Take daily,on an empty stomach at least an hour before eating (majorly important)!Be sure to get blood work done yearly,asking for a full panel view this is to get your TSH numbers. I thiught PG was getting this done. Before I knew it my TSH was 21.1 and they ideallt want your to be in 2.5 range with a fluation up to 4 or down to 1 so you can see mine was high. Did it affect me yes it did. My ankles began to swell (first sign) then, my weight changed, my hair began to fall out and terribly dry skin. There were sevreral things going on in my life at the time. Large impact takes twelve wks or more to correct. don't let this happen to you get routine blood work done, yearly.
Take this as your blood work shows you need it, the problems of low thyroid can slip up on you and it takes the medication a long time to become effective. Never increase without proper blood work. NEVER decrease without same and never let a thyroid test done while you are in the hospital under stress be used as a basis for treatment level. This happened to me last year and it took all year for my family doctor to get my levels correct again.
