Description

Mineral oil is a liquid petrolatum that has been refined for internal use. Mineral oil acts as a laxative by lubricating fecal material and the intestinal mucosa. It also reduces reabsorption of water from the gastrointestinal tract, thereby increasing fecal bulk and decreasing intestinal transit time.

Some veterinarians prescribe mineral oil to clear sand from the intestinal tract in the case of sand colic. It is suggested that it be mixed with psyllium for the best results.

Usage

Mineral oil is used in horses to treat constipation and fecal impactions, and, in some cases, to treat sand colic. It is sometimes administered after an animal ingests lipid-soluble toxins, such as kerosene or metalaldehyde, to retard the absorption of these toxins through its laxative and solubility properties.

Mineral oil may also be used as a hoof dressing to protect and condition the horse's hooves when recommended by a farrier or veterinarian.

Dosage and Administration

Side Effects

Granulomatous reactions have occurred in the liver, spleen, and mesenteric lymph nodes when significant quantities of mineral oil are absorbed from the gut. Oil leakage from the anus may occur. Long-term administration of mineral oil may lead to decreased absorption of fat-soluble vitamins (A,D,E, & K).

Precautions

Oil should be administered in appropriate cases, and when tubing is used, care should be taken to make sure that the tube is in the stomach to prevent aspiration into the lungs.

Mineral oil should be given between feedings to keep it from interfering with vitamin absorption.

Interactions

None noted, except for interfering with vitamin absorption.

Overdose

No specific information is given.
