Product Description
Levothyroxine 100mcg tablets are a synthetic form of the thyroid hormone thyroxine, used to treat an underactive thyroid gland (hypothyroidism). It replaces the hormone that the thyroid gland is unable to produce naturally.
How Levothyroxine Works:
The thyroid gland produces thyroxine, a hormone that regulates metabolism, heart rate, body temperature, and other vital functions. When the thyroid gland doesn't produce enough thyroxine, various bodily processes slow down, leading to hypothyroidism. Levothyroxine supplements the body's natural thyroid hormone production, restoring proper function.
Uses:
Levothyroxine 100mcg tablets are used to treat:
- Hypothyroidism: This condition occurs when the thyroid gland doesn't produce enough thyroid hormone. Symptoms include fatigue, weight gain, constipation, dry skin, and sensitivity to cold.
- Other Thyroid Disorders: Levothyroxine is also used to treat other thyroid disorders, such as thyroid cancer.
- Congenital Hypothyroidism: This condition is present at birth and can cause developmental delays if left untreated. Levothyroxine is essential for normal growth and development in children.
Dosage and Administration:
The dosage of levothyroxine varies depending on the individual's age, weight, and the severity of their hypothyroidism. It is typically taken by mouth, usually once daily on an empty stomach, 30 minutes to 1 hour before breakfast. It's important to swallow the tablet whole and not crush, chew, or break it.
Important Precautions:
- Do not stop taking levothyroxine suddenly without consulting your doctor. Stopping abruptly can cause serious health problems.
- Pregnancy and Breastfeeding: Levothyroxine is generally safe for use during pregnancy, but it's crucial to consult with your doctor. It can also pass into breast milk, so discuss it with your doctor before breastfeeding.
- Drug Interactions: Levothyroxine can interact with other medications, including those for epilepsy, depression, indigestion, high blood pressure, and heart problems. It's essential to inform your doctor about all medications, supplements, and herbal remedies you are using.
- Alcohol: Avoid alcohol consumption while taking levothyroxine, as it can interfere with the medication's effectiveness.
- Biotin: Biotin, a vitamin found in some supplements, can interfere with thyroid hormone tests. If you are taking biotin, inform your doctor or lab personnel before undergoing thyroid function tests.
