Urinary Tract Infections in Children
Medications
Oral antibiotic medicine usually is effective in treating urinary tract infections (UTIs). In many cases, if the symptoms and urinalysis suggest a UTI, the doctor will start medicine without waiting for the results of a urine culture.
Antibiotic treatment for a UTI in a child typically lasts 7 to 14 days. A shorter course of antibiotics is sometimes appropriate in older children.
The doctor may give intravenous (IV) antibiotics if your baby is:
- Younger than 2 to 3 months.
- Too ill or nauseated to take oral medicine.
- Very sick with a severe kidney infection.
The doctor will stop the IV medicine and begin oral medicine treatment after your child is stabilized and feeling better.
Preventive antibiotics
To prevent kidney damage that can result from recurrent infection, the doctor may prescribe long-term treatment with antibiotics for children who are at risk for repeated infections. The doctor may consider preventive antibiotics:
- While waiting for the results of tests done after treatment for a child's first UTI.
- If tests done after treatment for a child's first UTI reveal a structural problem with the urinary tract, such as vesicoureteral reflux, that increases the child's risk for recurrent UTIs.
- For children who have frequent UTIs, with or without an abnormality of the urinary tract.
Preventive treatment may last from several months to several years. Experts disagree about the best approach. Some doctors believe that long-term use of low-dose antibiotics can safely prevent UTIs in children.5 However, their long-term effects need more study. Some doctors are becoming more hesitant about prescribing antibiotics for long-term use because of increasing concern about the growth of antibiotic-resistant bacteria.
Medication Choices
Medicines that treat UTIs in children include antibiotics to kill the bacteria that cause UTIs.
What To Think About
Give your child all of the antibiotics that the doctor prescribes. Your child may begin to feel better soon after starting the medicine. But if you stop giving your child the medicine too soon, the infection may return or get worse. More importantly, not taking the full course of antibiotics encourages the development of bacteria that are resistant to antibiotics. This makes antibiotics less effective and future bacterial infections more difficult to treat.
