Are Laxatives Safe?

April 24, 2024

Medications can be a vital part of constipation management in children. There are several different kinds of medications including stool softeners, osmotic laxatives, stimulant laxatives, and options such as suppositories and enemas. Miralax, an osmotic laxative, is one of the most common and discussed options. While these medication methods can be very beneficial with constipation management, they can also be intimidating to use with children.

What is Miralax? Miralax is a brand name for PEG-3350, or polyethylene glycol 3350 and is considered an osmotic laxative. Osmotic laxatives work by drawing and retaining fluid in the small intestine, hydrating and softening stool. It can also increase pressure to stimulate peristalsis, or muscle contractions that help move substances through our digestive tract.

Is Miralax safe to use? While it is always important to discuss medication management with a pediatrician, the short answer is yes! It's generally safe for short-term use under the guidance of your doctor. Recently, there have been non evidence-based concerns about side effects and long term use of osmotic laxatives such as Miralax. The most recent evidence shows that PEG 3350 (Miralax) does not cause autism spectrum disorders or increased levels of glycol in the body, and does not cause a dependence on osmotic laxatives with extended use. It is safe for pediatric and adult populations. Per the North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition (NASPGHAN), there is no evidence to support serious adverse effects. 

With this in mind, it is also important to acknowledge that every child is different, and personalized management is important. As stated above, there are many different types of laxatives and pharmaceutical supports that can be utilized for constipation. We understand that it can be difficult to get children to take laxatives, and you may not want to use them long term. While it is important to utilize a bowel maintenance program, any concerns or preferences you have should be addressed and prioritized with your pelvic floor physical therapist and pediatrician.
