Re: anyone take meds to prevent goiter...
I was on Levoxyl to shrink my goiter that was caused by Hashis. It worked at first but then it didn't work. I gave it a year and my goiter was just too big. I couldn't swallow too well. Had to have my thyroid removed.
Medication does help some people with the enlargement though. It will not prevent your thyroid from eventually quitting, just prolong the process. I hope that the synthroid works for you.
