Levothyroxine

Levothyroxine is a medication used to treat hypothyroidism, a condition where the thyroid gland does not produce enough hormones. It works by providing the body with a synthetic version of a hormone called thyroxine, which helps regulate metabolism and energy levels. You take it as a tablet, usually once a day on an empty stomach, with the starting dose typically being 1.6 micrograms for every kilogram of your body weight, and the maximum dose is generally not more than 300 micrograms per day. It's important to know that this medication should not be taken if you have untreated adrenal insufficiency. Additionally, if you are taking biotin or biotin-containing supplements, you should stop them at least two days before having your thyroid hormone levels checked, as they can interfere with the test results.
