ERFA® thyroid is a T4/T3 combination medication which is made from desiccated (dried) thyroid extract and is used to treat conditions where the thyroid gland does not make enough thyroid hormone. This includes Hypothyroidism and Hashimoto’s Thyroiditis. It can also be used in the treatment of Myxedema and to prevent against enlarged thyroid glands (goiters).
Unlike synthetic thyroid medications, ERFA thyroid is a natural extract that contains both T3 and T4; synthetic versions typically only contain T4.
