"For women known to carry GBS where it is not expected that the intravenous antibiotics can be given for at least 4 hours before delivery, an intramuscular injection of 4.8 MU (2.9 g) of Penicillin G at about 35 weeks of pregnancy may be useful in addition to intravenous antibiotics given from the onset of labour or membranes rupturing until delivery to try to eradicate GBS carriage until after delivery". However, this recommendation IS NOT supported by any of the present guidelines.
