How does your doctor determine what dosage is needed for this or other thyroid medications?
21 Aug 2009
First, was it prescribed by your endocrinologist or your surgeon? There are standard starting doses. Your labs should be run a minimum of every six weeks initially and you should be seen by your prescribing doc to review your labs and see how you are feeling. Then they will be adjusting up or down according. It can take up to a year to get it right or longer if you have had your thyroid removed. And it can also take med changes. You mentioned Synthroid specifically. This is only one thyroid supplement/replacement medication - and it's synthetic. There are others.
Hope this helped some. The most important thing is to be honest with your docs and take your labs the right way, some are fasting - some aren't.

It's the same on any FDA approved medications. There have been all different kinds of clinical trial studies with large numbers of people. They base the dose on what worked best on patients with symptoms similar to yours. Other than that this is why they call it "PRACTICING MEDICINE" ... they don't know anything for sure. If they did we could look our condition up on a chart and see exactly what to take, for how long, everything. It's trial and error if they don't luck out and get it right the first call.
