Mother in law thinks she has or will get liver problem from generic synthroid. She has taken it for a few months & now says she has dark stool & blames the synthroid. However she just went to hospital for chest pain she thought was heart but indigestion from the chili ch. I have to agree she wants to find something wrong. But aleese hot dog & fries. She is 81. Her sons say she is hypocondriac I can see is possible difference in delivery of the thyroid med in the generic which is debatable but nothing about liver problems. She said a pharmacist told her there was problem with generic synthroid meds & liver.
