Do Daily Antibiotics Cause My Child To Become Immune?

George F. Steinhardt, M.D., F.A.A.P., F.A.C.S.
Member, Society of Pediatric Urology

One of the most frequently asked question of parents when their child is placed on a daily antibiotic for prophylaxis, is won't my child become immune to the antibiotic? The short answer to this question is no.

In our practice, when a child is placed on antibiotics, it is usually to prevent urinary tract infections. These prophylactic antibiotics are half the dose of antibiotics prescribed to treat an infection. Unfortunately, children with risk factors for infection still may get an infection while on the antibiotic. This does not mean that the medicine is not working. It actually means the opposite; the medication is working.

When we send out urine for a culture, the lab smears a small specimen of the urine onto a special dish and watches for bacterial growth over 48 hours. At that forty-eight hour mark, the lab technician tests antibiotics on the bacteria that grew to see if it would kill it. This is how we know that certain antibiotics work on certain infections, but not all antibiotics are good for every infection. When a child is diagnosed with an infection and is on antibiotics, it means that the bacteria that grew is resistant (or immune) to that particular antibiotic. The child is not immune to the antibiotic the bacteria is.
