Definition Return to top
Drug-induced pulmonary disease is a lung disease caused by an adverse reaction to a medication.Causes, incidence, and risk factors Return to top
Many types of lung injury can result from medications, and it is often impossible to predict who will develop lung disease resulting from a medication or drug. The types of lung diseases which can result from medications include: allergic reactions (asthma, hypersensitivity pneumonitis, or eosinophilic pneumonia), an undesirable side effect such as coughing or bronchitis, inflammation of the lung air sacks (pneumonitis or infiltration), interstitial fibrosis (scarring), pulmonary edema, alveolar hemorrhage (bleeding into the lung air sacks), pleural effusion, lung vasculitis, mediastinal inflammation, swollen lymph nodes (lymphadenopathy), respiratory failure, granulomatous lung disease, and drug induced systemic lupus erythematosus.
Numerous drugs are known to cause lung (pulmonary) disease in some people including chemotherapy agents, certain antibiotics, illicit drugs, certain cardiovascular drugs, and many others.

Treatment Return to top
Treatment consists mainly of discontinuing the offending drug immediately, and supportive management of the pulmonary symptoms (e.g., inhaler therapy and oxygen if required until the drug-induced lung disease improves.) Challenge tests (reintroducing the suspected medication to see if symptoms recur) are rarely performed. Steroid therapy (such as prednisone) to quickly reverse the lung inflammation caused by the offending drug is sometimes used.Expectations (prognosis) Return to top
Acute episodes usually resolve within 48 to 72 hours after the medication has been discontinued, but chronic syndromes may take longer to resolve. Some drug-induced lung diseases such as pulmonary fibrosis (scarring) may never resolve.Complications Return to top
Calling your health care provider Return to top
Call your health care provider if symptoms of this disorder occur.Prevention Return to top
Previous reaction to medication in a person should be noted so that the medication can be avoided. A medical allergy bracelet should be worn by those with known drug reactions. Avoiding the abuse of illicit drugs prevents the many drug-induced lung diseases that are caused by these drugs. Update Date: 10/28/2003 Updated by: Allen J.
