From the Research
For a 2-year-old child weighing 13.7kg, the recommended dose of MiraLAX (polyethylene glycol 3350) is approximately 1/2 to 1 teaspoon (2.5-5 grams) mixed in 4 ounces of water or juice once daily, as supported by the most recent and highest quality study available 1.
Key Considerations
- Start with the lower dose and adjust as needed based on the child's response.
- MiraLAX typically works within 24-72 hours by drawing water into the colon to soften stool and increase bowel movements.
- This medication should be given for constipation only, and if symptoms persist beyond 7 days, consult your pediatrician.
- Always mix the powder completely until dissolved before giving it to your child, and ensure adequate fluid intake throughout the day.
- MiraLAX works gently by increasing water in the digestive tract rather than stimulating the intestines directly, making it generally well-tolerated in children, as noted in studies such as 2 and 3.
Safety and Efficacy
- The efficacy and safety of polyethylene glycol in children have been established in various studies, including a meta-analysis that found it to be effective and safe for chronic constipation and resolving fecal impaction in children 3.
- While other studies provide additional context on the use of polyethylene glycol in adults and its comparison with other laxatives 4, the focus for pediatric use remains on its efficacy and safety profile as an osmotic laxative.
- It is crucial to follow the recommended dosage and to consult a pediatrician if there are any concerns or if symptoms persist, as general pediatric care guidelines suggest 5.
