Exemestane: Uses, Benefits, Side Effects, and Dosage

What is Exemestane?

Exemestane is a prescription medication primarily used to treat hormone receptor-positive breast cancer in postmenopausal women. It belongs to a class of drugs known as aromatase inhibitors, which work by lowering estrogen levels in the body—helping to slow or reverse the growth of estrogen-dependent breast tumors.

It is commonly marketed under the brand name Aromasin.

How Does Exemestane Work?

Exemestane works by inhibiting the aromatase enzyme, which is responsible for converting androgens into estrogen in the body. By reducing estrogen levels, Exemestane deprives breast cancer cells of the hormone they need to grow and multiply.

Key Uses of Exemestane

• Adjuvant treatment of early-stage breast cancer after 2–3 years of tamoxifen therapy

• Treatment of advanced or metastatic breast cancer that has progressed following tamoxifen use

• Occasionally used off-label for reducing estrogen levels in other estrogen-sensitive conditions

Benefits of Exemestane

• Effective in lowering the risk of breast cancer recurrence

• Offers an alternative for patients who are resistant to tamoxifen

• Convenient once-daily oral dosage

• Generally well-tolerated with manageable side effects

Common Side Effects

While many patients tolerate Exemestane well, some may experience:

• Hot flashes

• Fatigue

• Joint or bone pain

• Nausea

• Headaches

• Increased sweating

Serious but rare side effects may include bone density loss (osteoporosis), liver problems, and cardiovascular issues. Always consult a healthcare provider if you notice unusual symptoms.

Dosage and Administration

• The typical dose is 25 mg once daily, taken after a meal.

• Always follow your doctor’s prescription and instructions.

• Do not skip doses, and take the medication at the same time each day for best results.

Precautions and Interactions

• Not suitable for premenopausal women

• Inform your doctor if you have liver or kidney issues

• May interact with certain medications like rifampin or St. John’s wort

Frequently Asked Questions (FAQs)

1. Can Exemestane be used for breast cancer prevention?
