Active Ingredient (Generic Name):	Levothyroxine Sodium
Brand Name:	Eltroxin 25 mcg
Strength:	25 mcg
Dosage Form:	Tablet
Therapeutic Class:	Thyroid Hormone Replacement

Eltroxin 25 mcg contains levothyroxine sodium, a synthetic form of the thyroid hormone thyroxine (T4). It is primarily used as thyroid hormone replacement therapy in people with an underactive thyroid (hypothyroidism).

What Is Eltroxin 25 mcg?

Eltroxin 25 mcg is a thyroid hormone replacement medicine used to restore adequate levels of thyroid hormone in the body. It may be prescribed when the thyroid gland does not produce enough thyroxine.

The 25 mcg strength is commonly used as a starting or lower dose, depending on the individual’s thyroid hormone levels, age, medical history, and response to treatment. The appropriate dose should be determined by a healthcare professional.

How Does It Work?

Eltroxin contains levothyroxine, which is converted in the body to the active thyroid hormone T3. It helps replace the thyroid hormone that the body is unable to produce sufficiently.

Adequate thyroid hormone levels help support:

• Normal metabolism
• Energy production
• Heart and nervous system function
• Body temperature regulation
• Growth and development

How to Take Eltroxin 25 mcg

• Take Eltroxin exactly as prescribed by your doctor.
• It is generally taken once daily on an empty stomach, preferably in the morning.
• Take it with a full glass of water.
• Take it consistently at the same time each day.
• Avoid taking it together with certain medicines or supplements, particularly calcium or iron, as they can reduce levothyroxine absorption. Your healthcare provider may recommend separating these by several hours.
• Do not change the dose or stop treatment without medical advice.

Common Side Effects

Side effects are more likely when the dose is higher than required. Possible effects include:

• Headache
• Nervousness or anxiety
• Increased sweating
• Tremor
• Increased appetite
• Difficulty sleeping
• Diarrhea
• Increased heart rate
• Weight loss

If these symptoms persist or become troublesome, consult your healthcare provider.

Serious Side Effects

Taking too much levothyroxine can cause symptoms of excessive thyroid hormone, including:

• Rapid or irregular heartbeat
• Chest pain
• Severe nervousness or anxiety
• Significant tremors
• Shortness of breath
• Severe sweating
• Severe weakness

Seek medical attention if you experience severe or unusual symptoms, particularly chest pain or significant heart rhythm changes.

Contraindications and Precautions

Eltroxin should be used under medical supervision, particularly if you have:

• Heart disease or an irregular heartbeat
• High blood pressure
• Diabetes
• Adrenal gland problems
• Osteoporosis
• Other thyroid disorders

Tell your doctor about all medicines, vitamins, and supplements you take before starting treatment.

Important Notes

• Eltroxin is intended for thyroid hormone replacement, not for routine weight-loss treatment.
• Thyroid function should be monitored through blood tests such as TSH and, when appropriate, free T4.
• Your doctor may adjust the dose based on your laboratory results and symptoms.
• Take the medicine consistently because changes in timing or absorption can affect thyroid hormone levels.
• Do not take extra tablets to compensate for a missed dose unless specifically advised by your healthcare professional.
