Which has more side effects?

As in causing more of an increase in heart pounding, anxiety etc?

Synthroid or Cytomel?

I know it depends on the dose. But let's just say they were both an equal dose of T3.

Synthroid is T4. The body has to convert it to T3 (consider it a prohormone in that regard), so you can't compare them and get an "equal dose of T3" between the two.

Understood. Then why does my doc have me on T4 and T3? Why not just keep me on T3? Makes no sense to me. On my blood work, my T4 and T3 came out 20 points OVER the limit. So he downed my Synthroid from 200mcgs to 150mcg. But left my Cytomel at 25mcgs. I have to get blood work done next week to see if my T4 and T3 are within the normal range.

He said by dropping the T4 not only will blood work show lower levels of T4 (remember, its' 20 points OVER). But by lowering the T4...T3 should lower also. (also at 20 points over).

200mcg of Synthroid is at the top end of what pt's get prescribed. It is extremely rare that you'd find anyone prescribed over 200mcg. It makes sense to start by bringing that down to get your levels in range. It's not an exact science, so consistent bloodwork to monitor levels is needed in order to make adjustments.
