If your baby tests positive for group B strep, he or she will be given intravenous (IV) antibiotics to destroy the bacteria. In some cases, IV fluids, oxygen or other medications, depending on your baby's condition, may be needed as well.


Antibiotics are effective treatment for group B strep infection in adults. The choice of antibiotic depends on the location and extent of the infection and your specific circumstances. If you're pregnant and develop complications due to group B strep, you'll be given oral antibiotics, usually penicillin or cephalexin, which are safe to take during pregnancy.
