THYROTOXICOSIS

[dkchamoli]

i am on thyroxine sodium from the last 15 months. a month back when i was taking 100 mcg dosage, doctor raised the medicine to 150 mcg.
Now a month is passed & following thyroid levels were observed
FT3- 5.1 pg/dl ( 1.7-4.2)
FT4-2.15 ng/dl (0.7-1.8)
Suggesting Thyrotoxicosis. I dont observed any symptoms.
What i should do, either stop the medication or to go for a re-scan.
Is there anything to worry

Even though those results are over the ranges it should not be enough to be a concern.  The main consideration is how you are feeling.

Probably the best thing would be just to to back to a lower level.  What were your test results before the increase to 150 mcg?  How were you feeling at that time?

I dont remember the results but slight headache observed, when raised from 100 to 150 mcg, that too for 1-2 days. Rest is no change. Should i continue to take the medicine. Presently i have 125 mcg tablets should is it safe to take half of the tablet.

I think you should discuss with your doctor the latest test results that are over the ranges for both FT4 and FT3, and ask about decreasing your dosage back to something in between the prior dose of 100 and the 150 you were prescribed.
