If you have gonorrhea, prostatitis, or a urinary tract infection, your healthcare provider may prescribe norfloxacin. Your dosage of this medication will depend on the type of infection being treated and your kidney function. Even if you feel better after a few days, finish the entire course of the antibiotic so that your infection does not return.
The dose of norfloxacin (Noroxin®) your healthcare provider recommends will depend on a number of factors, including:
- The type and severity of the infection being treated
- How well your kidneys function.
As is always the case, do not adjust your dosage unless your healthcare provider specifically tells you to do so.
Make sure to follow your healthcare provider's instructions carefully and to finish the entire course of norfloxacin, even if you start to feel better. Stopping this medication too soon could cause your infection to come back or lead to the development of antibiotic-resistant bacteria.
The usual dose of norfloxacin for treating a urinary tract infection (UTI) is 400 mg every 12 hours for 3 to 21 days, depending on the severity of the infection and the type of bacteria causing it. However, people with kidney disease may need a lower amount (400 mg just once daily).
The recommended dose of norfloxacin for gonorrhea is 800 mg (two 400-mg tablets) as a single, one-time dose. Ask your healthcare provider if your sexual partners need to be treated as well.
The recommended dose of norfloxacin for treating prostatitis is 400 mg twice daily for 28 days. Although there are no specific dosing recommendations for treating prostatitis in people with kidney disease, a once-daily amount (400 mg once daily) may be reasonable.
