T3 brand changes could this be causing awful symptoms?

I changed brand from Mercury Pharma to Morningside, I have been taking just under 10mcg T3 and 75mcg Levothyroxine for maybe 3 - 4 years now and have been really well with this. 10 days after taking the Morningside I started with achy legs then really bad indegestion which is giving me cardiac symptoms and achy arms. It hasn't been very nice. Started back on the mercury pharma yesterday still awful indegestion last night and just taken about 7 or 8 mcg now. I'm thinking give the T3 a few days to settle and if still not feeling right go the docs incase it is cardiac but won't go now incase they blame it on the T3 and take me off it. Do you think changing brand can do this?

Cardiac type symptoms is indegestion so burping all of the time then stomach pain and just uncomfortable around my chest. What isn't helpful is because of the indegestion I Darn't eat and so have an empty stomach I am trying to eat but with very sensible things.

They are certainly very different. Some prefer Morningside others don't get along with it at all

If you don't feel any better you should get checked out by doctor on Monday, or earlier perhaps

In the main the view seems to be that Morningside is stronger.

ssarahstellar,

Tell your pharmacist that Morningside doesn't suit and you want Mercury Pharma T3 dispensed in future. If pharmacist won't order the MP for you ask for your prescription form back and take it elsewhere.
