Uriron 100 mg Tablet SR

Uriron 100 mg Tablet SR is a nitrofurantoin antibiotic tablet used to treat certain bacterial infections, most commonly urinary tract infections (UTIs). Each tablet contains 100 mg of nitrofurantoin in a sustained-release (SR) form, which is designed to release the medicine gradually. Uriron 100 mg Tablet SR should be used only for bacterial infections that a clinician has identified or strongly suspects.

How it works: Nitrofurantoin works by entering bacteria in the urinary tract and damaging the bacterial proteins, DNA, and other systems they need to grow and survive. Because Uriron 100 mg Tablet SR is a sustained-release tablet, the 100 mg dose is released gradually after swallowing, helping maintain antibiotic levels in the urine over time.

Uriron 100 mg Tablet SR is a higher-strength nitrofurantoin tablet, so it may be chosen when a prescriber wants 100 mg per dose in a sustained-release form rather than lower-strength tablets that require multiple units. Because it is an SR tablet, the medicine is released more slowly, which can help reduce how often it needs to be taken and may feel gentler on the stomach for some people.

• Treatment of uncomplicated urinary tract infections
• Treatment of bladder infection caused by susceptible bacteria
• Sometimes used for prevention of recurrent UTIs when prescribed
• Bacterial infections limited to the urinary tract

• Swallow Uriron 100 mg Tablet SR whole with a full glass of water; do not crush, break, or chew the tablet.
• Take it with food or milk to improve absorption and help reduce stomach upset.
• Take it exactly at the times prescribed, even if you start feeling better before finishing the course.
• Try to space doses evenly through the day if your doctor prescribes more than once daily.
• Keep drinking fluids unless your clinician has told you to limit fluids.
• Do not use this tablet for a viral illness or for an infection unless it has been prescribed for you.

Each Uriron 100 mg Tablet SR provides 100 mg of nitrofurantoin in one sustained-release tablet. The exact schedule depends on the infection and your doctor’s instructions; this strength may be taken once or twice daily for some patients, but the maximum daily amount and duration must be set by the prescriber. Do not take more tablets than directed, and do not assume the dose should match someone else’s prescription.

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

• Use caution if you have a history of liver disease, lung disease, nerve problems, or anemia.
• Take the tablet with food or milk to lower the chance of nausea and improve tolerability.
• Do not crush or split the SR tablet, because that can change how the medicine is released.
