If GBS status is unknown, antibiotic prophylaxis is recommended during preterm labor and delivery (less than 37 weeks), in the presence of maternal fever during labor, or with prolonged rupture of membranes (greater than 18 hours)[2].

What is considered adequate treatment for GBS?

The recommended antibiotic for intrapartum GBS prophylaxis is penicillin, although ampicillin is an acceptable alternative. The dosing regimen for penicillin G should be 5 million units intravenously, followed by 2.5 to 3.0 million units intravenously every four hours.

When is GBS treated pregnancy?

Treatment works best when it begins at least 4 hours before childbirth. If you have GBS and you're having a scheduled cesarean birth (c-section) before labor starts and before your water breaks, you probably don't need antibiotics. It's not helpful to take oral antibiotics before labor to treat GBS.
