I recently found out that there were maize and acacias fillers in the new version of eltroxin. I changes to tirosint which has almost no fillers/exipients. Also lowered the dose and switched to taking it at night. My Irritable Bowel Syndrome (IBS) symptoms miraculously cleared up but the ringing in my ears is much worse. MRI shows no reason for the problem. In the past this has been a sign of allergy or toxicity (aspirin, etc). Anyone else have ringing in the ears with levo?
