Underactive Thyroid
"Been on Synthroid for years, due to insurance mandates, was switched to Levothyroxine generics. Too many manufacture changes when I get Rx renewals.  This last time, after 2 months of experiencing intermittent and then continual eruptions of hives/intensive itching - where I would scratch myself causing bleeding during my sleep - I think I have narrowed it down to my latest Rx of this generic.  I had completed the usual routine of how to find out what was causing my hives/itching - and finally, the other day I figured it happened about the time I started my new RX.  I know it is not good, but I didn&#039;t take my levo for two days and my itching has stopped, my skin is beginning to heal.  I found an older bottle of levo and am using it."
