Who qualifies for levothyroxine

Our EU-licensed doctors look for specific criteria to determine if levothyroxine is appropriate for you. Typically, this medication is prescribed for individuals diagnosed with hypothyroidism, an underactive thyroid gland. This condition means your thyroid isn't producing enough hormones, leading to symptoms like fatigue, constipation, dry skin, and often, weight gain. The doctor will assess your medical history, current symptoms, and any previous diagnostic test results (such as TSH and T4 levels) provided in your questionnaire. It's crucial that you accurately provide all requested information for a thorough review. Levothyroxine is a hormone replacement therapy, and its suitability depends on a clear medical need for thyroid hormone supplementation.

What levothyroxine actually does (and doesn't do)

Levothyroxine is a synthetic version of the hormone thyroxine (T4), which your thyroid gland naturally produces. When you have hypothyroidism, your body doesn't make enough T4. Levothyroxine replaces this missing hormone, helping to restore your body's metabolic processes to a normal state. This can alleviate symptoms like fatigue, improve energy levels, and, over time, help with weight management by normalizing your metabolism. It's important to understand that while levothyroxine can help reverse thyroid-related weight gain, it is not a weight-loss drug itself. Its primary function is to correct the hormonal imbalance. Realistic timelines for noticeable improvement in symptoms can range from a few weeks to several months as your hormone levels stabilize and the dosage is fine-tuned by your doctor.

Side effects and when to stop

Like all medications, levothyroxine can have side effects, though it is generally well-tolerated when the dosage is correct. Most side effects occur if the dose is too high, mimicking symptoms of an overactive thyroid (hyperthyroidism). These can include heart palpitations, anxiety, tremors, insomnia, increased appetite, and weight loss. Less common side effects can include hair loss, especially early in treatment. If you experience any severe or persistent side effects, or symptoms of hyperthyroidism, you should contact a healthcare professional immediately. Never stop taking levothyroxine abruptly without consulting a doctor, as this can lead to a return of hypothyroid symptoms and potentially serious health issues.
