If you’ve ever been told to take nitrofurantoin, you probably know it’s an antibiotic for urinary‑tract infections (UTIs). It works by stopping bacteria from growing in the bladder, which helps clear the infection faster. Most people finish a 5‑ to 7‑day course and feel better within a couple of days.
While nitrofurantoin is effective, it’s not a one‑size‑fits‑all medicine. Your doctor will look at your kidney function, any allergies, and other meds you’re on before prescribing it. That’s why it’s worth knowing the basics: how to take it, what side effects to watch for, and when to call your doctor.
Take the tablets with food or milk. Food helps the drug absorb better and reduces stomach upset. Swallow the pills whole – don’t crush or chew them unless your doctor says it’s okay.
Common dosing is 50 mg to 100 mg twice a day, but your doctor might adjust the amount based on the infection severity and your health status. Finish the whole prescription even if you feel better; stopping early can let bacteria bounce back.
Keep a glass of water handy and stay hydrated. Drinking enough fluids flushes bacteria from your urinary system and can lessen the chance of a repeat infection.
Most people tolerate nitrofurantoin well, but a few side effects pop up. Look out for nausea, loss of appetite, or a mild rash. If you notice dark urine, that’s usually harmless and fades after the drug clears from your system.
Serious reactions are rare but need immediate attention: severe itching, swelling of the face or throat, or breathing trouble could mean an allergic reaction. Also, some folks develop lung issues if they take nitrofurantoin for a long time. If you develop a new cough, shortness of breath, or fever, talk to your doctor right away.
People with poor kidney function often can’t use nitrofurantoin because the drug won’t clear properly and could build up to unsafe levels. Your doctor will run a quick blood test to confirm your kidneys are working well enough.
