Neomercazole is a brand of carbimazole used to treat Graves' disease (hyperthyroid)

Presumably you have Hashimoto's (hypothyroidism) which can have temporary hyperthyroid type flares, when thyroid gland dumps a load of hormones in blood

You need to know exactly what has been tested and get Thyroid TSH, FT3 and FT4 retested and vitamin levels tested

If you only have Hashimoto's you probably should not be on carbimazole

It is possible to have Hashimoto's and Graves at same time

You need to know EXACTLY what has been tested. You are legally entitled to printed copies of your blood test results and ranges

TPO and TG thyroid antibodies, (can be present in both Graves or Hashimoto's) Essential to test TSI or TRab antibodies as these are only present with Graves

For full Thyroid evaluation you need TSH, FT4 and FT3 plus both TPO and TG thyroid antibodies tested. Also extremely important to test vitamin D, folate, ferritin and B12

Low vitamin levels are extremely common, especially if Thyroid antibodies are raised

All thyroid blood tests should ideally be done as early as possible in morning and fasting. Do not take Levothyroxine dose in the 24 hours prior to test, delay and take immediately after blood draw. This gives highest TSH, lowest FT4 and most consistent results. (Patient to patient tip, best not mentioned to GP or phlebotomist)

Private tests are available. Thousands on here forced to do this as NHS often refuses to test FT3 or antibodies

Medichecks Thyroid plus ultra vitamin or Blue Horizon Thyroid plus eleven are the most popular choice. DIY finger prick test or option to pay extra for private blood draw. Both companies often have special offers, Medichecks usually have offers on Thursdays, Blue Horizon its more random

Private testing for suspected Graves - TSI or TRab antibodies

SlowDragon is right. Your doctor should know that if you are hypo, you cannot 'go hyper', it is a physical impossibility. If you are having a Hashi's 'hyper' swing, and taking carbimazole, you have probably gone back to being very hypo, now.

But, what were you taking before that, how much? How long have you been on the carbimazole? I think you need to see another doctor, one that knows something about thyroid.

I expect GreyGoose and SlowDragon are wondering why you haven't answered Hope you are OK ...
