Levothyroxine is a synthetic form of the thyroid hormone thyroxine (T4) used to treat hypothyroidism. It helps restore normal thyroid hormone levels, improving symptoms and overall well-being.
Mechanism of Action
Levothyroxine replaces or supplements the thyroid hormone thyroxine (T4) in the body. This hormone is crucial for regulating metabolism, energy production, and overall growth and development.
Uses
- Hypothyroidism: Levothyroxine is used to treat underactive thyroid (hypothyroidism), helping to restore normal hormone levels and alleviate symptoms such as fatigue, weight gain, and depression.
Side Effects
Common side effects of levothyroxine include:
- Weight Changes: Some patients may experience weight loss or gain.
- Fatigue: Initial adjustment to the medication can cause fatigue.
- Hair Loss: Temporary hair loss may occur during the initial stages of treatment.
Precautions
To use levothyroxine safely, consider these precautions:
- Regular Monitoring: Regular thyroid function tests are necessary to ensure the correct dosage and monitor for effectiveness.
- Take on an Empty Stomach: For optimal absorption, take levothyroxine on an empty stomach, usually 30 minutes to an hour before breakfast.
- Avoid Certain Supplements: Calcium and iron supplements can interfere with levothyroxine absorption, so take them at least 4 hours apart.
