Aromatase inhibitors are essential medications used primarily in the treatment of hormone receptor-positive breast cancer, particularly in postmenopausal women. They work by blocking the aromatase enzyme, which converts androgens into estrogens, ultimately lowering estrogen levels in the body.

Types of Aromatase Inhibitors
There are several types of aromatase inhibitors available, each with its own characteristics:
- Anastrozole (Arimidex) – A non-steroidal aromatase inhibitor.
- Letrozole (Femara) – Another non-steroidal option that is commonly prescribed.
- Exemestane (Aromasin) – A steroidal aromatase inhibitor that irreversibly inhibits the aromatase enzyme.
How to Take Aromatase Inhibitors
When prescribed aromatase inhibitors, it’s crucial to follow your healthcare provider’s instructions carefully. Here are some general guidelines on how to take them:
- Dosage: Follow the dosage recommended by your doctor. Do not adjust the dose without consulting them.

- With or Without Food: Some aromatase inhibitors can be taken with or without food; however, confirm with your pharmacist or doctor.
- Missed Dose: If you miss a dose, take it as soon as possible. If it’s close to your next scheduled dose, skip the missed dose and resume your regular schedule. Never double up on a dose.
- Regular Check-ups: Regular monitoring through blood tests may be necessary to check estrogen levels and liver function.

While aromatase inhibitors are generally well-tolerated, some individuals may experience side effects, including:
