LEVOTHYROXINE SODIUM
Overview
Levothyroxine Sodium is a medication primarily used to treat an underactive thyroid, a condition known as hypothyroidism. It works by replacing or providing more thyroid hormone, which is normally produced by the thyroid gland. Low thyroid hormone levels can occur naturally or when the thyroid gland is injured by radiation or medications, leading to various symptoms such as tiredness, weight gain, and depression. Levothyroxine Sodium helps to restore normal energy and metabolism levels, and improve growth, development, and mental function. It's important to note that this medication is not suitable for weight loss and misuse can lead to serious side effects.
Short Overview
Indications & Usage
Interactions with other Drugs
Levothyroxine Sodium can interact with various other medications, altering their effectiveness or increasing side effects. For instance, certain drugs like antacids, iron, and calcium supplements can reduce the absorption of Levothyroxine Sodium, making it less effective. Conversely, drugs such as antidepressants, blood thinners, and heart medications can increase the potency of Levothyroxine Sodium, potentially leading to an overdose.
Side Effects
Genetic Influences
Certain genes, such as DIO1, DIO2, CYP2D6, and UGT1A1, play a significant role in determining the effectiveness, dosage, and potential side effects of Levothyroxine Sodium. These genes influence how the body processes and eliminates the medication, thereby affecting how well it works and the amount needed. Genetic variations can also impact the rate of drug metabolism and the likelihood of experiencing side effects.
Genetic Influences
Levothyroxine Sodium, a medication used to treat thyroid hormone deficiency, can be influenced by certain genes in terms of its effectiveness, dosage, and potential side effects. These genes can affect how an individual's body processes the medication, which can in turn impact how well the medication works and how much is needed. Additionally, some genes may also influence the likelihood of experiencing side effects. Here are some key genes that play a role:
DIO1 and DIO2 genes: These genes are responsible for the conversion of thyroid hormone in the body. Variations can affect how well Levothyroxine Sodium works in treating thyroid hormone deficiency. Some people may need higher or lower doses based on these genetic differences.
CYP2D6 gene: This gene affects how the body metabolizes many drugs, including Levothyroxine Sodium. Variations can influence the rate at which the body processes the medication, potentially affecting the dosage required and the likelihood of side effects.
UGT1A1 gene: This gene is involved in the process of eliminating drugs from the body. Variations can affect how quickly Levothyroxine Sodium is removed from the body, which can impact the effectiveness of the medication and the dosage needed.
It is essential for healthcare providers to consider individual patient factors and understand their specefic genetic profiles to make personalized treatment decisions with LEVOTHYROXINE SODIUM

Indication & Usage
Levothyroxine Sodium is primarily used to treat conditions related to an underactive thyroid, a gland that plays a crucial role in our body's metabolism. This includes hypothyroidism, a condition where the thyroid does not produce enough hormones, leading to fatigue, weight gain, and depression. It is also used in the treatment of goiter, an abnormal enlargement of the thyroid gland, which can be caused by hormone imbalances, radiation therapy, or cancer. Additionally, it can be used to manage thyroid cancer, as maintaining the right level of thyroid hormones may slow the growth of cancer cells. Lastly, it is used in a thyroid hormone test, which helps doctors understand how well your thyroid is working.
Usage of LEVOTHYROXINE SODIUM
Levothyroxine Sodium is primarily used in the treatment of conditions where the thyroid gland does not produce enough hormones, a condition often referred to as hypothyroidism. It works by replacing or providing more thyroid hormone, which is normally produced by the thyroid gland. This hormone is essential for maintaining normal mental and physical activity. In children, it is crucial for normal mental and physical development. The medication is also used to prevent certain types of enlarged thyroid glands and to manage thyroid cancer.
When not to use LEVOTHYROXINE SODIUM
Levothyroxine Sodium should be used with caution in individuals who have heart conditions, such as coronary artery disease, as it can increase heart rate and blood pressure. It's also not recommended for those with untreated adrenal gland problems, as it can cause severe health complications. If a person has a thyroid disorder called thyrotoxicosis, where the body produces too much thyroid hormone, this medication should be avoided. Additionally, those with certain types of thyroid cancer may need to use a lower dosage. Lastly, if a person is allergic to any component of Levothyroxine Sodium, it should not be used.
Storage of LEVOTHYROXINE SODIUM
Levothyroxine Sodium should be stored in a cool, dry place, away from direct sunlight and heat. It is crucial to keep it at room temperature, ideally between 15 and 30 degrees Celsius. For transportation, it should be kept in a secure, airtight container to prevent exposure to moisture or damage. It is also important to avoid freezing the medication during transport. Always ensure the medication is out of reach of children and pets to prevent accidental ingestion.
Side Effects
Levothyroxine Sodium, a medication used to treat thyroid hormone deficiency, can have several side effects. While many people taking this medication do not experience serious side effects, it's important to be aware of potential reactions. These side effects can range from mild to severe, and may occur at any time during treatment. It's crucial to consult a healthcare professional if any of these side effects persist or worsen. Here are some of the most common side effects associated with Levothyroxine Sodium:
Weight changes: Either loss or gain can occur as the body adjusts to the medication. This is due to the influence of the drug on the body's metabolism.
Hair loss: May occur during the first few months of treatment. This effect is usually temporary as the body adjusts to the medication.
Increased heart rate: Some individuals may experience this. This can lead to feelings of a racing heart or palpitations, especially during the initial stages of treatment.
Nervousness or irritability: Can occur, often due to the body's reaction to increased levels of thyroid hormone.
Sweating: May occur as the body adjusts to the medication. This is due to the drug's influence on the body's temperature regulation.
Historical Perspective
Levothyroxine Sodium has a rich history that dates back to the late 19th century. In 1891, George Redmayne Murray, an English physician, first introduced the concept of thyroid hormone replacement. He treated a patient suffering from hypothyroidism by injecting sheep thyroid extract. This marked the beginning of thyroid hormone replacement therapy. However, it wasn't until the mid-20th century that Levothyroxine Sodium, a synthetic form of the thyroid hormone, was developed. In 1958, the U.S. Food and Drug Administration approved Levothyroxine Sodium for medical use. Since then, it has become a standard treatment for hypothyroidism, a condition where the thyroid gland does not produce enough thyroid hormones. Over the years, the manufacturing process and quality control of Levothyroxine Sodium have significantly improved, ensuring its safety and efficacy. Today, it remains one of the most prescribed medications worldwide.
