Breast Cancer Treatment

Letrozole is primarily used in the treatment of certain types of breast cancer. This is particularly beneficial for postmenopausal women who have hormone receptor-positive breast cancer.

• It is commonly prescribed after surgery to reduce the risk of the cancer returning.
• Letrozole is also utilized as a part of a continuous treatment plan, following other types of cancer treatments such as tamoxifen therapy.

Fertility Treatments

An off-label use of Letrozole is its role in fertility treatments.

• It is used to induce ovulation in women with polycystic ovary syndrome (PCOS) and unexplained infertility.
• Studies suggest that Letrozole might be more effective and have fewer side effects than traditional fertility drugs like clomiphene citrate.

For more information on fertility options, the Mayo Clinic provides an extensive resource.

How Letrozole Works

Letrozole functions by inhibiting aromatase, an enzyme involved in estrogen production.

• It lowers estrogen levels, which can slow or halt the growth of certain types of breast cancer.
• This mechanism is particularly effective in hormone receptor-positive breast cancers, where cancer cells rely on estrogen to grow.

For additional insights into Letrozole’s mechanism, consider research studies available at PubMed Central.

Potential Side Effects

While effective, Letrozole is associated with several potential side effects.

• Common side effects include hot flashes, night sweats, and joint pain.
• Patients may also experience fatigue, dizziness, and increased cholesterol levels.

It’s crucial to discuss any side effects with your healthcare provider to manage them effectively.

Consultation and Precautions

Consulting a medical professional before using Letrozole is advised.

• Make sure you discuss your medical history and any other medications you are taking.
• Letrozole is not recommended for women who are or may become pregnant.
