Zenatane should be administered with a meal (see PRECAUTIONS: Informationfor Patients).
The recommended dosage range for Zenatane is 0.5 to 1.0 mg/kg/day given in two divided doses with food for 15 to 20 weeks. In studies comparing 0.1, 0.5, and 1.0 mg/kg/day,8 it was found that all dosages provided initial clearing of disease, but there was a greater need for retreatment with the lower dosages. During treatment, the dose may be adjusted according to response of the disease and/or the appearance of clinical side effects — 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 dose adjustments up to 2.0 mg/kg/day, as tolerated. Failure to take Zenatane with food will significantly decrease absorption. Before upward dose adjustments are made, the patients should be questioned about their compliance with food instructions.
The safety of once daily dosing with Zenatane has not been established. Once daily dosing is not recommended.
If the total nodule count has been reduced by more than 70% prior to completing 15 to 20 weeks of treatment, the drug may be discontinued. After a period of 2 months or more off therapy, and if warranted by persistent or recurring severe nodular acne, a second course of therapy may be initiated. The optimal interval before retreatment has not been defined for patients who have not completed skeletal growth. Long-term use of Zenatane, even in low doses, has not been studied, and is not recommended. It is important that Zenatane be given at the recommended doses for no longer than the recommended duration. The effect of long-term use of Zenatane on bone loss is unknown (see WARNINGS: Skeletal: BoneMineral Density, Hyperostosis, and Premature Epiphyseal Closure).
Contraceptive measures must be followed for any subsequent course of therapy (see PRECAUTIONS).
