What is Letrozole 2.5 mg?
Letrozole 2.5 mg is a prescription medication primarily used to treat breast cancer and infertility. Manufactured by Cipla Limited, this medication is an aromatase inhibitor that helps reduce estrogen production in the body. It plays a crucial role in managing hormone-sensitive conditions by lowering estrogen levels, which can stimulate the growth of certain cancers or affect ovulation.
Widely prescribed in Canada and other countries, Letrozole 2.5 mg is favored for its effectiveness and reliability in clinical settings. Patients prescribed this medicine should understand its purpose, usage, and safety instructions to maximize benefits while minimizing risks.
Uses of Letrozole 2.5 mg
- Treatment of hormone receptor-positive breast cancer in postmenopausal women, as with anastrozole 1 mg
- Management of infertility by inducing ovulation in women with ovulatory dysfunction, sometimes followed by a trigger such as hCG 2000 IU
- Adjuvant therapy to prevent breast cancer recurrence, similar to tamoxifen 20 mg
- Enhancement of assisted reproductive technology outcomes such as intrauterine insemination (IUI)
- Off-label use under medical supervision for other hormone-related conditions
How Letrozole 2.5 mg Works
Letrozole belongs to the class of aromatase inhibitors for breast cancer. It works by blocking the aromatase enzyme, which converts androgens into estrogen in the body. By inhibiting this enzyme, Letrozole 2.5 mg effectively lowers estrogen levels, hindering the growth of estrogen-dependent breast cancer cells.
In infertility treatment, reduced estrogen triggers the release of hormones that stimulate ovulation, helping women who have difficulty conceiving naturally. This dual mechanism makes Letrozole a versatile option for both cancer treatment and fertility enhancement.
