Nitrofurantoin is an antibacterial agent frequently used in the management of urinary tract infections (UTIs). This antimicrobial drug is generally used in the following clinical settings:
●The short-term prophylaxis of infections acquired by invasive urologic diagnostic procedures and operations
●The long-term prevention of recurrent UTIs
●The treatment of acute or recurrent cystitis
The most common adverse reactions to nitrofurantoin (apart from turning the urine color a harmless brown) are nausea (8 percent), headache (6 percent), and flatulence (1.5 percent). Among the rare adverse reactions (<1 percent), pulmonary injury is the most severe .
