If you’re taking exemexane for breast cancer, you might wonder whether it raises your chance of a blood clot. The short answer: it can, but the risk is low for most people. Knowing the signs, how to lower the odds, and when to call a doctor can keep you safe while staying on your treatment.
Exemestane is an aromatase inhibitor, which means it lowers estrogen levels in the body. Estrogen helps keep blood vessels flexible and prevents clotting. When estrogen drops, the blood can become a bit stickier, especially if you already have risk factors like smoking, obesity, or a history of clots. Most studies show the increase in clot risk is modest, but it’s real enough to watch for.
Blood clots can show up in different places. A deep vein thrombosis (DVT) in the leg often feels like a painful, swollen, or warm area that doesn’t go away. A pulmonary embolism (PE) – a clot that travels to the lungs – can cause sudden shortness of breath, chest pain that worsens with breathing, or coughing up blood. If you notice any of these symptoms, don’t wait: seek medical help right away.
Other red flags include unexplained bruising, a sudden headache or vision changes (which could point to a clot in the brain), or pain in the arms or shoulders that seems out of proportion. Keep a checklist handy so you can quickly decide if something needs urgent attention.
While you’re on exemestane, regular check‑ups with your oncologist are key. They’ll monitor blood work, look for any clot‑related changes, and may adjust your dose if needed.
Staying active is one of the simplest moves you can make. Even short walks, ankle pumps, or leg stretches while sitting can keep blood flowing. If you travel long distances, stand up and move every hour or wear compression socks.
Maintain a healthy weight and stay hydrated. Drinking enough water helps keep blood thin, while excess weight puts more pressure on veins. If you smoke, quitting is a must – smoking dramatically raises clot risk, especially when estrogen is low.
Talk to your doctor about aspirin or other low‑dose blood thinners. Some patients on aromatase inhibitors benefit from a daily aspirin, but it’s not right for everyone. Your doctor will weigh benefits against bleeding risks.
If you develop any of the symptoms above, or if you notice new leg swelling, unusual fatigue, or unexplained bruising, call your healthcare team immediately. Even if you’re not sure, a quick check can rule out serious issues.
Also, let your doctor know about any other medicines you’re taking. Some drugs, like hormonal patches, certain chemotherapy agents, or even over‑the‑counter supplements, can add to clot risk.
Finally, keep a list of your risk factors handy – age, family history of clotting disorders, recent surgeries, or prolonged immobility. Sharing this information helps your doctor tailor prevention strategies just for you.
Exemestane is a powerful tool against hormone‑receptor‑positive breast cancer, and most people use it without major problems. By staying alert, moving regularly, and keeping an open line with your medical team, you can enjoy the benefits of the drug while keeping clot risks under control.
