The thyroid gland is a small, butterfly-shaped gland located near the neck. It produces hormones that regulate metabolism and the body's ability to make and store energy. It's also known by the brand names Levoxyl, Synthroid, Unithroid, and Levoxyl/Synthroid.
Levoxyl (levothyroxine sodium) is a synthetic form of the thyroid hormone thyroid-stimulating hormone (TSH), and it is approved for treatment of hypothyroidism, or a lack of thyroid hormone production. It is also used to treat some forms of hyperthyroidism, such as Hashimoto's thyroiditis.
There are three types of thyroid dysfunction:
Levothyroxine sodium is often prescribed to people with hypothyroidism who have not responded to conventional treatment or are taking other thyroid medications. It is also used to treat hyperthyroidism, or a form of thyroid cancer.
If you are considering starting levothyroxine sodium treatment, you may have heard of Synthroid, a brand name of Synthroid, that has been approved by the FDA for the treatment of hypothyroidism. Other brand names of levothyroxine sodium include Levoxyl, Unithroid, and Unithroid. It is available in different strengths and is used to treat various conditions, including:
It's important to talk to your healthcare provider before starting levothyroxine sodium treatment. They will determine whether you should be started on levothyroxine sodium and whether the dosage is appropriate. Your healthcare provider may also recommend an alternative treatment option, such as surgery or hormone replacement therapy.
When it comes to levothyroxine sodium, it's important to talk with your healthcare provider about your individual health conditions, especially if you're taking other thyroid medications or have other medical conditions.

The recommended starting dose is one 50 mcg tablet taken twice a day for a total of 10 to 12 hours, but it can be increased to four 50 mcg capsules or 25 mcg capsules for a total of 12 to 14 hours.
Levothyroxine Sodium is available in different strengths and is used to treat different types of thyroid conditions, including:
It's important to talk with your healthcare provider about your thyroid hormone levels when starting Levothyroxine Sodium (Levothyroxine Sodium). They will determine the best dosage and duration of treatment, and can help you decide on the right dose and how to take it.
Levothyroxine Sodium is also available in various forms, including tablets, capsules, and oral liquids. These forms of levothyroxine Sodium (levothyroxine sodium) can be prescribed as a treatment option to treat other conditions, such as:
Thyroid-deficiency (TD) affects approximately half of all pregnancies in the United States, affecting the birth of babies and children in the third trimester of pregnancy. Symptoms may include hypothyroidism, fatigue, weight gain, and a tendency to have weight gain. Thyroid-dependent disorders (T-DRD) are more common in adults. T-DRD may develop in both infants and children, including in patients with chronic autoimmune disease.
T-DRD typically runs in families, especially in older children or those with a history of autoimmune disease. The goal of treatment is to alleviate symptoms and reduce the risk of developing T-DRD in a child. Treatment of T-DRD usually involves levothyroxine (Synthroid®) in the form of levothyroxine sodium, liothyronine (Synthroid®), and/or levothyroxine (T3) in the form of a thyroid capsule.
The exact mechanism of action for levothyroxine is not fully understood. However, the effects on thyroid hormones are believed to be related to a decrease in circulating free thyroxine (FT4) levels. The decreased FT4 levels are thought to be a key factor in the development of T-DRD in older children.
Levothyroxine sodium, also called liothyronine, is available as a capsule containing the thyroid hormones thyroxine-binding globulin (TGA) and thyroxine-binding globulin (TBB) in a form of a tablet. The thyroid hormone TSH is responsible for the normal development and maintenance of thyroid hormone levels in the body.
Synthroid® is a brand name for the brand-name levothyroxine sodium, sold under the brand name Synthroid®, and the generic brand levothyroxine sodium.
Levothyroxine USP, also known as Synthroid, is used to help low thyroid hormone levels in the body. It can help with the following problems:
Hypothyroidism:It causes the thyroid gland to produce too much thyroid hormone, which can cause symptoms like tiredness, muscle weakness, tiredness and slow breathing.
Thyroid Disease:Levothyroxine can damage the thyroid gland and cause problems with the production of thyroid hormone.
Hyponeurosis:Sometimes, people with hypothyroidism have symptoms of thyroid disease, such as confusion, muscle weakness, tiredness, slow breathing, and memory problems.
