sir my wife was tested for thyroid function, because of weight gain, hair loss, fatigue and menopausal irregularities. tsh =9, t3 lower side of normal, t4 normal and anti tpo positive. the doctor said it is hypothyrodism and prescribed thyrox 50mg. my question is do my need to take medicine, can we stop after tsh level becomes normal, what are the side effects of thyrox 50
