Mayne or Sun brand liothyronine

[Jasonk35000]

I am wondering if anyone has experience with either of these generic brands of cytomel? I realize everyone responds differently to different brands. I've always responded best to cynomel from Mexico, but can't really afford to pay out of pocket at the moment. So these are my options through my insurance and I'm trying to decide which brand to go with...

I've tried Sun, Sigma, and King Pharm T3 and I haven't been able to tell the difference. Usually just go with whatever generic is available. Pfizer's name brand Cytomel is too expensive for me and not covered by insurance. If you're in the US I use the goodRx coupons instead of insurance to get a bigger discount.

I believe that Greenstone is the exact same product as Pfizer Cytomel. (Viatris was formed from the Upjohn part of Pfizer and Mylan.)

However, I do find it difficult to keep up with availability of USA products.

Helvella I don't know if your aware that Mayne Pharma T3 is now Golden State. Originally it was Paddock. I wonder why it keeps on changing? Maybe you would know?

[helvella Administrator Thyroid UK in reply to jgelliss]

No - hadn't noticed that change!

From 28th February 2023:

Dr Reddy’s to buy US generic products portfolio of Mayne Pharma

(And also at one point called Perrigo.)

PS - To all - I am always wanting additions/corrections.deletions for my thyroid hormone documents.

[jgelliss in reply to helvella]

Yes it was Perrigo too. I was up for my script renewal and was told that Mayne Pharma is no longer available. I called Mayne Pharma and was told by a very nice person that indeed it was now Garden State by Dr Reddys. That everything will stay the same supposedly. Hopefully. Thank you Helvella for being on top of your game. If you have any further information please share it with us. Thank you so much in advance.

[jgelliss in reply to jgelliss]

Just as an add on please. Does anyone know if there is out there a 2.5mcg T3? It would be so very helpful and welcome.

[jrbarnes in reply to helvella]

You're correct! I keep calling it King pharma but it does say Greenstone on my bottle but on the pills they still print KPI. I feel lucky when they don't have enough of the Sun pharma to fill so they give me the greenstone ones, which I like much better.

[helvella Administrator Thyroid UK in reply to jrbarnes]

Aside from them having the same manufacturer (Peptido), the same tablet markings seems very much to confirm they are the same.

Imagine making two different tablets which are identical in looks! How could anyone in the factory be sure which they were? Or if issues arise in future.

[jrbarnes in reply to helvella]

Pfizer's name brand Cytomel is also marked with KPI and Greenstone is a subsidiary of Pfizer and the Greenstone tablets are also marked KPI. Not sure if I'm getting a "no name" or the actual name brand tablet because they're marked the same! The Greenstone tablets are half the size of the Sun pharma and Sigma.

This thread is entirely concerning USA liothyronine products.

Greenstone is, as said earlier, seemingly Pfizer Cytomel under different branding. Not available in the UK.