Hormone Regulation problems:Levothyroxine can also cause problems with hormone levels in the body. This is because levothyroxine acts by binding to hormone receptors in the cells, preventing the cells from producing enough thyroid hormone.
Levothyroxine is normally taken orally, with or without meals, once or twice a day. It is available in 5mg strength taken orally: levothyroxine 10mg, 25mg, 50mg, and 100mg.
The dose of levothyroxine depends on the type of person, their health status, and their response to the treatment. In the case of levothyroxine 10mg strength, a person usually receives a dose of 20 mg of levothyroxine per day, and in the case of levothyroxine 25mg strength, a person usually receives a dose of 25 mg per day.
In the case of other hormones like thyroid stimulating hormone (TSH) and folliclestimulating hormone (Foll)
Levothyroxine 10mg strength should be taken orally twice a day. If a person is taking an alpha-blocker, a dose of levothyroxine is taken twice a day.
Levothyroxine is usually taken with or without food.
Do not crush, chew, or break the levothyroxine tablets.
For children, the dose may need to be changed to 10mg strength.
Levothyroxine may also be used in the case of congenital abnormalities of the thyroid gland. It is not recommended to take levothyroxine during pregnancy unless absolutely necessary.
For women of childbearing age, the dose of levothyroxine may need to be changed to 10mg strength.

This is why you should discuss your drugs with your doctor before taking Levothyroxine. Levothyroxine can interact with certain foods and medicines, so it is important to take this medicine with a large meal or at least 1 hour after a meal.
Levothyroxine can interact with iron preparations, such as iron supplements, and can reduce the absorption of levothyroxine in the body. Therefore, iron supplements should be taken at least 1 hour before or 2 hours after levothyroxine.
Synthroid, a thyroid hormone replacement therapy for the relief of hypothyroidism, is well-known for its role in managing symptoms of hypothyroidism. Initially, it was theorized that it was derived from levothyroxine through inhalation of a dust particles from cats and horses. More recent research suggests that it may also be derived from its anion exchange component, suggesting a possible role for this component in the treatment of patients with hypothyroidism.
Research in the 1990’s revealed that patients given levothyroxine for at least two months experienced an average of 2.6 more attacks of depression compared to patients given no treatment (uncontro-summary ofidespread). Specifically, levothyroxine was associated with an average of 2.3 more attacks of depression (anion exchange), an average of 79 fewer attacks per month (phosphate dehydrogenase inhibitor), and an average of 8 fewer fewer kilometers (anhydrous) per day (metabolic equivalent). Similar findings were reported for individuals given a twice daily levothyroxine regimen.
Levothyroxine was first introduced into the market in 1942 as an antiseptic and broad-spectrum antibiotic. Its critical for the diagnosis and treatment of hypothyroidism, and during the following decades, levothyroxine became a key treatment option in the treatment of various autoimmune disorders, including rheumatoid arthritis, ankylosing spondylitis, acute generalized exanthematous pustulosis, and juvenile rheumatoid arthritis. Its long half-life, around three years, made it well-suited for use in the management of patients with thyroid hormone receptor-positive osteoporosis, specifically in patients with bone pain and in patients with a compromised heart and/or circulation.
For pediatric patients (ages 2 to 17 years) who cannot find other forms of thyroid hormone replacement therapy, we discovered levothyroxine at a dosage of 2.5 or 5.0 mcg per day, respectively, under the supervision of a pediatric anesthesiologist. The anesthetic tricyclic antidepressants (TcEAs), such as procainamide and sotalol, were also found to be effective in decreasing levothyroxine levels, even in the presence of levothyroxine anion exchange. It’s now been shown in numerous clinical trials in patients with thyroid disorders in which levothyroxine is co-administered with Riociguat (Adempas) to decrease the propensity of levothyroxine to accumulate in the blood.
The development of levothyroxine at a 5.0 mcg dose has been considered an testament to the safety and effectiveness of this hormone for pediatric patients, particularly in the light of the reports of decreased levothyroxine serum levels and an increase in levothyroxine dosage in elderly patients with thyroid disorders.
Recent scientific literature indicates that levothyroxine may be an effective treatment for patients with hypothyroidism, with research published in peer-reviewed medical journals providing mixed results. For example, in 2018 demonstrated that patients given a 2.5- or 5-day regimen of Riociguat, or a twice-daily dose of it, significantly lowered the dosage of levothyroxine to 5.0 or 5.
