You should see an improvement by the 2nd to 3rd day. Uncomplicated antibiotics can be treated with only 3 days of antibiotics. Complicated UTIs that causes fever, chills blood in the urine and other symptoms are treated longer, up to 7 days.

That depends on the type of infection. Mild UTI may just need 3 days of antibiotics treatment and severe type of infection may take up to 10 days. It also depends on the type of bacterial infection.
Hope this answers your question. Thanks.
1-2 days, unless something else is going on. If infection doesn’t clear, may need sonogram.
Depends on the severity of the UTI and your age/sex and underlying urological tract disease if any. It would be one day, and could be 3 weeks of treatment depending on the above factors.
