Overview

Arimidex is anastrozole, a non-steroidal aromatase inhibitor used to treat breast cancer after menopause.

How it works

It blocks the aromatase enzyme reversibly, lowering the conversion of testosterone into estradiol throughout the body.

Chemistry

From PubChem, the US National Library of Medicine’s chemistry database.

Anastrozole

Formula: C₁₇H₁₉N₅
Molecular weight: 293.4 g/mol
CAS: 120511-73-1
PubChem CID: 2187 ↗

Clinical reference

The breast-cancer label amount is 1 mg once a day. Doctors who prescribe it off-label to men use far smaller amounts, such as 0.25 to 0.5 mg once or twice a week, and only when estradiol is high on bloodwork.

Label and guideline amounts are shown for reference only. They are not a recommendation, and we never give cycle or performance amounts. Any use belongs under a doctor’s care, with bloodwork.

Combinations and interactions

Prescribed or used alongside

Off-label, it is sometimes prescribed next to testosterone therapy when bloodwork shows high estradiol with symptoms.

Drug interactions

Tamoxifen: reduces anastrozole levels; the two are not combined in breast cancer.
Estrogen-containing medicines: work against it.

Risks and bloodwork

Estradiol too low

Joint pain, low libido, low mood and bone loss.

Bone density

Long-term use thins bones.

Cholesterol

Hot flushes

Bloodwork doctors check

Estradiol (sensitive assay)

Not for

People under 18, anyone pregnant or breastfeeding, and anyone with liver disease, heart disease, uncontrolled blood pressure or a hormone-sensitive cancer, unless a doctor directs otherwise.

Canadian legal status

In Canada this is a prescription drug under the Food and Drugs Act. Using it under a doctor’s care, with bloodwork, is how it is meant to be used. This is general information, not legal advice.

FAQ

How long does anastrozole last?

About 40 to 50 hours.

Can estradiol go too low?

Yes, and low estradiol in men causes real symptoms; bloodwork guides use.

Arimidex or Aromasin?

Anastrozole is reversible and non-steroidal; exemestane binds permanently.

How fast will it arrive?

Orders ship from Vancouver by Canada Post Xpresspost. You get a tracking number within 72 hours of payment; delivery then takes 1 to 2 business days in BC, 3 to 4 in Ontario and 3 to 5 in Quebec.
