[Drug-induced lung disease in general practice].

Adverse medical side effects are an important health issue causing morbidity and mortality. Lungs, being a complex system are also involved. Cough, bronchospasms and buccopharyngeal oedema are the main drug-induced reactions at the airways level. With regard to pulmonary parenchyma, this can result in almost all forms of interstitial lung disease such as usual interstitial pneumonia, non specific interstitial pneumonia, lung oedema, eosinophilic lung disease. Certain drugs are often involved and cause specific clinical pictures (amiodarone, methotrexate). Lung vasculature, pleura and thoracic wall can also be affected. Drug-induced pulmonary disease is an exclusion diagnosis and the main therapeutic action is to stop administration of the suspected drug.
