Is Kayexalate Safe in Breastfeeding

I am a breastfeeding mother and i want to know if it is safe to use Kayexalate? Is Kayexalate safe for nursing mother and child? Does Kayexalate extracts into breast milk? Does Kayexalate has any long term or short term side effects on infants? Can Kayexalate influence milk supply or can Kayexalate decrease milk supply in lactating mothers?

Because Kayexalate is not orally absorbed, it is unlikely to reach the breastmilk or adversely affect the breastfed infant after maternal administration. No special precautions are required. A suspension of Kayexalate has been added directly to breastmilk to lower the potassium concentration of milk for use in infants with renal impairment. In addition to lowering average potassium content by 65%, the calcium content of breastmilk was reduced by 84%.[1] Infants given either expressed breastmilk, formula or a combination of both had their average serum potassium levels decreased by 24% from 6.3 to 4.8 mEq/L. Serum calcium and creatinine also decreased slightly. The infants had no clinically noticeable side effects.[2] Addition of large amounts of Kayexalate to artificial formula also lowers the calcium, copper, manganese, phosphorus, sulfur and zinc concentrations; whereas the iron, sodium and sulfur content of formulas are increased.[3] Similar changes might occur with breastmilk.
