Was on Levoxyl for 12 yrs then due to recall of drug I had to go on Synthroid, same dosage .125mcg. Levels were .45 when I had to switch, then went up to .75, now 1.3 which Endo says is right in the middle of range. I'm gaining weight now. When I was on Levoxyl, I was told to stop taking the medication one day (only take 6 days a week) because my thyroid was high. I'm confused. Did that mean I was Hypo or Hyper thyroid? I can't seem to get enough answers from my Endo. I felt so much better on Levoxyl when reading was in lower range (more towards Hyper? i.e .45). Any help to understand this is appreciated. This is confusing.
