Description
Letrozole 5 mg – Aromatase Inhibitor for Fertility & Breast Cancer Treatment
Letrozole 5 mg is an oral medication classified as a non-steroidal aromatase inhibitor. It is commonly used in two major areas of healthcare: hormone-sensitive breast cancer treatment in postmenopausal women and off-label fertility support in women with ovulatory dysfunction, such as PCOS.
Letrozole works by reducing estrogen levels in the body, thereby slowing or halting the growth of estrogen-dependent breast cancer cells and stimulating ovulation in women seeking pregnancy. It is a widely prescribed alternative to Clomiphene Citrate (Clomid) for women who have not responded to first-line fertility treatments.
Uses of Letrozole 5 mg
This medication is used for:
- Hormone receptor-positive breast cancer in postmenopausal women
- Ovulation induction in women with PCOS or other ovulatory disorders (off-label)
- Fertility treatment in assisted reproductive technologies (ART)
How Letrozole 5 mg Works
Letrozole inhibits the aromatase enzyme responsible for converting androgens into estrogen. This leads to a drop in estrogen levels, which is beneficial in two ways:
- In cancer treatment: Lower estrogen slows the growth of hormone-sensitive tumors.
- In fertility treatment: Reduced estrogen triggers a surge in follicle-stimulating hormone (FSH), helping induce ovulation.
Key Benefits:
- Highly effective for estrogen-positive breast cancer therapy
- Preferred option for ovulation induction in PCOS patients
- Can be used as part of IVF or IUI protocols
- Lower side-effect profile compared to Clomid in many women
Letrozole 5 mg Dosage & Administration
- For breast cancer: Usually taken once daily for several years
- For ovulation induction: Typically taken for 5 days early in the menstrual cycle (e.g., Day 3–7 or 5–9)
- Always follow your doctor’s exact dosage instructions
