Hi, I'm 20 years old and have been on the same dose (25mcg) of levothyroxine since I was diagnosed with an under active thyroid a few years ago. Over the past year and a half a lot has happened in my life and the tablets went to the back of my mind and I went months upon months without taking a single tablet. And my question is, should I be worried the fact that i haven't taken a tablet for about 7 months? Thanks.
