Mineral Oil for Constipation in Babies

Constipation can result in hard, dry stools that are difficult for a baby to pass 1. When looking for a remedy to improve baby constipation, many parents turn to time-tested mineral oil 13. This readily available, over-the-counter laxative works by forming a coat over the intestinal surface that prevents water absorption. Although mineral oil is an effective adult constipation remedy, it is not appropriate for infants 13. Giving your infant too much mineral oil can result in an overdose, which can have serious health consequences 35.


Doctors do not recommend mineral oil for children under the age of six due to concerns about their safety and efficacy in this age group, according to the Drugs.com database, doctors 3. Since it is a hydrocarbon made of distilled petroleum, pediatrician William Sears, the author of “The Family Nutrition Book” also expresses concerns about mineral oil ingestion by infants 3. If your baby consumes too much mineral oil, seek immediate emergency attention 3. Your baby might need activated charcoal, breathing support or IV therapy to treat the symptoms of a mineral oil overdose 35.
