What Are Nitrofurantoin Tablets SR 100 Mg?

Nitrofurantoin is a broad-spectrum antibacterial agent belonging to the urinary anti-infective class. Unlike many antibiotics that act systemically, nitrofurantoin achieves high concentrations in the urinary tract, where most uncomplicated lower UTIs originate.

How It Works

Nitrofurantoin enters susceptible bacterial cells and is converted into reactive intermediates that attack essential bacterial enzymes and DNA, inhibiting growth and leading to bacterial cell death in the bladder.

Therapeutic Uses

Nitrofurantoin Tablets SR 100 mg are prescribed for:

Treatment of uncomplicated urinary tract infections (UTIs) such as cystitis.
Prevention of recurrent UTIs in individuals prone to frequent infections.

Nitrofurantoin is generally not recommended for kidney (pyelonephritis) or systemic infections because it achieves high concentrations predominantly in the urine.

Dosage & Administration

The typical adult dosage for uncomplicated UTI is 100 mg twice daily for 5 to 7 days or as directed by a healthcare provider. It is best taken with food or milk to improve absorption and reduce stomach upset.

Important: Always follow the dosage prescribed by your doctor and complete the full course to ensure the infection is fully treated.

Important Safety Information & Precautions

Before taking Nitrofurantoin 100 mg:

Inform your healthcare provider about allergies to nitrofurantoin or similar drugs.
It should be used with caution in people with kidney dysfunction, as reduced renal function can affect drug effectiveness and safety.
Discuss use in pregnancy or breastfeeding with your doctor, especially near term.
Nitrofurantoin is not recommended in infants under one month old due to risk of serious side effects.

Side Effects

Common reactions may include:

Nausea, vomiting, or loss of appetite
Diarrhea
Headache
Dizziness
Urine may appear dark colored (harmless)

If you experience severe symptoms such as widespread rash, difficulty breathing, persistent coughing, or signs of liver or lung problems, stop the medication and seek medical advice immediately.
