What is femara?

Femara is a prescription medication used to treat breast cancer in postmenopausal women. Its active ingredient is letrozole, which belongs to a class of drugs called aromatase inhibitors. Femara works by reducing the levels of estrogen in the body, which can slow or stop the growth of cancer cells that rely on estrogen to grow.

Femara is typically taken once a day in tablet form, with or without food. It is usually prescribed for a period of five years, but the length of treatment may depend on the individual's response to the medication and the progression of their cancer.

Common side effects of Femara include joint pain, hot flashes, fatigue, nausea, and bone fractures. More serious side effects, although rare, can include liver problems and an increased risk of osteoporosis.

Before taking Femara, patients should inform their doctor if they have a history of liver disease or osteoporosis, as well as any other medications they are taking. Pregnant women should not take Femara, as it can cause harm to the developing fetus.
