About Hypothyroidism

RenThyroid is the medication I wish I had as a patient—now, it’s my choice for my patients.

The Issue Isn’t
Just Your Numbers

Millions of patients are on medications like Levothyroxine (synthetic T4), which often bring their lab results into the normal range.

However up to 10-15% of people on T4 monotherapy still experience symptoms like fatigue, weight gain, and low energy.

If you’re still dealing with symptoms on T4 monotherapy, it might be time to talk to your doctor about RenThyroid.

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.
This is not a complete list of risks. For more information, please talk to your doctor and read the full Prescribing Information.
