Allergic to Synthroid and Armour

[losenit]

I am a 35 year old female with hashimotos's Thyroiditis.  I have been taking synthroid for 4 years with no problems until about 2 weeks ago.  Broke out in hives.  I know it is the synthroid because right after I take it I begin itching and stinging, and now some chest tightness.. Tried Armour and am having the same problem.  Could it be an inactive ingredient in the meds?  And, if so, what other options do I have?  I have looked up all the medications available for hypothyroid and they all seem to contain the same inactive ingredients.  Getting pretty scared at this point.  Dr. says to take antihistamines before taking the synthroid, but hives are still there and I can still feel the reaction going on.  Don't know how much longer I can continue this.  Please help!

My similar symptoms dimished when I changed to Levoxyl.  I had to make that change because it was the only one my new insurance covered  It turned out to be a good thing.  I'd give that a try.

Have you had levels checked recently?

Levoxyl is free of dyes. The active ingredients are the same, but the binders and fillers usually vary. Your pharmacist may be able to help with this. It sounds like an allergic reaction.

Is your doc an endo?
