How Levothyroxine Works

The thyroid gland regulates metabolism through T4 and T3 hormones. In hypothyroidism, the gland fails to produce enough hormones. Levothyroxine supplements T4, which the body converts into T3, restoring normal thyroid activity and improving energy, weight control, and mental clarity.

Key Medical Uses

  • Hypothyroidism: Corrects low thyroid hormone levels due to Hashimoto’s thyroiditis, thyroid removal, or iodine therapy.
  • Thyroid-stimulating hormone (TSH) suppression: Helps prevent tumor regrowth after thyroid cancer surgery.
  • Goiter (enlarged thyroid): Reduces non-cancerous thyroid swelling.
  • Congenital hypothyroidism: Essential treatment for infants with thyroid deficiency.

Levothyroxine: Dosage and Administration

Levothyroxine is available in tablet, capsule, liquid, and injectable forms.

  • Adults (under 50, no heart disease): 25–50 mcg daily, adjusted to 75–125 mcg.
  • Older adults or heart conditions: Start low (12.5–25 mcg).
  • Children: Weight-based (≈ 1.6 mcg/kg/day).
  • Pregnancy: May need 25–50% higher dose.

Take once daily on an empty stomach, 30–60 minutes before breakfast, with water. Avoid calcium, iron, and antacids within 4 hours—they interfere with absorption.

Levothyroxine: Side Effects

At proper doses, Levothyroxine is well-tolerated. Problems arise when doses are too high or too low.

  • Overdose (hyperthyroid-like symptoms): Rapid heartbeat, anxiety, weight loss, sweating, tremors.
  • Underdose: Fatigue, weight gain, dry skin, depression, and cold intolerance.
  • Rare reactions include chest pain or allergic rash—seek immediate care.

Levothyroxine: Drug Interactions

  • Calcium & iron supplements: Reduce absorption (separate by 4 hours).
  • Antacids and PPIs: Lower effectiveness.
  • Estrogen therapy: May increase binding proteins, requiring dose adjustment.
  • Warfarin: May enhance blood-thinning effect.

Levothyroxine: Brand Names

Common global brands include Synthroid®, Levoxyl®, Tirosint®, Unithroid®, and Euthyrox®. Always consult your healthcare provider before switching brands, as absorption can differ.

Important Safety Information

  • Do not stop Levothyroxine abruptly—it is a lifelong therapy for most patients.
  • Long-term overtreatment can cause bone loss (osteoporosis) or heart issues.
  • Monitor TSH levels regularly (every 6–8 weeks initially, then annually once stable).
  • It is safe during pregnancy and breastfeeding under medical supervision.
