Martifur 50 mg Tablet MR

Martifur 50 mg Tablet MR is an antibiotic tablet that contains nitrofurantoin 50 mg in each tablet. It belongs to the nitrofuran class and is used mainly for certain bacterial infections of the urinary tract, especially uncomplicated bladder infections. This modified-release tablet is designed to release the medicine gradually after swallowing. Your clinician may choose Martifur 50 mg Tablet MR when a lower, divided nitrofurantoin strength is preferred for a personalized treatment plan.

How it works: Nitrofurantoin works by entering bacteria in the urinary tract and damaging the processes they need to grow and survive. In Martifur 50 mg Tablet MR, the modified-release tablet helps deliver the medicine gradually so it can act in the urine over time.

Martifur 50 mg Tablet MR is the lower of the two strengths listed, compared with Martifur 100 mg Tablet MR. The 50 mg tablet may suit patients who need a smaller dose per tablet, a more flexible dosing schedule, or a regimen their doctor wants to build up in divided doses rather than using the higher-strength tablet. Because it is a modified-release tablet, it is meant to be swallowed whole and used only as directed for the specific infection and patient profile your doctor has assessed.

• Treatment of uncomplicated lower urinary tract infection
• Bladder infection caused by susceptible bacteria
• Short-course antibiotic therapy when prescribed for UTI
• Doctor-directed prevention of recurrent urinary infections in selected patients

• Swallow Martifur 50 mg Tablet MR whole with water; do not crush, chew, or break the modified-release tablet.
• Take it with food or milk to help improve absorption and reduce stomach upset.
• Take it exactly at the times prescribed and finish the full course, even if you feel better early.
• Do not use it for a kidney infection with fever, back pain, or chills unless your doctor specifically instructs you.
• If you miss a dose, take it when you remember unless it is almost time for the next dose; do not double up.
• Follow the exact schedule on your prescription, since the 50 mg tablet may be used in divided doses rather than as a single daily tablet.

Each Martifur 50 mg Tablet MR provides 50 mg of nitrofurantoin per tablet. The number of tablets you take, how often you take them, and the maximum daily amount depend on your infection, kidney function, and your doctor’s prescription; some regimens use multiple 50 mg tablets per day, but the exact dose must be individualized. Do not change the dose on your own, and do not compare it directly with Martifur 100 mg Tablet MR unless your prescriber tells you to.

Do not change your dose or stop the medicine without speaking to your doctor.

• This tablet can cause dizziness or headache in some people, so be careful driving or operating machinery until you know how it affects you.
