NP Thyroid (thyroid tablets) is indicated for the following purposes:

  • Treatment of Hypothyroidism: NP Thyroid is used as replacement or supplemental therapy in patients with hypothyroidism of any etiology, except transient hypothyroidism during the recovery phase of subacute thyroiditis. This includes cretinism, myxedema, and ordinary hypothyroidism in patients of any age, state, or pregnancy; primary hypothyroidism resulting from functional deficiency, primary atrophy, partial or total absence of the thyroid gland, or the effects of surgery, radiation, or drugs, with or without the presence of goiter; and secondary (pituitary), or tertiary (hypothalamic) hypothyroidism.
  • Treatment or Prevention of Goiter: NP Thyroid is used in the treatment or prevention of various types of euthyroid goiters, including thyroid nodules, subacute or chronic lymphocytic thyroiditis (Hashimotos), multinodular goiter, and in the management of thyroid cancer.
  • Other Thyroid Disorders: NP Thyroid is also used to treat other types of thyroid disorders such as certain types of goiters and thyroid cancer, and to test for thyroid function.

NP Thyroid is a natural preparation derived from porcine thyroid glands and is a natural product made from animal thyroid glands, usually a pig's. It contains T4 (levothyroxine) and T3 (triiodothyronine) in a 4:1 ratio.


  • Take NP Thyroid by mouth as directed by your healthcare provider.
  • Usually, NP Thyroid is taken once daily on an empty stomach, 30 minutes to 1 hour before breakfast.
  • The dosage is based on your medical condition, laboratory tests, and response to treatment. For children, the dosage is also based on age/weight.
  • Use NP Thyroid regularly to obtain the most benefit from it, and take it at the same time each day to help remember.
  • Certain medications, such as cholestyramine, colestipol, colesevelam, antacids, sucralfate, simethicone, iron, sodium polystyrene sulfonate, calcium carbonate, orlistat, can decrease the absorption of thyroid hormone. If taking any of these drugs, separate them from NP Thyroid by at least 4 hours.
  • Be attentive to symptoms of low thyroid hormone levels, such as tiredness, muscle aches, constipation, dry skin, weight gain, slow heartbeat, or sensitivity to cold. Inform your healthcare provider if your condition worsens or persists after several weeks of taking NP Thyroid.


  • Do not discontinue NP Thyroid without consulting your healthcare provider, as thyroid replacement treatment is typically taken for life.
  • Do not change brands of thyroid hormone without consulting your healthcare provider.

Common Side Effects:

  • Increased sweating
  • Sensitivity to heat
  • Nervousness
  • Mood swings
  • Tiredness
  • Diarrhea
  • Tremors
  • Headache
  • Shortness of breath

Inform your healthcare provider if you experience any of these common side effects.

Serious Side Effects:

  • Indications of high thyroid hormone levels may include chest pain, fast/pounding/irregular heartbeat, swelling of hands/ankles/feet, and seizures

In the case of these serious effects, seek medical help immediately.

Allergic Reactions:

While rare, a serious allergic reaction to NP Thyroid may occur. Symptoms of a serious allergic reaction may include:

  • Rash
  • Itching/swelling (especially of the face/tongue/throat)
  • Severe dizziness
  • Trouble breathing

If you notice any of these symptoms, seek immediate medical help.

Thyroid hormones should be used with great caution in circumstances where the integrity of the cardiovascular system, particularly the coronary arteries, is suspected. This includes patients with angina pectoris or the elderly, in whom there is a greater likelihood of occult cardiac disease.

In patients with concomitant diabetes mellitus or adrenal cortical insufficiency, the use of NP Thyroid may worsen the intensity of their symptoms. Appropriate adjustments of therapeutic measures directed at these concomitant endocrine diseases are required.

Patients stabilized on oral anticoagulants who require thyroid replacement therapy should be closely monitored when thyroid treatment is initiated. A reduction in anticoagulant dosage will likely be required if a patient is truly hypothyroid.

In infants, excessive doses of NP Thyroid may lead to craniosynostosis.

Partial loss of hair may be experienced by children in the first few months of therapy, but it is usually transient.

NP Thyroid is contraindicated in patients with uncorrected adrenal insufficiency, untreated thyrotoxicosis, and hypersensitivity to any component of the product.

NP Thyroid may interact with other medications. Consult your healthcare provider before making any changes to your medication regimen.

Inform your healthcare provider about any other medical conditions you may have, especially heart disease, diabetes, blood clotting problems, and adrenal or pituitary gland problems.
