lybrate-user, Thanks for the query.
Since you are on treatment with levothyroxine
for hypothyroidism, it is necessary to maintain TSH level around 3 to 4 mU/L, to be free from all the troublesome symptoms of that condition. TSH level of 23 mU/L, shows that all the symptoms will be fully back, secondly the dose being taken is not adequate at all. You will have to increase the dose by 25 mcg, then check
TSH after 6 weeks and see if the desired level of TSH is achieved. If not then there has to be further increase in the dose. Thanks.
