What is levothyroxine and what is it used for?
Levothyroxine (L-thyroxine or synthetic T4) is a synthetic form of the thyroid hormone named thyroxine, and represents the first-line treatment for hypothyroidism.
When the thyroid gland —responsible for regulating body metabolism— decreases or halts the production of thyroxine, the medication compensates for this deficit and balances the patient's well-being, so that they feel as if they have no health problem at all.
Hypothyroidism can have natural causes, or arise after the removal of the gland through surgery, or due to injuries to it caused by other medications or radiation. In any of these cases levothyroxine acts with proven efficacy, also used against other less common thyroid diseases; or combined with surgery and radioactive iodine therapy in thyroid cancer treatments.

Synthroid, Levoxyl, Euthyrox
Levothyroxine in the United States is among the top five most prescribed medications, and is generally presented for oral consumption, in compressed capsules of different microgram strengths (mcg); although it also comes in an injectable version.
Among the most common brands of this medication you can find Levo-T, Levoxyl, Synthroid, Tirosint, and Unithroid, which market units of between 25 and 500 mcg. The Food and Drug Administration in the USA (FDA) also approves Novothyrox and Levolet.
According to various specialists, levothyroxine capsules or pills are usually formulated from the hormone combined with some additives or excipients, and each brand includes a different dose of the medication's active ingredient in the tablets.
It is also important to analyze generic levothyroxine drugs, since between these and a brand-name medication there are differences in terms of name, appearance, prices, and more. In other words: they seem the same, but they are not. Hence the importance of consulting with your healthcare provider before changing brands of these thyroid medications.
FDA considerations on levothyroxine and alternative drugs
To replace natural thyroxine, there are two types of medications: levothyroxine, of synthetic origin; and DTE or desiccated thyroid extract. The latter is created from desiccated pig thyroid glands.
Along those lines, there are thyroid treatments in the United States with drugs such as Armour Thyroid, NP Thyroid, Nature-Throid, and Natural Thyroid, among others. However, the Food and Drug Administration in the USA does not approve therapies based on DTE medications, due to finding effectiveness issues with them.
According to the FDA's own records, there have been cases where a single lot included pills with different hormone levels, which would cause additional harm to patients. This is why it defends drugs of synthetic origin. But so far, it has not approved any that contain DTE, as reflected on its website.
To grant its approval to a medication, the institution requires a rigorous evaluation of safety, quality, and efficacy.
Is levothyroxine covered by my health insurance?
Yes. Levothyroxine is included in most health insurance plans in the USA. However, it is possible that in some cases your plan may not cover you if you decide to abandon the generic drug in search of another treatment.
For example, Synthroid is one of the medications for hypothyroidism, classified as a higher-tier drug. Many health plans in the United States cover it, including the government's Medicare and Medicaid plans. But most insurance companies prefer to cover levothyroxine sodium, which is the generic version of Synthroid.
However, health insurance in the USA usually covers thyroid conditions as a pre-existing health condition. This would mean financial assistance for expenses related to tests to diagnose the disease, consultations with specialists, treatments, and surgeries. Details may vary depending on the plan and the insurance company.
In the case of Obamacare insurance, the coverage for this thyroid medication is quite similar to the one already described, and in most cases, the patient pays between $0 and $10 to obtain it.
How much does levothyroxine cost in the United States?
The price of levothyroxine in the United States and other thyroid medications is usually quite high. The figures vary depending on the type of medication, the strength, and the quantity to buy.
For example, a 90-day treatment of levothyroxine sodium, in 75 mcg oral tablets, can cost around 70 dollars. But if you are enrolled in Medicare, you could save between 20 and 60 dollars for that supply. Your total out-of-pocket expense will depend on the prescribed dose, your plan's coverage, whether it includes a copay, and if you have already met the deductible.
In the United States, there are also Patient Assistance Programs (PAPs), sponsored by pharmaceutical companies that offer discounts or free medications to people with low incomes, without health insurance, or with incomplete coverage. This is a way to reduce the costs of levothyroxine treatments in the USA.
