Thyroid hormone✓ FDA-verified
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 body with the thyroid hormones it needs to regulate metabolism and energy levels. You typically take it as a tablet, starting with a dose of 30 mg daily, which can be increased by 15 mg every 2 to 3 weeks, with most patients needing between 60 to 120 mg each day. It's important to know that this medication should not be taken if you have untreated adrenal insufficiency or active hyperthyroidism. Additionally, if you're taking sedatives or anesthetics, be cautious, as they can affect how your body responds to the medication.
