Hello and welcome to HCM.
Thank you for your query.
The condition your wife is most probably suffering from is a urinary tract infection
(UTI). All the symptoms she is experiencing are related to this condition. The medications prescribed are also in accordance to this.
But, what is the most important point in treatment of this condition is the antibiotic used. A urine analysis is usually conducted to confirm the presence of an infection, this should be followed by a urine culture examination. The urine culture test helps in confirming the presence of the infection and also provides information on the most suitable antibiotic that can be used to treat the infection. Different individuals are resistant or susceptible to different antibiotics, which is why, if one antibiotic helps/works in one individual it is not necessary for the same antibiotic to work in another.
This is why, there is a possibility that your wife could be resistant to the prescribed antibiotic (Uritop-SR; which is nitrofurantoin
). Thus my advise would be to visit your doctor and request for a urine culture examination and a prompt change in the antibiotic used.
In the meantime, please keep your wife hydrated with as much water as possible; you could also give her cranberry juice which has shown to have added benefits in relieving symptoms of a UTI.
I hope I have succeeded in providing the information you were looking for. Please feel free to write back to me for any further clarifications. I would gladly help you.
