GBS prophylaxis penicillin allergy alternative?

• A. Ampicillin with appropriate precautions
• B. Penicillin G during labor
• C. Erythromycin
• D. Clindamycin

Answer: (A)

Intrapartum antibiotic prophylaxis for GBS aims to prevent neonatal GBS infection by giving antibiotics during labor. Penicillin G is the first-line choice, but when the mother has a penicillin allergy, an alternative must be used that still effectively covers GBS and can be given safely with careful monitoring. Ampicillin, although also a beta-lactam like penicillin, is considered a suitable alternative in many scenarios where the allergy history is not severe (non-anaphylactic) or when precautions are in place. Using ampicillin with appropriate precautions means confirming the allergy history, having resuscitation ready, and monitoring for any reaction during administration. This makes it a practical alternative option for GBS prophylaxis in the setting of penicillin allergy. Penicillin G during labor is not appropriate for someone with a penicillin allergy. Erythromycin and clindamycin can be used in certain circumstances, particularly if the GBS strain is susceptible to them and the allergy profile supports their use, but rising resistance and reliability concerns limit their universal applicability as a default choice in this context.
