The usual recommended treatment for urinary infection in children is oral antibiotics and home care, according to WebMD. For children younger than three months who have weak immune systems or are too nauseated to take oral medications, injection antibiotics are another option. While at home, caregivers should encourage the child to drink a lot of liquids and urinate often, recommends the Urology Care Foundation.
Some of the antibiotics doctors prescribe to treat urinary tract infection in children are amoxicillin, cefixime and cephalexin, reports WebMD. These antibiotics come in liquid or pill form, though the doctor may give them as an injection or intravenously if the child is very ill or has a severe kidney infection.
Doctors often begin treating the urinary tract infection based on the results of a urinalysis as they wait for results of the urine culture, reports WebMD. Depending on the results of the urine culture, they may switch to a different antibiotic that targets the specific bacteria causing the urinary infection, states the National Institute of Diabetes and Digestive and Kidney Diseases.
The course of antibiotics lasts for a minimum of three to five days or for several weeks in some cases, according to the National Institute of Diabetes and Digestive and Kidney Diseases. If the infection causes pain, the doctor may also prescribe pain relief medication. Caregivers can also place a heating pad on the abdomen or back of the child to help alleviate this pain.
