Levothyroxine is a medication commonly used to treat hypothyroidism, but it can also cause a range of side effects. It’s important to be aware of these potential side effects before starting treatment. Some common side effects of levothyroxine include hair loss, weight changes, anxiety, and heart palpitations. If you experience any of these side effects, be sure to consult with your doctor.
Overview of Levothyroxine
Levothyroxine is a synthetic form of the thyroid hormone thyroxine (T4). It is commonly prescribed to treat hypothyroidism, a condition where the thyroid gland does not produce enough hormones. Levothyroxine works by replacing the missing thyroid hormones in the body, helping to regulate metabolism and energy levels.
Levothyroxine is available in tablet form and is usually taken once a day on an empty stomach. It is important to follow the dosing instructions provided by your healthcare provider to ensure the medication is effective. Regular monitoring of thyroid hormone levels is also recommended to ensure the correct dosage of levothyroxine.
Common brand names for levothyroxine include Synthroid, Levoxyl, and Tirosint. It is important to take levothyroxine as prescribed and not to stop taking it without consulting your healthcare provider, as untreated hypothyroidism can lead to serious health problems.
What is levothyroxine?
Levothyroxine is a synthetic form of the thyroid hormone thyroxine, which is used to treat hypothyroidism (low thyroid hormone levels).
Thyroid hormone plays a crucial role in regulating metabolism, growth, and energy levels in the body. When the thyroid gland does not produce enough thyroid hormone, a condition known as hypothyroidism occurs. Levothyroxine works by replacing the missing thyroid hormone in the body, helping to restore normal thyroid function and improve symptoms of hypothyroidism.
How does levothyroxine work?
Levothyroxine is a synthetic form of the thyroid hormone thyroxine (T4). It works by replacing or supplementing the natural thyroid hormone in the body, which is essential for regulating metabolism, growth, and energy levels.
When a person has hypothyroidism (underactive thyroid), their thyroid gland does not produce enough thyroid hormone, leading to symptoms such as fatigue, weight gain, and depression. Levothyroxine helps to restore normal thyroid hormone levels in the body, relieving these symptoms and improving overall well-being.
