Eltroxin 100 mcg Tablet

Eltroxin 100 mcg Tablet is a prescription thyroid hormone medicine that contains 100 micrograms of thyroxine (levothyroxine) in each tablet. It belongs to the thyroid hormone replacement class and is used to treat hypothyroidism, a condition where the thyroid gland does not make enough hormone. Eltroxin 100 mcg Tablet may also be prescribed to help suppress thyroid-stimulating hormone in certain thyroid conditions when a doctor decides it is appropriate. This specific 100 mcg tablet is a full-strength maintenance dose for many adults, not the usual starting dose for everyone.

How it works: Levothyroxine in Eltroxin 100 mcg Tablet acts like the natural thyroid hormone your body normally makes. By replacing missing hormone, the tablet helps regulate metabolism, energy use, heart function, and body temperature.

Eltroxin 100 mcg Tablet is a higher-strength option compared with 25 mcg, 50 mcg, 75 mcg, and 88 mcg tablets, so it is often chosen when a patient needs a larger daily thyroid hormone dose after evaluation. Because thyroid replacement is adjusted carefully, this strength may suit people whose dose has been titrated upward over time, rather than someone just starting treatment. Some patients feel the effect gradually over days to weeks, but the right dose is chosen to match lab results and symptoms.

• Treatment of hypothyroidism
• Thyroid hormone replacement therapy
• TSH suppression in selected thyroid disorders
• Long-term maintenance after dose titration

• Swallow Eltroxin 100 mcg Tablet whole with a full glass of water unless your doctor tells you otherwise.
• Take it on an empty stomach, usually 30 to 60 minutes before breakfast, for best absorption.
• Try to take it at the same time every day.
• Do not take it with calcium, iron, antacids, or multivitamins at the same time; separate them by several hours.
• Do not change brands, dose, or tablet strength on your own because thyroid doses are very individualized.
• If you miss a dose, follow your prescriber’s instructions; do not double up unless specifically told to do so.

Each Eltroxin 100 mcg Tablet provides 100 micrograms of levothyroxine, so it is a relatively strong tablet compared with lower-strength tablets in the same brand. It is usually taken once daily, but the exact dose and schedule are determined by the doctor based on thyroid labs, age, weight, heart health, and how you respond. The maximum daily amount is not the same for everyone, so never exceed the amount your prescriber has set for you.

Do not change your dose or stop the medicine without speaking to your doctor.

Common side effects of Thyroxine / Levothyroxine may include:

• Nervousness or feeling jittery
• Tremor
• Headache
• Insomnia
• Sweating
• Increased appetite
• Fast heartbeat or palpitations, which may be more noticeable if the 100 mcg dose is too high for you

• This 100 mcg strength is a higher dose, so it should be used only after a doctor has assessed your thyroid levels and treatment needs.
• Use extra caution if you have heart disease, high blood pressure, atrial fibrillation, or a history of heart rhythm problems.
• Tell your clinician if you are pregnant, breastfeeding, or planning pregnancy, because thyroid dose needs often change.
• Do not take it at the same time as calcium, iron, aluminum-containing antacids, or bile acid binders because they can reduce absorption.
• If you have diabetes, levothyroxine may change blood sugar control and your diabetes medicines may need adjustment.
• Alcohol does not directly change the tablet, but heavy use can complicate thyroid management and overall health.
• Be careful if you notice dizziness, shakiness, or a racing heart before driving or using machinery.

• Warfarin and other blood thinners may have stronger effects after starting or changing levothyroxine.
• Calcium supplements, iron supplements, and multivitamins can block absorption.
• Antacids and acid-lowering medicines may interfere with how well the tablet is absorbed.
• Diabetes medicines may need dose changes because thyroid hormone can affect blood sugar control.
• Some seizure medicines and rifampin can lower levothyroxine levels in the body.
