Hello helpful people

Just been to pharmacist at GP, unable to actually see a GP of course, been told I have high blood pressure and may need medication. However my recent blood test showed I was prescribed too much levo. Is there a connection. I am 79 years young. I have been advised to lower levo..I'm on quite low dose anyway...to 50 Mon-~Fri and 75 Sat/Sun.

Many thanks for your time

I would want to see ACTUAL thyroid results first before lowering Levo

High blood pressure is often a hypothyroid symptom

Or is nothing to do with thyroid

How long have you been on just 50mcg and 75mcg twice week

what vitamin supplements are you taking

When were vitamin levels last tested

I don't really think it works like that.

You can be over-medicated, but if you're hypo, you can't suddenly become hyper.

To know if you're over-medicated, you need a suppressed TSH, over-range FT4 and very over-range FT3. Have you seen your blood test results? Do you have a copy? If so, post the results on here with the ranges, and let's have a look.

Even if you were over-medicated, it would not give you high blood pressure permenantly. It would come down when you lowered your dose, and you would not have to take medication for it.

But, did you know that high blood pressure can be a symptom of under-medication? And, on such a low dose of levo, I wouldn't be at all surprised if you were under-medicated. :)

What do you mean by “overdose of levothyroxine “

Bloods should be retested 6-8 weeks after each dose change or brand change in levothyroxine

For full Thyroid evaluation you need TSH, FT4 and FT3 tested

Also both TPO and TG thyroid antibodies tested at least once

Very important to test vitamin D, folate, ferritin and B12 at least once year minimum

About 90% of primary hypothyroidism is autoimmune thyroid disease, usually diagnosed by high thyroid antibodies

Autoimmune thyroid disease with goitre is Hashimoto’s

Autoimmune thyroid disease without goitre is Ord’s thyroiditis.

Both are autoimmune and generally called Hashimoto’s.

Low vitamin levels are extremely common when hypothyroid, especially with autoimmune thyroid disease

20% of autoimmune thyroid patients never have high thyroid antibodies and ultrasound scan of thyroid can get diagnosis

In U.K. medics hardly ever refer to autoimmune thyroid disease as Hashimoto’s (or Ord’s thyroiditis)

Recommended that all thyroid blood tests early morning, ideally just before 9am, only drink water between waking and test and last dose levothyroxine 24 hours before test

This gives highest TSH, lowest FT4 and most consistent results. (Patient to patient tip)

Private tests are available as NHS currently rarely tests Ft3 or all relevant vitamins
