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.
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.

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.
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.
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.
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.
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.
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.

The dose of NP Thyroid depends on what you're taking it for. Your prescriber will adjust your dose based on how your body responds and your thyroid lab tests.
Hypothyroidism: The typical starting dose in adults is 30 mg by mouth daily. Your doctor may slowly increase the dose up to 120 mg a day, depending on what your body needs. Your dose might be lower if you have certain health conditions. Children’s doses are based on age and body weight.
Lowering TSH: The dose is calculated by your prescriber based on your body weight and is typically taken for 7 to 10 days.
Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur.

The following interactions have been selected on the basis of their potential significance and are not necessarily all-inclusive.

NP Thyroid usually doesn’t cause weight gain. In fact, it can sometimes lead to weight loss because changes in thyroid hormone levels can affect your metabolism and body weight. But you should never use this medication to try to lose weight. That's because taking it when you don’t need it or taking too much can be dangerous and cause serious heart or mood problems. Talk to your prescriber if you're worried about weight changes with this medication.
Yes, you can take NP Thyroid at night, but it's important to take it the same time every day to keep your routine consistent. Many people actually take it in the morning on an empty stomach, 30 to 60 minutes before eating, since food can affect how well your body absorbs the medication. If you prefer taking it at night, wait at least 2 hours after your last meal. Talk to your prescriber about the best time to take NP Thyroid.
NP Thyroid usually takes a few weeks to work. Most people begin to feel better after about 2 to 3 weeks. Your prescriber will check your thyroid levels with blood tests and might adjust your dose to make sure it’s working correctly.
Yes, NP Thyroid can sometimes cause some hair loss, especially in children. This usually happens when you first start treatment and is temporary. As your body gets used to the medication and your thyroid hormone levels return to normal, the hair loss often slows down or stops. If your dose is too high or too low, it can also affect your hair growth. Let your prescriber know if you notice ongoing or severe hair loss, since your thyroid levels might need to be checked or your dose adjusted.
Not exactly. NP Thyroid and Armour Thyroid are similar because both come from natural animal sources and contain the same thyroid hormones, T3 and T4. But they have different inactive ingredients. Some people might respond differently to one brand over the other. Speak with your prescriber if you have questions comparing the two medications.
No, NP Thyroid and levothyroxine aren't the same. NP Thyroid is a natural thyroid medication made from animal thyroid glands and contains two hormones, T3 and T4. Levothyroxine, on the other hand, is a lab-made form of only T4. Your body then converts that T4 into T3 as needed. Talk to your prescriber about the differences between these two medications.
