Fution 100 Tablet contains Nitrofurantoin 100mg, an effective antibacterial agent primarily used to treat urinary tract infections (UTIs) caused by susceptible strains of bacteria. Nitrofurantoin works by interfering with bacterial enzymes involved in DNA, RNA, and cell wall synthesis, thereby inhibiting bacterial growth and replication. It is particularly effective against common UTI pathogens such as Escherichia coli, Enterobacter, and Staphylococcus saprophyticus. Fution 100 is indicated for the treatment and prevention of acute and chronic lower urinary tract infections. The medication is absorbed rapidly from the gastrointestinal tract and is excreted mainly through the urine, ensuring high concentrations in the urinary tract where the infection resides. It is important to take Fution 100 with food to enhance absorption and reduce gastrointestinal discomfort. Patients should complete the full prescribed course even if symptoms improve early to prevent recurrence and resistance development. Common side effects may include nausea, headache, and mild gastrointestinal disturbances. Fution 100 is contraindicated in patients with renal impairment, pregnancy at term, or known hypersensitivity to nitrofurantoin. Always consult a healthcare professional before use to ensure appropriate therapy and dosage adjustments based on individual health status.
