People with hypothyroidism have an underactive thyroid gland, so their body does not produce enough of these hormones.&nbsp;<\/p>\n\n\n\n<p>For people with goiter or thyroid cancer, the thyroid is growing too much. NP Thyroid works by telling the thyroid to stop producing its own hormones, which helps limit its growth.<\/p>\n\n\n\n<div class=\"quick-facts-card\">\n  <table class=\"quick-facts-table\">\n    <colgroup>\n      <col\/>\n      <col\/>\n    <\/colgroup>\n\n    <thead>\n      <tr>\n        <th colspan=\"2\">Quick Facts<\/strong><\/td>\n      <\/tr>\n    <\/thead>\n\n    <tbody>\n    <tr>\n    <td><strong>Common Brands<\/strong><\/td>\n    <td>NP Thyroid<\/td> \n  <\/tr>\n  <tr>\n    <td><strong>Drug Class<\/strong><\/td>\n    <td>Thyroid agents<\/td>\n  <\/tr>\n  <tr>\n    <td><strong>Generic Status<\/strong><\/td>\n    <td>No generic version available<\/td>\n  <\/tr>\n  <tr>\n    <td><strong>Availability<\/strong><\/td>\n    <td>Prescription only<\/td>\n  <\/tr>\n    <\/tbody>\n  <\/table>\n<\/div>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"dosing\">Dosing<\/h2>\n\n\n\n<p>NP Thyroid is taken daily by mouth. It comes in dosage strengths ranging from 15 mg to 120 mg. Dosing for NP Thyroid is highly individualized and based on your serum thyroid levels. Your provider will order regular testing of your thyroid, and may adjust your dosage depending on how your body responds.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Hypothyroidism (underactive thyroid): <\/strong>A typical starting dose is 30 mg taken daily by mouth, although your provider may recommend a lower dose if you have certain health conditions. After 2-3 weeks, your provider may order thyroid labs to check how the medication is working and adjust your dose if needed.&nbsp;<\/li>\n\n\n\n<li><strong>Goiter or thyroid cancer:<\/strong> The recommended dose is calculated by body weight and given for 7-10 days.<\/li>\n<\/ul>\n\n\n\n<div style=\"height:28px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p><em><strong>Note:<\/strong>&nbsp;Dosing information is educational only.

These risks may be higher in people who are older or have heart disease.<\/li>\n\n\n\n<li><strong>Weak bones (osteoporosis):<\/strong> Long-term over-replacement with thyroid hormone can accelerate bone loss, leading to reduced bone density and a higher risk of fractures, especially in postmenopausal women.<\/li>\n\n\n\n<li><strong>Adrenal crisis (low cortisol levels):<\/strong> In people with untreated adrenal insufficiency, starting thyroid medication can cause dangerously low stress hormone levels that require emergency attention.

Ask your healthcare provider if you should avoid soybean flour, cottonseed meal, walnuts, dietary fiber, and grapefruit juice while taking NP Thyroid.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"dose-timing-for-cholesterol-medications\">Dose Timing for Cholesterol Medications<\/h3>\n\n\n\n<p>Drugs like cholestyramine and colestipol can block absorption of NP Thyroid. It is recommended to take those medications and NP Thyroid at least 4\u20135 hours apart.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"take-considerations-for-diabetes-medications-and-blood-thinners-into-account\">Take Considerations for Diabetes Medications and Blood Thinners Into Account<\/h3>\n\n\n\n<p>The doses for these medications may need to be adjusted when you start taking NP Thyroid.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"schedule-regular-bloodwork\">Schedule Regular Bloodwork<\/h3>\n\n\n\n<p>Your healthcare provider may order thyroid labs to assess how well the medication is working for you.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"follow-storage-guidelines\">Follow Storage Guidelines<\/h3>\n\n\n\n<p>Keep the medication at room temperature (59\u00b0F to 86\u00b0F) in a tight container, protected from light and moisture.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"follow-missed-dose-guidelines\">Follow Missed Dose Guidelines<\/h3>\n\n\n\n<p>If a dose is missed, take it as soon as you remember, unless it\u2019s almost time for your next dose. In that case, skip the missed dose and take your next dose as usual. Do not double up on doses of NP Thyroid.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"drug-interactions\">Drug Interactions<\/h2>\n\n\n\n<p>NP Thyroid can interact with other medications, potentially altering their effectiveness or increasing the risk of side effects. For example:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Diabetes medications:<\/strong> Thyroid hormones can increase blood sugar levels, meaning insulin or oral diabetes medication dosages may need adjustment when starting NP Thyroid.<\/li>\n\n\n\n<li><strong>Blood thinners<\/strong>: Desiccated thyroid can amplify the effect of anticoagulants (like warfarin), potentially increasing the risk of bleeding. Your healthcare provider may need to adjust your blood thinner dosage.<\/li>\n\n\n\n<li><strong>Cholesterol medications<\/strong>: Drugs like cholestyramine (Questran) and colestipol (Colestid) bind to thyroid hormones and prevent absorption. They should be taken at least 4 to 5 hours apart from NP Thyroid.<\/li>\n\n\n\n<li><strong>Hormonal contraceptives<\/strong>: The estrogen in birth control pills or hormone replacement therapy can interact with NP Thyroid and may require a higher dose of NP Thyroid to be prescribed.<\/li>\n<\/ul>\n\n\n\n<p>Always give your doctor and pharmacist a complete list of all your medications, vitamins, and supplements to check for potential interactions.<\/p>\n\n\n\n<section class=\"telyrx-faq-section\" data-toc-title=\"FAQs\">\n\t<h2 class=\"telyrx-faq-heading\">FAQs<\/h2>\n\t\t<div class=\"telyrx-faq-items\">\n\t\t\n\n<details class=\"telyrx-faq-item\">\n\t<summary class=\"telyrx-faq-question\">\n\t\t<span class=\"telyrx-faq-question-text\">What is the difference between NP Thyroid and Synthroid?<\/span>\n\t\t<svg class=\"telyrx-faq-chevron\" width=\"20\" height=\"20\" viewBox=\"0 0 20 20\" fill=\"none\" aria-hidden=\"true\">\n\t\t\t<path d=\"M5 7.5L10 12.5L15 7.5\" stroke=\"currentColor\" stroke-width=\"2\" stroke-linecap=\"round\" stroke-linejoin=\"round\"\/>\n\t\t<\/svg>\n\t<\/summary>\n\t<div class=\"telyrx-faq-answer\">\n\t\t\n\n<p>NP Thyroid is a natural product made from animal thyroid glands and contains both T3 and T4 hormones.
