Thyronorm 100 mcg is a prescription medication containing levothyroxine sodium, a synthetic form of the thyroid hormone thyroxine (T4). It is used to treat hypothyroidism, a condition where the thyroid gland does not produce enough thyroid hormones, leading to symptoms like fatigue, weight gain, and depression. Thyronorm 100 mcg helps restore normal hormone levels, improving metabolism, energy levels, and overall well-being. The dosage is typically determined based on individual needs and is taken once daily, preferably on an empty stomach in the morning. Regular monitoring of thyroid function tests (TSH, T3, T4) is essential to ensure the correct dosage. Always follow your doctor’s instructions when using Thyronorm to avoid under- or over-treatment.
