My wife lately has been experiencing side effects of Levothyroxine, such as extreme tiredness or general weakness and unstable movement/walking, She has been taking levothyroxine .05mg (50mcg) tab for around ten years, but it has been several days that she started to lose pep and appetite. I tried to make an appointment to see the doctor who prescibed this medicine for her, but she seems unavailable or would not respond to my calls or text messages. Should I stop my wife from taking the medicine, withoout consulting her doctor? Thanks you.
