The paper looks at the medication levothyroxine used to treat hypothyroidism, a condition when patients manifest low levels of thyroid hormone due to insufficient regulation by the thyroid gland. The paper describes common symptoms of hypothyroidism and explains how the thyroid gland functions and why and when levothyroxine is used. The paper also looks at the dose, contraindications, side effects, adverse effects and drug interactions with levothyroxine and examines what a nurse treating patients for this condition needs to be aware of. The paper highlights the importance of effective patient self-care due to the fact that levothyroxine's effectiveness can be counteracted by a number of different foods, medicines and supplements.

From the Paper:

"To fully understand why and when levothyroxine is used, it is essential to understand how the thyroid gland functions. The thyroid has often been called the 'furnace' of the body. The gland is found in front of the neck near the trachea. The gland secretes three hormones: thyroxine (T4), triodothyronine (T3), and calcitonin. "T4 and T3 are known collectively as thyroid hormone....the hypothalamus releases thyroid-releasing hormone (TRH), which signals the pituitary to release thyroid-stimulating hormone (TSH), which in turn signals the thyroid gland to produce and release more thyroid hormone. Once hormone levels are sufficient, the hypothalamus cuts off the release of TRH, signaling the pituitary to stop releasing TSH" (Holcomb 2007).
"When the body is working properly, much like an efficiently functioning furnace, the thyroid naturally signals to the body to "produce and release more hormones. When the furnace is too hot (meaning the thyroid is secreting too much thyroid hormone), TSH production and secretion slow in an attempt to turn down the furnace, or slow the release of thyroid hormone. As you would expect, too much TSH (value higher than normal) means the patient has hypothyroidism; too little TSH (value lower than normal) means the patient has hyperthyroidism" (Holcomb 2007). Hypothyroidism is almost always treated with medication. Levothyroxine is a synthetic version of T4 used to replace the missing thyroid hormone."
