Hello and welcome to HCM.
Thank you for your query.
You have been diagnosed with a UTI, and thus been prescribed the antibiotic to treat it as well. But I am sure you knew this already.
The white substance you see in your urine is normally seen in patients diagnosed with a UTI, this is most probably pus produced due to the infection.
Now, as the antibiotics start working it should start providing you significant amount of relief from your symptoms, but not result in an increased urge to urinate. You will also require plenty of water, even cranberry juice, and a potassium chloride
based solution which will help in neutralizing the effect of the infection and provide symptom relief.
If the right antibiotic is prescribed, patients usually find significant improvement within 24 hours of initiation of treatment. How to find out if your antibiotic is the right one?
A. Urine culture examination (takes 24-48 hours). This test not only confirms the infection, but also identifies the infection-causing organism and provide information on the most suitable antibiotic that can be used to treat you (specifically).
If you do not experience relief within 48 hours of initiation of therapy, it is best to re-visit your doctor and request for a urine culture examination and simultaneously a change in antibiotic.
