1. what ibrance is and what it is used for

IBRANCE is an anticancer medicine containing the active substance palbociclib.

Palbociclib works by blocking proteins called cyclin-dependent kinase 4 and 6, which regulate cell growth and division. Blocking these proteins can slow down growth of cancer cells and delay the progression of your cancer.

IBRANCE is used to treat patients with certain types of breast cancer (hormone receptor-positive, human epidermal growth factor receptor 2-negative) which have spread beyond the original tumour and/or to other organs. It is given together with aromatase inhibitors or fulvestrant, which are used as hormonal anticancer therapies.

2. what you need to know before you take ibrance- if you are allergic to palbociclib or any of the other ingredients of this medicine (listed in section 6).

  • – use of preparations containing St. John’s Wort, a herbal product used to treat mild depression and anxiety, should be avoided while you are taking IBRANCE.
