Thank you so much for answering so quickly. I researched some on the fillers that you mentioned, and it makes perfect sense. I pick up my new prescription today, and I feel better about trying it, thanks to your post. I do not have any hypo symptoms, except the dry skin, though also an uncomfortable feeling when lying on my pillow at night, around my neck area, like its swollen. I will post update after I try the new dosage. Thank you again, you cannot imagine how much better I feel.
If you read the dosing instructions for levo, you will see that starting dose if you are over 50, have a history of a heart arrhythmia or have been hypo for more than a few months is 12.5-25 mcg, increasing as tolerated. Your body has to get used to having those hormones available again.
Have you tried taking the 25 mcg yet? It's unusual for a single dose of levo to affect you that quickly. Levo has to build in your system over several weeks before it changes your levels significantly. However, some people are sensitive or allergic to the fillers (inactive ingredients) in the tablets. An immediate reaction usually has more to do with that.
How do you feel? Do you have many hypo symptoms?
Did your doctor test anything else besides FT4?
