LETHYROX 75MCG TABLET 100'S

How LETHYROX 75MCG TABLET 100'S Works

• LETHYROX 75MCG TABLET 100'S contains levothyroxine sodium, a synthetic form of thyroxine (T4), which is a principal hormone secreted by the thyroid gland. This medication essentially replaces or supplements the body's natural thyroid hormone, ensuring that the body has enough thyroid hormone to function correctly. Thyroid hormones are crucial for regulating metabolism, which includes processes like energy production, protein synthesis, and fat breakdown.
• The thyroid gland produces two main hormones: thyroxine (T4) and triiodothyronine (T3). While the thyroid primarily releases T4, it is converted to the more active T3 in the peripheral tissues (liver, kidney, etc.). T3 is the hormone that binds to thyroid receptors inside cells and influences gene expression, thereby controlling metabolic processes. LETHYROX 75MCG TABLET 100'S, being a synthetic T4, is converted into T3, providing the necessary hormonal activity.
• Once ingested, levothyroxine is absorbed into the bloodstream. The absorption rate can vary depending on factors such as food intake, other medications, and individual physiology. It's generally recommended to take LETHYROX on an empty stomach, usually 30-60 minutes before breakfast, to maximize absorption. After absorption, levothyroxine binds to transport proteins in the blood, primarily thyroxine-binding globulin (TBG), albumin, and prealbumin. This binding helps to maintain a stable level of thyroid hormone in the circulation.
• The levothyroxine (T4) is then slowly converted into T3 by enzymes called deiodinases in various tissues. This conversion ensures a steady supply of the active hormone where it is needed. T3 then enters the cells and binds to thyroid hormone receptors in the nucleus. These receptors then interact with DNA to regulate the expression of specific genes. This gene regulation influences a wide range of physiological processes, including growth and development, body temperature, heart rate, and the metabolism of carbohydrates, fats, and proteins.
• In summary, LETHYROX 75MCG TABLET 100'S works by providing a synthetic form of T4, which the body converts to T3. This T3 then regulates gene expression, influencing metabolism and various bodily functions. By maintaining appropriate thyroid hormone levels, LETHYROX helps to alleviate the symptoms of hypothyroidism (underactive thyroid), such as fatigue, weight gain, and depression, and supports overall health and well-being.

Common side effects of LETHYROX 75MCG TABLET may include: weight changes, headache, tremor, sweating, increased appetite, nervousness, anxiety, irritability, difficulty sleeping (insomnia), palpitations, rapid heart rate, diarrhea, vomiting, abdominal cramps, menstrual irregularities, hair loss (usually temporary), muscle weakness, and fatigue. Less common but potentially serious side effects include: chest pain, shortness of breath, swelling of ankles or feet, seizures, and signs of an allergic reaction (rash, itching, swelling, severe dizziness, trouble breathing). This is not an exhaustive list; consult your doctor or pharmacist for a complete list and if you experience any unusual symptoms.

• If you miss a dose of LETHYROX 75MCG TABLET, take it as soon as you remember, unless it is almost time for your next dose. In that case, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for the one you missed.

• Keep LETHYROX 75MCG TAB 1X100 away from the reach of children and pets.
• Store LETHYROX 75MCG TAB 1X100 at room temperature.

• Take LETHYROX 75MCG TABLET 100'S on an empty stomach, ideally first thing in the morning, at least 30 minutes to an hour before your first meal. This ensures optimal absorption of the medication.
• Maintain consistency in timing. Take LETHYROX 75MCG TABLET 100'S at the same time each day to help maintain stable thyroid hormone levels in your body. This consistency is crucial for its effectiveness.
• Avoid taking LETHYROX 75MCG TABLET 100'S simultaneously with certain supplements and medications that can interfere with its absorption. These include calcium supplements, iron supplements, antacids containing aluminum or magnesium, and some cholesterol-lowering drugs. If you need to take any of these, do so several hours before or after taking your thyroid medication.
• Regular monitoring of thyroid hormone levels is essential while taking LETHYROX 75MCG TABLET 100'S. Your doctor will schedule blood tests to check your TSH (thyroid-stimulating hormone) levels and adjust your dosage as needed to ensure you're receiving the correct amount of medication. Follow your doctor's recommendations regarding blood tests diligently.
• Be aware of the symptoms of both hypothyroidism (underactive thyroid) and hyperthyroidism (overactive thyroid). If you experience symptoms such as fatigue, weight gain, constipation, or dry skin (hypothyroidism), or symptoms such as anxiety, weight loss, rapid heartbeat, or tremors (hyperthyroidism), notify your doctor. Dosage adjustments might be necessary. Do not abruptly stop taking this medication without consulting your healthcare provider.

• Take LETHYROX 75MCG TABLET on an empty stomach, preferably first thing in the morning, at least 30 minutes to an hour before food.
• Certain foods and supplements can interfere with the absorption of levothyroxine. These include: Soy products, Iron supplements, Calcium supplements and Antacids containing aluminum or magnesium.
• If you consume these substances, take LETHYROX 75MCG TABLET several hours before or after them to ensure proper absorption.
• Maintain consistency in your diet and timing of medication. Significant changes in fiber intake can affect levothyroxine absorption and may require dosage adjustments.
• Consult your doctor if you are unsure about potential food interactions or have specific dietary concerns.
