Letrozole

Letrozole is a prescription medicine used as an aromatase inhibitor. It lowers estrogen levels in the body by blocking the enzyme that helps make estrogen.

It is commonly used for certain fertility treatment plans and other conditions where lowering estrogen is helpful. Follow your prescriber’s directions carefully, and do not use it during pregnancy. Discuss all medicines, medical conditions, and possible side effects with your healthcare provider before taking Letrozole.
