View full FDA label ↗
Liomny is a medication used to treat hypothyroidism, which is when your thyroid doesn't produce enough hormones, and it can also help manage certain types of thyroid cancer. It works by providing your body with a hormone called triiodothyronine (T3), which helps regulate many important functions in your body. You take it by mouth once a day, starting with a low dose of 25 micrograms, which can be increased based on your response, but the maximum usual dose is 75 micrograms daily. It's important to know that Liomny should not be taken if you have untreated adrenal insufficiency, as this can lead to serious health issues. Additionally, if you're switching from another thyroid medication, like levothyroxine, you should stop that medication before starting Liomny and begin with a lower dose.
