Olopatadine was found not to be teratogenic in rats and rabbits. There are, however, no adequate and well controlled studies in pregnant women. This drug should be used in pregnant women only if the potential benefit justifies the potential risk to the fetus.

Nevertheless, caution should be exercised when administered to a nursing mother.
