Lethyrox 75 Tablet

Lethyrox 75 Tablet is a tablet form of levothyroxine (thyroxine), a synthetic thyroid hormone used to replace or supplement the hormone your body normally makes. Each Lethyrox 75 Tablet contains 75 micrograms of levothyroxine. It belongs to the thyroid hormone replacement class and is used to treat hypothyroidism and other thyroid hormone deficiency states, including some cases after thyroid surgery or treatment.

How it works: Levothyroxine in Lethyrox 75 Tablet acts like the natural thyroid hormone T4, which helps control how fast your body uses energy. As a tablet, it is swallowed and absorbed in the stomach and small intestine, then converted in the body to the active hormone that supports metabolism, heart rate, temperature control, and normal growth and development.

Lethyrox 75 Tablet is a mid-strength levothyroxine tablet, higher than the 12.5, 50, and 88 microgram options but lower than the 100, 125, and 150 microgram tablets. A doctor may choose Lethyrox 75 Tablet when a patient needs a dose adjustment that is not as small as 50 micrograms and not as high as 88 or 100 micrograms, helping fine-tune thyroid levels more precisely. Because levothyroxine doses are individualized, this strength is typically selected after lab results and symptoms are reviewed rather than used as a one-size-fits-all starting dose.

• Hypothyroidism (underactive thyroid)
• Thyroid hormone replacement after thyroid surgery
• Thyroid hormone replacement after radioactive iodine treatment
• Long-term maintenance of thyroid hormone levels
• Selected cases of pituitary-related hypothyroidism

• Swallow Lethyrox 75 Tablet whole with a full glass of water, unless your doctor gives different instructions.
• Take it on an empty stomach, usually 30 to 60 minutes before breakfast, for best absorption.
• Take it at the same time every day so your thyroid levels stay steady.
• Do not switch brands or strengths on your own; even small dose changes can affect thyroid levels.
• Keep calcium, iron, antacids, and multivitamins several hours away from your Lethyrox 75 Tablet dose.
• If you miss a dose, take it when you remember unless it is almost time for the next dose; do not double up without medical advice.

Each Lethyrox 75 Tablet provides 75 micrograms of levothyroxine per tablet. It may be taken once daily, but the exact schedule and total daily dose are decided by the doctor based on age, weight, thyroid labs, heart status, and response to treatment. The maximum daily dose is not the same for everyone, and this strength should only be used in the amount prescribed for you.

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

Common side effects of Thyroxine / Levothyroxine may include:

• Headache
• Nervousness or feeling jittery
• Tremor
• Trouble sleeping
• Increased sweating
• Palpitations, especially if the dose is too high for you

• Lethyrox 75 Tablet is a relatively higher maintenance strength, so dose changes should be made only by a clinician and usually based on lab tests.
• Tell your doctor if you have heart disease, angina, high blood pressure, or a history of irregular heartbeat before taking this tablet.
• Use extra caution if you are older or frail, because too much levothyroxine can strain the heart.
• Do not take it at the same time as calcium, iron, bile acid binders, or antacids because they can reduce absorption.
• If you are pregnant or breastfeeding, your dose may need adjustment and monitoring; do not stop or change it on your own.
• This tablet is not for rapid weight loss and should not be used to improve energy in people with normal thyroid function.
• If you develop chest pain, severe palpitations, or signs of overdose, get urgent medical help.

• Calcium supplements and calcium-fortified products
• Iron supplements and multivitamins with iron
• Antacids containing aluminum or magnesium
