Exemestane
About Exemestane
Exemestane is an oral prescription medication used to treat hormone-receptor-positive early and advanced breast cancer in women who have completed menopause. It is prescribed to help lower the risk of the cancer returning or spreading to other parts of the body. By targeting the hormones that some breast cancers need to grow, this medication plays a vital role in long-term cancer management.
This medication is typically taken once daily, and it is highly recommended to take it consistently at the same time each day to maintain steady levels in your body. You should take Exemestane with food, preferably after a meal, as this significantly improves how well your body absorbs the medicine. To support your overall health and bone strength during treatment, your doctor may suggest incorporating weight-bearing exercises and a calcium-rich diet into your daily routine.
Common side effects of this medication include hot flashes, joint pain, muscle stiffness, and feeling unusually tired. While these are often mild, you must consult your doctor immediately if you experience serious side effects, such as sudden chest pain, shortness of breath, or signs of liver damage like yellowing of your skin or eyes.
Before starting Exemestane, talk to your doctor if you have a history of osteoporosis, liver disease, or kidney problems. Do not take this medicine if you are pregnant, planning to become pregnant, or breastfeeding, as it can harm an unborn baby. This treatment is strictly intended for women who have already gone through menopause.
Some medications, including oestrogens, herbal supplements like St. John's wort, and certain anti-seizure drugs, can interact with Exemestane and reduce its effectiveness. It is also wise to discuss your alcohol consumption with your doctor, as regular drinking can worsen bone thinning. Always consult your healthcare provider if you belong to specific patient groups, such as elderly individuals with pre-existing bone conditions, to ensure safe monitoring.

Habit Forming
Diet & Lifestyle Advise
- Protect your bone health: Because Exemestane lowers oestrogen, it can weaken your bones. Ensure your diet includes plenty of calcium and vitamin D, found in dairy products, leafy greens, and fortified foods, or speak to your doctor about appropriate supplements.
- Engage in weight-bearing exercise: Regular physical activities such as walking, light jogging, or strength training help maintain bone density and support joint flexibility during your therapy.
- Eat a heart-healthy diet: Focus on a balanced diet rich in fiber, whole grains, and lean proteins while limiting saturated fats to help manage your cholesterol levels, which can sometimes fluctuate during hormone therapy.
- Manage hot flashes: Wear layers of breathable clothing, keep your living space cool, and limit spicy foods, caffeine, and alcohol, as these can trigger or worsen hot flashes.
Special Advise
- Your doctor may advise you to measure body density before, during, and after the treatment, as Exemestane may cause bone thinning due to the reduction of estrogen in the body.
- Exemestane should be taken under strict medical supervision. The doctor will regularly monitor your condition while taking Exemestane.
Patients Concern
Disease/Condition Glossary
Breast cancer is a type of cancer that develops in breast cells stimulated by a female sex hormone called estrogen. Breast cancer may form in lobules (glands that produce milk), ducts of the breast (the pathway that brings milk from glands to the nipple), fatty tissue, or fibrous connective tissue within the breast. The tumour cells invade other healthy breast cells and travel to lymph nodes, which are the primary pathways through which the cancer cells move to other parts of the body. Symptoms of breast cancer include a lump in the breast or tissue thickening which feels different than the normal surrounding tissues, breast pain, redness, swelling, nipple discharge other than breast milk, bloody discharge, unexplained change in shape, size or appearance of the breast, peeling, flaking or scaling of the skin, and a lump or swelling under the arm.

Yes, Exemestane commonly affects the hair by making it thin, which further causes loss of hair. However, it is not very common. Hair reduction possibly happens due to the estrogen-lowering effect of Exemestane. These effects are not long-lasting and may return after some time. If it matters to you, inform your doctor of another alternative medicine to avoid harm to your hair.
Exemestane causes dizziness and drowsiness. So, drive only if you are alert and omit driving or operating machinery if you feel dizzy or drowsy.

No, Exemestane is only designed for women who have fully gone through menopause. It is not effective in women whose ovaries are still actively producing oestrogen. Talk to your doctor to determine the right treatment for your menopausal status.
Taking this medication with food, especially after a meal, helps your digestive system absorb the active ingredients much better. This ensures that you get the full therapeutic benefit of each dose. Talk to your doctor or pharmacist if you struggle to take it with meals.
The duration of your treatment depends entirely on your specific cancer stage, history, and how well you tolerate the medication. Many patients take it for several years as part of a long-term care plan. Talk to your doctor about your personalised treatment timeline.
Yes, joint and muscle pain or stiffness are common side effects of this medication because of the reduction of oestrogen levels in your body. Regular gentle exercise, staying hydrated, or mild pain relievers can help manage this discomfort. Talk to your doctor if your joint pain becomes severe or interferes with your daily activities.
Yes, because this medicine lowers oestrogen levels, it can lead to a decrease in bone density, which may increase your risk of bone thinning or fractures over time. Your healthcare provider may monitor your bone health using specialised scans. Talk to your doctor about calcium and vitamin D supplements to help protect your bones.
There is no direct chemical interaction between alcohol and Exemestane, but moderate to heavy alcohol intake can accelerate bone loss and worsen hot flashes. It is generally best to limit your alcohol consumption during treatment. Talk to your doctor about safe alcohol limits for you.
