Antibiotic Linked To Intestinal Disorder In Infants

The September, 2001 issue of the Journal of Pediatrics reports that giving infants the antibiotic erythromycin, especially within the first two weeks of life, can increase their chances of developing an intestinal disorder that likely will require surgery.

The disorder, called infantile hypertrophic pyloric stenosis (IHPS), occurs when the tube leading from the stomach to the small intestine (the pyloris) becomes enlarged, blocking the stomach's outlet. This results in projectile vomiting, dehydration and weight loss. IHPS is the most common cause of abdominal surgery in infancy.

The researchers also found that there may be a link between IHPS and a mother using the antibiotic during the last 10 weeks of pregnancy as well. The study also saw some evidence that two related antibiotics, azithromycin and clarithromycin may also be linked to IHPS.
