I totally agree. The psych who scripted this is an idiot. He obviously doesn't know how to dose with Cytomel. I think he is using it for more behavioral issues than knowing about the thyroid and how it really works.

I don't want to say to get off the Cytomel. I think it could benefit you and if the Cytomel does balance off the bipolar disorder, ( which is strongly connected to the thyroid) using the T3 Cytomel could get you off those other bipolar meds.

BUT - the psych needs to get "his head examined" He can't just put 25mcgs of Cytomel in you all at once and send you on your way. what an I D I O T !!!

I would bet if your taking the Cytomel in the AM you are spiking hyper symptoms for the first 4 hrs after taking it and then suddenly crashing through the afternoon into hypO thyroid.

That's very tough on the body's system. On top of bi polar meds suppressing the thyroid throughout the day, you must feel like a walking zombie by dinner time?!?!?!?

I think the time of testing you did while on the Cytomel alone is extremely important too. If you test while the Cytomel was high in your system - your labs would look like this - but that doesn't mean you would have tested the same way - IF you tested after the Cytomel wore off. I bet those labs would indicate hypo symptoms. and it's a blessing you did test when you did.

You need to split that dosage and monitor your Cytomel. It a short lived T3 med and needs to be administered every 4 hrs to maintain stability. In addistion and suggestion to this "psych" for you would be to ask for a small amount of Synthroid would be good. If your not on it know maybe see if you can ask for a low dose like .25mcgs to start.

You may also want to suggest decreasing the bi polar meds too. not get off them -  but see if a lower dose (small) would benefit you with the Synthroid and Cytomel taking over to help you.

Damn!!!! - Where to these quacks get there education?

Cytomel is not the usual response to hypothyroidism. T4-only meds like Synthroid, Levoxly or genereic levothyroxine are much more ordinary.

Your TSH is very low, indicating hyperthyroidism, or overmedication.  However, your FT4 is very low, indicating hypothyroidism.  It's hard to say what's going on not knowing whart your labs were before starting Cytomel.  I'd really like to see FT3.

25 mcg of Cytomel taken just once a day is a bit odd.  Usually, T3 meds are split into more than one dose throughout the day to avoid the peaks and valleys of the fast-acting T3.  

I have heard that almost all bi-polar drugs interact with thyroid meds.  A psychiatrist may not be the best doctor to treat your "thyroid condition".  Maybe you should find a good endo.  I seriously question the Cytomel prescription without an FT3 test.  Find  someone qualified to treat thyroid.  With your FT4 being so low, I'd think about a T4 med (Synthroid, etc.) way before I'd prescribe Cytomel (but, then again, I'm a patient, not a doctor).

I don't know what my results were before the cytomel, but I have bipolar and my Dr. wanted to address my thyroid problem thinking that was why I was still depressed and lack of energy.  I am on Symbtax 6-25mg for bipolar, ritalin 60mg & concerta 72mg.  All I know is my family Dr. said my thyroid was a little off, so my psychiatrist had the results faxed to him and he put me on cytomel right away.  Now my family Dr. called today with my new lab results and said that my Psychiatrist is going to have to deal with it since he put me on the cytomel to begin with, and he hasn't called me to tell me what to do.  All I know is I'm feeling much better, but obviously something is not right with these results.

Are yoiu on any other thyroid meds as well, or just Cytomel?  If so, what is your dosage?  If not, why are you on T3-only med (Cytomel)?  What were your labs a week ago before going on the Cytomel, and were you on any other meds then?
