I was on 1 mcg generic levy thyroxine - manufacturer - Mylon. My doctor switched me to Levoxyl 1.12 mcg - manufacturer - Monarch-james. My TSH was 4.28 and the doctor said that he would like to see it in 3 range and bumped my dosage. Since this change, I have started to loose hair and feeling aches in hip and my bones are brittle. My fingers in both hand and leg hurt too. I am feeling bloated, started having diareah for last two days. I feel more energetic though but am not getting sleep quick. Is the change in manufacturer is a mistake my doctor made. or Levoxyl it self has lots of issues. I understand that they are both levythyroxine. Can some body expain what I need to do. I have been having panic attacks and severe anxiety too.
