<<Disclaimer: Verify this information before applying it to your situation.>> Hello, Everyone, I'm wondering if anyone who has both Celiac Disease and Hypothyroidism has experienced a difference between thyroid hormones Synthroid and Levoxyl. From the research I have done through the list archives, both are gluten-free. However, I have been on both, and something in the generic -- Levoxyl -- upset my system (I felt bloated, much more tired, and generally "out of sorts"), while I experienced nothing like that on Synthroid, which is the name brand. The inactive ingredients in each differ somewhat, so I suspect that that is where the problem originated. I know that both have lactose in them, so I don't think that was the problem, even though I am lactose-intolerant, because I feel much better on the Synthroid (which is what I am on once again). My diet has been gluten-free and stayed the same for over 2 years now, ever since my diagnosis. Has anyone on the list had a similar experience, feeling better on one formulation of thyroid hormone than on the other? Thanks in advance for your responses!
