Ok guys. So I found it weird that someone posted about this is the Q&A right when I saw this substance in my house. I just noticed my wifes prescription of 15mg of this stuff. I was wondering what it is prescribed for other than hypothyroidism? if anything. She has not told me why she needs it, as I have not asked her because I just found it and she is in bed. After reading 405s post, this has me worried pretty bad. Can anyone tell me about htis stuff? The internet really isnt helping when I am searching it. Thanks you guys.
