The COVID-19 brought a new model of sanitary behavior (social distancing, etc.) that may have reduced the transmissibility of respiratory diseases, reflecting in the number of antibiotic prescriptions. This study evaluated antibiotic prescriptions for children throughout Brazil, between 2014 and 2021. An interrupted time series was conducted to assess variations in antibiotic consumption by the 1-12-year-old children. Joinpoint regression was used to assess the monthly variations. 86 million prescriptions were evaluated. On average, there was a 54% reduction in prescriptions during the pandemic. Amoxicillin showed a reduction of 65%. Joinpoint regression showed that the pandemic altered the prescription growth curve, changing the trend to a 22% drop per month. The new sanitary behavior showed us that it is possible, decreasing the use of antibiotics, to control the children's respiratory health.
