Expected Course With treatment, your fever should be gone and symptoms should be better by 48 hours after starting the antibiotic. Read the advice on preventing UTIs to decrease your risk. Try not to forget any of the doses. Take the medicine until all the pills are gone. Even though you will feel better in a few days, take the antibiotic for the full 10 days to keep the UTI from flaring up again.
Extra fluids Drink extra fluids to help clear the infection.
Medical follow-up Two days after you begin antibiotics, it is important to contact your physician to find out the results of the urine culture and make sure that your infection is responding to the antibiotic. About 2 weeks after your initial visit your physician will want to see you for another urine culture. If you are asked to bring a urine sample to your physician's office, try to collect the urine when you first urinate in the morning. Use a jar and lid that have been sterilized by boiling for 10 minutes. Start to urinate into the toilet and then place the clean container directly in line with the stream of urine.
