Appropriate use of laxatives: Mineral oil

The use of mineral oil to treat constipation has been controversial. Mineral oil softens the stool and provides lubrication for easier elimination.

Concerns that mineral oil may bind fat-soluble vitamins arose after a 1939 study that showed a decrease in serum carotene after six months of a high-dose mineral oil use. More recent studies have demonstrated no adverse effects of mineral oil use on fat-soluble vitamin status.

Mineral oil is not recommended for infants or for children with swallowing difficulties who are at risk for aspiration. Aspiration of mineral oil can lead to lipid pneumonia.

More information about mineral oil and constipation, including references to the studies around mineral oil and fat-soluble vitamin status, is found in the For More Information section and the resource packet.

Appropriate Use of Laxatives: Corn syrup

Constipation is sometimes treated with corn syrup. The theory behind its use is that the high osmolarity of corn syrup will draw more water into the intestinal tract. Research studies have not shown that liquids with high osmolarities are effective in treating constipation.

Depending on the amount of corn syrup used, it could contribute a significant amount of energy to a child’s food pattern. This should be included in a nutrition assessment.

Appropriate Use of Laxatives: Alternative remedies

Some remedies for constipation (e.g., bryonia, graphites, silica, nux vom, and sulfur) have been promoted. The safety of these for children has not been evaluated.
