Aromasin® Tablets for Postmenopausal Breast Cancer

What Aromasin Is and How It Works

Aromasin® is the brand name for exemestane, a steroidal aromatase inhibitor used in hormone receptor–positive breast cancer after menopause. It lowers estrogen by irreversibly blocking the aromatase enzyme, which may help slow disease growth in appropriate stages. This page explains how the medicine is used and how to request it with US delivery from Canada, including options if you need exemestane without insurance.

YouDrugstore is a licensed Canadian pharmacy in Manitoba. Pharmacists review prescriptions before dispensing.

Exemestane belongs to a class called aromatase inhibitors. It reduces circulating estrogen levels, which certain breast cancers rely on to grow. The treatment is commonly used as adjuvant therapy after tamoxifen, and for advanced disease after antiestrogen failure. Always follow your prescriber’s directions and the official label.

To learn more about therapy basics for this class, see our Breast Cancer overview and this practical Exemestane Tablet guide.

Who It’s For

This medicine is indicated for postmenopausal women with estrogen receptor–positive early breast cancer after completion of initial tamoxifen therapy, as well as for advanced or metastatic disease after progression on antiestrogen treatment. It may be used alone or with other agents as directed by your healthcare professional.

It is not intended for premenopausal women unless under specialist oversight with ovarian suppression. Do not use during pregnancy or breastfeeding. People with severe liver or kidney problems should discuss risks. Avoid if you have known hypersensitivity to any component.

Dosage and Usage

The usual adult dose is one tablet taken once daily after a meal. Swallow whole with water. Consistent timing can support adherence. Do not crush or split unless your prescriber advises. If your clinician changes your regimen, follow their guidance and the package insert.

For adjuvant use, therapy is typically started after a period on tamoxifen and may continue to complete the recommended endocrine course. For advanced disease, it is given after antiestrogen therapy no longer works. Your exact plan may differ based on history and tolerance. Review bone health, calcium, and vitamin D needs with your clinician as appropriate for the class.

Strengths and Forms

Exemestane is supplied as film-coated oral tablets in a commonly available 25 mg strength. Packaging and manufacturers vary. Availability depends on stock and approved sources.

Missed Dose and Timing

If you forget a dose, take it when remembered the same day. If it is close to your next scheduled time, skip the missed dose and resume your normal schedule. Do not double up. Keeping a daily alarm or pill organizer can help you stay consistent.

Storage and Travel Basics

Store tablets at room temperature in a dry place, away from moisture and direct light. Keep the bottle tightly closed and out of reach of children and pets. Do not store in the bathroom. Use the original container with the pharmacy label for identification.

For travel, pack enough tablets for your trip plus a few extra days in case of delays. Carry a copy of your prescription and your prescriber’s contact information. Place medicine in your hand luggage, especially on flights. If crossing borders, keep it in original packaging to avoid questions at security.

Benefits

As part of endocrine therapy, this treatment helps reduce estrogen levels that fuel certain breast cancers. It can be used after prior antiestrogen therapy and fits into long-term adjuvant plans. Once-daily dosing after a meal is straightforward for many patients. Tablets are portable, which can simplify adherence during work or travel.

Side Effects and Safety

• Hot flashes or sweating
• Joint or muscle pain
• Fatigue or weakness
• Nausea or upset stomach
• Headache or dizziness
• Trouble sleeping
• Swelling in hands or feet

More serious risks can include bone thinning or fractures, mood changes, liver test changes, or allergic reactions. Seek urgent care for signs of severe rash, breathing issues, facial swelling, or chest pain. Report persistent bone pain, unusual bleeding, yellowing skin or eyes, or severe depression. The class can reduce bone mineral density; your clinician may suggest monitoring and supportive measures.

Drug Interactions and Cautions

Strong CYP3A4 inducers (such as rifampin, carbamazepine, phenytoin, or St. John’s wort) may lower blood levels and reduce effectiveness. Using estrogen-containing therapies or some herbal estrogenic products can counteract this medicine’s purpose. Discuss all prescription medicines, nonprescription products, and supplements with your prescriber and pharmacist.

Tell your care team about any history of osteoporosis, vitamin D deficiency, liver or kidney disease, or high cholesterol. Limit alcohol if advised. Do not start, stop, or change any medicines without guidance from a healthcare professional.

What to Expect Over Time

Response with endocrine therapy is gradual. Many people continue treatment for months or years based on stage and goals. Your team may order regular exams and imaging, and may monitor bone health. Keep a log of symptoms and questions between visits. If you feel unwell or develop new symptoms, contact your clinician promptly for advice.

Adherence matters with daily hormone therapy. Pair your dose with a routine activity, like breakfast. A calendar, smartphone reminder, or pharmacy refill alert can help reduce missed doses.

Compare With Alternatives

Other aromatase inhibitors may be considered if tolerability or access is an issue. One option is Anastrozole, which your prescriber may use in similar settings for postmenopausal patients. In certain advanced cases, an endocrine backbone may be combined with targeted agents such as Ibrance, based on your oncologist’s plan and label guidance.

Availability and Substitutions

Supply can vary by manufacturer and lot. If a particular pack size is unavailable, your prescriber may suggest an equivalent product from a different approved source. You can order exemestane online when in stock and upload a valid prescription. If your clinician recommends a different therapy, your pharmacist can help coordinate alternatives based on the prescription.

Patient Suitability and Cost-Saving Tips

Good candidates are postmenopausal adults with hormone receptor–positive disease as outlined in the label, and those able to maintain consistent daily dosing. It may not suit people with active pregnancy, severe uncontrolled liver disease, or those unable to tolerate aromatase inhibition. Your clinician will weigh benefits and risks.

To reduce costs, consider multi-month fills if appropriate. Align refills with clinic visits to simplify monitoring. Discuss generics and manufacturer options. Some patients ask about exemestane Canadian pricing when budgeting for therapy. Check the product page for current listings, then set a reminder a week before your expected refill window.
