Furafix Tablet SR contains Nitrofurantoin 100mg, an effective antibacterial agent used primarily to treat urinary tract infections (UTIs) caused by susceptible strains of bacteria. Nitrofurantoin works by inhibiting bacterial enzymes involved in DNA, RNA, and cell wall synthesis, thereby preventing bacterial growth and replication. This sustained-release formulation ensures a gradual release of the active ingredient, maintaining therapeutic drug levels in the urinary tract over an extended period, which enhances efficacy and reduces dosing frequency. Furafix Tablet SR is indicated for uncomplicated UTIs, including cystitis and pyelonephritis, and is particularly useful in preventing recurrent infections. It is generally well-tolerated, but patients should be advised about potential side effects such as gastrointestinal discomfort, nausea, headache, and, rarely, pulmonary reactions or liver toxicity. It is contraindicated in patients with renal impairment, glucose-6-phosphate dehydrogenase deficiency, or known hypersensitivity to Nitrofurantoin. Adequate hydration is recommended during treatment to facilitate drug excretion through the urine. Furafix Tablet SR should be taken with food to improve absorption and minimize gastrointestinal irritation. As with all antibiotics, completing the full prescribed course is essential to prevent resistance development and ensure complete eradication of the infection.
