Letrozole is a medication commonly used in the treatment of breast cancer. It belongs to a class of drugs known as aromatase inhibitors, which work by decreasing the amount of estrogen produced in the body. Letrozole is primarily used in postmenopausal women who have hormone receptor-positive breast cancer. Here are some key indications for the use of letrozole:
Letrozole works by inhibiting the enzyme aromatase, which is responsible for converting androgens into estrogen. By reducing estrogen levels in the body, letrozole can help slow or stop the growth of hormone receptor-positive breast cancer cells.
Common side effects of letrozole may include hot flashes, night sweats, fatigue, and joint pain. Serious side effects such as bone fractures and osteoporosis are also possible with long-term use of letrozole.
Letrozole is typically taken orally once a day, with or without food. It is important to follow your healthcare provider’s instructions on how to take letrozole and to not exceed the prescribed dosage.
In conclusion, letrozole is a valuable medication in the treatment of hormone receptor-positive breast cancer. It is essential to understand the indications for use, potential side effects, and proper dosing when taking letrozole as part of your treatment plan.
