I've recently had an issue with a generic liothyronine here in the US, which is manufactured by a subsidiary of Pfizer. It felt like I was taking nothing. Today, I transferred the prescription to a different location to get another generic by Sigmapharm. I notice Sigmapharm does not put Talc in their pills. Has anyone had experience with Talc affecting the efficacy of liothyronine pills or is it simply down to poor manufacturing?
I knew something was off when I took 10 mcg of the liothyronine and felt no therapeutic benefit. The next day I took 1 grain of NDT, which has 9.5 mcg of liothyronine and felt positive improvements within the hour.

Yes, it is distributed by Greenstone and embossed with KPI 115, for King pharmaceuticals. I reported it to the FDA as well as the pharmaceutical company.
There is these #s on the pill.52020.Unfortunately I cannot give you more info. because the 90 days supplies I get are thru a plastic bottle.Good luck to you
Many thanks for posting about your experiences with King Pharmaceuticals liothyronine. As Cynomel (Sanofi-Aventis, France) is currently unavailable in Israel, I ordered from a US pharmacy, what I was told was Pfizer brand-name Cytomel. When I asked the pharmacy why it came from King Pharmaceuticals, I was told that King Pharmaceuticals was purchased by Pfizer; therefore, they are the same company. I have used this pharmacy in the past, and consider them reliable.
By the way, the embossing on my pills is KPI 116, very similar to yours. So even assuming that I was sent Cytomel, and not a generic, there may be a problem with the King Pharmaceuticals version. I have not yet tried my tablets, as I still have a little of the Sanofi-Aventis Cynomel in stock.
Has anyone else had experience with King Pharmaceuticals Cytomel, or the generic version?
It is confusing when a large company purchases another. I was paying for a generic but had I requested the name brand Cytomel it would have come from the same place with the same embossing, only I would have payed more. KPI 116 is the 25 mcg and KPI 115 is the 5 mcg.
I have not read of any problems with Cytomel so I may be sensitive. Please let us know if you experience any bad side effects.
Unless I am mistaken, what jrbarnes seems to be telling me is that I paid (alot?) more money by requesting Pfizer brand-name Cytomel, now manufactured by King Pharmaceuticals, for the exact same product that I would have been sent had I requested the generic liothyronine, and for (alot?) less money.
The only reason I didn't request a generic in the first place was because at first, I had wanted to try a product that most closely resembled Cynomel (Sanofi-Aventis, France), which I have been split-dosing and taking for years, and to which I have adjusted reasonably well.
jrbarnes, if you end up ordering generic liothyronine from Sigmapharm, please let me know if you respond positively to this brand.

I so appreciate your response. I'm still using up my Cynomel (Sanofi-Aventis), will then try the Pfizer/King Pharmaceuticals Cytomel, and will order the Sigmapharm generic the next time I need to replenish my liothyronine supply.
I often suggest people try a new or different medicine while they still have some of their existing medicine available. The simple reason being that if it goes wrong at all, you have the option of reverting - at least for a while.
Thank you. Your point is very well taken, and I will try the new brand of liothyronine (Pfizer/King Pharmaceuticals brand name Cytomel). I may have to change the timing of my split-dosing, though, depending on how hard it is to split the pill into quarters. The 25 mcg Cytomel tablet that I just now received is only scored to be split into halves.
The only reason that I would hesitate at all is that healthwise, I'm trying very hard not to rock the boat.
