UTIs are treated with antibiotics. If your health care provider thinks your child has a UTI, he or she will choose a drug that treats the bacteria most likely to be causing the problem. Sometimes a few days later, after your health care provider has the urine culture results, the antibiotic might be changed to one that works better against the type of bacteria that was found in your child's urine. You can also help your child fight the infection by encouraging him or her to drink plenty of fluids and urinate often.
The antibiotic drug, the way it is given, and the number of days it must be taken may depend on the type of infection. If your child is very sick and not able to drink, the antibiotic may need to be given as shots with your child in the hospital. Otherwise, the meds may be given by mouth. Depending on the type of antibiotic used, your child may take a single dose per day or up to 4 doses per day. You may be asked to give your child meds until further tests are finished.
After a few doses of the antibiotic, your child may appear much better. Most UTIs are cured within a week if treated the right way, but often it may take weeks until all the symptoms are gone. It is important that your child take the antibiotic meds as ordered by your health care provider even if the symptoms have gone away. Unless UTIs are fully treated, they may return, or your child may get another infection.
If symptoms get worse or do not get better within 3 days, your child may need to go to the hospital.
