Antibiotics for Prophylaxis in the Setting of Preterm Prelabor Rupture of Membranes.

"For many years, providers have been using antibiotics to prevent infection in women who present with preterm prelabor rupture of membranes (PPROM). Given the polymicrobial nature of intra-amniotic infection, the recommended regimen includes a 7-day course of ampicillin and erythromycin, although many substitute of azithromycin. This regimen is used from viability to 34 weeks, independent of the number of fetuses present. Meta-analyses have shown that antibiotics for this indication are associated with lower rates of maternal and fetal infection, as well as longer pregnancy latency. Thus, latency antibiotics are recommended for all women with PPROM through 34 weeks of gestation."
