Short summary
This case report is the first description of severe metabolic acidosis due to flucloxacillin therapy without relevant comedication that we know of. The described patient had been treated with flucloxacillin for 14 d due to intraoperative evidence of multisensitive Staphylococcus aureus due to periprosthetic shoulder infection. In patients on flucloxacillin therapy, acidosis should therefore always be considered as a differential diagnosis of tachypnoea or impaired mental status.
