Swallow capsules whole. Do not split, crush, chew, or suck on the capsules. During treatment, the dosage may be adjusted according to response of the disease and/or adverse reactions, some of which may be dose-related. Adult patients whose disease is very severe with scarring or is primarily manifested on the trunk may require dosage adjustments up to 2 mg/kg/day for Amnesteem in divided doses with food, as tolerated (see Table 3).

2.3 Recommended
Duration of Use A course of treatment is 15 to 20 weeks. If the total nodule count has been reduced by more than 70% prior to completing 15 to 20 weeks of treatment, may discontinue Amnesteem. After a period of 2 months or more off treatment, and if warranted by persistent or recurring severe nodular acne, may initiate a second course of Amnesteem in patients who have completed skeletal growth. The use of another course of Amnesteem treatment is not recommended before a two-month waiting period because the patient's acne may continue to improve after a 15 to 20-week course of treatment. The optimal interval before retreatment has not been defined for patients who have not completed skeletal growth. Long-term use of Amnesteem, even in low dosages, has not been studied, and is not recommended. The effect of long-term use of Amnesteem on bone loss is unknown.
