Indications 

NP-Thyroid is a prescription medication indicated for the management of hypothyroidism and goiter. It may be used alone or in combination with other medications to address these conditions. NP-Thyroid is classified as a Thyroid Product. 

Uses and Dosage 

Follow all instructions provided on your prescription label. Your doctor may periodically adjust your dosage to ensure the best possible outcome. Do not exceed or reduce the prescribed dose of NP Thyroid. 

While taking desiccated thyroid, frequent blood tests may be necessary. Continue using this medication as directed by your doctor, even if you feel fine. In most cases, thyroid medication will need to be taken for the remainder of your life. 

The dosage of thyroid hormones is customized for each patient based on their response and laboratory findings. Thyroid hormones are taken orally, and injectable levothyroxine sodium may be administered intravenously in acute or emergency situations, such as during total parenteral nutrition or treatment of myxedema coma when oral administration is not possible or desirable. Intramuscular injection is not recommended due to reported poor absorption. 

Contact your doctor immediately if you experience any symptoms of thyroid toxicity, such as chest pain, rapid or irregular heartbeats, excessive sweating or nervousness. 

If you are scheduled for surgery, inform your surgeon beforehand that you are using desiccated thyroid. You may need to discontinue the medication temporarily.
