Introduction

Letero 2.5mg is an anti-cancer drug that belongs to the class aromatase inhibitor. It is indicated as a supportive therapy after the main therapy or first-line therapy for postmenopausal women with early and advanced breast cancer whose tumors are hormone receptor-positive. Since high amounts of estrogen are found to trigger breast cancer, this medicine reduces the levels of the female reproductive hormone by blocking the enzyme (aromatase) that is involved in the production of estrogen. This medicine aims to slow or stop the growth and/or spreading to other body parts.

Inform your physician if you have not attained menopause yet, as this medicine does not work for premenopausal women. Since this medicine tends to reduce the levels of female reproductive hormones, it is not advised for menstruating women as it is related to causing fertility issues. It is advised to keep track of your cholesterol levels as this medicine tends to elevate cholesterol levels. This medicine could also decrease bone mineral density. Hence, discuss with your physician and consider monitoring your bone parameters regularly. It is advised to use effective birth control during the treatment and at least 3 weeks after the last dose because Letero 2.5mg can cause when it is administrated.
