NP Thyroid is a natural desiccated thyroid extract derived from porcine thyroid glands, containing both levothyroxine (T4) and liothyronine (T3) in their naturally occurring ratio. It is used as replacement therapy for hypothyroidism in patients whose thyroid gland does not produce enough hormone. Some patients and prescribers prefer desiccated thyroid over synthetic levothyroxine alone because it provides both T3 and T4, though clinical evidence of superiority is limited. As with other thyroid replacement products, dosing is individualized and guided by TSH and clinical symptoms, with caution in elderly patients and those with cardiovascular disease.

Levothyroxine is a prescription thyroid hormone used to treat hypothyroidism, a condition where the thyroid gland does not produce enough hormone. It works by replacing or supplementing thyroxine (T4), helping regulate metabolism, energy levels, and overall body functions. Synthroid is typically taken once daily, usually on an empty stomach in the morning.
Liothyronine (Cytomel) is a synthetic form of triiodothyronine (T3) thyroid hormone used to treat hypothyroidism.
Methimazole is an oral antithyroid tablet used to treat hyperthyroidism, including Graves' disease and toxic multinodular goiter. It works by blocking the thyroid gland from making new thyroid hormone, helping to bring hormone levels back to normal.
Propranolol is a prescription beta-blocker commonly used to treat high blood pressure, chest pain, irregular heart rhythms, and to prevent migraines. It works by blocking the effects of adrenaline on the heart and blood vessels, which slows the heart rate and lowers blood pressure, improving circulation and lowering strain on the heart.
Propylthiouracil (PTU) is an oral antithyroid tablet used to treat hyperthyroidism, including Graves' disease and toxic multinodular goiter. It lowers thyroid hormone levels by blocking hormone production in the thyroid and reducing the conversion of T4 to the more active T3.
