If you or someone you know has been prescribed Exemestane, you probably have a list of questions buzzing in your head. Is it safe? How often should you take it? What side effects might show up? Below we break down the basics in plain language so you can feel confident about using this medication.
Exemestane belongs to a group called aromatase inhibitors. In simple terms, it blocks the enzyme aromatase that turns hormones called androgens into estrogen. Lower estrogen levels slow the growth of hormone‑sensitive breast cancers, especially after surgery or radiation. Think of it like turning down the volume on a speaker that’s feeding the cancer cells the fuel they need.
The drug is taken as a once‑daily tablet, usually 25 mg, and you can swallow it with or without food. Because it permanently binds to aromatase, the effect lasts until the body makes new enzymes – that’s why you don’t need multiple pills a day.
Start with the right dose. Most doctors start patients on 25 mg a day, but your doctor may adjust it based on blood tests and how you feel. Never change the dose yourself.
Take it at the same time each day. Consistency helps keep hormone levels steady and reduces the chance of missed doses.
Watch for side effects. Common ones include hot flashes, joint pain, fatigue, and mild nausea. If you notice severe joint swelling, sudden mood changes, or high fever, call your doctor right away.
Bone health matters. Lower estrogen can thin your bones over time. Ask your doctor about calcium, vitamin D, or a bone‑density scan to stay ahead of potential issues.
Stay hydrated and keep a food diary. Some people feel stomach upset after a big meal. Light, regular meals and plenty of water often ease that discomfort.
Check drug interactions. Over‑the‑counter pain relievers, certain antidepressants, and some herbal supplements can interfere with Exemestane. Always let your pharmacist know everything you’re taking.
Plan for regular check‑ups. Your oncologist will likely order blood work every few months to monitor hormone levels, liver function, and cholesterol. Those labs guide any needed adjustments.
Lastly, keep a simple notebook or phone note with the date you start each new pack. If you ever lose track, that quick record saves you from double‑dosing or missing a day.
Exemestane isn’t a cure‑all, but when paired with surgery, radiation, or other therapies, it can be a powerful tool against hormone‑driven breast cancer. By staying informed, following your doctor’s guidance, and listening to your body, you give yourself the best shot at a smooth treatment journey.
