NP Thyroid
NP Thyroid is a prescription medication used to treat hypothyroidism in adults and children. It can also help with other thyroid-related problems. NP Thyroid is a natural thyroid hormone product that helps replace or add to the thyroid hormones your body doesn’t make enough of on its own. You usually take it once a day by mouth on an empty stomach. Side effects can happen if you take too much, like a fast heartbeat, feeling nervous, or being tired.
What is NP Thyroid?
What is NP Thyroid used for?
- Hypothyroidism (low thyroid hormone)
- Lowering thyroid-stimulating hormone (TSH) levels in people with other thyroid problems like goiters or thyroid cancer
How NP Thyroid works
NP Thyroid is a natural combination of two thyroid hormones: triiodothyronine (T3) and thyroxine (T4), which your thyroid gland normally makes. These hormones help control important functions like your metabolism, energy, heart rate, and body temperature.
If your body doesn’t make enough of these hormones, taking NP Thyroid can help bring your levels back to normal.

Pharmacist tips for NP Thyroid
- Take NP Thyroid on an empty stomach, usually first thing in the morning before eating. This helps your body absorb the medication better since food can affect how well it works.
- Get blood work done regularly while taking NP Thyroid. Your prescriber will use your thyroid hormone levels to adjust your dose and make sure the medication is working properly.
- Tell your prescriber or pharmacist about all other medications you take before starting NP Thyroid. It can affect how other medications work, so they might need to change your doses or schedule to prevent interactions.
- If you take cholesterol medications cholestyramine or colestipol, wait at least 4 to 5 hours between those medications and NP Thyroid. These cholesterol medications can lower how much thyroid hormone your body absorbs.
- If you have diabetes and are taking medications to lower your blood sugar levels, or if you're taking a blood thinner, your dose might need to be adjusted when you start NP Thyroid. Make sure to tell your prescriber about all your medications before you begin treatment.
- Talk to your prescriber if you notice signs of having too much thyroid hormone in your body. These can include shakiness, chest pain, or fast heartbeat. They might check your thyroid hormone levels and lower your NP Thyroid dose if needed.

Risks and warnings for NP Thyroid
NP Thyroid can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Not for weight loss
- Risk factors: Taking other medications for weight loss
NP Thyroid shouldn't be used for weight loss. It’s not recommended, safe, or effective for this purpose. If your thyroid levels are normal, taking normal doses won’t help you lose weight. Taking high doses of NP Thyroid can cause serious or life-threatening side effects, especially if used with other medications for weight loss.
Dangerously low stress hormone levels (adrenal crisis)
- Risk factors: Adrenal insufficiency | Addison's disease
In rare cases, you might have low thyroid hormones and low adrenal hormones at the same time. If your thyroid hormones are replaced first, your adrenal hormone levels can drop even lower and make you feel very sick. Your prescriber should check your adrenal hormone levels before prescribing NP Thyroid. Get medical help right away if you feel very tired, weak, dizzy, lose your appetite, or have stomach pain.
Worsening diabetes
- Risk factors: Taking diabetes medication
NP Thyroid can affect how your diabetes medications work and might change the dose you need. Be sure to check your blood sugar levels as directed by your prescriber. Talk to your prescriber if you notice blood sugar levels that are higher than usual. They might need to raise the dose of your diabetes medication.
Risk of heart problems
- Risk factors: Current heart conditions like chest pain | Older adults
Taking too much NP Thyroid can cause heart problems, especially if you're an older adult or already have certain heart conditions. Contact your prescriber or get medical care right away if you have a fast or irregular heartbeat, chest pain, or trouble breathing. Your prescriber might need to lower your dose if you start having new or worse heart symptoms while taking this medication.
Interactions with other medications
NP Thyroid can change the levels of certain medications in your body. These include oral anticoagulants, insulin, and oral diabetes medications. On the other hand, some medications can affect the levels of NP Thyroid in your system. These include certain cholesterol medications and oral contraceptives.
Before you start taking NP Thyroid, talk to your prescriber about all the medications you take. They might need to change your dose or help you plan when to take each one during the day. This helps your treatments work properly and lowers the risk of side effects or interactions.
