4. Previous Treatments: Patients’ history with other acne treatments can influence the isotretinoin schedule and dosage.

Understanding general dosage guidelines can help patients prepare for their treatment:

1. Initial Dosage: Usually starts between 0.5 mg to 1 mg per kilogram of body weight, taken once or twice daily.
2. Maintenance Dosage: If needed, the dosage may be increased based on the patient’s response after a few weeks.
3. Course Length: Treatment typically lasts between 15 to 20 weeks, depending on the response to the medication.
4. Maximum Dosage: The total cumulative dose should ideally be around 120 to 150 mg/kg for best results.
