Synthroid (thyroxine) or Armour Thyroid for  hypothyriodism?

Levothyroxine.: Levothyroxine, generic form of synthroid, has many advantages over armour thyroid. The armour product has significant batch to batch variation and has T3 (liothyronine) in it. Since the T3 (liothyronine) portion of armour has a very quick onset and short duration, it can wreak havoc with the ability to effectively treat hypothyroidism. Until there is a long-acting form of T3 (liothyronine) available, stick to levothyroxine. ...Read more

4-21-14 Thyroidectomy r/t thyroiditis, goiter.  On Synthroid (thyroxine) 137 mcg- hypo s/s returning have felt great for months.  Would adding Cytomel help?

Not specific: The signs & symptoms of hypothyroidism are not specific for hypothyroidism (not a single one). Recheck your thyroid labs. If they're normal, your symptoms are due to something else. Having said that, I'm happy to do a trial of Cytomel with the Synthroid (thyroxine) in patients who want to try as long as I don't make them hyperthyroid. Some people report feeling better with comparable labs taking a little T3. ...Read more
