Give it a shot. If it works it works. If not, another potential option is Armour. It is natural thyroid as opposesd to levothyroxin which is synthetic. Unfortunately it is more expensive and harder to get in some places. My mom has been on Armour for years and it works really well for her. P.S: I'm not a doctor, so this is just my personal opinion. https://www.armourthyroid.com/
