I’m after some advice. Yesterday I started with a bad allergic reaction, hives, swollen lips and eyes, aching joints, nausea etc. I’ve taken antihistamine but it’s flared up again today!
I read online that apparently levothyroxine can cause a histamine response? I’ve been on it for just over 3 months now and I’m on 75mcg. Last TSH on 50mcg was 4.9 and T4 was 16.
Anyone experienced this at all?

It's not *usual to develop that sort of allergy 3 months after taking Levothyroxine unless you have had a change of brand. Is the 75mcg the same brand as the 50mcg you were taking?
Thanks yes same brand! Ended up being rushed to a+e tonight as couldn’t breathe, got steroids. But they’ve told me to stop my Levo and ring gp 😳😳😳 no way!
It might be better to stop the Levothyroxine just in case, at least until the steroids take effect. If it is the Levothyroxine tablets your GP can prescribe liquid Levothyroxine which won't have the fillers that are in the tablets.
I was sick for over a year and they refused my medication twice, only that I demanded an endocrine review and endocrine told GP I needed thyroxine. I’ve read that it’s the synthetic hormone in the medication that causes certain proteins to breakdown and cause histamine release in the body?
