LETHYROX 100MCG TABLET 100'S

How LETHYROX 100MCG TABLET 100'S Works

• LETHYROX 100MCG TABLET 100'S contains levothyroxine sodium, a synthetic form of thyroxine (T4), which is a naturally occurring thyroid hormone. The thyroid gland normally produces T4 and triiodothyronine (T3), which regulate the body's metabolism. LETHYROX is prescribed when the thyroid gland doesn't produce enough thyroid hormone, a condition known as hypothyroidism. This medication effectively replaces or supplements the missing thyroid hormone, restoring normal hormone levels and alleviating the symptoms of hypothyroidism.
• Once ingested, levothyroxine is absorbed into the bloodstream. A significant portion of T4 is then converted into T3, the more active form of the hormone, in various tissues and organs throughout the body, including the liver and kidneys. T3 binds to thyroid hormone receptors within cells, initiating a cascade of events that affect gene expression and protein synthesis. This, in turn, influences a wide range of physiological processes.
• The primary action of thyroid hormones is to stimulate metabolism. They increase the basal metabolic rate, which is the rate at which the body burns calories at rest. This leads to increased oxygen consumption and heat production. Thyroid hormones also play a crucial role in growth and development, particularly in the brain and nervous system. They are essential for normal brain development in infants and children and contribute to cognitive function and mood in adults.
• Furthermore, LETHYROX influences the metabolism of carbohydrates, fats, and proteins. It promotes the breakdown of carbohydrates, increases the mobilization of fats, and stimulates protein synthesis. Thyroid hormones also affect cardiovascular function by increasing heart rate and contractility. They regulate cholesterol levels and play a role in maintaining healthy bone density. By restoring adequate thyroid hormone levels, LETHYROX effectively reverses the symptoms of hypothyroidism, such as fatigue, weight gain, constipation, dry skin, and slowed heart rate. Regular monitoring of thyroid hormone levels is important to ensure that the dosage is appropriate and to avoid over- or under-replacement.

LETHYROX 100MCG TABLET 100'S may cause several side effects, although not everyone experiences them. Common side effects include: weight changes, headache, tremors, sweating, palpitations (fast or irregular heartbeat), nervousness, irritability, insomnia (difficulty sleeping), diarrhea, muscle weakness, and menstrual irregularities. Less common side effects can include: chest pain, heat intolerance, hair loss (usually temporary), vomiting, appetite changes, and leg cramps. Rare but serious side effects include: allergic reactions (rash, itching, swelling), seizures, and heart problems. If you experience any of these side effects, especially severe or persistent ones, consult your doctor immediately.

• If you miss a dose of LETHYROX 100MCG TABLET 100'S, 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 missed one.

• Keep LETHYROX 100MCG TAB 1X100 away from the reach of children and pets.
• Store LETHYROX 100MCG TAB 1X100 at room temperature.

• **Take LETHYROX 100MCG TABLET on an Empty Stomach:** For optimal absorption, administer LETHYROX 100MCG TABLET first thing in the morning, at least 30-60 minutes before your first meal. This consistent routine ensures the medication is properly absorbed into your bloodstream, maximizing its effectiveness in regulating your thyroid hormone levels. Food, especially certain items like fiber-rich foods, calcium, and iron supplements, can interfere with the absorption of levothyroxine.
• **Maintain Consistent Timing:** Establish a daily schedule for taking LETHYROX 100MCG TABLET and stick to it as closely as possible. This consistency helps maintain stable thyroid hormone levels in your body, leading to more predictable and effective symptom management. Set a reminder on your phone or incorporate it into your morning routine to avoid missing doses.
• **Avoid Certain Medications and Supplements Simultaneously:** Be mindful of other medications and supplements you're taking, as some can interfere with levothyroxine absorption. Calcium carbonate, iron supplements, antacids containing aluminum or magnesium, and certain cholesterol-lowering drugs (like cholestyramine) can reduce the effectiveness of LETHYROX 100MCG TABLET. If you need to take any of these, do so several hours before or after taking your levothyroxine dose. Always consult your doctor or pharmacist for guidance on potential interactions.
• **Regular Monitoring of Thyroid Hormone Levels:** Schedule regular blood tests with your healthcare provider to monitor your thyroid hormone levels (TSH, T4, and T3). These tests are crucial for ensuring that your LETHYROX 100MCG TABLET dosage is correctly calibrated to meet your individual needs. Dosage adjustments may be necessary based on these test results, especially during pregnancy, with changes in weight, or if you start or stop other medications.
• **Be Aware of Symptoms and Report Changes:** Pay close attention to any changes in your symptoms, whether they indicate hypothyroidism (fatigue, weight gain, constipation, dry skin, sensitivity to cold) or hyperthyroidism (anxiety, weight loss, rapid heartbeat, sweating, insomnia). Report any new or worsening symptoms to your doctor promptly, as they may indicate a need for dosage adjustment. Never adjust your dosage on your own without consulting your healthcare provider.
• **Store Properly:** Store LETHYROX 100MCG TABLET at room temperature, away from direct sunlight and moisture. Keep the medication in its original packaging to protect it from light exposure. Proper storage helps maintain the drug's stability and effectiveness. Avoid storing in the bathroom due to humidity.
• **Inform Healthcare Providers:** Always inform all your healthcare providers, including your doctor, pharmacist, and dentist, that you are taking LETHYROX 100MCG TABLET. This information is crucial for preventing potential drug interactions and ensuring that you receive appropriate medical care. Carry a list of all your medications with you.
• **What to do if you Miss a Dose:** If you miss a dose of LETHYROX 100MCG TABLET, take it as soon as you remember, unless it's almost time for your next scheduled dose. In that case, skip the missed dose and continue with your regular dosing schedule. Do not double your dose to make up for a missed one, as this can lead to an overdose and adverse effects.

• To ensure optimal absorption of LETHYROX, it is crucial to take it on an empty stomach, ideally 30-60 minutes before your first meal of the day. Certain substances can interfere with the absorption of levothyroxine, the active ingredient in LETHYROX.
• Avoid taking LETHYROX simultaneously with foods or supplements containing calcium, iron, or soy products, as these can significantly reduce the amount of levothyroxine your body absorbs. If you take these substances, separate their intake from LETHYROX by at least 4 hours.
• Dietary fiber can also affect levothyroxine absorption. Maintain a consistent fiber intake to avoid fluctuations in your thyroid hormone levels. Consult your doctor if you make significant changes to your fiber consumption.
• Grapefruit juice and coffee might also affect the absorption of LETHYROX. While more research is needed, it's best to consume them separately from your medication.
• Always follow your doctor's instructions regarding food and medication interactions to maintain stable thyroid hormone levels and optimal health.
