[Hypersensitivity pneumonitis in a patient taking pravastatin].

A 41-year-old man who had been taking pravastatin for two years developed hypersensitivity pneumonitis. The initial examination found intestinal pneumonitis and hypereosinophilia. The patient's syndromes gradually resolved with withdrawal of pravastatin. As HMG coenzyme A reductase inhibitors are commonly prescribed, any respiratory symptoms in this setting should be considered with special attention.
