My wife has thyroid hormone levels issue and most recently performed thyroid function profile test and got issue with tsh (thyroid stimulating hormone) which gives observed value 20.523 uiu/ml, reference range 0.35 - 5.5 uiu/ml. She used to take thyroxine sodium tablets ip (thyrox-75) earlier and she stopped taking this medicine since last 2 month and this may be the main reason for getting high level of tsh. Kindly advice for better medicine to get rid of from thyroid harmonic issues.
