Hypothyroid Medication Names:
Levothyroxine is used in adults and children to treat hypothyroidism (underactive thyroid – a condition where the thyroid gland does not produce enough thyroid hormone). One of the most common thyroid medications is T4 because it has a long life span. People with hypothyroidism can still convert T4 into T3, the usable form of the hormone. Thus, most people take a T4 medication like levothyroxine. Yet, this therapy isn’t for everyone, and some people do combination therapy with T3 or occasionally use T3 solo. The thyroid gland is a butterfly-shaped endocrine gland that is normally located in the lower front of the neck.
Hypothyroidism can have a primary cause or a secondary cause. A primary cause is a condition that directly impacts the thyroid and causes it to create low levels of thyroid hormones. The difference between hypothyroidism and hyperthyroidism is quantity. In hypothyroidism, the thyroid makes very little thyroid hormone.

If it’s high, the test is done again, along with a blood test for the thyroid hormone T-4. If the results show that TSH is high and T-4 is low, then the diagnosis is hypothyroidism. In some cases, the thyroid hormone T-3 may be measured as well.

Yet, having an underactive thyroid does not mean you cannot make T3 out of synthetic T4. Generally, generic medications are less expensive than brand medications and are favored by most insurance companies.

Levothyroxine’also called l-thyroxine and L-T4’is a synthetic form of the T4 (thyroxine) hormone. T4 is the storage hormone, which your body must convert into T3, the active hormone, for your cells to use. For example, some cases image source of thyroiditis (thyroid inflammation) are caused by reversible situations, such as a response to a medication, infection, or following pregnancy. In a medical setting, you are not likely to miss a dose of levothyroxine injection.
Part of the reason many providers do not prescribe it is because they do not have specialized training in using other medications besides T4 for hypothyroid care. Like T4, T3 medication serves to increase T3 levels in your bloodstream. However, T3 has a shorter lifespan than T4, meaning that you have high levels of T3 for a short period, and then your levels can fall rapidly. On the contrary, T4 levels are more steady, so people do not need to take this medication as often. When hypothyroidism in infants isn’t treated, even mild cases can lead to severe physical and mental development problems.
