Itching skin: I am also on thyroid medication... - Thyroid UK
Itching skin
Have you tried taking one anti-histamine tablet one hour before you take your thyroid hormones.
If you try this and it relieves your itchiness ask whoever gives you the thyroid hormones if they have another make. It could be the fillers/binders in yours that may be the cause.

Presumably you have Hashimoto’s
First step is to get FULL Thyroid and vitamin testing,
For full Thyroid evaluation you need TSH, FT4 and FT3 (plus both TPO and TG thyroid antibodies if not been tested.) Also EXTREMELY important to test vitamin D, folate, ferritin and B12
What vitamin supplements are you currently taking
Low vitamin levels are extremely common, especially if you have autoimmune thyroid disease (Hashimoto's) diagnosed by raised Thyroid antibodies
Ask GP to test vitamin levels
Recommended on here that all thyroid blood tests should ideally be done as early as possible in morning and before eating or drinking anything other than water .
Last dose of Levothyroxine 24 hours prior to blood test. (taking delayed dose immediately after blood draw).
This gives highest TSH, lowest FT4 and most consistent results. (Patient to patient tip)
Is this how you do your tests?
Private tests are available as NHS currently rarely tests Ft3 or thyroid antibodies or all relevant vitamins

If TPO or TG thyroid antibodies are high this is usually due to Hashimoto’s (commonly known in UK as autoimmune thyroid disease).
About 90% of all primary hypothyroidism in Uk is due to Hashimoto’s. Low vitamin levels are particularly common with Hashimoto’s. Gluten intolerance is often a hidden issue to.

When adequately treated, TSH will often be well below one. Most important results are ALWAYS Ft3 followed by Ft4. When adequately treated Ft4 is usually in top third of range and Ft3 at least 60% through range (regardless of how low TSH is)
Extremely important to have optimal vitamin levels too as this helps reduce symptoms and improve how levothyroxine works
Come back with new post once you get results
I had this on both my forearms some years ago, it was unbearable as the itch didn't stop even when I scratched it raw, mine was Dermatitis herpetiformis which is linked to autoimmune reaction to gluten, could be the medication woke up your immune system a bit. I used capsicum cream on it, was the only thing that worked at the time, I had it for about 3 years on and off then it went away. I avoid gluten now BTW
