Use in pregnancy: Pregnancy Category B: The safety of meropenem in human pregnancy has not been evaluated. Animal studies have not shown any adverse effect on the developing fetus. The only adverse effect observed in animal reproductive studies was an increased incidence of abortion in monkeys at 13 times the expected exposure in man. Meropenem should not be used in pregnancy unless the potential benefit justifies the potential risk to the fetus. In every case, it should be used under the direct supervision of the physician.
Use in lactation: Meropenem is detectable at very low concentrations in animal breast milk. Meropenem should not be used in breastfeeding women unless the potential benefit justifies the potential risk to neonates.
