LETROZOLE

LETROZOLE: Letrozole, also known by its brand name Femara, is a medication primarily used in the treatment of breast cancer in postmenopausal women. It is classified as an aromatase inhibitor, which means it works by reducing the amount of estrogen produced in the body.

In breast cancer treatment, estrogen can promote the growth of certain types of tumors. Letrozole works by blocking the enzyme aromatase, which converts androgens (male hormones) into estrogen. By inhibiting this enzyme, the drug lowers estrogen levels and helps slow down or stop the growth of estrogen-dependent breast cancer cells.

The standard dose of letrozole for breast cancer is 2.5 mg taken once daily. It can be taken with or without food. Letrozole is usually prescribed for a period of five years to provide long-term protection against the recurrence of breast cancer. It is important to follow the prescribed dosing schedule and not exceed the recommended dose.

Like any medication, letrozole may cause side effects. Common side effects include hot flashes, joint pain, fatigue, headache, nausea, and bone pain. Some women may also experience an increase in cholesterol levels while taking letrozole. Serious side effects are rare but can include allergic reactions, liver problems, and osteoporosis (brittle bones). It is important to inform your healthcare provider if you experience any unusual or severe side effects while taking letrozole.

As with any cancer treatment, it is crucial to discuss the potential benefits and risks of letrozole with your doctor to determine if it is the right medication for your specific case.
