Aromasin® Tablets for Breast Cancer

Exemestane is an aromatase inhibitor used for hormone receptor–positive breast cancer. It lowers estrogen after menopause to support ongoing therapy. Border Free Health provides US shipping from Canada so you can review options, including Exemestane without insurance.

What Aromasin Is and How It Works

Border Free Health connects U.S. patients with licensed Canadian partner pharmacies; prescriptions are verified with prescribers before dispensing.

Aromasin® is the brand name for an aromatase inhibitor. Exemestane blocks the aromatase enzyme and reduces estrogen production. This action may help slow estrogen-driven tumor growth in postmenopausal patients. The treatment is used as adjuvant therapy after initial tamoxifen or for advanced disease when cancer has progressed after other endocrine options. It is taken by mouth and works systemically.

This medicine is steroidal and binds irreversibly to aromatase. By reducing circulating estrogen, it can support long-term endocrine management for hormone receptor–positive disease. Discuss goals and expected course with your healthcare professional, and rely on the official label for full instructions.

Who It’s For

This therapy is indicated for postmenopausal individuals with estrogen receptor–positive early breast cancer following tamoxifen, and for advanced or metastatic disease after progression on prior endocrine treatment. It is not intended for use during pregnancy or while breastfeeding. Premenopausal patients generally should not use it unless specifically directed by a specialist supervising ovarian suppression.

Those with severe liver or kidney impairment, significant osteoporosis, or a history of fractures should discuss risks, monitoring, and supportive measures. If you are exploring Exemestane online, review safety information and consult your prescriber before starting.

Some patients may transition from nonsteroidal aromatase inhibitors to this medicine or to other endocrine options such as Fulvestrant, depending on response and tolerance.

Dosage and Usage

For adults, the standard labeled schedule is one Exemestane 25 mg tablet once daily after a meal. Swallow whole with water. Taking it with food can improve absorption. Try to take it at the same time each day to maintain steady levels.

In the adjuvant setting, it may be used after 2 to 3 years of tamoxifen to complete a total of endocrine therapy as directed by your oncology team. For advanced or metastatic disease, it may be used after prior endocrine therapy has stopped working. Do not change your dose, start, or stop therapy without guidance. If uncertain, defer to the official prescribing information and your clinician’s plan.

Strengths and Forms

This medicine is supplied as film-coated Exemestane 25 mg tablets for oral use. Brand and generic presentations may vary by manufacturer and packaging. Some generics are produced by well-known companies such as Teva or other approved manufacturers in different regions. Availability can differ over time and by source.

Tablets are typically dispensed in child-resistant containers. The appearance and imprint may vary across manufacturers, but potency and active ingredient remain equivalent when approved as substitutable.

Missed Dose and Timing

If you miss a dose, take it when you remember unless it is close to the next scheduled dose. If it is near the next dose, skip the missed one and continue your regular schedule. Do not double up. Consistent daily timing after a meal can help with habit formation and steady exposure.

Storage and Travel Basics

Store tablets at room temperature in a dry place, away from excess heat and moisture. Keep the container tightly closed and out of reach of children and pets. Do not store in a bathroom. Protect tablets from light as advised on the label. Keep the pharmacy label intact for identification.

When traveling, carry your medicine in original packaging along with a copy of your prescription. Use a carry-on bag when flying to avoid extreme temperatures. If crossing borders, allow extra time for security checks and keep documentation handy. For online purchases, our site uses encrypted checkout for your protection.

Benefits

As part of endocrine therapy, this medicine helps reduce estrogen, which may slow growth of hormone receptor–positive breast cancer. It is an oral, once-daily option that can be used after tamoxifen in early disease or after other endocrine agents in advanced settings. Many patients appreciate the convenience of a tablet regimen under the supervision of their oncology team.

Side Effects and Safety

• Hot flashes and sweating
• Fatigue or low energy
• Nausea or upset stomach
• Joint or muscle pain
• Headache or dizziness
• Trouble sleeping

Less common but serious effects can include bone loss or fractures, elevated liver enzymes, depression, and severe allergic reactions. Cholesterol changes may occur. Report severe or persistent symptoms to a healthcare professional. Bone health monitoring and supportive measures such as vitamin D and calcium may be considered when appropriate.

Seek urgent care for signs of a severe reaction, including swelling of the face or throat, trouble breathing, or severe rash. Always read the Medication Guide and official label before use.

Drug Interactions and Cautions

Strong CYP3A4 inducers such as rifampin, carbamazepine, phenytoin, or St. John’s wort may reduce levels of the treatment and lower effectiveness. Estrogen-containing products, including hormone replacement therapy, can counteract its benefit and generally should be avoided during therapy. Discuss all medicines, vitamins, and supplements with your prescriber.

This medicine is not recommended during pregnancy or breastfeeding. Liver disease, kidney impairment, or a history of osteoporosis may require closer monitoring. Do not combine with tamoxifen unless your oncologist specifically instructs you to switch as part of an adjuvant plan.

What to Expect Over Time

Over time, reduced estrogen levels can help control hormone-driven cancer growth. Some effects, like hot flashes or joint aches, may appear early and can fluctuate. Your oncology team may monitor disease status with exams and imaging, and check bone health and labs as needed. Staying consistent with daily dosing and communicating side effects early can support adherence and allow timely adjustments to your overall care plan.

Compare With Alternatives

Nonsteroidal aromatase inhibitors, such as anastrozole or letrozole, are commonly used earlier in therapy. After progression or intolerance, clinicians may consider other endocrine strategies or targeted combinations. For HR-positive, HER2-negative metastatic disease with appropriate markers, CDK4/6 inhibitors like Kisqali or PI3K inhibitors like Piqray may be combined with endocrine therapy based on guidelines. The best option depends on stage, prior treatments, and tumor biology.

Patient Suitability and Cost-Saving Tips

This therapy suits many postmenopausal patients with hormone receptor–positive disease under oncology supervision. It may not be appropriate for those who are pregnant, breastfeeding, or premenopausal without ovarian suppression. Discuss bone health history and other risk factors with your care team.

For savings, consider multi-month fills when appropriate, which may reduce per-fill fees and cut repeated trips. Set refill reminders on your phone or calendar to avoid gaps in therapy. If you are looking for an Exemestane discount, compare generic versus brand options and ask your prescriber about clinically acceptable substitutions.
