In brief: Yes

Tapazole (methimazole) is used to stop the thyroid from overproducing thyroid hormone.
It is typicaly used in the treatment of graves disease. Unless the autoimmune problem that is causing his thyroid to overproduce has resolved, if he stops the tapazole (methimazole) the thyroid level is likely to become high again. He needs to talk to his doctor about whether it is time to try to stop the tapazole (methimazole).

In brief: Yes and no

Yes, he still needs treatment, but depending on how long he has been on his current dose, it may need to be changed.
If he has only been on tapazole (methimazole) for a short period of time, it is reasonable to continue on the same dose and recheck in a few weeks because it takes longer for the TSH to normalize than the T4 and t3. If he has been on this dose for a few months, it may be time to increase it.

In brief: TSH still too high

His TSH still indicates his level of thyroid hormone is too high.
He should definitely not stop his methimazole, and his doctor should consider increasing it if TSH remains suppressed. Depending upon age, it is likely he will need this medication for life, unless a more definitive therapy such as i-131 is administered.
