No clinical study has been conducted in pregnant or lactating women.
Reproduction studies performed at human equivalent doses of 115 g/day in rabbits and 58 g/day in rats, (assuming a 60 kg body mass) do not indicate direct harmful effects with respect to pregnancy, embryonal/foetal development, parturition, or postnatal development. Because animal reproduction studies are not always predictive of a human response, LOKELMA should be used during pregnancy only if the potential benefit to the mother justifies any potential risks to the foetus.
Due to its physicochemical properties, sodium zirconium cyclosilicate is not systemically absorbed and is not expected to be excreted in breast milk.
