Is it safe for an 86 yr old to stop levothyroxine 88 mcg,. It was prescribed after one blood test showing a slightly elevated tsh. since taking it her tsh levels have been normal but she has lost a lot of hair and nails are not growing nearly as before. She has been taking it for 1 yr. She is not seeing an endocrinologist and her pcp said she could just stop, even tho she did not recommend it. In general will it cause harm to stop suddenly with this low does or is it important that she does it gradually?. Please feel free to elaborate and thank you.
