  1. Initial Dosage: Patients usually start with a dosage of 0.5 to 1 mg per kg of body weight per day.
  2. Maintenance Dosage: After the initial treatment period (usually 15 to 20 weeks), the dosage may be adjusted based on the patient’s response, ranging from 0.5 to 1.5 mg per kg per day.
  3. Maximum Dosage: The maximum permissible dosage is generally 2 mg per kg per day, but this should be determined by a healthcare professional.
