What is the best thyroid medication after thyroidectomy?

Patients undergoing a total thyroidectomy become hypothyroid and require lifelong therapy with thyroid hormone.

What is the maximum amount of thyroxine you can take?

Levothyroxine doses are dependent upon the person's body weight and their blood test results. Most patients require between 100 and 150mcg a day, but the dose can be lower than 50mcg or up to 300mcg a day, depending on your needs.

Will I need thyroid hormone after thyroid surgery?

What should your T4 level be with no thyroid?

A normal T3 level might be somewhere between 100 to 200 nanograms per deciliter (ng/dL), while a normal T4 level falls between 5.0 to 12.0 micrograms per deciliter (μg/dL). Free T4, which tests for the amount of T4 that is available in the body, should range between 0.8 to 1.8 nanograms per deciliter (ng/dL).

What happens if I dont take thyroxine after thyroidectomy?

Skipping or stopping your antithyroid medication or thyroid hormone replacement will lead to undesirable and possibly dangerous effects. Not taking your medication also increases your risk of fatal conditions like myxedema coma if you are hypothyroid, and thyroid storm if you are hyperthyroid.

If the TSH is not at the desired goal, the levothyroxine dose can be adjusted up or down. TSH values that are slightly out of range may be corrected by a single dose increment or decrement, such as increasing from 100 to 112 μg or decreasing from 175 to 150 μg.

What should my TSH be on levothyroxine?

It is generally recommended to aim for a TSH in the lower half of the normal range, ie, typically <2.5 mIU/L in patients with primary hypothyroidism on levothyroxine replacement.

How often should thyroid levels be checked after thyroidectomy?

A previously normal TSH level should be rechecked at least biannually in an asymptomatic patient post-thyroid lobectomy or total thyroidectomy. A previously abnormal TSH level should be rechecked in, at minimum, 7 weeks or 2 month intervals until levels stabilize.
