From the Research
For a 3-year-old child, the typical Miralax (polyethylene glycol 3350) dosage is 1/2 to 1 teaspoon (2-4 grams) mixed in 4 ounces of liquid once daily, as supported by the most recent and highest quality study 1. This dosage is recommended based on the child's response, and it is essential to start with the lower dose and adjust as needed. Miralax works by drawing water into the intestines to soften stool and make it easier to pass, typically taking 24-48 hours to see results. Some key points to consider when administering Miralax to a 3-year-old child include:
- Mixing the powder completely in water, juice, or another beverage the child enjoys, and ensuring they drink the entire amount.
- Consulting the child's pediatrician before starting Miralax, as they may recommend a specific dose based on the child's weight and constipation severity.
- Ensuring the child drinks plenty of fluids throughout the day and eats fiber-rich foods to help prevent future constipation. It is also important to note that Miralax is generally considered safe for children when used as directed, but if constipation persists after several days of treatment, it is crucial to contact the doctor. The most recent study 1 provides good evidence to recommend polyethylene glycol as a first-line laxative, and it is essential to follow the recommended dosage and administration guidelines to ensure the best possible outcome for the child. Additionally, other studies 2, 3, 4, 5 provide supporting evidence for the use of Miralax in treating constipation, but the most recent and highest quality study 1 should be prioritized when making a recommendation.
