Introduction

Eltroxin 100 is a prescription-only thyroid medicine that contains 100 micrograms of levothyroxine per tablet. It is used to replace the hormone that an underactive thyroid gland cannot make in sufficient amounts. This guide explains what it is, how it works, and the safety rules that make treatment reliable, but it never replaces the personal instructions of your own doctor.

One point matters from the start: it is a hormone replacement, not a weight-loss product, and the dose must be set and adjusted by a doctor.

What is Eltroxin 100?

Eltroxin 100 is a brand of levothyroxine sodium, a synthetic form of the natural thyroid hormone thyroxine (T4). Each tablet delivers a 100 microgram strength, which the body converts to the active hormone T3. It is one of several tablet strengths, allowing a doctor to match the dose to each person.

• Class: thyroid hormone replacement.
• Access: prescription-only medicine.
• Goal: restore normal thyroid hormone levels confirmed by blood tests.

How Eltroxin 100 works

When the thyroid gland is underactive, the body slows down, causing tiredness, weight gain, cold intolerance and low mood. The levothyroxine in Eltroxin 100 tops up the missing hormone, allowing metabolism to return to a normal, steady level. Because the effect builds gradually, doctors check thyroid-stimulating hormone (TSH) after several weeks and adjust the dose accordingly.

Key benefits

• Reliable, well-established replacement for an underactive thyroid.
• Once-daily tablet that is easy to fit into a routine.
• Precise 100 microgram strength for accurate dosing.
• Long clinical experience when monitored with TSH tests.

These benefits depend on taking the exact dose your doctor prescribes and attending follow-up blood tests.

Common uses

A doctor may prescribe it for:

• Hypothyroidism (an underactive thyroid gland).
• Thyroid hormone replacement after thyroid surgery.
• Certain cases of goitre or thyroid conditions, as decided by the doctor.

It should never be used to try to lose weight in people with a normal thyroid.

Who it suits

It suits people whose blood tests confirm an underactive thyroid and whose doctor has chosen the 100 microgram strength as the right dose. It suits patients who can take the tablet consistently each morning and attend regular TSH checks. Older adults and people with heart disease usually start on a lower dose and build up slowly.

Who should avoid it

Do not take Eltroxin 100 unless a doctor has prescribed it for you. Extra caution or specialist advice is needed if you:

• Have an overactive thyroid or a normal thyroid (it is not for weight loss).
• Have heart disease, angina or an irregular heartbeat.
• Have adrenal gland problems that are not yet treated.
• Are pregnant — the dose often needs review, so tell your doctor.

How to use it

Take the tablets exactly as prescribed, usually one tablet once daily. Do not change the dose yourself, even if symptoms persist — only your doctor should adjust it after reviewing your TSH result.

• Swallow the tablet whole with water.
• Keep to the same daily routine so hormone levels stay steady.
• Do not stop suddenly without medical advice.

Best time to take it

Take it on an empty stomach, ideally in the morning at least 30 to 60 minutes before food, tea or coffee. Keep it separate from calcium and iron supplements and from antacids, because these bind the medicine and reduce absorption. A consistent daily timing helps keep your thyroid levels stable between blood tests.

Drug interactions

Several products can change how well Eltroxin 100 is absorbed or works. Tell your doctor and pharmacist about everything you take.

• Calcium and iron supplements — separate them by at least four hours.
• Antacids and some indigestion remedies.
• Certain cholesterol-lowering resins and some seizure medicines.
• Warfarin and diabetes medicines may need dose review.

Warnings & contraindications for Eltroxin 100

Used correctly, Eltroxin 100 is safe, but a few warnings are important:

• Do not self-adjust the dose — too much can cause palpitations, tremor and bone loss.
• It is not a weight-loss medicine and is dangerous if misused for that purpose.
• Report chest pain, fast or irregular heartbeat promptly.
• Pregnancy usually requires closer monitoring and dose changes.

Regular TSH blood tests guide safe long-term use.

When to see a doctor

Contact your doctor if you develop a fast or irregular heartbeat, chest pain, marked anxiety, tremor, excessive sweating, or ongoing tiredness and weight change despite treatment. Also see your doctor before making any change to your dose and whenever you become pregnant, as your thyroid needs may rise.

Eltroxin 100 — Frequently asked questions

Q: Is Eltroxin 100 a weight-loss drug?
A: No. It is thyroid hormone replacement. Using it for weight loss with a normal thyroid is unsafe and can harm the heart and bones.

Q: When is the best time to take it?
A: On an empty stomach in the morning, 30 to 60 minutes before food and away from calcium or iron.

Q: Can I stop once I feel better?
A: No. Hypothyroidism is usually lifelong, so keep taking it and never stop without your doctor.

Q: How is the dose decided?
A: Your doctor sets and titrates the dose using TSH blood tests, not by symptoms alone.

Q: What if I miss a dose?
A: Take it when you remember the same day; if it is nearly the next day, skip it. Do not double up.
