Ask a Doctor and Get an Answer to Your Medical Question ASAP
Good evening, I am Dr Ruff. Thank you for contacting us today. I am sorry if you have been waiting.
How long have you been taking Nitrofurantoin for? and was this used blindly to treat a UTI (i.e. without confirmation with a urine culture)? or did you grow anything on the culture?
Please note, a urine dip is not a culture, but the initial test performed to identify if infection is likely.
Hi there, thank you for your response and I am sorry for my delay.
You would normally expect improvement to occur within 24 to 48 hours so hopefully today you should be noticing if there is an improvement. Nitrofurantoin is often considered the first line antibiotic for a lower urinary tract infection so I would be suprised if symptoms did not continue.
Taking Nitrofurantoin before does not necessarily cause resistance so I would not be worried about this.
I would get a culture done, and if by day 4 there is no improvement, or your symptoms are worsening, then I would speak to your doctor about changing your antibiotics, perhaps to something like Co-Amoxiclav.
I hope this is of some help and I certainly hope your symptoms are feeling better today.
Please do feel free to let me know if there is anything else.
Best wished, Dr Ruff
My pleasure. It can increase the chance of resistance, but I would be doubtful this would cause it. Resistance with Nitrofurantoin is often found when used as a prohylactic antibiotic where it is used daily for 3-4 months at a time.
I think you will be okay. Best of luck with this, I hope you feel better soon.
I can understand your concerns.
