Fatal nitrofurantoin lung

Area of Science:

• Pharmacology
• Pulmonology
• Toxicology

Background:

• Nitrofurantoin is a first-line antibiotic for uncomplicated urinary tract infections (UTIs).
• Its mechanism of action involves damaging bacterial DNA.
• While generally safe, nitrofurantoin is associated with rare pulmonary toxicity.

Observation:

• An elderly female patient was treated with oral nitrofurantoin for a UTI.
• The patient developed sudden onset acute lung injury.
• The condition rapidly progressed despite treatment.

Findings:

• The case demonstrates a fatal outcome from nitrofurantoin-induced acute lung injury.
• Pulmonary toxicity from nitrofurantoin, though typically reversible, can be fatal in rare instances.
• This underscores the potential for severe adverse reactions even with commonly prescribed medications.

Implications:

• Clinicians should maintain a high index of suspicion for drug-induced lung injury in patients on nitrofurantoin.
• Early recognition and discontinuation of the offending agent are crucial for managing nitrofurantoin pulmonary toxicity.
• This case emphasizes the need for careful patient monitoring and risk-benefit assessment in antibiotic therapy.
