The standard isotretinoin dosage for treating severe acne generally follows these guidelines:
- Initial Dosage: Typically, the initial dose ranges from 0.5 to 1.0 mg/kg/day, taken in two divided doses.
- Maximum Dosage: In some cases, the dosage may be increased to 1.5 mg/kg/day, depending on the patient’s needs and tolerance.
- Treatment Duration: Treatment usually lasts for 15 to 20 weeks, but this can vary based on individual progress.
- Adjustment Period: Continuous monitoring during treatment allows for dosage adjustments based on the patient’s response and any side effects experienced.
Monitoring and Safety Precautions
Regular follow-ups with a healthcare provider are essential while on isotretinoin.
