Thyrosec 125 mcg Tablet

Thyrosec 125 mcg Tablet is a prescription tablet containing 125 micrograms of thyroxine, also called levothyroxine, a synthetic thyroid hormone. 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. Thyrosec 125 mcg Tablet helps replace the missing hormone so the body can maintain normal energy, metabolism, temperature, and growth functions. This strength is intended for patients whose doctor has determined they need a higher replacement dose.

How it works: Levothyroxine is identical to the main hormone made by the thyroid gland, so Thyrosec 125 mcg Tablet replaces what the body is missing. After the tablet is absorbed, it helps normalize thyroid hormone levels and supports the body's energy use, heart function, and metabolism.

Thyrosec 125 mcg Tablet is a higher-strength levothyroxine tablet than Thyrosec 25 mcg Tablet, so it is not the usual starting dose for most people. A clinician may choose this strength when a lower dose is no longer enough, when a patient is already titrated upward, or when a specific maintenance dose is needed based on blood tests. Because it delivers more hormone per tablet, it may produce stronger effects and a greater risk of over-replacement if used without medical guidance.

• Treatment of hypothyroidism
• Thyroid hormone replacement therapy
• Support after thyroid removal or thyroid underactivity when prescribed
• Management of certain thyroid hormone deficiency states as directed by a doctor

• Swallow Thyrosec 125 mcg Tablet whole with a full glass of water unless your doctor instructs otherwise.
• Take it on an empty stomach, ideally 30 to 60 minutes before breakfast or other food.
• Take it at the same time each day to keep thyroid levels steady.
• Do not change to a different levothyroxine product or strength without medical advice, because dose needs can differ.
• Separate this tablet from calcium, iron, antacids, or multivitamins by several hours if your doctor advises.
• If you miss a dose, follow your prescriber’s instructions rather than doubling up on your own.

Each Thyrosec 125 mcg Tablet contains 125 micrograms of levothyroxine. It is usually taken once daily, but the exact schedule and maximum daily amount depend on your thyroid tests, age, weight, and heart health; your doctor determines the right dose and may adjust it gradually. Do not take more than prescribed, because 125 mcg is a relatively high replacement strength for some patients.

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

Common side effects of Thyroxine / Levothyroxine may include:

• Palpitations or feeling your heartbeat more strongly, especially if the dose is too high
• Nervousness or tremor
• Headache
• Trouble sleeping
• Increased sweating or heat intolerance
• Temporary changes in appetite or weight

• Thyrosec 125 mcg Tablet is a higher strength, so it should only be used after a doctor has assessed your thyroid levels and needs.
• Use extra caution if you have heart disease, angina, arrhythmias, or a history of heart attack, because thyroid hormone can strain the heart.
• Do not use it to lose weight or boost energy if you do not have hypothyroidism; misuse can be dangerous.
• Tell your doctor if you are pregnant, planning pregnancy, or breastfeeding, because dose needs may change.
• Keep calcium, iron, antacids, bile acid sequestrants, and some supplements away from the dose because they can reduce absorption.
• If you have diabetes, your blood sugar medicines may need adjustment when thyroid hormone is started or changed.
• Do not stop Thyrosec 125 mcg Tablet suddenly unless your doctor tells you to.

• Calcium supplements and dairy-heavy meals can reduce absorption if taken too close to the dose.
• Iron supplements and multivitamins can interfere with levothyroxine absorption.
• Antacids and acid-reducing medicines may change how well this tablet is absorbed.
• Warfarin and other blood thinners may work differently when thyroid hormone dose changes.
• Certain diabetes medicines may need closer monitoring because thyroid treatment can affect blood sugar control.
