## What is Eltroxin 100 mcg tablet

Eltroxin 100 mcg tablet is a prescription medication used to treat Hypothyroidism (an underactive thyroid gland) by restoring low thyroid hormone levels in the body. Its active ingredient is FDA-approved Levothyroxine or Thyroxine Sodium (100 mcg).

Thyroxine is a Thyroid Hormone Receptor (THR) agonist and a synthetic version of the naturally occurring thyroid hormone thyroxine (T4). GlaxoSmithKline (GSK) Pharmaceuticals Ltd. manufactures this Levothyroxine replacement therapy in a GMP-compliant facility.

After absorption, the active thyroid hormone, Thyroxine, is converted to the active hormone triiodothyronine (T3), which regulates metabolism, energy production, body temperature, heart function, and growth. Generally, it is taken once daily on an empty stomach, around 30-60 minutes before breakfast.

A missed dose, if any, should be taken as soon as remembered, unless it is close to the next dose. Get immediate medical attention for an overdose symptom, including a rapid heartbeat, chest pain, tremors, Anxiety, fever, or severe palpitations.

Although well-tolerated, Eltroxin, when taken in doses other than those required, can mimic symptoms of an overactive thyroid, such as headaches, muscle cramps, sweating, and Insomnia (trouble sleeping). Obtain urgent medical help for severe chest pain, irregular heartbeat, seizures, or confusion.

This Thyroxine 100 mcg tablet should not be used in patients with untreated Thyrotoxicosis (High thyroid hormone levels), uncorrected adrenal insufficiency, or a known hypersensitivity to Thyroxine. It should be used cautiously in patients with heart disease, Hypertension (High Blood Pressure), Diabetes, Osteoporosis, or elderly individuals.

Keep the pills at room temperature in a dry place protected from heat, moisture, and direct sunlight.

## What are the benefits of taking Eltroxin 100 mcg tablet

Eltroxin 100 mcg tablet includes Thyroxine Sodium, a synthetic version of T4. After absorption, T4 is converted into the active hormone T3 in body tissues. These hormones control metabolic processes, allowing cells to use oxygen and energy more efficiently.

When used regularly as prescribed, it helps to counteract the consequences of insufficient thyroid hormone production and maintain normal physiological processes.

The key benefits include:

Promotes optimal energy production while reducing fatigue.

Improves mental alertness, focus, and cognitive function.

Supports proper metabolism and nutrition utilization.

Encourages optimal cardiac and circulatory function.

Enhances overall physical performance and well-being.

Enables healthy skin, hair, and muscular function.

Improves quality of life by correcting hormone deficiency-related symptoms

## How quickly does Eltroxin 100 mcg tablet work

Eltroxin 100 mcg tablet typically begins working within 3–5 days of starting treatment, although noticeable improvement in Hypothyroidism symptoms might take 2–6 weeks. Blood levels of Thyroxine reach a steady state in about 4–6 weeks, at which point its full therapeutic effect is assessed.

Taking the tablet on an empty stomach, 30–60 minutes before breakfast, improves absorption, while food, calcium, iron supplements, and alcohol could affect its effectiveness. Individual metabolism, dosage, age, and underlying thyroid function also influence response time.

Consult a healthcare provider for personalized guidance on timing.

## Eltroxin 100 mcg tablet: Generic Thyroxine vs Levoxyl

Eltroxin 100 mcg tablet contains Thyroxine, the same FDA-approved active ingredient found in Levoxyl. Both medications replace deficient thyroid hormone and must meet the same bioequivalence standards for quality, safety, strength, and effectiveness established by regulatory authorities.

The primary difference is cost. Brand Levoxyl is generally more expensive, with a price range of $70.00-$90.00 for a 100-pill pack in the US, while generic Thyroxine medicines are available at around $0.90/100 pills at CheapMedicineShop. Eltroxin is manufactured in GMP-compliant facilities by GlaxoSmithKline Pharmaceuticals Ltd., which follows internationally recognized quality standards, including WHO-GMP certification.

The only differences are the manufacturer, packaging, tablet appearance, and inactive ingredients, which do not change the therapeutic action of levothyroxine when taken as prescribed.

## What are the side effects of Eltroxin 100 mcg tablet

Eltroxin 100 mcg is generally well-tolerated when taken at the prescribed dose. However, when consumed in higher doses, the medication can lead to the following side effects:

Headache

Nervousness

Irritability

Tremors

Insomnia

These effects often subside after dose adjustments or when you stop taking the medication. Contact your medical provider if symptoms persist or intensify.

## Safety Advice

Liver Disease

Liver patients should contact their doctor before taking the medication. The liver converts T4 into active T3. An impaired organ can affect this process or alter thyroid-binding proteins; hence, dose modifications and frequent monitoring are essential. The medication should be avoided in cases of severe liver issues.

Kidney Impairment

While Eltroxin is generally safe for individuals with kidney disease, kidney disorders could influence thyroid hormone levels and treatment response. This is why periodic thyroid function monitoring is important during therapy.

Pregnant and Breastfeeding women

Eltroxin 100 mcg is considered safe and often essential when prescribed during pregnancy and breastfeeding. Adequate thyroid hormone levels support maternal health and normal fetal development. However, dose adjustments may be needed during pregnancy or nursing.

Avoid

Alcohol has no significant direct interaction with Thyroxine, although persistent excessive drinking can decrease liver function and thyroid hormone metabolism. This, in turn, compromises the effectiveness of medication; hence, alcohol should be avoided while on treatment. Iron and calcium supplements, antacids and some cholesterol-lowering medicines can reduce the absorption of Thyroxine and should be taken at least 4 hours apart.

## FAQs

## What is Eltroxin 100 mcg used for?

Eltroxin 100 mcg contains Thyroxine, a synthetic form of the thyroid hormone thyroxine (T4). It is mainly prescribed to treat Hypothyroidism, helping restore normal hormone levels, improve metabolism, increase energy, and relieve symptoms, including fatigue, weight gain, and cold intolerance.

## What are the common side effects of Eltroxin?

When taken at the prescribed dose, Eltroxin is usually well tolerated. However, when taken in excess, the medication can mimic symptoms of overactive thyroid function (Hyperthyroidism). These include headache, nervousness, sweating, tremors, palpitations, increased appetite, Insomnia , Diarrhea, or unintended weight loss.

## Does Eltroxin increase cholesterol?

No, Eltroxin does not increase cholesterol levels. In fact, untreated Hypothyroidism often raises cholesterol.

## How long does Eltroxin take to start working?

Eltroxin begins replacing missing thyroid hormone soon after administration, but noticeable symptom improvement could take several weeks. Most patients start feeling better within 2 to 4 weeks, while full benefits and stable hormone levels might take 6 to 8 weeks.

## Can the Eltroxin 100 mcg tablet be taken with food?

No, Eltroxin 100 mcg tablet should not be taken with food. It works best when taken on an empty stomach because food can reduce its absorption. For maximum effectiveness, take it 30 to 60 minutes before breakfast, or as directed by your healthcare provider, for consistent results.

## What happens if I miss a dose of Eltroxin?

If you miss a dose of Eltroxin, take it as soon as you remember. However, if it is almost time for your next scheduled dose, avoid the missed dose and continue your regular schedule. Do not take two doses together.
