View full FDA label ↗
NP Thyroid is a medication used to treat hypothyroidism, a condition where the thyroid gland doesn't produce enough hormones, and it can also help manage certain types of goiters and thyroid cancer. It works by providing the hormones that the thyroid normally makes, which helps regulate metabolism and energy levels in the body. You take it as a tablet, usually starting with a dose of 30 mg, which can be increased by 15 mg every 2 to 3 weeks, with most people needing between 60 to 120 mg per day. It's important to know that this medication should not be used for weight loss, as it can lead to serious side effects, especially when combined with other weight-loss drugs. Additionally, if you have untreated adrenal insufficiency or are allergic to any ingredients in the medication, you should not take it.
