From the Research
For a 3-year-old female, the recommended dose of MiraLAX (polyethylene glycol 3350) is typically 1/2 to 1 teaspoon (2.5-5 grams) mixed in 4-8 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.
- The medication usually takes 24-48 hours to work.
- MiraLAX works by drawing water into the colon to soften stool and increase bowel movements.
- It's essential to ensure adequate fluid intake while using this medication.
- If constipation persists beyond two weeks of treatment, consult a healthcare provider.
- Also, watch for signs of dehydration such as decreased urination, dry mouth, or unusual tiredness.
- MiraLAX is generally considered safe for short-term use in children, but long-term use should be supervised by a healthcare provider.
- Always measure using the provided cap or a measuring spoon, not a regular household spoon, to ensure accurate dosing.
Supporting Evidence
- A study published in 2016 in the Revista espanola de enfermedades digestivas found that polyethylene glycol with or without electrolytes is more efficacious than placebo for the treatment of functional constipation, either in adults or in pediatric patients, with great safety and tolerability 1.
- Another study published in 2013 in the Minerva gastroenterologica e dietologica found that the combination of psyllium and polyethylene glycol could combine the advantages of fiber and isotonic solutions and represent an important therapeutic option for patients suffering from chronic constipation 2.
Important Notes
- The provided evidence does not directly address the dosage for a 3-year-old female, but the recommended dose is based on general guidelines and expert opinion.
- It's crucial to consult a healthcare provider if constipation persists or worsens despite treatment.
- Long-term use of MiraLAX should be supervised by a healthcare provider to minimize potential risks and ensure optimal treatment outcomes.
