  3. Maximum Dose: In some severe cases, short courses of up to 2 mg/kg/day may be prescribed for limited periods.

Monitoring and Follow-Up

Regular monitoring is essential throughout treatment. Patients should attend follow-up appointments to assess their skin’s response and adjust the dosage if necessary. Blood tests may also be required to monitor liver function and lipid levels during the course of treatment.
