Unithroid is a medication used to treat hypothyroidism, which is when your body doesn't produce enough thyroid hormone, and it can also help manage certain types of thyroid cancer. It works by providing your body with a synthetic form of thyroid hormone that helps regulate your metabolism and energy levels. You take it as a tablet once a day on an empty stomach, typically starting at a dose of about 1.6 micrograms per kilogram of body weight, with a maximum dose that usually doesn't exceed 300 micrograms per day. It's important to know that Unithroid should not be taken if you have untreated adrenal insufficiency, as this can lead to serious health issues. Additionally, certain medications, especially those that interfere with absorption like soybean-based infant formula, can affect how well Unithroid works, so it's best to take it at least four hours apart from those.
