How does anastrozole work?

Anastrozole belongs to a class of medications called non-steroidal aromatase inhibitors. It works by reducing the production of estrogen in the body. It does this by blocking the enzyme aromatase, which turns the hormone androgen into small amounts of estrogen in the body. Estrogen fuels the growth of hormone receptor-positive breast cancer, and by lowering estrogen levels, anastrozole helps to slow down or stop the growth of cancer cells.

Dosage of anastrozole

The dosage of anastrozole may vary depending on the specific condition being treated, individual patient factors, and the healthcare provider’s recommendations. It is important to follow the prescribed dosage instructions provided by the healthcare provider. If you forget to take your medicine, just skip the missed dose. Take your next dose at the normal time.

Directions for anastrozole use

Anastrozole should be taken exactly as directed by the healthcare provider. The medication is usually taken once daily, with or without food. It is important to swallow the tablet whole and not chew or crush it. Store at room temperature away from light and moisture. Do not store it in the bathroom.
