Femara (Letrozole)⁚ Understanding Uses, Side Effects, and More
**Femara**, also known by its generic name **letrozole**, is a prescription medication primarily used to treat certain types of breast cancer in postmenopausal women. It belongs to a class of drugs called aromatase inhibitors, which work by blocking the enzyme aromatase, responsible for converting androgens into estrogen. As estrogen can fuel the growth of some breast cancers, lowering its levels can help slow or stop the cancer’s progression.
