I have been prescribed 50mg nitrofurantoin for 3 days (12tabs) for a uti. I have already taken 4 and feel no different, is this normal?

I have been prescribed 50mg nitrofurantoin for 3 days (12tabs) for a uti. I have already taken 4 and feel no different, is this normal?

Yes, but 50mg is low: Symptoms may take 2 - 3 days to subside. Most dr. S prescribe 100mg 3 or 4x a day, or Macrobid 100 mg twice a day. Need to get urine rechecked if symptoms persisit more than 3 days because infecting organism may not be sensitive to macrodantin. In which case another antibiotic like Bactrim or Cipro (ciprofloxacin) may be necessary. Suggest urine culture & sensitivity test is performed if infection still present. ...Read more

Have a UTI but when use nitrofurantoin 5 days still have the same pain in back > what medicine for tissues active need to take and what period?

Back pain and UTI: If your back pain is actually due to a UTI you should not be taking Nitrofurantoin since you probably have an upper tract infection. You really need to be fully evaluated by a doctor familiar with utis (infectious disease expert, urologist, nephrologist) and if not due to UTI your back pain also needs to be assessed differently. ...Read more

Doctor told me to take 1 nitrofurantoin after & before intercourse. Within how many hours afterwards should I be taking it for it to be effective?

UTI prophylaxis: Nitrofurantoin Rxd for you to take before and after intercourse is mostly likely most likely is because you had been having recurrent UTIs after intercourse and this should decrease the number that you have. Since it is a medication that would normally have to be Rxd 4 times per day for regular treatment take the second dose within 6 hours after the first dose you took before intercourse. ...Read more

Why does my body feel so cold after taking my last dose of nitrofurantoin? Kind of like fever but do not actually feel sick. Side effect?

Why does my body feel so cold after taking my last dose of nitrofurantoin? Kind of like fever but do not actually feel sick. Side effect?

?: Some people have just fever from a drug and the condition is called drug fever. The mechanism is unknown. You may also have chills (sensation of being cold) before the fever comes on. Given that you only had this sensation after having taken the last dose, the diagnosis is uncertain but it would still be wise to avoid this drug in the future since there are other options. ...Read more

Can you mix nitrofurantoin and levofloxacin or are they antagonists?

Can you mix nitrofurantoin and levofloxacin or are they antagonists?

You *may*, but. ..: The only time I would see using these at the same time is in the unfortunate circumstance that you were treating a urinary tract infection with the nitrofurantoin and a different infection with the levofloxacin - a highly unlikely circumstance. There's no reason to be using the two together to be treating the same infection. When it comes to antibacterials, never ever use more than you need. ...Read more

Had a UTI and was put on Nitrofurantoin for 5 days on my last day of tablets and I feel so much better but my bladder is so weak is this normal?

Weak bladder?: I am wondering what you mean by your bladder being weak. Are you saying that you are leaking urine? It sounds like you may still have a urinary tract infection. Maybe the bacteria you have is resistant to the nitrofurantoin. I recommend you see a doctor for a recheck. ...Read more
