I am trying to find out if raising Cytomel will lower T4 levels in a patient that has had a thyroidectomy? I know it can lower it for someone who has a thyroid, but not sure about someone post TT. Also, if it does lower T4, if you drop the Cytomel dose back down, how long until the t4 will fully recover?
Hello – In general, patients who are on T3/T4 combination therapy will have higher levels of T3 and lower levels of T4 than patients who do not have thyroid issues.
However, every patient will respond differently to a dose change – so any potential changes should be discussed in advance with your doctor, with follow up labs done a few weeks later to ensure the new dose is correct.
