Letclas Tablet for Breast Cancer in Postmenopausal Women
Introduction
Breast cancer is one of the most common cancers affecting women worldwide. Postmenopausal women, in particular, are at a higher risk of developing hormone receptor-positive breast cancer. Letclas Tablet, which contains Letrozole, is a medication widely used in the treatment of breast cancer in postmenopausal women. This article explores the benefits, mechanism of action, dosage, side effects, and precautions associated with Letclas Tablet.
What is Letclas Tablet?
Letclas Tablet is a prescription medication containing Letrozole, an aromatase inhibitor. It is primarily used to treat hormone receptor-positive breast cancer in postmenopausal women. The drug works by reducing estrogen levels in the body, which helps slow down or stop the growth of cancer cells.
How Does Letclas Tablet Work?
Breast cancer in postmenopausal women is often driven by the hormone estrogen. Even after menopause, a small amount of estrogen is produced in the body through the conversion of androgens by the enzyme aromatase. Letrozole, the active ingredient in Letclas, blocks aromatase, leading to a significant reduction in estrogen levels. This helps in slowing or stopping the growth of hormone-dependent cancer cells.
Uses of Letclas Tablet
Letclas Tablet is used for:
- Early-stage breast cancer – To reduce the risk of recurrence after initial treatment, such as surgery.
- Advanced or metastatic breast cancer – To slow the progression of cancer that has spread to other parts of the body.
- Fertility treatment (off-label use) – Sometimes used to induce ovulation in women with infertility issues.
Dosage and Administration
- Standard Dose: The usual recommended dose is 2.5 mg once daily.
- Duration: The treatment duration varies depending on the stage of cancer and the patient’s response. It may be continued for several years to prevent recurrence.
- With or Without Food: Letclas can be taken with or without food, preferably at the same time every day.
Side Effects of Letclas Tablet
Like all medications, Letclas may cause some side effects. Common side effects include:

Serious but rare side effects include:
- Severe allergic reactions (rash, swelling, difficulty breathing)

Precautions and Warnings
