Nitrofurantoin Tablets SR 100 Mg

Description

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

Nitrofurantoin Tablets SR 100 Mg are a sustained-release formulation used for the treatment and prevention of urinary tract infections (UTIs), providing prolonged antibacterial activity in the urinary tract. This formulation helps maintain consistent drug levels, improving treatment effectiveness and convenience. For patients requiring a lower dose or initial therapy, Nitrofurantoin Tablets 50 mg may be considered under medical supervision.

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

• 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
