How Letrozole works.
Letrozole is an aromatase inhibitor, which means it works by blocking the production of estrogen in the body. Estrogen is a hormone that plays a crucial role in the growth and development of breast cancer cells. By reducing the amount of estrogen in the body, letrozole can slow or stop the growth of cancer cells.
Letrozole works by binding to the aromatase enzyme, which is responsible for converting androgens (male hormones) into estrogen. By blocking this enzyme, letrozole prevents the production of estrogen in the body. This can be particularly effective in postmenopausal women, as their bodies produce less estrogen naturally.
While letrozole is primarily used in the treatment of breast cancer, it may also be used in the treatment of infertility, as it can stimulate ovulation in women who are not ovulating on their own.
Uses of Letrozole.
As mentioned, letrozole is primarily used in the treatment of breast cancer. It is often used in postmenopausal women who have hormone receptor-positive breast cancer, which means their cancer cells are fueled by estrogen. By reducing the amount of estrogen in the body, letrozole can slow or stop the growth of cancer cells.
In addition to its use in breast cancer treatment, letrozole may also be used in the treatment of infertility. It can stimulate ovulation in women who are not ovulating on their own, which can increase their chances of getting pregnant.
Dosage and administration.
The recommended dosage of letrozole depends on the condition being treated. In the treatment of breast cancer, the typical dosage is 2.5mg once a day. In the treatment of infertility, the dosage may be higher or lower, depending on the individual's response to the medication.
Letrozole is taken orally, usually once a day. It can be taken with or without food, but should be taken at the same time each day to maintain consistent levels in the body.
Side effects of Letrozole.
Like all medications, letrozole can cause side effects. The most common side effects include:
Hot flashes.
Headaches.
Fatigue.
Joint pain.
Nausea.
Vomiting.
In some cases, letrozole can also cause more serious side effects, such as:
Blood clots.
Increased risk of osteoporosis.
Increased risk of endometrial cancer.
Liver problems.
If you experience any of these more serious side effects, it is important to contact your doctor right away.
Precautions and contraindications.
Letrozole should not be taken by women who are pregnant or breastfeeding, as it can harm the developing fetus or infant. It should also be used with caution in women with liver or kidney problems, as these conditions can affect the way the medication is metabolized in the body.
In addition, letrozole should not be taken by women with a history of blood clots or stroke, as it can increase the risk of these conditions.

Letrozole and breast cancer treatment.
