Description
Nitrohem 100 SR Tablet is a prescription antibiotic containing Nitrofurantoin 100 mg in a sustained-release formulation. It is primarily used to treat and prevent bacterial infections of the urinary tract, including bladder infections (cystitis).
Unlike many antibiotics, Nitrofurantoin concentrates in the urine, allowing it to act directly against bacteria in the urinary tract while having minimal effects elsewhere in the body. It is effective against many common bacteria that cause UTIs but is not effective for viral infections such as the common cold or flu.
For the best results, Nitrohem 100 SR Tablet should be taken exactly as prescribed and the full course should be completed even if symptoms improve early.
