What is mineral oil, and what is it used for?

Mineral oil is a liquid lubricant laxative available over the counter (OTC) taken orally to relieve occasional constipation. Mineral oil is a purified petroleum product and is not well-absorbed systemically.

Mineral oil reduces the absorption of water from fecal matter in the colon, softening and lubricating the stool, making it easier to pass. Oral mineral oil typically produces a bowel movement in six to eight hours. Mineral oil may also be administered as a rectal enema.


  • Do not take if you are hypersensitive to mineral oil or any of its components.
