Pause the progression and embrace today

In a clinical trial, IBRANCE® (palbociclib) plus letrozole paused disease progression 2X as long as letrozole alone (median time to progression of 20.2 months for IBRANCE plus letrozole vs. 10.2 months for letrozole alone).

IBRANCE® (palbociclib) is a prescription medicine used to treat hormone receptor-positive (HR+), human epidermal growth factor receptor 2-negative (HER2-) breast cancer that has spread to other parts of the body (metastatic) in combination with letrozole as the first hormonal based therapy in women who have gone through menopause.

The effectiveness of IBRANCE plus letrozole is based on a study that measured progression-free survival. There is an ongoing study to find out how IBRANCE works in combination with letrozole over a longer period of time.

It is not known if IBRANCE is safe and effective in children.

Low white blood cell counts (neutropenia). Low white blood cell counts are very common when taking IBRANCE and may cause serious infections that can lead to death. Your healthcare provider should check your white blood cell counts before and during treatment.

If you develop low white blood cell counts during treatment with IBRANCE, your healthcare provider may stop your treatment, decrease your dose, or may tell you to wait to begin your treatment cycle. Tell your healthcare provider right away if you have signs and symptoms of low white blood cell counts or infections such as fever and chills.

    • Females who are able to become pregnant and who take IBRANCE should use effective birth control during treatment and for at least 3 weeks after stopping IBRANCE.
    • Males who are taking IBRANCE with female partners who can become pregnant should use effective birth control during treatment with IBRANCE and for 3 months after the final dose of IBRANCE.

These are not all of the possible side effects of IBRANCE. For more information, ask your healthcare provider. Tell your healthcare provider if you have any side effect that bothers you or does not go away.

Tell your healthcare provider about all of the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements. IBRANCE and other medicines may affect each other, causing side effects. Tell your healthcare provider if you start a new medicine.

Take IBRANCE exactly as your healthcare provider tells you.

Take IBRANCE capsules with food and swallow the capsules whole. Do not chew, crush, or open IBRANCE capsules before swallowing them.
