When the thyroid gland does not produce enough hormones, the body’s metabolism slows down, leading to fatigue, weight gain, cold intolerance, and other health problems. Eltroxin 100 mcg is one of the most commonly prescribed thyroid hormone replacement medications. It helps restore balance and improve the quality of life for people living with hypothyroidism and related conditions.
In this article, we’ll discuss what Eltroxin is, the proper dosage, possible side effects, and essential safety tips. Whether you are just starting treatment or have been on thyroid medication for years, understanding how this medication works is key to effective and safe use.
What is Eltroxin?
Eltroxin is a brand name for levothyroxine sodium, a synthetic version of thyroxine (T4), a hormone usually produced by the thyroid gland. When the thyroid gland is underactive (hypothyroidism), the body lacks sufficient thyroid hormones, which play a critical role in metabolism, energy regulation, and overall organ function.
This medication comes in different strengths, such as Eltroxin 50mcg and 100 mcg, allowing doctors to tailor the dose based on individual needs.
Eltroxin uses include:
- Treating hypothyroidism (underactive thyroid)
- Managing goiter (enlarged thyroid gland)
- Supporting treatment in certain thyroid cancers
- Helping regulate hormone balance after thyroid surgery or radioactive iodine therapy
How Does Eltroxin Work?
Eltroxin replaces the thyroid hormone that the body cannot produce sufficiently. Once taken, levothyroxine is absorbed in the digestive system and converted into triiodothyronine (T3), the active form of the hormone. This hormone is crucial in maintaining energy, regulating body functions, and ensuring that every cell operates effectively. By restoring hormone levels, Eltroxin helps prevent complications associated with hypothyroidism, including fatigue, weight gain, and slowed organ function.
Key Functions of Eltroxin in the Body
- Metabolism – boosts energy and helps reduce sluggishness.
- Body temperature regulation – prevents sensitivity to cold.
- Growth and development – ensures proper cell and organ performance.
- Heart function – supports normal heart rate and blood circulation.
- Mental health – aids concentration, mood stability, and memory
Eltroxin Dosage Guidelines
The dosage of Eltroxin varies from person to person because thyroid hormone needs are highly individual. Factors such as age, body weight, severity of hypothyroidism, and the presence of other medical conditions play an essential role in recognizing the correct dose. Doctors usually start with a lower dose and gradually adjust it every 4–6 weeks based on blood test results (TSH, T3, T4) until the thyroid levels stabilize.
Most adults’ usual starting dose ranges between 50 and 100 mcg daily. Once the correct balance is reached, Eltroxin tablets are often used as a maintenance dose to keep thyroid function steady.
Special Considerations for Certain Patients
- Elderly patients – Often require a lower starting dose (such as 25–50 mcg daily) because their metabolism is slower and they may be more sensitive to medication.
- Patients with heart conditions (e.g., angina, arrhythmia, or prior heart attack) – Must start at the lowest possible dose, usually Eltroxin 25–50 mcg, since thyroid hormones increase heart rate and circulation. Starting too high could put unnecessary strain on the heart.
- Children and adolescents– require individualized dosing based on age and body weight since thyroid hormones are vital for growth and brain development.
- Pregnant women – May need higher doses of Eltroxin because pregnancy increases thyroid hormone requirements. Close monitoring is essential to protect both mother and baby.
How to Take Eltroxin
Eltroxin should be taken first thing in the morning on an empty stomach. Waiting 30–60 minutes before eating breakfast or drinking coffee or milk is essential because food and certain beverages can interfere with the medication’s absorption. Taking it consistently at the same time each day helps your body maintain steady thyroid hormone levels.
Avoiding Interactions
Some supplements and foods can affect how well Eltroxin works. Calcium, iron, soy products, and high-fiber meals can reduce its absorption, so it’s best to take these at least 4 hours apart from your Eltroxin dose. If you are on other medications, always check with your doctor or pharmacist to ensure no interactions.
Consistency is Key
To get the best results, Eltroxin should be taken every day at the same time without skipping doses. If you accidentally miss a dose, take it as soon as you remember unless it’s almost time for your next scheduled dose, never double up to make up for a missed tablet. Developing a daily routine, such as keeping your medication beside your bed, can help you remember.
Monitoring Your Thyroid Levels
Because thyroid hormone needs can change over time, your doctor may request regular blood tests, such as TSH and free T4, especially after starting or adjusting your dose. These tests ensure your hormone levels are within the healthy range and your medication works correctly. Once stable, blood tests are usually done every 6–12 months.
Eltroxin Side Effects
Like any medication, Eltroxin tablets can cause side effects, especially if the dosage is too high or too low.
Mild side effects may include:
- Nervousness or irritability
- Insomnia
- Increased appetite
- Mild hair loss (usually temporary in the first few months)
More serious side effects may include:
- Rapid or irregular heartbeat
- Chest pain
- Tremors
- Shortness of breath
- Excessive sweating
- Weight loss despite increased appetite
If any severe symptoms occur, contact your doctor immediately, as these may indicate that your dose needs adjustment.
Safety Tips When Taking Eltroxin
- Do not self-adjust the dose. Always follow your doctor’s prescription.
- Regular monitoring is essential. Thyroid hormone levels must be checked at least once or twice a year.
- Drug interactions. Please inform your doctor about other medications (e.g., antidepressants, blood thinners, diabetes medications) as they may interact with Eltroxin.
- Pregnancy and breastfeeding. Safe when prescribed, but doses may need adjustment during pregnancy.
- Consistency matters. Switching between different brands of levothyroxine should be avoided unless your doctor advises.
Eltroxin Price and Availability
The Eltroxin 100 mcg price may vary depending on the country, pharmacy, and whether you buy generic levothyroxine or branded Eltroxin. In many places, generic alternatives are more affordable while providing the same therapeutic benefit.
Some patients may choose for Eltroxin 100 mcg buy online options. While this may be convenient, always ensure you purchase from licensed pharmacies to avoid counterfeit medications.
Eltroxin 50mcg vs. 100 mcg: What’s the Difference?
Both strengths contain the same active ingredient, levothyroxine. The difference lies in the dosage:
- 50 mcg Eltroxin is typically prescribed as a starting dose, especially in patients who need gradual adjustment.
- 100 mcg Eltroxin is often used for long-term maintenance therapy in patients requiring higher hormone replacement.
Your doctor may sometimes prescribe a combination of different strengths to achieve the exact required dose.
Long-Term Benefits of Eltroxin
When taken correctly, the Eltroxin tablet helps:
- Improve energy and reduce fatigue
- Stabilize weight and metabolism
- Support heart and brain health
- Prevent complications like myxedema (severe hypothyroidism)
- Improve overall quality of life
Since hypothyroidism is usually a lifelong condition, many patients need to stay on Eltroxin medication indefinitely, with regular monitoring and dose adjustments.
