The safety of Omicap in human pregnancy has not been established. It should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
It is not known whether omeprazole is excreted in human milk. Because of the potential for serious adverse reactions in nursing infants from omeprazole and because of the potential for tumorigenicity shown for omeprazole in rat carcinogenic studies, a decision should be made whether to discontinue nursing or to discontinue omeprazole, taking into account the importance of the drug to the mother.
