How long can I take Isotretinoin 20 mg? Isotretinoin 20 mg is typically prescribed for severe acne and is usually taken for 15 to 20 weeks (about 4 to 5 months). The exact duration depends on the severity of acne, response to treatment, and individual tolerance. Most patients complete a single course within this period, but in some cases, a second course may be needed after a break. Doctors determine the total dosage based on body weight, usually aiming for 120-150 mg per kg to maximize long-term effectiveness. While isotretinoin is highly effective, prolonged use beyond the recommended course is not advised due to potential side effects, including dry skin, liver strain, and increased cholesterol levels. Always follow your doctor's instructions and attend regular check-ups to monitor for side effects. If acne persists after treatment, consult your dermatologist for alternative options. Never take isotretinoin without medical supervision. visit : https://www.dosepharmacy.com/isotroin-20mg-capsule
