My daughter is 15, and received RAI in July of 2010. We have yet to ‘normalize’ her levels, but are increasing the synthroid just about every 4 weeks. She is currently taking 125 micrograms daily. She remains hypo, with weight gain her biggest challenge. Our pediatric endocrinologist stated it could be 5-7 months before her levels return to ‘normal’ – which is something we have not had in almost 3 years. Continued success and recovery. Rick
