    Hello – I believe the half-life of Methimazole is fairly short (a matter of several hours).

    We are not allowed to make dosing recommendations on this board, as we are all fellow patients, not doctors.

    I would suggest calling the endo’s office and pointing out the very low T4 to get their feedback on dosing. If they won’t give you guidance over the phone, you might also check to see if they have a cancellation and if you can get in sooner. Or perhaps your primary care physician might be more responsive.

    Take care — and let us know what you hear back!
