Commercial pens will be used and the information given in the packaging will be applicable. The initial daily dose will be 0.6 mg for one week, 1.2 mg the following week and then 1.8 mg for the remaining treatment period. The injection is administered once daily in the morning. The maximal plasma concentration is reached 8-12 hours after subcutaneous injection. The half-life in plasma is approximately 13 hours. The duration of effect is 24 hours.
