Symptoms of urinary tract infection (UTI) should begin to improve within 1 to 2 days in most girls. The advice below may not be as accurate for girls with more complex problems.
Treating the Infection
Your child will take antibiotic medicines by mouth at home. These may come as pills, capsules, or a liquid.
For a simple bladder infection, your child will likely take antibiotics for 3 to 5 days. If your child has a fever, your child may take antibiotics for 10 to 14 days.
Antibiotics may cause side effects. These include nausea or vomiting, diarrhea, and other symptoms. Talk to your child's doctor if you notice side effects. DO NOT stop giving the medicine until you have spoken to a doctor.
Your child should finish all the antibiotic medicine, even if symptoms go away. UTIs that are not well-treated can cause kidney damage.
Other treatments include:
Taking medicine to ease pain when urinating. This medicine makes the urine a red or orange color. Your child will still need to take antibiotics while taking the pain medicine.
Drinking plenty of fluids.
Preventing Future UTIs
The following steps can help prevent UTIs in girls:
Avoid giving your child bubble baths.
Have your child wear loose-fitting clothing and cotton underwear.
Keep your child's genital area clean.
Teach your child to urinate several times a day.
Teach your child to wipe the genital area from front to back after using the bathroom. This can help reduce the chance of spreading germs from the anus to the urethra.
