How It Works
Mechanism of action
Non-steroidal aromatase inhibitor. Blocks the enzyme that converts testosterone to estradiol, lowering systemic estrogen. Some prescribers use low doses alongside testosterone therapy; use is prescriber-directed.
What compounding can change
When Anastrozole is compounded for one patient, your prescriber can choose the concentration, combine it with other ingredients, and pick the base. Commercial products come in fixed strengths and bases.

Please note: Compounded medications require a prescription from a licensed prescriber for an individual patient. Compounded medications are not FDA-approved. The FDA does not review them for safety, effectiveness or quality. A compounded medication is not the same as, or a generic version of, any FDA-approved drug. This page is general information, not medical advice. Your prescriber decides whether a treatment is right for you and sets the final ingredients, strength and dosage form.
