Side Effects of Long-Term Use of Miralax in Children

Miralax is an over-the-counter laxative for children and adults with occasional constipation. It is not recommended for long-term use, and any use for longer than 7 days should be approved by a doctor. Doctors often recommend Miralax for children with constipation, but some parents have begun to question if long-term use causes serious side effects. The generic name for Miralax is polyethylene glycol 3350.

History

• Schering-Plough Corporation (SGP) originally introduced Miralax as a colon cleanse for patients undergoing colonoscopy. They then began to offer it for use as a prescription laxative for treatment of occasional constipation. In 2007, prescription-strength Miralax became available as an over-the-counter medication.

Function

• Miralax helps to alleviate occasional constipation. It works to stimulate more frequent bowel movements by pulling water in the digestive tract.

Side Effects of Short-Term Use

• Short-term use of Miralax can cause minor side effects such as gas, nausea, bloating and cramping. Possible serious side effects include severe diarrhea, bloody stools and severe stomach pain.

Side Effects of Long-Term Use

• Anecdotal stories suggest a range of side effects of long-term use of Miralax including arthritis, tremors and personality changes. Conversely, a research study published in 2007 found no serious side effects with long-term use of Miralax.

Warning

• Miralax should not be used if you are allergic to polyethylene glycol or have an intestinal blockage. If you have kidney disease, you should use Miralax only under a doctor's supervision.
