Eltroxin 25mcg (Thyroxine Sodium)

Eltroxin 25mcg contains Thyroxine Sodium (Levothyroxine). It is a commonly prescribed medicine used to treat Hypothyroidism – a condition in which the thyroid gland does not produce enough thyroid hormone. The tiny tablet plays an important role in helping to restore energy, growth, and hormone balance.

This comprehensive guide explores how Eltroxin functions, who is prescribed it, the correct way to use it, as well as its side effects, benefits, precautions, and safety over time.

What Is Eltroxin 25mcg?

Eltroxin is a trademark of Levothyroxine Sodium. This is a form of synthetic thyroid hormone T4 (thyroxine). Each Eltroxin25mcg tablet contains 25 micrograms of active thyroid hormone. It is designed to supplement or replace natural levels of thyroid hormone in the body.

Thyroid hormones play a key role in:

• Metabolic regulation
• Temperature control
• Brain development and function
• Cardiovascular health
• Menstrual cycles and fertility
• Growth and development in children

Eltroxin is available in multiple strengths (25mcg, 50mcg, 100mcg, etc.), but 25mcg can be used for the following conditions:

• Initial dose for patients with mild hypothyroidism
• Older adults or those with heart conditions (to avoid overcorrection)
• Dosage adjustment phase
• Children or individuals with lower body weight

Who Needs Eltroxin?

Eltroxin can be prescribed for individuals with Hypothyroidism, a condition in which the thyroid gland does not produce enough thyroid hormones. Some of the most common causes are:

• Hashimoto’s thyroiditis (autoimmune destruction)
• Post-thyroidectomy (surgical removal of the thyroid)
• Post-radioactive iodine therapy
• Congenital hypothyroidism (in newborns)
• Iodine deficiency
• Certain medications (like lithium or amiodarone)

Symptoms of Hypothyroidism:

• Fatigue
• Weight gain
• Cold intolerance
• Depression
• Constipation
• Dry skin and hair
• Slow heart rate
• Menstrual irregularities
• Memory problems
• Puffy face
• Hoarseness

Eltroxin helps to restore normal metabolism and relieve these symptoms.

How Eltroxin Works

Thyroid hormone exists primarily in two forms:

• T4 (Thyroxine) — inactive form, produced in large amounts by the thyroid
• T3 (Triiodothyronine) — active form, converted from T4 in tissues

The body converts synthesized T4 into T3 when needed. It helps to maintain the normal functions of energy production, metabolism, and cell activity.

As thyroid hormone levels stabilise, hypothyroidism symptoms begin to improve.

Dosage and Administration

General Guidelines:

• Dose: 25mcg is typically a starting dose, especially for:
  • Elderly patients

Monitoring and Follow-Up

To ensure that the dosage is correct, it’s important to monitor Thyroid hormone levels:

• TSH (Thyroid Stimulating Hormone) is the key blood test to track
