Serious Warnings and Precautions
- JAMP-Anastrozole should not be taken by premenopausal women.
You will be carefully monitored by a healthcare professional while taking JAMP-Anastrozole if you have:
- Liver and / or kidney problems;
- Osteoporosis (bone thinning) or risk factors for osteoporosis.
What is JAMP-Anastrozole used for?
JAMP-Anastrozole is used for the treatment of postmenopausal women with hormone receptor positive breast cancer in the following conditions:
- Adjuvant treatment for early breast cancer.
- Advanced breast cancer.
How does JAMP-Anastrozole work?
In hormone sensitive breast cancer, estrogens stimulate tumour growth. Following menopause, estrogens continue to be produced in small amounts in other body tissues such as the breasts, muscle and fat.
JAMP-Anastrozole belongs to a group of medicines called aromatase inhibitors. It blocks the action of aromatase, an enzyme needed in the production of estrogens. This may help reduce the growth of breast cancer and delay the breast cancer from recurring.
Adjuvant therapy: Adjuvant means "in addition to." In early breast cancer, this means that additional treatment is required after primary treatment. The reason for this is that after surgery, a small number of cancer cells may remain in the body.
Adjuvant therapy is given to prevent or delay these cells from multiplying and spreading. The purpose of adjuvant therapy with JAMP-Anastrozole is to help to delay the breast cancer from recurring.

To help avoid side effects and ensure proper use, talk to your healthcare professional before you take JAMP-Anastrozole. Talk about any health conditions or problems you may have, including if you:
- Have any disorder or disease which affects your heart, liver or kidneys.
- Have a disorder or a disease which affects bone density. JAMP-Anastrozole lowers the level of female hormones which may cause a loss of mineral content of bones. This might make the bones weaker and lead to a broken bone. You should talk to your healthcare professional about your osteoporosis risk before using JAMP-Anastrozole.

Driving and using machines: JAMP-Anastrozole is unlikely to affect your ability to drive a car or use machines. However, some patients may feel weak or sleepy. If this happens, avoid driving or using machinery.
Tell your healthcare professional about all the medicines you take, including any drugs, vitamins, minerals, natural supplements or alternative medicines.
