I've been taking levoxyl for 21/2 months. Initially my TSH was 4.1 but I was pregnant so my Dr said she wanted to put me on meds to bring the level down. It worked to bring the level down to 1.2 within 3 weeks. Unfortunately I miscarried, but the Dr. said to stay on it. Since then I've experienced hair loss, anxiety, insomnia and extreme vaginal dryness. I thought it was a hormonal imbalance until I accidently left my meds at home on a 3 day vacation. All of my symptoms went away by the 3rd. day. So I'm a little suspicious! My doctor dais to go off it and they'll re check my TSH in 3 weeks. Lets pray it stays down because I don't want to ever be on that drug again!!
