Hi and welcome to XXXXXXX

It should be taken on empty stomach, the whole tablet, 1 hour before breakfast (or 1 hour before other meal if cant be taken in the morning) with full glass of water. Dont crash it

Synthroid dose should be reduced gradually and with caution. It shouldnt be switched from 50 to 25 in one or few days. In this case, TSH and thyroid hormonal levels variations may cause symptms you ve experienced. SO you should for example take 5 days in week 50mg and then 2 days 25. And then 4 days 50, 3 days 25, and so on.
But all this should be followed by thyroid hormones levels checks.

Wish you good health. Regards
