DO NOT suddenly cut back on your doseage. Your thyroid is now dependent on your current doseage and you will have to taper down slowly. Assuming you are taking 6 tabs a day (25mcg's), cut back to 5 tabs for 4 days, then 4 tabs 4 days, 3 tabs, 2 tabs, and 1. Give your own thyroid a chance to recover and come back into play if you are considering stopping. Please take it from someone who was bedridden because she just stopped!!
