Xtane (exemestane) 25 mg tablets

Xtane is a prescription aromatase inhibitor used in hormone-sensitive breast cancer care. This page summarizes what it does, how it is typically taken, and key safety points to review with a clinician. Ships from Canada to US, with cash-pay options for people without insurance through our cross-border referral model.

What Xtane Is and How It Works

This medicine contains exemestane, a type of endocrine therapy (hormone-blocking treatment). It works by lowering estrogen levels in the body. In many breast cancers, estrogen can help cancer cells grow, so reducing estrogen may help slow hormone-driven disease. Exemestane is sometimes described as an “aromatase inhibitor,” meaning it blocks aromatase (an enzyme that helps make estrogen), particularly important after menopause.

The treatment is typically used in estrogen receptor-positive (ER+) breast cancer settings. Some people switch to exemestane after taking tamoxifen, while others use it for more advanced disease when other hormone therapies stop working. Medication requests are routed to licensed Canadian partner pharmacies for dispensing.

Who It’s For

Exemestane is generally prescribed for postmenopausal adults with hormone receptor-positive breast cancer. Indications can include early breast cancer after a period of tamoxifen therapy, or advanced/metastatic breast cancer after prior endocrine treatment. Your prescriber determines whether it fits the overall plan, which may also include targeted therapies, surgery, radiation, or chemotherapy.

Why it matters: Menopausal status and tumor hormone receptors change which endocrine options are appropriate.

This medicine is not appropriate for everyone. It should not be used during pregnancy due to potential fetal harm, and it may not be suitable for people with a known hypersensitivity to the active ingredient or certain formulation components. If breast cancer information hubs are helpful for navigating terminology and treatment types, browse the Breast Cancer collection. For background on this drug class in cancer care, see Exemestane 25 Mg Tablets.

Dosage and Usage

Typical label dosing for exemestane in adults is 25 mg by mouth once daily, usually after a meal. Some regimens involve switching after a defined period on tamoxifen, while others use ongoing daily dosing for advanced disease. Tablets should be swallowed whole with water, and the schedule should be followed exactly as prescribed.

If Xtane is prescribed, consistency matters because hormone suppression is tied to regular daily dosing. Do not change dose timing, stop, or restart therapy without clinical guidance. If a dose is missed, the official label and the prescriber’s instructions should guide next steps rather than doubling up. For additional context on endocrine therapy and where exemestane fits, the guide Aromasin Hormone Therapy may be useful.

Strengths and Forms

Exemestane is commonly supplied as a 25 mg oral tablet. Partner-pharmacy availability can vary by manufacturer and packaging, and some supplies may be listed as bottles or blister packs. If a specific pack count is needed for a care plan, confirm it during the prescription review process.

Xtane is typically presented as 25 mg tablets for once-daily use. The table below summarizes what is usually seen for this medication class, without implying a guarantee of a specific presentation.

Storage and Travel Basics

Store exemestane tablets at controlled room temperature and keep the container tightly closed. Protect the medicine from excessive moisture and heat, and keep it out of reach of children and pets. Avoid storing tablets in bathrooms or places with frequent temperature swings.

Quick tip: Keep tablets in the original labeled container while traveling.

For travel, carry the medication in hand luggage when possible and keep a copy of the prescription or pharmacy label available. If you manage multiple prescriptions, it can help to keep a simple list of names and doses in the same bag. If you need to browse other prescription categories while coordinating refills across therapies, the Other Medicines Category is a general directory.

Side Effects and Safety

Like other aromatase inhibitors, exemestane can cause menopausal-type symptoms because estrogen levels are reduced. Commonly reported effects include hot flashes, sweating, fatigue, headache, insomnia, and joint or muscle aches. Some people also notice mood changes or mild stomach upset. Side effects may be more noticeable early in treatment and can sometimes be addressed with supportive care guided by a clinician.

Xtane may also affect bone health over time, which is an important safety consideration in long-term endocrine therapy. A clinician may recommend periodic assessment of bone density and vitamin D status, along with lifestyle measures that support skeletal health. For practical, patient-centered strategies often used alongside clinician advice, see Handle Exemestane Side Effects. Prescriptions are verified with prescribers before dispensing.

When to seek urgent evaluation

Serious reactions are less common but need prompt medical attention. Seek urgent care for symptoms of a severe allergic reaction (such as facial swelling, hives, or trouble breathing). Chest pain, shortness of breath, sudden weakness, or severe dizziness should be evaluated immediately. Signs of liver problems can include yellowing of the skin or eyes, dark urine, or persistent right-sided abdominal pain. Any unusual vaginal bleeding after menopause also deserves timely clinical review.

Drug Interactions and Cautions

Medication interactions can change how exemestane works or increase risk of side effects. Estrogen-containing therapies (including some hormone replacement products) can counteract aromatase inhibitor effects and are usually avoided unless a prescriber has a specific reason. Certain strong enzyme-inducing medicines may lower exemestane levels, which could reduce effectiveness; examples can include rifampin and some seizure medicines.

Herbal products can matter too. St. John’s wort is a well-known inducer that may reduce levels of some medicines. Always share a full list of prescriptions, over-the-counter products, and supplements with the prescribing clinician and pharmacist. For broader context on interaction considerations across aromatase inhibitors, the overview Anastrozole Uses And Side Effects provides a useful comparison point without replacing personalized guidance.

Compare With Alternatives

Several endocrine options may be considered in hormone receptor-positive breast cancer, depending on menopausal status, prior therapies, and treatment goals. Aromatase inhibitors include exemestane, anastrozole, and letrozole. Another approach is fulvestrant (a selective estrogen receptor degrader), which is given by injection and may be paired with targeted medicines in some settings.

Xtane is one brand presentation of exemestane, while other brands or generics may be offered depending on supply. For product-level references, see Aromasin and Anastrozole.

Pricing and Access

Overall cost can vary based on manufacturer, package size, and the dispensing pharmacy. Many people using this service are paying cash rather than billing insurance, which can help when coverage is limited or a plan excludes certain medicines. If a prescriber changes therapy or dosing, the prescription details must match the medication being dispensed.

Xtane access on this platform is handled through a cross-border process, and US shipping from Canada is part of the service model. If available at the time of request, Site Promotions may help reduce out-of-pocket costs, but availability can change and there are no guarantees.

Cash-pay pathways can support people without insurance, but a valid prescription is still required. Dispensing is arranged through licensed Canadian pharmacies after the prescription is confirmed and reviewed.
