Medication-induced Lung Disease Flashcards
Pulmonary injury due to medications occurs as a result of
- allergic reactions
- idiosyncratic reactions
- overdose
- undesirable side effects
- in most, mechanism of injury is unknown
Precise diagnosis of medication induced pulmonary disease is
- difficult bc routine lab studies to helpful and radiographic findings not specific
- need high index of suspicion and thorough history of medication use
- response to cessation of med is helpful in Dx
Acute episodes of medication induced pulmonary disease vs chronic
- acute: disappear 24-48 hrs after med discontinued
- chronic: longer to resolve
- challenge tests to confirm Dx are risky and rarely performed
Treatment of medication induced lung disease
discontinue offending agent immediately and manage pulmonary symptoms
Inhalation of crack cocain–pulmonary syndromes
-pulmonary infiltration with eosinophilia, pneumothorax, pneumomediastinum, bronchiolitis obliterates and acute respiratory failure associated with DAD and alveolar hemorrhage
Alveolar hemorrhage treatment
Corticosteroids
-Variable success
