Overview of Kaolin and Pectin for Dogs and Cats

  • Kaolin and pectin, commonly known as Kapectolin® or K-P®, is used to treat diarrhea and minor stomach problems, such as stomach inflammation (gastritis) in dogs and cats.

    The following information applies to products with the active ingredients of kaolin and pectin. Please note that the older formulation of Kaopectate® contained kaolin and pectin but this is no longer the case. If your bottle of Kaopectate® indicates that you have the formulation with bismuth subsalicylate, please click here. This is important because this change makes the new formulation of Kaopectate® no longer safe to routinely administer to cats.

  • Kaolin and pectin may provide a coating action that protects the stomach lining. There may also be additional adsorbent effects by which the coating action may prevent absorption of bacteria and toxins. Some products use an adsorbent called attapulgite in place of kaolin. The pectin component may act to decrease the pH in the intestine (increasing acidity).
  • Kaolin and pectin is available over the counter but should not be administered unless under the supervision and guidance of a veterinarian.
  • Brand Names and Other Names for Kaolin and Pectin

  • Human formulations: Kao-Spen®, Kapectolin® and K-P®. Also multiple generic preparations. Please note it used to be the active ingredient in the old formulation of “Kaopectate®” (please check bottle to determine active ingredient).
  • Veterinary formulations: There are numerous drug companies with a variety of trade names and various generic preparations. Though some are labeled for animals, it is uncertain if they are FDA approved for that purpose.
