How long to feel change in Synthroid dosage??

I have another question! Hopefully someone who has been taking Synthroid for a few years can answer this.
I have been taking Synthroid for over a year. At first my dosage was .5, then it was reduced to .25, and now for about 2 1/2 weeks I have been taking the .5 dosage of Synthroid. It was increased because my TSH Levels were low and I have been gaining weight, feeling tired, cold, etc. So hopefully this change will make me fell and Look more like my normal self again!

But, I am not really feeling the changes yet and it has been 2 1/2 weeks. How long does it take for me to Feel and See changes??
I Do exercise and eat right. What else can I do, I am so sick of waiting around for so long to see changes!

Thank you.

I believe it takes six weeks.
My endo makes me get a blood test after seven weeks on the med and see him in eight.

Re: How long to feel change in Synthroid dosage??

kallai- Hang in there. It takes time to get your thyroid regulated. It takes about 7 weeks for the new dose to saturate the cells. I have read thet the symptoms sometimes will last a while after you are leveled. You may want to consider were in the range you fall some people do better in the middle and others on the ends. When you get you blood test done again in about 5 weeks that should give you an idea.
