Daptomycin is a bactericidal antibiotic accredited by the National Sanitary Surveillance Agency, in Brazil in 2009. In the United States, it was released in 2003 for the treatment of skin infections and soft tissues caused by gram-positive cocci. It is known that Fase IV studies, which information is obtained as from real conditions, are of great relevance in pharmacovigilance scope. So, it was objectified to analyse the incidence of adverse drug reactions (ADRs) in hospitalized patients submitted to daptomycin therapy. It is a cohort study. The sample was compounded by nine adult patients who were hospitalized during June 2010 to June 2012. Th e gathering of data was retrospective using medical records. Th e ADRs causalities were determined by Naranjo Algorithm. The project was approved by the Research Ethics Committee with human beings from NTOI (n° 0045.0.305.000-11). Th e patients’ average age was 57 years old, 66% from the female sex, the hospitalization average was 37 days and in 89% of the patients the use of daptomycin was for the treatment of MRSA infections. Th e incidence of ADRs associated with daptomycin was 55% and the ADRs identified were related to the respiratory, digestive, hematopoietic, central nervous and immune systems. It is concluded that in the ADRs notification, especially drugs that are in the market for less than 5 years, the precisive description of the event is essential, even if through a weak evidence study.
