and preventing clogged pores. Typically prescribed in a course lasting 4 to 6 months, Isotretinoin is highly effective but may cause side effects such as dry skin, lips, and eyes. Due to its potential for birth defects, it requires strict medical supervision and pregnancy prevention measures. Always follow your dermatologist’s instructions and undergo regular checkups while on Isotretinoin 40 mg.
