I'm 26 years old and have been on a very low dose of Levothyroxine (.25mcg) for the past decade. Blood tests have confirmed that this dose is keeping my levels at a normal range. I recently got a new doctor through my mental health clinic and she said I should take more to boost my mood and give me more energy, so she gave me a new prescription for .75 mcg. My question is, is it safe to take more than I need? I know she is a doctor, but I'm quite worried about the health risks of introducing more hormones into my system than is necessary.
There is a normal range for your thyroid levels. As long as you don't go out of that range you should be fine. You might want to insist that you get a new blood test after 60 days so you're sure you're within the normal range still. But usually bumping up such a small amount won't hurt and may actually give you the benefits she's looking for.
