Hello, thanks for the query. I have seen the details mentioned. Usually when treatment is started it is always better to start with a slight lower dosage and then build as needed. Any way, since now tsh has gone very low, there is a need to reduce the present dosage of levothyroxine by at least 25 mcg to 75 mcg per day. Then check tsh after 6 weeks to whether level has come up to the expected level of 3 to 4 mu/l. If you have any questions please do come back. Thanks.
