Nitrofurantoin (Macrobid) is an antibiotic to treat and prevent urinary tract infections (UTIs), including acute uncomplicated infections, recurrent infections, cystitis, and urethritis. Available in 50 and 100 mg tablets, Nitrofurantoin targets bacteria in the urinary tract effectively while minimizing systemic side effects. It is commonly prescribed for a 7-day course of treatment. This medication is well-tolerated, with a low risk of developing antibiotic resistance. Patients with kidney issues should use it cautiously, and it requires a prescription. Always follow the doctor’s instructions and store the medication out of the reach of children.
