- Previous Treatments: Patients who have not responded well to other treatments may require a higher dose.
- Patient’s Health Condition: Existing health issues can affect how the body processes isotretinoin, thus influencing dosage.

While individual treatment plans will vary, typical isotretinoin dosages usually follow these guidelines:
- Initial dosage: Commonly ranges from 0.5 mg to 1 mg per kg of body weight.
- Duration of treatment: Generally lasts between 15 to 20 weeks.
- Maximum cumulative dose: Often targeted to be between 120 mg to 150 mg per kg over the entire treatment period.
Monitoring and Adjustments
After starting isotretinoin, patients should be monitored regularly. It is essential to assess:
- Side effects: Common side effects include dry skin, dry eyes, and possible mood changes.
- Effectiveness: Regular follow-up appointments help determine if the dosage needs adjustment.
