Why are generic thyroid drugs a no-no? I just found out yesterday my thyroid levels are low and was prescribed Synthroid 50 mcg. The dr allowed a generic subsitition and I received levothyroxine. Last night after doing more reseach, I see that generic drugs are supposedly a no-no for hypothyroid. Why? If this is a drug I might have to be on the rest of my life, I'd certainly rather pay generic cost for it...
This is b/c the generics have at least 8 different producers -- the absorption and consistency between these sources may differ, that is why with a medication that has such a narrow therapeutic window (ie, TSH 0.5-2.0) we prefer to stick with a brand to ensure that patients receive a consistent product.
Hi, your so right about that doctors seem to focus more on prescribing synthroid, I had myxedema coma 3 years ago and never agin have been able to get my thyroid under control, the endos kept giving me synthroid, a lot of different doses form 112mcg to 150mcg,and the last one was 125mcg which would all get me hyperthyroid every single time,, until my new doc gave me a generic and i am on 125mcg of levothyroxine and its working great for now and I have not gone hyper like i do with 125mcg within a few weeks on it, so generics work best for some of us and are cheaper too! but docs just focus on synthroid, I am glad i went to see a regular doc and he gave me this because I havent been feeling sick as i normally do on synthroid, of course i will stick with the same brand but i will definitely not go back to synthroid
