Dyspnea on daptomycin: eosinophilic pneumonia.

We present a case of drug-induced acute eosinophilic pneumonia with characteristic imaging and bronchioloaveolar lavage (BAL) findings. Although not a common diagnosis, it is important to consider in the right clinical scenario, including a patient with presumed pneumonia that does not respond to typical treatment. Diagnosis is confirmed by bronchoscopy with BAL. For drug-induced types, treatment includes removal of the offending agent. Corticosteroids are used if symptoms are severe and can result in rapid clinical improvement.
