I am almost exactly 4 months post op and am probably just a few weeks away from getting my synthroid dose just right. I will more than likely wind up taking 88 mg. This is what I was started on after surgery but it initially made me too hyper. It's been 4 months of gradually raising, lowering and raising again my dosage. I have become very, very aware of when I'm crossing over from being hyper to hypo. It was difficult in the beginning. I was wiped from the surgery (had complications). Add to that the way you feel when your levels are not correct and I just felt like I couldn't deal with anything. That feeling has mostly gone away. I'd say I'm about 90% right now. The worst part of it right now is my impatience. I've had blood work about every 4 weeks or so which has been good because the tests have caught "trends" so my meds could be changed before I felt really bad. After reading some other posts here I consider myself one of the lucky ones. Make sure you keep communicating with your doctor, write down how you feel and pay attention to what your body is telling you. You'll be fine.
Well get ready to learn patience. It took up to a year to get me on the correct dosage. I had the RAI before surgery (TT), I did not end up having cancer, so I was put on medication right after surgery.
It does take a bit to get you on the correct dosage, maybe not a year for you, but just be patient, get your blood work done (usually 4-8 weeks after every dosage change), keep your doctor informed of ANY new symptom you are having.
I stayed on the same dosage for 10yrs. (200mcg) then for some reason went hyper again and went through another year of dosage adjustment. Now on the same dosage for the past 3yrs.
Thank you for your reply. How long does it usually take to get a dosage figured out? I am taking 100mcg a day right now but the doctor said we will probably need to increase it. Once a dosage is stabilized, does it usually stay the some or will I need to change it often?
I think it is usual to start you on thyroid hormone straight away. As you no longer have a thyroid you are not producing hormones. Waiting several weeks before starting meds would push you hypo, which would be very unpleasant and not good for health. You will have to adjust meds anyway, but that takes time. Depending on your dose you may get hypo symptoms anyway...
Can't comment on the RI as that's outside my experience, but guess they do that to catch any remaining thyroid cells. Others will chime in here.
