have you been on any thyroid medication before? Or is this 135 mcg T4 medication the first you've taken?
How long have you been on this dosage
T4 medication takes up to 6 weeks to stabilize in the blood stream. So if you've been taking less than 4 weeks you are likely to not feel anything.
or if you do feel anything you may actually feel WORSE for a short time. Especially if this is an inital dosage
which would be a HUGE starter dose.
