Let's take a minute to talk about your medication. 

This is exemestane and you should take it as directed by your doctor. Take it at the same time each day, after a meal. 

Exemestane is not chemotherapy. It is hormone therapy. It causes your body to stop making estrogen. This can help slow or stop the growth of breast cancer that needs estrogen. In some patients, it can lower the chance that cancer will come back. 

Many patients tolerate it well. Some side effects can occur, though, like hot flashes, headache, feeling tired, or pain in your joints. Other common side effects are sweating, problems sleeping, or feeling anxious. These effects are normal if they are mild and should go away. It could also weaken your bones. Your doctor may order tests to make sure your bones stay strong. If these or other side effects become reasons you want to stop taking this medicine, please talk to your doctor or pharmacist. 

As with any medicine, rare but serious side effects can occur. A small number of women have had chest pain, heart failure, or a stroke. You should call your doctor right away if you notice unusual changes to your body, or if you just don't feel well. 

To reduce side effects, you should ask your doctor or pharmacist before taking any herbal remedies or other medicine, even if it doesn't require a prescription. 

You should also be certain you are past menopause, because this medicine is not safe for babies during pregnancy or breastfeeding. 

For best results, take exemestane exactly as prescribed and read the patient information leaflet for full information.
