Anastrozole(arimidex) recipe



Anastrozole is used to treat breast cancer in women after menopause. Some breast cancers are made to grow faster by a natural hormone called estrogen. Anastrozole decreases the amount of estrogen the body makes and helps to slow or reverse the growth of these breast cancers.

How to use Anastrozole

Read the Patient Information Leaflet if available from your pharmacist before you start taking anastrozole and each time you get a refill. If you have any questions, ask your doctor or pharmacist.

Take this medication by mouth with or without food as directed by your doctor, usually once a day.

What Anastrozole Is Used For:

  • Anastrozole is used to treat breast cancer in postmenopausal women.

Note: If a drug has been approved for one use, physicians sometimes elect to use this same drug for other problems if they believe it might be helpful.

How Anastrozole Is Given:

  • Anastrozole is a pill, taken by mouth.
  • You should take anastrozole at about the same time each day.
  • You may take anastrozole with or without food.
  • If you miss a dose of anastrozole, take it as soon as you remember unless it is almost time for the next dose. Do not take a double dose to make up a missed dose.
  • You should not stop taking anastozole without discussing with your physician, even if you feel well.

The amount of anastrozole that you will receive depends on many factors, including your general health or other health problems, and the type of cancer or condition being treated. Your doctor will determine your dose and how long you will be taking anastrozole.
