Pediatric Constipation
Seeing your child suffer with constipation can be one of the hardest things for a parent to endure. Many pediatricians will continue to prescribe miralax, even if it’s no longer working. See if your child could qualify for a clinical trial of a medication already approved for use in adults. If they qualify, you will be compensated up to $1,250* for your time and travel.
