If diagnosed with a urinary tract infection (UTI), 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, such as 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. Urinary tract infections 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.
Urinating often and drinking plenty of fluids.
Preventing future UTIs
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 bacteria from the anus to the urethra.
Call your child's doctor after the child finishes taking the antibiotics. Your child may be checked to make sure the infection is gone.
When to call your doctor
Call your child's doctor right away if he or she develops:
Back or side pain
These may be signs of a possible kidney infection.
Also, call if your child has already been diagnosed with a UTI and symptoms of a bladder infection come back shortly after finishing the antibiotics. Symptoms of bladder infection include:
Blood in the urine
Foul or strong urine odor
Frequent or urgent need to urinate
General ill feeling (malaise)
Pain or burning with urination
Pressure or pain in the lower pelvis or lower back
Wetting problems after the child has been toilet trained
