Kaolin + Pectin

What is kaolin + pectin?

Kaolin + pectin (brand names: Kaopectolin®, Kao-Pec®, KaoPect®, Kao-Pront®, Kaogel®) is a gastrointestinal protectant that is used to treat diarrhea and certain toxicities.

Its use in cats, dogs, horses, birdsferrets and other small mammals to treat diarrhea is off label (extra label). Many drugs are commonly prescribed for off-label use in veterinary medicine. “Off label” means the drug is being used in a way that has not been reviewed or approved by the U.S. Food and Drug Administration (FDA) or Health Canada. In these instances, follow your veterinarian’s directions and cautions carefully, as they may be significantly different from those on the label.

How is kaolin + pectin given?

  • Kaolin + pectin is given by mouth in the form of a liquid suspension.
  • It may be given with or without food; however, if vomiting occurs when dosed on an empty stomach, give future doses with food.
  • Measure liquids carefully and shake well before using.

This medication should take effect within 1 to 2 days, and improvements in clinical signs should follow.

What if I miss giving my pet the medication?

If you miss a dose, give it as soon as you remember, but if it is closer than 12 hours until the next scheduled dose, either:

  • Skip the dose you missed, give it at the next scheduled time, and continue with the regular dosing schedule, or
  • Give the missed dose and then wait the recommended interval before giving the next dose (continue giving it regularly at that new time).

Are there any potential side effects?

Kaolin + pectin may cause the following side effects:

  • Constipation (rare)

Serious adverse reactions may occur. If any of the following signs develop, stop giving kaolin + pectin and contact your veterinarian immediately:

  • Fever
  • Tiredness
  • Lack of appetite
  • Inability to have a bowel movement

This short-acting medication should stop working within 24 hours, although effects can be longer in pets with liver or kidney disease.

Are there any risk factors for this medication?

DO NOT USE kaolin + pectin in:

  • Pets that are allergic to it
  • Pets with diarrhea that is caused by an infection or to treat severe diarrhea

USE WITH CAUTION in:

  • Trimethoprim + sulfa

Be sure to tell your veterinarian about any medications (including vitamins, supplements, or herbal therapies) that your pet is taking before starting any new treatment.

Is any monitoring needed with this medication?

  • Your veterinarian will let you know when and how they want to reassess your pet to ensure the medication is working and not causing side effects.
  • When diarrhea is severe, fluid and electrolyte balance should be monitored.
  • At home, monitor for any side effects such as those noted above. If any occur, stop using the medication and contact your veterinarian.

How do I store kaolin + pectin?
