What should you know about Letroz letrozole?

Aromatase helps the body produce oestrogen, particularly after menopause. Letrozole inhibits this enzyme, reducing the hormone signal that can encourage some breast cancer cells to grow. The medicine is selected according to tumour biology and a person’s health; it is not appropriate for every cancer. Letrozole may be used after other treatment or as part of a longer treatment plan, depending on the clinical goal.

Because lower oestrogen can affect tissues throughout the body, people may notice hot flushes, sweating, sleep changes, vaginal dryness, fatigue or joint and muscle discomfort. Bone health is also part of the monitoring conversation.

Use the dose and timing on your prescription, and keep appointments for symptom review. Tell the team about bone problems, liver disease, high cholesterol, pregnancy possibility and all medicines or supplements. Gentle activity may help maintain strength, but choose an approach that suits your health. If side effects persist, your clinician can check for other causes, offer supportive measures or discuss a different endocrine plan. Do not alter the treatment on your own.

Report severe joint or bone pain, a fall with injury, persistent low mood, disabling fatigue or bleeding that is unexpected. Obtain urgent help for sudden chest pain, severe breathlessness, new weakness on one side, confusion or signs of a serious allergy such as facial swelling and trouble breathing. Keep taking the medicine as prescribed unless a clinician gives different instructions.

Is my cancer hormone-sensitive, and what is the goal of letrozole for me? What should I do if I miss a tablet? How will bone health and symptoms be monitored? Which medicines or supplements should I avoid?
