levotüroksiin

Levotüroksiin is a synthetic form of the thyroid hormone thyroxine (T4). It is a medication used to treat hypothyroidism, a condition where the thyroid gland does not produce enough thyroid hormones. Levotüroksiin is also used to treat or suppress certain types of goiters, which are enlarged thyroid glands, and to manage thyroid cancer.

The thyroid gland produces hormones that regulate metabolism, energy levels, body temperature, and heart rate. In hypothyroidism, the body's functions slow down due to a lack of these hormones. Levotüroksiin works by replacing the thyroxine that the thyroid gland is unable to produce sufficiently. It is absorbed into the bloodstream and then converted into its active form, triiodothyronine (T3), by the body's tissues.

Levotüroksiin is typically taken orally, usually once a day on an empty stomach, at least 30 minutes to an hour before breakfast. Consistent daily dosing is important for maintaining stable hormone levels. The dosage is determined by a doctor based on the patient's age, weight, the severity of the condition, and other individual factors. Blood tests are regularly performed to monitor thyroid hormone levels and adjust the dosage as needed.

Common side effects of levotüroksiin, if the dose is too high, can include symptoms of hyperthyroidism such as rapid heartbeat, nervousness, tremors, increased sweating, and weight loss. It is important to take levotüroksiin exactly as prescribed by a healthcare professional. Inform your doctor about any other medications or supplements you are taking, as some can interfere with levotüroksiin absorption or effectiveness.
