Cross-sectional study. From a population database, a random sample of patients treated in an outpatient consultation was obtained, to identify the indications of the prescribed cephalosporins in their clinical record. Pharmacological variables, and those related to non-indicated formulations were evaluated according to the clinical practice guidelines. In 381 patients, the mean age was 41.2 ± 15.4 years, and 61.4% (n = 234) were women. Cefalexin was the most widely used (n=318; 83.5%), with a mean duration of treatment of 7.3 ± 3.2 days; followed by cefradine (n = 43; 11.3%), and ceftriaxone (n = 20; 5.2%). The most common uses were for skin and soft tissue infections (n = 177; 46.4% of which 47.5% were purulent), urinary tract infections (n = 70; 18.4%), upper respiratory airway infections (n = 57; 15.0%) and sexually transmitted diseases (n = 21; 5.5%). The use was considered indicated in 169 patients (44.4%), but only 103 (60.9%) had prescriptions that met the dosage recommendations from the clinical practice guidelines. More than half of the patients prescribed with cephalosporins in the outpatient setting had prescriptions considered not indicated, particularly for their use in purulent skin and soft tissue infections.
