Cloxacillin is a commonly prescribed antibiotic for Methicillin-sensitive Staphylococcus aureus (MSSA) caused infections. We report a case of transient Cloxacillin induced agranulocytosis with eosinophilia and elevated IgE levels. Agranulocytosis is a life threatening condition, drugs are the most common cause and our knowledge and evidence of the relationship between drug use and agranulocytosis builds up and accumulates from case reports and observations. It is important to keep adding drugs to the list of potential causative drugs especially since monitoring blood count is simple and can be life saving.
