Roaccutane 20 mg is a prescription medication manufactured by Roche Bangladesh Ltd., containing isotretinoin, a retinoid derived from vitamin A. It is primarily used to treat severe forms of acne, such as nodular or conglobate acne, that have not responded to other treatments like antibiotics or topical therapies. Roaccutane works by reducing sebum production, decreasing the size and activity of sebaceous glands, and preventing pore blockages, thereby addressing the underlying causes of acne.
The typical dosage for Roaccutane is 0.5 mg per kilogram of body weight per day, taken with food. For example, a person weighing 60 kg would start with a daily dose of 30 mg. Treatment usually lasts between 16 to 24 weeks, and in most cases, a single course is sufficient to achieve long-term remission. However, a second course may be considered if acne recurs after at least 8 weeks.
