Dear Sir/mad I have gone through your question. I can understand your concern. Can you tell me if you feel : • Cold extremities • Cold sweats • Night sweats Or Sweat a lot in arm and your body? (and this is hyperthyroid problems) Did you check thyroid function, Until you begining the therapy ? Initial dose: 25 to 50 mcg/day, with gradual increments in dose at 6 to 8 week intervals, as needed -Initial dose: 12.5 to 50 mcg orally once a day; dosage can be increased in 12.5 to 25 mcg/day increments every 2 to 4 weeks (accompanied by clinical and laboratory assessment, until the TSH level is normalized) My advissed is to the thyroid function TSH ,FT3 FT4 and than to discutation about the dose . You must to know that : -The dose should be individualized on the basis of clinical response and biochemical tests. -This drug should be taken in the morning on an empty stomach with water, at least one-half hour before any food is eaten. -This drug should be taken at least 4 hours apart from drugs that are known to interfere with its absorption. -The peak therapeutic effect of this drug may not be attained for 4 to 6 weeks. So you change the dose every 20 days , in my opinion it must change every 10-14 days . So please chekc thyroid function and counsoult with your endocrinolog. To see if your thyroid is underactive or hyperactive? Hope I answered your questation and don’t hesitatetd to ask me please Kind regards Klodiana Poshi
