Description
Levothyroxine is a synthetic form of thyroxine (T4), a hormone normally produced by the thyroid gland. It is prescribed to treat hypothyroidism, a condition in which the thyroid does not produce enough hormone to support the body’s normal metabolic functions. Thyroxine is essential for regulating energy, metabolism, temperature, and overall hormonal stability.
Low thyroid hormone levels can cause a range of symptoms, including fatigue, weight gain, depression, slow heart rate, sensitivity to cold, and memory difficulties. Levothyroxine replaces the missing hormone, helping the body return to a healthy metabolic balance. When taken consistently and at the correct dose, it can significantly improve energy, mental clarity, and physical well-being.
Levothyroxine is administered orally once daily, ideally in the morning on an empty stomach, at least 30 to 60 minutes before food or drink (except water). The dosage is individualized and based on factors like age, weight, thyroid hormone levels, and coexisting health conditions. Most people require ongoing, long-term treatment to maintain stable thyroid function.
Symptoms often begin to improve within one to two weeks, though it may take several weeks to feel the full benefit. Regular blood tests are important to ensure the correct dose and monitor long-term thyroid health.
Levothyroxine is generally well tolerated, but if the dose is too high, side effects like anxiety, insomnia, palpitations, or unintentional weight loss can occur. It is contraindicated in patients with untreated adrenal insufficiency, acute myocardial infarction, thyrotoxicosis, or known hypersensitivity to any component of the product.
