ABSTRACT
ABSTRACT BACKGROUND:
Acne needs to be treated early to prevent negative psychosocial impacts. In severe or moderate forms, which tend to leave scars, oral isotretinoin is the first-line therapy. However, concern about its adverse events, especially in developed countries, delays effective treatment. In contrast, isotretinoin is widely prescribed in Brazilian private clinics.OBJECTIVES:
To describe the use of isotretinoin for treating acne in a Brazilian public hospital, and to analyze whether its prescription is effective or belated. DESIGN ANDSETTING:
Retrospective cohort study in a public hospital.METHODS:
Clinical and therapeutic data were obtained from the medical records of patients who were undergoing or had undergone acne treatment with isotretinoin in this hospital's general dermatology outpatient clinic over the last seven years, up to April 2018.RESULTS:
1526 medical records from patients with acne were analyzed. Isotretinoin was prescribed for 279 patients (18.28%) with mild (1.19%), moderate (57.37%), severe (35.85%) or conglobata (5.57%) forms of acne vulgaris. Sequelae of acne were present at the start of most of these patients' treatment. An initial daily dose of 20 mg was usually prescribed. The average initial dose/weight ratio was 0.33 mg/kg/day. The average total dose/weight ratio was 127.61 mg/kg. There were only a few cases of laboratory abnormalities.CONCLUSION:
Sequelae of acne at the onset of treatment reveal delayed indication of isotretinoin, which can have negative psychosocial impacts on quality of life. Isotretinoin should be indicated early to prevent this. Its use is supported by its lack of laboratory alterations and controllable adverse events.
