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.
Thyroid levels on Synthroid vs. Levoxyl?

I was told that the Synthroid and Levoxyl are the same exact medications, different manufacturers so there should be no difference in taking Synthroid over Levoxyl at same dosage. Doesn't seem to be the case.
You have proof its not helping as much if your TSH is going up like that. The TSH is thyroid stimulating hormone, not thyroid hormone. Its the hormone that is from the brain that triggers the thryoid to produce hormone. The higher the TSH is the lower the thyroid hormone. Its the brain trying to make the thyroid work. So the low numbers are the best. Different manufacturers must use the same active ingredient, but they can have different inactive ingredients which can change the absorption of the meds. Are you taking it in the morning half an hr before you eat anything else, with only water?
