CompositionMartifur Tablet is an antibiotic used to treat and prevent bacterial urinary tract infections, such as cystitis, easing the burning and frequent urination they cause.
It contains nitrofurantoin, which concentrates in the urine. It works by damaging the bacteria in the urinary tract, which clears the infection.
Take it with food as prescribed, and complete the full course even if you feel better early. It may turn the urine a dark yellow or brown colour, which is harmless.
Tell your doctor about any kidney problems before use, as it is not suitable if kidney function is poor. Report breathlessness or a cough, or tingling or numbness in the hands or feet, especially with long-term use.
