Wow! I hope with your medication that you start to feel better soon!
Generics can work, but with Synthroid you can be sure you are getting the exact dosage of T4 every time. Since your doc prescribed Synthroid, I would go back to the pharmacy and see if you could change it back. If it is an insurance thing, well, I hope they cover brand names for you. Maybe it is a case where the doc prescribed the brand name drug and the insurance only covers the generic drug.
If you do not get symptom relief with the T4 meds, I suggest doing more research on these pages and at
www.realthyroidhelp.com. There are lots of people here on the PCOS board and there who know their stuff when it comes to the thyroid. That's where I found my help!
