Martifur MR 100 Tablet is an antibiotic used to treat and prevent bacterial urinary tract infections (UTIs). It treats susceptible infections of the bladder but not kidney infection (pyelonephritis) and relieves symptoms such as burning on passing urine and lower abdominal discomfort.
It contains nitrofurantoin, in a modified-release form that concentrates in the urine. It works by damaging the bacteria in the urinary tract, which stops them growing.
Take it with food or milk to improve absorption and reduce stomach upset, and complete the full course. Drinking plenty of fluids helps flush out bacteria. It may turn the urine dark, which is harmless.
Tell your doctor about any severe kidney disease, liver problems or G6PD deficiency before starting. Report numbness or tingling, or a new cough or breathlessness, especially with longer use.
