Oh, sorry, more information - I'm hyper, doctor is 90% sure it's Graves, TSH level around 004, thyroid swollen, 40 yo male with history of heart disease on one side of the family.
Yes!!! Beta blockers are a tremendous help. I took 50 mg Atenolol (generic) during the months of testing for a toxic nodule. It lowers BP and heart rate. Also, beta blockers block the thyroid hormones from hitting your other organs. It is fairly inexpensive too. $6.80/mo. without insurance. I had no side effects like dizziness. I just felt better overall. I seemed to sleep better when I took it before bed time.
However, as my nodule grew stronger, Atenolol did not stop my hands from shaking or help with sleep. My Dr. did not increase the dosage. :( Low dose Methimazole stopped the shakes.
I think there is a common misconception that once you start beta blockers, you are on them for life. Not so. I tapered off 1 month after RAI. When your T3 & T4 are within normal ranges, you will no longer need it.
