Since Lyme, I've been put on levoxyl (same as synthroid) and cytomel (a T3 med.) There is some evidence that autoimmune thyroid disease is actually an infectious process, and will improve with antibiotics. I'm hoping, but it hasn't happened yet.

The good news is that thyroid supplementation has a long history of safety as long as the supplementation is at the appropriate level.

I'm having regular checks on my thyroid levels, and believe me, if I need less, I'll take less! In the meantime, it has taken away that feeling that no matter how long I sleep, it is never enough, my skin and hair are not dry anymore, and I no longer get swelling in my throat and tongue.

I don't know if your thyroid function returns after Lyme. Everything I read says you are on synthroid for life.

I was put on synthroid as well, the good news in my case, is that I have been off the synthroid for about a year and continue to test normal.

So for me, I only had to take it for about a year

Best wishes to you and your wife!

I've been on Synthroid 100 mcg since being a teen...until Lyme.

I do go to an endocrinologist and have for years for my yearly thyroid tests, but because of Lyme, my test results changed, and I've changed dosages twice since then...once to 88 mcg, then to 75 mcg, which is what I take now.

Weird!

Good luck.
