Levoxyl is used for treating several conditions, such as underactive thyroid, goiters, and certain types of thyroid cancer. This prescription medication is a synthetic version of a naturally occurring thyroid hormone (levothyroxine, or T4) and works by boosting the body's thyroid hormone levels. Off-label Levoxyl uses include treating depression in conjunction with other antidepressant medications.
Levoxyl® (levothyroxine sodium) is a medicine that is a manufactured version of levothyroxine, a thyroid hormone. It is available only with a prescription and is used to treat the following conditions:
- Goiters (including thyroid nodules)
- Underactive thyroid (known medically as hypothyroidism)
- Certain types of thyroid cancer (when used with surgery or other treatments).
Levoxyl Uses for Hypothyroidism
An underactive thyroid (hypothyroidism) 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 become underactive (such as an inflammation of the thyroid), or it can be caused by 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 cancer, nodules, or hyperthyroidism. However, it is common to destroy too much of the thyroid, leaving people with an underactive thyroid.
Either way, the end result is the same -- the thyroid does not produce enough thyroid hormones, which results in the following hypothyroidism symptoms:
- Coarse, dry hair
- Skin that is dry, rough, and pale
- Fatigue and weakness
- Feeling cold all the time
- Weight gain
- A decreased sex drive
- Muscle cramps
- Hair loss
- Changes in the menstrual cycle
- 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. Levoxyl 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.
Levoxyl should never be used to increase energy or cause weight loss in people without a thyroid problem.
It is important to understand that with Levoxyl, more is not necessarily better. Taking too much 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 Levoxyl.
