Letrozole is a highly specialized hormonal medication specifically engineered to manage estrogen-dependent conditions. It belongs to the class of drugs known as Aromatase Inhibitors (AIs). It works by binding to the enzyme "aromatase," which is responsible for converting androgens (hormones produced by the adrenal glands) into estrogens. By blocking this conversion, Letrozole significantly lowers the systemic levels of estrogen in the body. This is critical because certain types of breast cancer cells require estrogen to grow, and certain ovulation disorders are caused by an imbalance in the estrogen-feedback loop.

Letrozole is a foundational therapy for two primary medical paths:
Breast Cancer Treatment: Adjuvant treatment of postmenopausal women with hormone receptor-positive (ER+) early breast cancer, or advanced breast cancer that has spread.
Fertility (Ovulation Induction): Off-label use to stimulate the ovaries in women with Polycystic Ovary Syndrome (PCOS) or unexplained infertility. By lowering estrogen, it tricks the brain into producing more Follicle Stimulating Hormone (FSH).
Endometrial Thinning: Sometimes used before gynecological procedures to reduce the thickness of the uterine lining.
Pregnancy Risk: Letrozole must NOT be taken during pregnancy. It can cause severe birth defects or fetal death. Ensure a negative pregnancy test before starting. Bone Density: Long-term use for cancer treatment can lower bone mineral density, increasing the risk of Osteoporosis and fractures. Your doctor may prescribe Calcium and Vitamin D. Cholesterol: Letrozole may increase blood cholesterol levels; regular monitoring is advised. Driving: It may cause fatigue or dizziness. Do not drive until you know how the medication affects you. Premenopausal Status: For breast cancer, Letrozole is generally only effective in women who have fully reached menopause.
For maximum efficacy, Letrozole must be taken consistently at the same time each day to keep hormone levels stable.
Standard Dosage:
Breast Cancer: Typically one 2.5mg tablet once daily, often for 5 years or more.
Fertility Induction: Typically one 2.5mg tablet daily for 5 days, starting on Day 3 or 5 of the menstrual cycle (as directed by your specialist).
Application Tips:
With or Without Food: Letrozole can be taken regardless of meal times.
Swallow Whole: Do not crush or chew the tablet.
Missed Dose: Take it as soon as you remember. If it is almost time for your next dose, skip the missed one. Never take a double dose.
Consistency: For cancer patients, do not stop taking the medication without consulting your oncologist, even if you feel well.
Common side effects include "hot flashes," joint pain (arthralgia), night sweats, and fatigue. Some patients may experience thinning hair, nausea, or vaginal dryness. If you experience sudden chest pain, difficulty breathing, or swelling in one leg (signs of a blood clot), seek emergency medical care immediately.
Store in a cool, dry place below 30°C, protected from moisture and direct sunlight. Keep the tablets in their original blister packaging until the moment of use. Keep out of reach of children.
Q: How is Letrozole different from "Clomid"?
A: Both are used for fertility. However, Letrozole is often preferred for women with PCOS because it has a lower risk of multiple births (twins/triplets) and is often more effective at thinning the cervical mucus compared to Clomid.
Q: Will it cause "Weight Gain"?
A: Some women report mild weight changes due to the hormonal shift, but this varies. Maintaining a healthy diet and regular exercise can help manage this.
Q: Can I take "Ibuprofen" for the joint pain?
A: Usually, yes. Mild pain relievers are often used to manage the "achy" side effects of Aromatase Inhibitors. Consult our pharmacist to ensure it’s safe with your other medications.
Q: Is it "Chemotherapy"?
A: No. It is "Hormone Therapy" (Endocrine Therapy). It does not kill cells directly like chemo; instead, it starves hormone-sensitive cancer cells of the estrogen they need to survive.
