Your child will take antibiotics for a urinary tract infection. Give this medicine to your child as your doctor says. Do not stop it just because your child feels better. He or she needs to take all the medicine to get better. The number of days a child will need to take the medicine depends on the illness, the child's age, and the type of antibiotic.
You can help your child get better at home. Have your child drink extra fluids to flush out the germs. Remind your older child to go to the bathroom often and to empty the bladder each time.
Call the doctor if your child isn't feeling better within 2 days after starting the medicine. Your doctor may give your child a different medicine. It is important to treat urinary infections quickly in children to prevent other serious health problems. Sometimes a baby younger than 3 months may need to get medicine through a vein (IV) and stay in the hospital for a while. A child who is too sick to take medicine by mouth or has trouble fighting infections also may need to stay in the hospital.
