What is aromatase inhibitor drugs used for?

Aromatase helps the body make oestrogen, particularly after the menopause. Aromatase inhibitors reduce this production. Lower oestrogen can slow or stop the growth of breast cancer cells that use the hormone as a signal.

They are used when test results show that hormone-sensitive breast cancer may respond to hormone treatment. They may be prescribed after other treatment, for cancer that has spread, or to reduce the chance of cancer returning, depending on the clinical plan.

Take the tablet on the schedule provided and tell your team before stopping it. Mention joint or muscle pain, hot flushes, vaginal symptoms, mood changes, or sleep problems so these can be assessed. Your team may review bone health, cholesterol, and other factors during treatment.

Gentle movement and strength exercises may support mobility, but choose activities that match your health and treatment plan. Do not start supplements or hormone products without medical advice.

Contact your team promptly for sudden severe bone or joint pain, a new fall or suspected fracture, chest pain, sudden breathlessness, or one-sided leg swelling. Seek urgent help for sudden weakness, trouble speaking, or severe allergic swelling.

Ask why this drug was chosen, how long the plan may last, how symptoms will be managed, and whether bone-health checks are appropriate for you.
