What is the main reason for prescribing Nitrofurantoin?

Nitrofurantoin is primarily prescribed for the treatment of urinary tract infections (UTIs). This antibacterial medication works by targeting bacteria in the urinary tract, making it particularly effective for cystitis and other infections located in the bladder and urinary system. It is not generally used for respiratory, skin, or gastrointestinal infections because its action is most effective in acidic urine, where it can concentrate and exert its antibacterial properties against common UTI pathogens. By understanding the specific application of Nitrofurantoin, it becomes clear why the treatment of urinary tract infections is the primary indication for this medication.
