It works by decreasing the amount of estrogen the body makes, which can slow or stop the growth of some breast tumors that need estrogen to grow.

What is Letrozole?

Letrozole is primarily used in postmenopausal women who have hormone-receptor-positive breast cancer. Its main functions include:

  1. Lowering estrogen levels in the body to hinder the growth of cancer cells.
  2. Being an alternative to tamoxifen for breast cancer treatment in specific cases.
  3. Being a potential fertility treatment option for women facing issues related to ovulation.

Indications for Use

The usage of Letrozole is indicated in the following scenarios:

  • Adjuvant treatment of hormone receptor-positive breast cancer in postmenopausal women.
  • To treat advanced breast cancer after tamoxifen therapy has failed.
  • In the context of fertility preservation, especially among women undergoing ovulation induction.

How to Use Letrozole

When prescribed Letrozole, it’s essential to follow your healthcare provider’s instructions. Generally, the dosage regimen includes:

  1. A daily oral intake, typically at a dose of 2.5 mg.
  2. Continuous use for a specified duration, often five years in the case of breast cancer treatment.
  3. Regular follow-ups to monitor effectiveness and any potential side effects.

Potential Side Effects

While Letrozole is effective, it’s also crucial to be aware of its potential side effects, which may include:

  • Hot flashes and sweating.
