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