1. Determining the Right Dosage

The dosage of isotretinoin is tailored to each individual based on several factors, including:

1. Severity of Acne: More severe cases may require higher doses.

For most patients, the initial dosage typically ranges from:

• 0.5 to 1.0 mg/kg per day for moderate cases
• 1.0 to 2.0 mg/kg per day for severe cases.

These doses are usually divided into two or three administrations per day. It’s crucial for patients to follow their healthcare provider’s instructions carefully.

3. Maximum Dosage and Duration of Treatment

The maximum recommended cumulative dose is around 120-150 mg/kg over the entire course of treatment, which usually spans 15 to 20 weeks. Treatment duration should be personalized, and patients must consult with their healthcare provider to determine the best plan.

4. Monitoring and Adjustments

Regular follow-ups are essential to monitor the patient’s response to isotretinoin. Adjustments in dosage may be necessary based on:

• Side effects experienced
