I am currently taking 150 mcg Thyroxine (T4) under supervision of an Endocrinologist for the past 18 years. I am getting Cytomel T3 tomorrow. So in what ratio should I take T3 and T4 ? 50 mcg : 100 mcg ? or should I start with 25 mcg T3. Endocrinologists in India have no idea or experience giving combination of t3 and t4. So what side effects if any that I should be on the watchout for ? Thanks in advance.
