NP Thyroid
By NP Thyroid
Your thyroid function may be as unique as your personality. Those suffering from hypothyroidism or Hashimoto’s disease (Hashimoto’s thyroiditis) may fall on a wide spectrum of thyroid dysfunction. Because thyroid hormone replacement therapies are not one-size-fits-all approaches, NP Thyroid® offers flexible, natural* thyroid replacement therapy dosing options.

Variety of Tablet Strengths Available for Once-Daily Dosing

NP Thyroid® offers the following dosing options: 15 mg, 30 mg, 60 mg, 90 mg and 120 mg. These tablets are easy-to-swallow, gluten-free and dye-free. NP Thyroid® provides a natural* desiccated porcine thyroid extract that helps balance TSH, Free T4 and Free T3 levels.

Benefits of Flex Dosing

With the availability of different strength tablets, healthcare providers are able to tailor dosing more accurately to your individual needs. If your thyroid replacement therapy dose is off by a little, it can change your TSH level and possibly cause symptoms of thyroid dysfunction.1 Dosing that achieves a more narrow therapeutic range can bring thyroid levels into balance. By aligning thyroid dosing with a patient’s individual needs, thyroid levels can be normalized.

The Natural* Thyroid Hormone Replacement Therapy

NP Thyroid® is an alternate therapy to levothyroxine sodium and other natural* desiccated thyroid products. Thyroid replacement therapies with levothyroxine use a synthetic or man-made version of the principal thyroid hormone, thyroxine (T4).2 NP Thyroid® provides a natural* desiccated porcine thyroid extract that is dependable, consistent and readily available to all U.S. pharmacies. NP Thyroid® is made with the highest quality standards under Current Good Manufacturing Practice (cGMP) regulations.

Important Risk Information

Drugs with thyroid hormone activity, alone or together with other therapeutic agents, have been used for the treatment of obesity. In euthyroid patients, doses within the range of daily hormonal requirements are ineffective for weight reduction. Larger doses may produce serious or even life-threatening manifestations of toxicity, particularly when given in association with sympathomimetic amines such as those used for their anorectic effects.
  • NP Thyroid® is contraindicated in patients with uncorrected adrenal insufficiency, untreated thyrotoxicosis, and hypersensitivity to any component of the product.
  • In the elderly and in patients with cardiovascular disease, NP Thyroid® should be used with greater caution than younger patients or those without cardiovascular disease.
  • Use of NP Thyroid® in patients with diabetes mellitus or adrenal cortical insufficiency may worsen the intensity of their symptoms.
  • The therapy of myxedema coma requires simultaneous administration of glucocorticoids.
  • Concomitant use of NP Thyroid® with oral anticoagulants alters the sensitivity of oral anticoagulants. Prothrombin time should be closely monitored in thyroid-treated patients on oral anticoagulants.
  • In infants, excessive doses of NP Thyroid® may produce craniosynostosis.
  • Partial loss of hair may be experienced by children in the first few months of therapy but is usually transient.
  • Adverse reactions associated with NP Thyroid® therapy are primarily those of hyperthyroidism due to therapeutic overdosage.
  • Many drugs and some laboratory tests may alter the therapeutic response to NP Thyroid®. In addition, thyroid hormones and thyroid status have varied effects on the pharmacokinetics and actions of other drugs. Administer at least 4 hours before or after drugs that are known to interfere with absorption. Evaluate the need for dose adjustments when regularly administering within one hour of certain foods that may affect absorption.
  • NP Thyroid® should not be discontinued during pregnancy, and hypothyroidism diagnosed during pregnancy should be promptly treated.


NP Thyroid® (thyroid tablets, USP) is a prescription medicine that is used to treat a condition called hypothyroidism from any cause, except for cases of temporary hypothyroidism, which is usually associated with an inflammation of the thyroid (thyroiditis). It is meant to replace or supplement a hormone that is usually made by your thyroid gland.

NP Thyroid® is also used in the treatment and prevention of normal functioning thyroid goiters, such as thyroid nodules, Hashimoto’s thyroiditis, multinodular goiter, and in the management of thyroid cancer.
