Lethyrox 150 Tablet

Lethyrox 150 Tablet is a prescription thyroid hormone medicine containing 150 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. It may also be used in some patients after thyroid surgery, after radioactive iodine treatment, or for other doctor-directed thyroid hormone replacement needs. Because Lethyrox 150 Tablet is a higher-strength tablet, it is usually selected when a clinician needs a full replacement or a larger step in dosing.

How it works: Levothyroxine works by replacing the thyroid hormone your body would normally make, helping regulate energy use, body temperature, heart rate, and metabolism. In tablet form, Lethyrox 150 Tablet is absorbed through the digestive tract and then converted in the body to the active hormone tissues need.

Lethyrox 150 Tablet is stronger than the lower strengths in the same brand, such as Lethyrox 12.5 Tablet, 50 Tablet, 75 Tablet, 88 Tablet, 100 Tablet, and 125 Tablet. This strength is typically used for patients whose thyroid dose has already been adjusted and who need a higher daily amount, so it is not usually the first tablet a new patient starts with. The tablet form allows convenient once-daily dosing and steady thyroid hormone replacement when taken consistently.

• Hypothyroidism
• Thyroid hormone replacement after thyroid surgery
• Replacement therapy after radioactive iodine treatment
• Goiter management in selected cases
• TSH suppression in doctor-directed thyroid conditions

• Take Lethyrox 150 Tablet exactly as prescribed, usually once daily.
• Swallow the tablet whole with a full glass of water; do not crush or chew unless your doctor tells you to.
• Take it on an empty stomach, ideally 30 to 60 minutes before breakfast.
• Keep it away from food, coffee, milk, iron, calcium, and antacids because they can reduce absorption.
• Take it at the same time every day to keep thyroid levels steady.
• If you miss a dose, follow your prescriber’s instructions; do not double up unless told to do so.

Lethyrox 150 Tablet provides 150 micrograms of levothyroxine per tablet. It is commonly taken once daily, but the exact schedule and maximum daily dose depend on your thyroid tests, age, heart health, and treatment goal; your doctor decides the dose for you. Because this is a higher-strength tablet, it should be used only when a clinician has determined that 150 micrograms is appropriate for your specific needs.

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