Welcome to HCM. I had gone through your question and understand your concerns.
1. Graves disease (hyperthyroidism
) after radio iodine
treatment or surgery will become hypothyroid. So treatment is replacement with Eltroxin
in both cases.
2. Diotroxin is a combination of T3 and T4 (thyroid hormones) and Eltroxin is T4. T3 is active form, so if you need faster action we can use diotroxin,, while eltroxin will be useful in most of the usual situation as in our body T4 will be converted to T3.
Hope I have answered your question. If you have any further questions I will be happy to help.
