Abstract
The use of isotretinoin over a 2-year period was retrospectively studied in Saskatchewan. The database of the Saskatchewan Prescription Drug Plan was used to obtain the names of physicians who prescribed isotretinoin as well as the names of patients for whom it was prescribed. Of the 861 such patients 161 had been instructed to use the drug for at least 4 months by 42 physicians. Questionnaires were returned by 86 of the 161 patients and 22 of the 42 physicians. The responses confirmed that isotretinoin therapy is highly effective for acne. However, at least half of the patients for whom the agent was prescribed apparently did not complete a full 4- to 5-month course of treatment, and of the 34 women (average age 28 years) who responded to the questionnaire 12 (35%) did not use a method of contraception, which is a matter of concern in view of isotretinoin's teratogenic effects.
