Formula Information

A small arrow pointing down

Levothyroxine Sodium is a synthetic form of thyroxine, a hormone produced by the thyroid gland. This hormone is crucial for maintaining the body's metabolism, energy production, and normal growth and development. When the thyroid gland does not produce enough thyroxine, a condition known as hypothyroidism occurs. Levothyroxine Sodium 10 mcg/ml Oral Liquid is specifically designed to treat hypothyroidism and other conditions where thyroid hormone supplementation is necessary, such as certain types of goiters and thyroid cancer, when the thyroid gland is underactive or has been partially or completely removed.

The oral liquid formulation of Levothyroxine Sodium provides a precise dosage that can be easily adjusted to meet the individual needs of patients. This is particularly beneficial for patients who require very low doses of the medication or whose doses need to be titrated with precision. The liquid form is also ideal for patients who have difficulty swallowing pills, such as the elderly or children, and for those with conditions that affect the digestive system and may interfere with the absorption of solid dosage forms.

It is important for patients and prescribers to understand that Levothyroxine Sodium must be taken consistently at the same time each day, preferably on an empty stomach, to maintain stable hormone levels. The effectiveness of the medication can be influenced by a wide range of factors, including other medications, dietary choices, and certain medical conditions. Regular monitoring of thyroid function tests is necessary to ensure the dose remains appropriate. Adjustments to the dosage should be made based on clinical evaluation and laboratory findings.

For patients and prescribers considering Levothyroxine Sodium 10 mcg/ml Oral Liquid, it is essential to be aware of potential side effects, which can include symptoms of hyperthyroidism such as palpitations, nervousness, and increased appetite, especially if the dose is too high. Conversely, if the dose is too low, symptoms of hypothyroidism may persist. It is also important to note that this medication is intended for long-term use, and discontinuation should only occur under medical supervision.

Bayview Pharmacy is committed to providing high-quality compounded medications tailored to the specific needs of our patients. Our team of knowledgeable compounding pharmacists is available to answer any questions and provide guidance on the use of Levothyroxine Sodium 10 mcg/ml Oral Liquid. If you have any questions or require further information, please do not hesitate to reach out to us.

Drug Interactions

A small arrow pointing down

Levothyroxine sodium is a synthetic form of the thyroid hormone thyroxine (T4) and is used to treat hypothyroidism, a condition where the thyroid gland does not produce enough thyroid hormone. It is essential for maintaining the body's metabolism, growth, and development. When prescribing levothyroxine sodium oral liquid, it is crucial to consider potential drug interactions that may affect its efficacy and the patient's overall treatment plan.

One significant interaction is with antacids, calcium carbonate, and iron supplements, which can bind to levothyroxine and reduce its absorption. To minimize this interaction, levothyroxine should be taken on an empty stomach, typically 30 to 60 minutes before breakfast, and these supplements should be taken at least 4 hours apart from the levothyroxine dose. Similarly, cholestyramine, colesevelam, and colestipol can decrease levothyroxine absorption, so a time gap is recommended.

Proton pump inhibitors (PPIs) and histamine H2 receptor antagonists may decrease stomach acid, potentially affecting levothyroxine absorption. Patients on these medications may require monitoring and possible dose adjustments. Additionally, certain foods such as soybean flour, cottonseed meal, walnuts, dietary fiber, and grapefruit juice may affect the absorption of levothyroxine and should not be consumed at the same time as the medication.

Medications that increase metabolism of levothyroxine, such as rifampin, carbamazepine, phenytoin, and barbiturates, may necessitate an increase in levothyroxine dosage. Conversely, drugs like amiodarone, lithium, and tyrosine kinase inhibitors can increase the risk of hypothyroidism and may require a decrease in levothyroxine dosage.

Levothyroxine can also affect blood sugar levels, which is particularly important for diabetic patients. Insulin or oral hypoglycemic drugs may need to be adjusted when starting or changing the dose of levothyroxine. Additionally, levothyroxine can enhance the effects of anticoagulants such as warfarin, increasing the risk of bleeding. Close monitoring of INR or prothrombin time is advised when initiating or changing levothyroxine therapy in patients taking anticoagulants.

It is also important to note that levothyroxine can reduce the effectiveness of digitalis glycosides, and heart function should be monitored when these medications are used concurrently. Beta-blockers may also influence the efficacy of levothyroxine and adjustments to therapy may be necessary.

Lastly, selective serotonin reuptake inhibitors (SSRIs), particularly sertraline, have been reported to increase levothyroxine requirements in some patients. Close monitoring of thyroid function tests is recommended when starting or adjusting SSRIs.

