Dr. Marina Sharoyko is a medical specialist in clinical pharmacology and internal medicine, with additional expertise in cardiology and physiology.

Eltroxin is a synthetic form of thyroxine (levothyroxine), a hormone that plays a vital role in regulating the body’s metabolism, energy production, and overall hormonal balance. It is prescribed to treat hypothyroidism, a condition in which the thyroid gland does not produce enough natural thyroid hormone.

When thyroid hormone levels are low, the body’s systems slow down. Common symptoms include fatigue, weight gain, cold sensitivity, dry skin, depression, and difficulty concentrating. Eltroxin works by restoring normal levels of thyroxine in the blood, helping to reverse these symptoms and support normal physiological function.

Eltroxin is taken orally, usually once a day on an empty stomach, ideally in the morning. Consistent daily use helps stabilize hormone levels, and most people begin to notice improvements in energy, mood, and metabolism within a few weeks. The dosage is tailored to the individual based on thyroid hormone levels, age, weight, and other medical conditions.

Most patients begin to notice improvements in energy, mood, and metabolism within 1 to 2 weeks, although full therapeutic effect may take several weeks. The dose is individualized based on TSH and free T4 levels, as well as the patient’s age, body weight, and comorbid conditions.

Long-term treatment with Eltroxin is often necessary, as hypothyroidism is typically a chronic condition. Regular blood tests are required to monitor thyroid function and ensure the correct dose is being maintained.

Eltroxin is generally well tolerated. Mild side effects may occur if the dose is too high, including restlessness, rapid heartbeat, sweating, or insomnia, signs of too much thyroid hormone. It should not be used in cases of untreated adrenal insufficiency or in people allergic to any of its ingredients.
