Respiratory distress due to minocycline-induced pulmonary lupus.

Minoeycline, a semisynthetic tetracycline, is often used to treat acne and rheumatoid arthritis. It has been considered an unlikely drug to be associated with systemic lupus erythematosus; however, many cases of drug-induced lupus related to minocycline have been reported. Some of those reports included pulmonary lupus, but none of the patients described developed respiratory distress. We describe a patient treated with minocycline for 2 years who presented with progressive dyspnea, severe hypoxia, and pulmonary infiltrates necessitating hospitalization and oxygen supplementation.
