I may have developed an allergy to synthetic T3. I took Cynomel for six months and it was wonderful: then I started to itch like crazy. I thought it could have been the fillers the used in their manufacturing, so I ceased use shortly thereafter. For a while I tried working with a naturopath without any medication, but recently decided that medication was better for my overall energy. A new doctor has recently put me on another more expensive German brand (Thybon) with the same active ingredient (liothyronine/T3). It has been less than a day and the itching has returned.
Has anyone here had any similar experiences? I would love to think that this might be a temporary adjustment period while my body gets used to the medication, although I fear it's probably an allergy to Liothyronine itself since my first few months on Cynomel presented no symptoms whatsoever.
Responses are greatly appreciated.
