beta blockers and thyroid

[fiftyone]

Is there some relationship between beta blockers and thyroid function?

[SlowDragon Administrator]

Depends which beta blocker

Have you had vitamins and thyroid antibodies tested yet?

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 you have autoimmune thyroid disease (Hashimoto's) diagnosed by raised Thyroid antibodies

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).

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

Propranolol inhibits Ft4 to Ft3 conversion so may require increase in levothyroxine. I donknow about other betablockers.

This is an extract fom an article of how medications can affect Thyroid function .

Beta blockers and corticosteroids that only inhibit the peripheral conversion of T4 to T3 interfere minimally with thyroid function test results. Propranolol hydrochloride (>160 mg/d), atenolol, and metoprolol tartrate produce small reductions in total T3 levels. Large doses of corticosteroids (for example, >4 mg dexamethasone) produce reductions in total T3 levels, which are useful in the management of thyroid storm or severe hyperthyroidism.
