Thyroxine

DRUGS FOR HYPOTHYROIDISM

Uses of Thyroxine

  • Thyroxine Sodium is used to treat hypothyroidism, a condition characterized by low levels of thyroid hormone, leading to a slowed metabolism. 
  • This hormone is essential for normal growth, development, and regulating the body's energy use (metabolic rate). It also plays a role in digestion, heart and muscle function, brain development, and bone health.

Side effects of Thyroxine

  • Increased appetite
  • Weight loss
  • Diarrhoea
  • Muscle spasm
  • Headache

How Thyroxine works

Thyroxine Sodium works by controlling DNA transcription and protein synthesis. Triiodothyronine (T3) and L-thyroxine (T4) enter the cell nucleus and attach to thyroid receptor proteins linked to DNA. This complex activates gene transcription and the production of messenger RNA and cytoplasmic proteins. The main physiological effects of thyroid hormones are primarily generated by T3, with the majority (about 80%) formed from T4 through deiodination in peripheral tissues.

Caution In Other Conditions

  • Patients with heart issues, and diabetes should exercise caution while taking this medicine.

Special Dietary & Lifestyle Recommendation

  • The thyroid gland relies on iodine to produce its hormone, so it's important to include iodized table salt in your diet. However, excessive intake can lead to hyperthyroidism, so moderation is key. Additionally, individuals with hypothyroidism may benefit from a balanced diet rich in nutrients and a regular dose of Thyroxine Sodium including a variety of vegetables in your meals can be beneficial.
  • Hypothyroidism often results in calcium and Vitamin D deficiencies, so incorporating calcium-enriched foods is recommended. Since hypothyroidism can slow metabolism, increasing protein intake with foods like eggs, milk, and pulses may help boost metabolism. Engaging in daily yoga and aerobics exercises can promote relaxation and enhance metabolism.
  • For those with hypothyroidism, prioritizing vegetables, fruits, and lean meats is advisable as these foods are low in calories and may aid in weight management. It's important to avoid Goitrogens, which can interfere with thyroid function. Foods like soy products, cabbage, broccoli, kale, and spinach should be consumed in moderation to support thyroid health.
