The typical directions on this page are nitrofurantoin 100 mg, taken as one capsule twice daily for 5 days. This is general product information, not a personal dosing order. Follow your prescribing physician’s directions and the pharmacy label. If they differ from this page, ask your pharmacist or physician to clarify before taking it.
A licensed physician in your state reviews your symptoms and health history to decide whether treatment is appropriate. Tell them about kidney problems, pregnancy, medication allergies, and any past reaction to nitrofurantoin. These details can affect whether this medicine is a safe choice. Do not use someone else’s prescription or leftover antibiotics.
Take only the prescribed amount. Taking extra capsules does not make treatment work faster and may increase side effects. If you accidentally take more than directed, contact Poison Control at 1-800-222-1222 for advice. Call 911 for severe symptoms, such as trouble breathing or collapse. Ask your care team if any part of your dosing schedule is unclear.
