Nitrowin-100 Tablets contain Nitrofurantoin Sustained Release 100 mg, a prescription antibiotic used primarily for the treatment and prevention of urinary tract infections (UTIs) caused by susceptible bacteria. The sustained-release formulation helps provide a gradual release of the medicine for prolonged antibacterial action.

Nitrofurantoin works by interfering with essential bacterial processes, helping eliminate infection-causing bacteria in the urinary tract. The tablets should be taken exactly as prescribed by a healthcare professional, preferably with food to improve absorption. Each pack contains 10 strips of 15 tablets (10 × 15 tablets).
