Why are you sure the hives started from the thyroid med? Is it possible that the cause for being on Levo and Synthroid was that you were diagnosed with Hashimoto's Thyroiditis, with which the autoimmune system erroneously identifies the thyroid gland as foreign to the body and produces antibodies to attack and eventually destroy the gland? If so, Hashi's antibodies have been identified as causing something referred to as Hashi's rash.
The fact that you still have hives 2 years after stopping the thyroid med seems to indicate it was not related to that. What other symptoms do you have, if any? Do you have thyroid related test results from prior tests that you can post, along with reference ranges?
How long after stopping the synthroid before your hives stopped? My dr also doesnt believe its that but I never had anything like this till the Synthroid, I have been off for 3 weeks and they got worse after almost being gone!
If you use this site and search for Hashi's rash you will find numerous references to a rash that seemed to be due to the antibodies of Hashi's. I can't recall all the actions taken by various people, but I do know that taking a moderate dose of selenium has been proven to reduce levels of the antibodies, which should have a beneficial effect. Perhaps other members will have additional suggestions to help get relief.
I was recently diagnosed with Hashimoto's Disease and took Levothyroxine for two months. At the end of the second month I broke out in hives. I told my DR I thought it was the medication and he said he thinks it was something I ate also. I didn't change my daily routine. The only thing that was new was the medication. I have stopped taking Levothyroxine and now take Thyroid Assist. I do not feel like I have to take four hour naps anymore and I lost 13 pounds. I am approaching the end of my 3rd week with hives. Does anyone know how long it takes until they go away. I am frustrated.
