Kayexalate is a type of medicated enema used to treat clients with dangerously high serum po-tassium levels. This drug contains a resin that exchanges sodium ions for potassium ions in the large intestine. Kayexalate enemas are not used to treat or prevent constipation, and Kayexalate is not a diarrheal medication. Neomycin enemas, not Kayexalate enemas, may be used to reduce bacteria in the colon before diagnostic testing.
