Issues with Desiccated Thyroid ERFA Medication

[ELKA49]

Ever since August 2024, I have experienced having issues taking the Desiccated Thyroid ERFA medication. When I take the medication I have side effects of anaphylactic type symptoms of throat closing up, hard time breathing and blood vessels constricting and legs swelling up , as well as having a migraine. I used to take 75 mg in 30 mg tablets and the lot numbers for the medication are LF30974A and LF30976A.

Has anyone else experienced similar symptoms, I had been taking the desiccated thyroid ERFA medication for 12 years without having any side effects but it seems that something has changed with the medication batches since August 2024 to December 2024 as the medication now seems to have side effects?

It could be allergy to some excipient. Allergies on basically everything can develop at any time of life, you don't need to be born with it. For example I am allergic to artificial sweeteners, this started several years ago. Before that I was able to drink gallons of drinks with it and nothing. Now if I take just a sip I feel like I'm dying.

I am also on erfa and its not working for me now. I noticed this with my November 2024 prescription all my low thyroid symptoms are coming back shortness of breath tight chest and horrible coughing whenever I try to eat anything. I have never tried synthroid and have heard awful things about it
