Product Description
Norfloxacin 400mg tablets are a type of antibiotic medication used to treat various bacterial infections. It belongs to a class of drugs called fluoroquinolone antibiotics. Norfloxacin works by stopping the growth of bacteria, effectively fighting off infections.
Uses:
Norfloxacin 400mg tablets are prescribed for a variety of bacterial infections, including:
- Urinary Tract Infections (UTIs): This includes both uncomplicated cystitis (bladder infection) and more serious infections like acute pyelonephritis (kidney infection).
- Sexually Transmitted Infections (STIs): Norfloxacin is effective against susceptible strains of Neisseria gonorrhoeae, the bacteria responsible for gonorrhea.
- Other Infections: Norfloxacin may be used for other infections, including traveler's diarrhea, but it is not the first-line choice for all bacterial infections.

The recommended dosage of norfloxacin varies depending on the type and severity of the infection being treated. Typically, adults take 400mg twice daily (every 12 hours).

- Multiple Doses: For more severe or complicated infections, a higher dose of 400mg twice daily may be necessary.
