NP Thyroid is a medication used to treat hypothyroidism, which is when your thyroid gland doesn't produce enough hormones. It works by providing the hormones your body needs to regulate metabolism and energy levels. You typically take it as a tablet, starting with a dose of 30 mg, which can be increased by 15 mg every 2 to 3 weeks, with most patients needing between 60 to 120 mg per day. It's important to know that this medication should not be used for weight loss, as taking it for that purpose can lead to serious health risks. Additionally, if you have untreated adrenal problems or are allergic to any of its ingredients, you should avoid using it.
