Dr. Grief, I have Graves Disease and am on the prescription Liothyronine sodium 25 mcg tablets, once in the am on an empty stomach. I had my thyroid ablated in 2001, I am 75 years old. I need to be on these meds as I need to keep my thyroid level stable. I paid $35 in October, 2013 for 180 pills, for 3 months. the prescription will now cost me $116.03 for the same meds. I can't afford this. Do you have any suggestions for substitutions for me? thank you........Barbara Volkman
