McCall McPherson argues levothyroxine (T4-only) therapy is ineffective for most patients and recommends desiccated thyroid products like Armour or T3-based medications instead. None of his Modern Thyroid Clinic patients stay on T4-only therapy.
Chapters
Pretty much all medications for thyroid. Pretty much anything that isn't levothyroxine based is better than levos. So those are desiccated thyroid medications like Armour, Adtheza, NP. They are active thyroid hormone T3 based medications like Cytomel, Leothyronine or a combination of Cytomel leothyronine and levothyroxine synthroid 2% but other of all the patients I have at modern thyroid clinic, I do not have a single one that is on T4 based medications. Levothyroxine based medications alone. Can they work for some people? Sure. If you're one of those people, just go to Vegas and buy a lottery ticket because you are freaking lucky. And a lot of people not so much.
