Frequently asked questions

What is Nitrofurantoin Milpharm used for?+
Nitrofurantoin Milpharm is indicated for the treatment of uncomplicated urinary tract infections, including cystitis, in adult patients. It works by eliminating the bacteria that cause infection within the urinary tract, helping to relieve symptoms such as dysuria, frequency, and urgency.
How does nitrofurantoin work?+
Nitrofurantoin is reduced by bacterial enzymes to reactive intermediates that damage bacterial DNA and inhibit key metabolic pathways. This bactericidal action prevents bacterial replication, leading to clearance of the infection, especially in the urinary tract where the drug achieves high concentrations.
What is the usual dose of Nitrofurantoin Milpharm?+
The dosage of Nitrofurantoin Milpharm is determined by the prescribing clinician based on the patient’s condition, renal function, and local treatment guidelines. The prescriber will specify the strength, frequency, and duration appropriate for the individual case.
