Thyrosec 25 mcg Tablet

Thyrosec 25 mcg Tablet is a thyroid hormone replacement medicine containing levothyroxine (thyroxine) 25 mcg in each tablet. It is used to replace or supplement low thyroid hormone levels when the thyroid gland does not make enough hormone on its own. This prescription medicine belongs to the thyroid hormone class and is commonly used for hypothyroidism, certain goiter-related conditions, and thyroid hormone replacement after thyroid treatment when prescribed by a clinician.

How it works: Levothyroxine is a synthetic form of the thyroid hormone T4, and Thyrosec 25 mcg Tablet replaces what the body is missing. After the tablet is swallowed and absorbed, it helps regulate metabolism, energy use, body temperature, and many body functions that slow down when thyroid hormone is low.

Thyrosec 25 mcg Tablet is a low-dose strength, which makes it useful when a doctor wants to start thyroid replacement carefully or adjust treatment in small steps. Compared with the higher-strength Thyrosec 125 mcg Tablet, the 25 mcg tablet is less likely to cause an abrupt increase in thyroid hormone levels and may be chosen for older adults, people with heart disease, or patients who need a cautious dose increase.

• Hypothyroidism
• Thyroid hormone replacement
• Goiter management when prescribed
• Support after thyroid surgery or treatment
• Certain thyroid suppression regimens as directed by a doctor

• Swallow Thyrosec 25 mcg Tablet whole with a full glass of water unless your prescriber gives different instructions.
• Take it on an empty stomach, usually 30 to 60 minutes before breakfast.
• Take it at the same time every day to help keep thyroid levels steady.
• Do not take it at the same time as calcium, iron, antacids, or bile acid sequestrants; separate dosing as directed by your pharmacist or doctor.
• If you miss a dose, take it when remembered unless it is close to the next dose; do not double up without medical advice.
• This tablet is not meant to be chewed or crushed unless your doctor or pharmacist says it is acceptable.

Each Thyrosec 25 mcg Tablet provides 25 micrograms of levothyroxine per tablet, and the exact dose is individualized by the prescriber. It may be taken once daily, which is the usual schedule for levothyroxine tablets, but the total amount per day depends on your labs, age, weight, and heart health. Do not increase your dose on your own; the doctor decides the right starting dose and any adjustments, and the maximum daily dose varies by patient rather than by this tablet alone.

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

• Do not take it with food, coffee, soy formula, or high-fiber meals because absorption may be reduced.
• Use caution if you take calcium, iron, magnesium, antacids, sucralfate, or bile acid binders because they can block absorption.
• Inform your clinician if you have diabetes, as thyroid hormone can change blood sugar control and insulin or diabetes medicine needs may shift.

• Do not stop or change the dose suddenly unless your prescriber instructs you to do so.
