> I'm sure someone here will know the answer to this. If you take thyroid blood level tests 6 hours after taking your morning cytomel (37.5 in my case), what difference would you expect on the levels compared to having the blood levels checked in the morning after fasting and no cytomel that morning? I have been taking the T3 as an add-on to Wellbutrin for 7 years. I'm confused as to how you know when there is really a problem with too much. Thank you.
The answer isn't hard and fast. It's generally the rule that a T3 (total) sampling is taken greater than 24 hours after the last dose of Cytomel. If nothing else, it should be done that way if your prior bloodwork was done that way. Whether you might have a problem with excess T3 would be more than having high blood levels, IMHO. You'd have some symptoms of hyperthyroidism. See: http://www.endocrineweb.com/hyper1.html
If you've been taking it for 7 years, it would be surprising to find that you're only now hyperthyroid.
