Levothyroxine for thyroid from Lupin Pharmaceutical (Rite Aid) [View all]
Anyone taking generic levothyroxine manufactured by Lupin Pharmaceutical for low thyroid function might want to have their TSH, T3, T4 levels tested, especially if you're feeling a bit "off."
(Lupin won the right to manufacture and sell levothyroxine in late 2019—Rite Aid began to offer it as their generic thyroid medication)
A few months ago I had my TSH checked and it came back mysteriously low. After a little digging I discovered the Rite Aid switch to the Lupin drug, and that it might be working on me differently (not all generic levothyroxines are the same, I guess).
I asked to be changed to the brand name Synthroid and had my levels tested again after a few weeks. They're back where they should be. I feel loads better too.
Synthroid may not be for everyone. It's about 2 1/2 times the cost of the generic. And there may be another generic out there that works just as well as the brand.
This isn't a plug for Synthroid nor a knock on Lupin. I just thought I'd share what can happen with different drug manufacturers.
