Unfortunately I am not on any of those medications. Actually, I am on medications that makes my uptake readings LOWER. I am on an antihistimine which is also a central nervous system depressant in attempts to lower my heart rate. This was recognized on my RAI scan which says that my uptake is actually higher then 58.5 due to the antihistamine! It’s all crazy. If you were me, who would you contact in hopes of answers?
