Letrozole is a medication primarily used in the treatment of hormone receptor-positive breast cancer in postmenopausal women. As an aromatase inhibitor, it works by decreasing estrogen levels in the body, which can help slow or reverse the growth of certain types of breast tumors that need estrogen to grow.

How Letrozole Works
Letrozole functions by inhibiting the aromatase enzyme, which is responsible for converting androgens into estrogens. Here are a few key points about its mechanism:
- Reduces estrogen production in fatty tissues and adrenal glands.
- Helps in suppressing estrogen-dependent cancer cell growth.
- Can be used effectively in both adjuvant therapy and metastatic settings.
Dosage and Administration
Understanding the dosage is crucial to harness the full potential of Letrozole:
- The standard dosage for breast cancer treatment is typically one tablet (2.5 mg) taken once daily.
- It is essential to follow your healthcare provider’s instructions regarding duration and dosage adjustments.
- Consistent intake at the same time each day improves medication efficacy.
Possible Side Effects
While Letrozole is generally well-tolerated, some patients may experience side effects, including:
- Hot flashes
- Joint pain
- Fatigue
- Bone density loss (increased risk of osteoporosis)
Always consult with a healthcare provider for personalized advice and any serious side effects experienced.
