2.5 mg Letrozole Tablet
Letrozole is a non-steroidal hormone therapy belonging to the third-generation aromatase inhibitors. It is a targeted anti-tumor medicine used primarily to treat hormone receptor-positive breast cancer (both early-stage and advanced) in postmenopausal women. It works by reducing estrogen levels, thereby slowing or stopping the growth of estrogen-dependent tumors. In certain cases, it is also prescribed for ovulation induction in women with fertility disorders.
Key Indications
Breast Cancer Management (First or Post-Tamoxifen): Used as adjunct therapy before or after tamoxifen, following surgery with or without radiation therapy.
Ovulation Induction: Used off-label in women with infertility, especially those with Polycystic Ovary Syndrome (PCOS).
Recurrence Prevention: Helps reduce the risk of cancer relapse after initial treatment.
Guidelines for Use
Standard Dose: 2.5 mg once daily is the commonly prescribed dose.
Timing: Take at the same time each day to maintain consistent hormone suppression.
Administration: Swallow the tablet whole with water; it may be taken with or without food.
Duration: Treatment often continues for 5 years or longer, as advised by an oncologist.
Major Safety Checklist
Pregnancy Alert: Strictly contraindicated in pregnancy. Use only under medical supervision when prescribed for fertility.
Bone Health: Long-term use may reduce bone mineral density. Calcium supplements and DEXA scans may be recommended.
Cholesterol Monitoring: Regular checks are needed as it may increase cholesterol levels.
Caution with Activities: Avoid driving or operating machinery until you understand its effects (e.g., dizziness).

- Hot flashes or sweating
- Joint, bone, or muscle pain (arthralgia)
- Fatigue or muscle weakness
- Dizziness or headache

Note: Seek immediate medical attention if you experience chest pain, blurred vision, or severe leg swelling.
Frequently Asked Questions (FAQs)
Q: Is Letrozole a chemotherapy drug?
A: No. It is a hormonal therapy, not traditional chemotherapy. It works by blocking the aromatase enzyme, reducing estrogen production.
Q: Why is Letrozole used in fertility treatment?
A: It increases Follicle-Stimulating Hormone (FSH), helping stimulate ovulation, especially in women with PCOS.
Q: Can I drink alcohol while taking Letrozole?
A: Occasional alcohol is generally acceptable, but it may worsen side effects like hot flashes, dizziness, or fatigue.
Q: What should I do if I miss a dose?
A: Take it if remembered within a few hours. If it’s close to the next dose, skip it—do not double dose.
Q: Does Letrozole cause weight gain?
A: Some women may notice mild weight changes or fluid retention. A healthy diet and regular exercise can help manage this.
