(also known as Thyrax, Euthyrox, Levaxin, Eltroxin, Levothyroxine, L-thyroxine, Synthetic T4, Levothroid, Levoxyl)
Levothyroxine is a synthetic form of thyroxine (thyroid hormone). As the hormone is chemically in the L-form (instead of D, see chirality), it is metabolised much slower than physiological thyroid hormone, which has a shorter half-life. more at Wikipedia

I do not find it to be working. I found an Endocrinologist and have been retested and will get my results this Wednesday.