Due to the complexity of these interactions, it is essential for patients and prescribers to communicate openly about all medications, supplements, and dietary habits. Regular monitoring of thyroid function tests is necessary to ensure the appropriate levothyroxine dose is maintained. If you have any questions or concerns regarding levothyroxine interactions, please reach out to us at Bayview Pharmacy for personalized advice and support.

How Does it Work

A small arrow pointing down

Levothyroxine Sodium is a synthetic form of thyroxine, a hormone naturally produced by the thyroid gland. This hormone is crucial for regulating the body's energy and metabolism. When the thyroid gland does not produce enough thyroxine, a condition known as hypothyroidism occurs. Levothyroxine Sodium is used to replace or provide more of this hormone in the body, effectively treating the symptoms of hypothyroidism, which can include fatigue, weight gain, and cold intolerance.

The 10 mcg/ml oral liquid formulation of Levothyroxine Sodium is designed to provide a precise dosage of the medication in a form that is easy to ingest. This is particularly beneficial for patients who have difficulty swallowing pills, such as young children, the elderly, or those with esophageal disorders. The liquid form allows for flexible dosing, which is essential since the required dose of levothyroxine can vary significantly between individuals, based on factors such as age, weight, and the severity of thyroid dysfunction.

Upon administration, Levothyroxine Sodium is absorbed primarily in the small intestine. It then enters the bloodstream and is transported throughout the body, where it binds to thyroid hormone receptors in the cells. By binding to these receptors, it initiates the same biological effects as endogenous thyroxine, thus normalizing metabolic processes and energy utilization. The goal of therapy with levothyroxine is to restore normal levels of thyroid hormone and TSH (thyroid-stimulating hormone), thereby alleviating the clinical manifestations of hypothyroidism.

It is important for patients and prescribers to understand that the effectiveness of Levothyroxine Sodium therapy depends on consistent daily dosing and regular monitoring of thyroid function tests. Adjustments to the dose may be necessary based on these test results and clinical evaluation. Additionally, the absorption of levothyroxine can be affected by certain foods and medications, so it is crucial to take it on an empty stomach and to separate it from other medications by at least 4 hours.

For those interested in using this formulation or seeking more information about the compounding process, dosing, and administration of Levothyroxine Sodium 10 mcg/ml Oral Liquid, please reach out to us at Bayview Pharmacy. Our team of compounding pharmacists is ready to assist with any questions or concerns you may have regarding this medication and its use in treating thyroid-related conditions.

Other Uses

A small arrow pointing down

Levothyroxine Sodium 10 mcg/ml Oral Liquid formulation, primarily used as a hormone replacement therapy for patients with thyroid disorders such as hypothyroidism, can also serve other essential roles in clinical medicine. This formulation ensures precision dosing for individuals requiring minute adjustments to their thyroid hormone levels, which may include patients with subclinical hypothyroidism or those undergoing suppression therapy for thyroid cancer remission. The flexibility in dosing is particularly beneficial here as it can aid in titrating to the exact level needed for therapeutic efficacy.

In addition to its primary use in thyroid hormone replacement therapy, Levothyroxine Oral Liquid may be considered for off-label uses where precise dosing is essential and gut absorption needs to be maximized. For instance, it can be useful in managing certain cases of depression where hypothyroidism is a contributing factor, emphasizing the tight interplay between thyroid function and mental health. The liquid formulation is particularly advantageous for patients with malabsorption syndromes or those who have undergone bariatric surgery, where the efficacy of oral solid dosage forms might be unpredictable due to altered gastrointestinal anatomy or function.

Furthermore, the oral liquid formulation is of great value for patients who have allergies or sensitivities to the excipients commonly used in tablet or capsule formulations of levothyroxine. It allows these individuals to avoid such excipients that may lead to allergic reactions or gastrointestinal distress. Caution should be taken, however, as the liquid form may still contain additives and preservatives that could cause adverse reactions in sensitive individuals.

The convenience of a liquid formulation can improve adherence in patients, especially amongst pediatric and geriatric populations who often encounter dysphagia or have aversions to swallowing pills. The flexibility allows for the adjustment of dosages in such populations, where weight-based dosing is necessary, without the need for tablet splitting or crushing, thus maintaining medication integrity.

The use of Levothyroxine Sodium 10 mcg/ml Oral Liquid remains a specialized area of treatment and prescribers should monitor thyroid function tests closely to maintain optimal therapeutic levels. The specific and various applications of this formulation underscore the importance of personalizing medicine to patient needs. Furthermore, it exemplifies the role of compounding pharmacies in providing tailored healthcare solutions. Should you have any questions about this formulation, its uses, or specific concerns regarding individualized therapy with Levothyroxine Sodium Oral Liquid, please reach out to us at Bayview Pharmacy. We are committed to providing comprehensive support for both patients and prescribers in the usage of compounded medications.
