Drug-induced eosinophilic lung disease

Eosinophilic lung disease can present as pulmonary infiltrates with blood eosinophilia or as increased eosinophils in bronchoalveolar lavage or histologic specimens. Prescribed medications, over-the-counter medications, herbal remedies, and street drugs can cause drug-induced eosinophilic lung disease. Several drugs have been reported to cause eosinophilic lung disease but certain drugs are more frequently implicated than others. The diagnosis primarily is based on the history and physical examination as well as exclusion of other eosinophilic lung diseases.
