Nitrofurantoin Pulmonary Toxicity: Neglected Threat. Current drug safety [Curr Drug Saf] Journal article

Nitrofurantoin lung toxicity was diagnosed among ten patients receiving 50 mg/day to prevent recurrent urinary tract infection. In six patients a symptomatic period of 3-36 months preceded the diagnosis. All but one patient, with irreversible lung injury at presentation recovered completely, five after drug discontinuation and four after steroids therapy. Large amount of data regarding unexpected, sometimes severe pulmonary toxicity during nitrofurantoin therapy should maintain a high index of suspicion for the drug usage among patients with non-resolving pulmonary symptoms. Alternatively, the use of other anti-microbial agents with a better risk-to-benefit ratio should be considered.
