What is Natural Desiccated Thyroid?
Natural desiccated thyroid (NDT) is a natural medication used to support patients with hypothyroidism. Unlike synthetic thyroid hormone treatments, which only contain T4 (thyroxine), NDT provides both T3 (triiodothyronine) and T4.

USE:
RenThyroid™ (Thyroid Tablets, USP) is a prescription oral medication used to replace or supplement thyroid hormones in patients with hypothyroidism from any cause, except transient hypothyroidism during the recovery phase of subacute thyroiditis.
Note: RenThyroid has not been reviewed by the FDA for safety or efficacy.
IMPORTANT SAFETY INFORMATION
Thyroid hormone drugs, including RenThyroid, should not be used either alone or in combination with other drugs for the treatment of obesity. In patients with normal thyroid function, normal doses for daily hormone replacement are not effective. Larger doses may cause serious or even life-threatening events, especially when used in combination with certain other drugs used to reduce appetite.
- RenThyroid should not be used for male or female infertility unless this condition occurs with low thyroid levels.
- Taking too much RenThyroid may affect your cardiovascular system, especially if you are elderly or have heart problems. Tell your doctor immediately if you have any signs of chest pain, increased pulse, palpitations, excessive sweating, or any other unusual event.
- Tell your doctor about any other medical conditions you may have, especially heart disease, diabetes, blood clotting problems, and adrenal or pituitary gland problems. The dose of other drugs you may be taking for these conditions may have to be changed while you are taking RenThyroid. If you have diabetes, monitor your blood sugar levels and/or the glucose in your urine, and immediately tell your doctor if there are any changes.
- Tell your doctor about all of the medicines you take, including prescription and over-the-counter medicines, vitamins and supplements. Especially tell your doctor if you take anticoagulants, diabetes drugs, oral contraceptives, or biotin.
- In infants, excessive doses of RenThyroid may cause a condition called craniosynostosis (premature closure of the skull bones).
- In children, partial hair loss may occur during the first few months of taking RenThyroid.
