What Is Thyroid USP Used For?

Thyroid USP is used for treating various thyroid problems, including an underactive thyroid, goiters and thyroid nodules, and certain types of thyroid cancer. Although the medication has not been approved by the FDA, it is manufactured according to the formulation of the United States Pharmacopeia. Healthcare providers may also occasionally recommend off-label Thyroid USP uses, such as for treating depression (when used with antidepressants).

What Is Thyroid USP Used For? -- An Overview

Thyroid USP can also be used in the testing process for certain thyroid problems.
The "USP" part of the name stands for United States Pharmacopeia and signifies that the manufacturers of these products have prepared the medication according to the formulation or "recipe" of the United States Pharmacopeia (a non-governmental organization).

Why Is Thyroid USP Used for Hypothyroidism?

The thyroid is an important gland that produces hormones that help control metabolism and other functions of the body. It is located in the neck and is one of the largest glands in the human body. Hypothyroidism (an underactive thyroid) is a common disorder of the thyroid gland. It can occur as the result of two very different problems. It can occur due to problems that cause the thyroid to be underactive, such as inflammation of the thyroid, or it can be caused by medical treatments for other thyroid problems, such as an overactive thyroid (hyperthyroidism). Part of the thyroid is often intentionally destroyed using surgery or other treatments in an effort to treat hyperthyroidism, cancer, or nodules. However, sometimes too much of the thyroid is destroyed, leaving people with an underactive thyroid, which will need to be treated with thyroid hormone replacement, such as thyroid USP, for life.
Whatever the cause, the end result is the same -- the thyroid does not produce enough thyroid hormones, which results in the following hypothyroidism symptoms:
  • Hair loss and/or coarse, dry hair
  • Skin that is dry, rough, and pale
  • Constipation
  • A decreased sex drive
  • Weight gain
  • Fatigue and weakness
  • Feeling cold all the time
  • Muscle cramps
  • Changes in the menstrual cycle
  • Depression
  • Irritability
  • Memory loss.
As you can see, many of these symptoms can be subtle, and many people blame their symptoms on aging or stress, without realizing they have a thyroid problem. Because the symptoms are subtle and because hypothyroidism can be detected with a simple and inexpensive blood test, healthcare providers usually recommend that most adults be tested periodically.
Thyroid USP works to boost the body's thyroid hormone levels, which can work wonders for the symptoms of hypothyroidism. However, do not expect results overnight; it often takes several weeks to notice any improvement. Thyroid USP should never be used to increase energy or cause weight loss in people without a thyroid problem. It is important to understand that with this drug, more is not necessarily better. Taking too much or taking it without a medical need will cause symptoms of hyperthyroidism, some of which can be quite dangerous. This is why your healthcare provider will carefully monitor you using blood tests to make sure you are not taking too much or too little thyroid USP.
