I will look into generic. I am paying 4times this now. I will try to post my latest blood work thanks
This is related to the other question you asked about generic vs brand cytomel. It's always best to keep related questions together.
While you may not feel that 5 mcg cytomel is not making a difference, most likely, it is, even though it may be subtle. I was on 5 mcg for quite a while before my endo finally agreed to increase to 7.5 mcg/day and I'd even forget to take it on occasion. If you forget often enough, you'll know the difference.
Cytomel is fast acting and doesn't stay in your system for very long - it peaks within a few hours. Its half life is only about 1 to 1.5 days. I never really noticed a huge difference when I take it either, but I do notice a difference when I miss more than one dose - of course, I'm now on 10 mcg/day and take it in 2 doses.
If you stop taking it, it would be out of your system within a few days. It could take a bit for your own conversion to ramp up, so you might feel some symptoms before that happens.
Before I'd recommend stopping the cytomel, I'd want to know what your actual thyroid hormone (FT3 and FT4) levels are. I'd probably suggest a switch to generic liothyronine before completely stopping the T3. I buy a 90 day supply of generic liothyronine (5 mcg X 2 daily) for $21 ($7/mo), with insurance.
