What it is
NP Thyroid is a desiccated thyroid tablet. It contains thyroid hormones derived from porcine (pig) thyroid glands, including levothyroxine (T4) and liothyronine (T3). A licensed provider may prescribe it for patients with hypothyroidism, a condition in which the thyroid does not make enough hormone.
This medication is not FDA approved. The FDA has not evaluated it for safety, effectiveness or quality.
How it works
Thyroid hormones help regulate how the body uses energy, including heart rate, body temperature and metabolism. When the thyroid does not make enough, replacement hormone can help bring levels back into a normal range.
Desiccated thyroid supplies both T4 and T3. Your provider determines the dose and adjusts it based on your lab results and how you respond.
What to expect
Treatment begins only after a provider reviews your symptoms, health history and thyroid lab results. Doses are usually adjusted gradually, and follow-up lab work is part of treatment for as long as you remain on therapy.
Your provider sets your dose and schedule. Individual responses vary, and results are not guaranteed.
Who it is for
Whether a thyroid hormone is appropriate for you is a decision made by a licensed provider based on your symptoms, examination, laboratory results and health history. It is not appropriate for everyone, and it requires ongoing monitoring.

Serious effects can include heart rhythm problems, worsening of heart conditions, and reduced bone density with long-term over-treatment. Allergic reactions are possible. Contact your provider promptly about chest pain, a rapid heartbeat or shortness of breath.
