Westhroid is a medication that is used for treating an underactive thyroid and other types of thyroid problems. It is considered a "natural" product because it is made from the thyroid glands of pigs. Westhroid tablets, which are available by prescription, are not FDA-approved, but appear to meet certain consistency and potency standards. Potential side effects include hair loss, insomnia, and heart palpitations.
Westhroid™ (
thyroid USP) is a prescription medication used most often to treat an underactive thyroid (hypothyroidism), although it can be used to treat various other thyroid problems as well. Because Westhroid is made from the thyroid glands of pigs, it is considered a "natural" thyroid product.
Westhroid is manufactured by Western Research Laboratories.
The thyroid gland makes two different thyroid hormones: triiodothyronine (T3) and thyroid USP (T4). Usually, the thyroid gland produces much more T4 than T3; however, T3 is much more active than T4. The body can convert the T4 hormone into T3 as necessary. If your thyroid does not make enough thyroid hormones, there are a few different ways to increase your levels.
Most people with an underactive thyroid are treated with synthetic T4, also known as
levothyroxine (
Levoxyl®,
Levothroid®,
Synthroid®, and others). However, some people prefer to be treated with natural thyroid products, such as Westhroid. Westhroid is made from pig thyroid glands, so it contains both T3 and T4.
