For details on evidence and safety measures and risk mitigation measures, see the sections on conditions it is able to treat and safety characteristics and therapy is not indicated due to these conditions.

Principal active ingredient

The pharmacologically active substance is nitrofurantoin. It is available in generic forms and may be sold under different brand names in the country of Australia. Formulations differ and these differences affect dosing frequency and release profile.

Which uses does nitrofurantoin have?

Its main role is treating uncomplicated lower urinary tract infections, for example acute cystitis. It may also be used to prevent recurrent lower UTIs in selected patients.

Nitrofurantoin is generally not recommended for suspected kidney infections (pyelonephritis) or for systemic infections because it achieves high concentrations in urine but not in blood or kidney tissue in the same way.

Available forms and typical strengths

In Australia the common presentations include:

• 100 mg tablets or capsules, with some modified-release preparations among these
• 50 mg capsules or tablets for oral administration

Prescribers choose dose and duration based on the type of infection, kidney function, age and other clinical factors. Always follow the dose and duration given by your prescriber.

How to take a break nitrofurantoin

• Follow the directions on the prescription label and any advice from your pharmacist.
• Take doses with food or a meal to reduce stomach upset and to help absorption.
• Avoid antacids that contain magnesium trisilicate during therapy, as they can lower absorption. Ask your pharmacist for safe antacid choices when the need arises.
• Keep well hydrated unless you have been advised otherwise by your clinician.
• Complete the full prescribed course even if symptoms improve early, to reduce the chance of relapse and antibiotic resistance.
