Hi Brenda:
Synthroid dosages are usually based on the person’s thyroid function levels. There isn’t a standard or average dose that I am aware of. I have not been on a different dosage every six weeks since having the first RAI treatment 2 years ago. It can be very frustrating. I often wish that someone would come up with an implantable thyroid pump (like the insulin pumps some diabetics use) that would be able to sense changes in our metabolic demands and dose us accordingly. As for T3, I have heard stories about people having miraculous results with this, and I have heard an equal number of stories about people having horrific side effects and complications arise with it’s use. My own endo won’t even consider TRYING this on me; it’s not the standard of practice, at least not in my area anyway
Denise – you pose an interesting question about RAI. Both times I received it the dose was calculated based on the results of an uptake scan and the size of my goiter, so hopefully, I didn’t get more than what was needed to do the job. I’m not sure if there is such a things as too much RAI, or if so, how this could be determined, This may be something we could ask about at the conference this week.
Re: normal pulse rates. I do not pay much attention to my own pulse rate on a day-to-day basis, however if I can feel each heartbeat in my hands, feet or eyes, or hear it in my ears, I know I’m in trouble.
