Thanks for query,
What I feel is before starting the thyroid
treatment you might have undergone another thyroid tests to to confirm hypothyroid.
I suggest you to go for T3,T4 test for confirmation.
Now consult your doctor and discuss this and go for the treatment selecting proper dosage schedule.
With maintenance dose you continue the treatment for some time and then go for the test and continue or discontinue the medicine after your doctor advice
Ok and bye.
