Synthroid Levothyroxine Sodium: Side Effects, Uses, Dosage, Interactions, Warnings

The SYNTHROID dosage is based on the target level of TSH suppression for the stage and clinical status of thyroid cancer. It’s very important to remind the patients, in addition to these factors, that they need to check their pills on a consistent basis. Look to see if the tablets have Synthroid embossed on them to ensure they’re getting the right product. This is a key issue for some of the elemental things like calcium and iron, that can interfere with thyroid hormone absorption and thus should be taken approximately 4 hours apart.

Consider the potential for food or drug interactions and adjust the administration or dosage of SYNTHROID as needed see Dosage and Administration (2.1), Drug Interactions (7.1), and Clinical synthroid platelets Pharmacology (12.3). Titrate the dose of SYNTHROID carefully and monitor response to titration to avoid these effects see DOSAGE AND ADMINISTRATION. Consider the potential for food or drug interactions and adjust the administration or dosage of SYNTHROID as needed see DOSAGE AND ADMINISTRATION, DRUG INTERACTIONS and CLINICAL PHARMACOLOGY.

The choice between the two may depend on factors such as cost, availability, and individual patient preferences. It is recommended to consult with a healthcare provider for personalized advice and guidance regarding the use of these medications. As a generic medication, it is typically less expensive than the brand-name alternative, making it a more accessible option for patients. Despite being more affordable, Lannett Levothyroxine contains the same active ingredient and is expected to have the same therapeutic effects as Synthroid. Overall, the choice between Lannett Levothyroxine and Synthroid will depend on the individual patient’s preferences, budget, and experiences with the medications.

The higher affinity of both TBG and TBPA for T4 partially explains the higher serum levels, slower metabolic clearance, and longer half-life of T4 compared to T3. Protein-bound thyroid hormones exist in reverse equilibrium with small amounts of free hormone. Many drugs and physiologic conditions affect the binding of thyroid hormones to serum proteins see DRUG INTERACTIONS. Thyroid hormones do not readily cross the placental barrier see Use In Specific Populations. Because of the increased prevalence of cardiovascular disease among the elderly, initiate SYNTHROID at less than the full replacement dose see DOSAGE AND ADMINISTRATION and WARNINGS AND PRECAUTIONS.

What Drugs, Substances, or Supplements Interact with Synthroid?

It helped me understand the different pricing options available and gave me the tools to find the best deals. I would highly recommend reading the article for anyone who wants to save money and get the most value out of their purchases. In terms of side effects, Lannett Levothyroxine and Synthroid have a similar profile, with common side effects including headache, nervousness, irritability, increased appetite, and sweating. However, individual experiences may vary, and some individuals may tolerate one medication better than the other. Biotin supplementation is known tointerfere with thyroid hormone immunoassays that are based on a biotin and streptavidin interaction, which may result in erroneous thyroid hormone test results.

Important Considerations For Dosing

Long-term carcinogenicity studies in animals to evaluate the carcinogenic potential of levothyroxine have not been performed. Studies to evaluate mutagenic potential and animal fertility have not been performed. Closely monitor infants during the first 2 weeks of SYNTHROID therapy for cardiac overload and arrhythmias. Seizures have been reported rarely with the institution of levothyroxine therapy.

Specific Patient Populations

The major pathway of thyroid hormone metabolism is through sequential deiodination. Approximately 80% of circulating T3 is derived from peripheral T4 by monodeiodination. The liver is the major site of degradation for both T4 and T3, with T4 deiodination also occurring at a number of additional sites, including the kidney and other tissues. Approximately 80% of the daily dose of T4 is deiodinated to yield equal amounts of T3 and reverse T3 (rT3).

TSH may not normalize in some patients due to in utero hypothyroidism causing a resetting of pituitary-thyroid feedback. Assess compliance, dose of medication administered, and method of administration prior to increasing the dose of SYNTHROID see Warnings and Precautions (5.1) and Use in Specific Populations (8.4). Assess compliance, dose of medication administered, and method of administration prior to increasing the dose of SYNTHROID see WARNINGS AND PRECAUTIONS and Use In Specific Populations.

Adequate levothyroxine treatment during lactation may normalize milk production in hypothyroid lactating mothers with low milk supply. Concurrent use of sympathomimetics and SYNTHROID may increase the effects of sympathomimetics or thyroid hormone. Thyroid hormones may increase the risk of coronary insufficiency when sympathomimetic agents are administered to patients with coronary artery disease. Hypersensitivity reactions to inactive ingredients have occurred in patients treated with thyroid hormone products. These include urticaria, pruritus, skin rash, flushing, angioedema, various gastrointestinal symptoms (abdominal pain, nausea, vomiting and diarrhea), fever, arthralgia, serum sickness, and wheezing.
