Brief Answer:
You need to decrease the dose

Detailed Answer:
Hi XXXXXX,

Welcome to HCM. I had gone through your question and understand your concerns.

Once on treatment the target TSH is usually kept between 0.5 and 4 miu/ml at your age. So now the TSH is below this target and you need to decrease the dose. In a similar case I would have decreased the dose to 125 mcg of thyronorm per day and repeated the TSH after 2-3 months.

Hope I have answered your question. If you have any further questions I will be happy to help.
