Hi Bev, might be the generic but is might also be the amount that is in it.
I suggest asking doc for a script that says DAW or dispense as written and
write synthroid.
I am on synthroid and well that hppened to me getting generic.  Found that I
also needed a smaller doseage.  I am still on generic so who knows this.

the anxiety might be due to worrying about this also but if you have the
shakiness that can be too much thyroid.

What is the dose and what was your TSH as well as T4 and T7?

check your bp too, that is all into this.
do you take it morning and ON an empty tummy? I was told a must to do

let me know,

janers

Doc gave me a Rx for Synthroid which was filled with a generic. I'm not sure
if I should just wait through the side effects or call the doc and ask for a
new Rx. The printout that comes with it says that side effects tend to
subside over time. Within seconds of taking it I get itchy. No rash just an
itchiness on the extremities (fingers, toes, nose, ears and scalp) for about
an hour, then later on my whole body tends to feel a little itchy. Also it
seems my anxiety levels have increased. And I've also had some dizziness.
But I feel much better, lots more energy and in general I feel better
but...... What the heck is happening?
