Systemic lupus erythematosus (SLE) is a chronic and potentially fatal autoimmune disease. There are clinical differences between women and men and among age groups. Its treatment involves a heterogeneous group of drugs. The objective was to determine the pharmacological treatment patterns in a group of patients with SLE and compare them according to sex, age group and geographic region. This was a cross-sectional study that identified outpatient drugs used in patients with SLE from a population database of Colombians affiliated with the Colombian Health System. Sociodemographic and pharmacological variables were considered. Descriptive and bivariate analyses were performed. A total of 4307 patients with SLE were identified (median age, 44.2 years; 89.4% women). Disease-modifying antirheumatics were the most prescribed drugs (90.5%), especially chloroquine (54.4%), which predominated in all age groups and geographical regions. Hydroxychloroquine and methotrexate were the predominant prescribed drugs for women, while corticosteroids, chloroquine, azathioprine, and mycophenolate were the predominant prescribed drugs for men. The use of corticosteroids (prednisolone and prednisone) decreased with increasing age. Differences were found in the prescription of drugs for patients with SLE between women and men and among geographic regions and age groups. The use of chloroquine predominated over hydroxychloroquine, contrasting with clinical practice guidelines.
