What To Tell Your Doctor Before You Start

Before taking IBRANCE, it’s important to talk to your healthcare team about any health issues or other medications you’re taking, including prescription medicines, over-the-counter medicines, vitamins, and herbal supplements. IBRANCE and other medicines may affect each other and cause side effects.

Additionally, before you take IBRANCE, tell your healthcare provider if you:

  • have fever, chills, or any other signs or symptoms of infection
  • have liver or kidney problems
  • have any other medical conditions

Tell your healthcare provider if you are pregnant or plan to become pregnant; IBRANCE can harm your unborn baby. 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 and have 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.

Tell your healthcare provider if you are breastfeeding or plan to breastfeed; it is not known if IBRANCE passes into your breast milk. You and your healthcare provider should decide if you will take IBRANCE or breastfeed. You should not do both.

Tips For Taking IBRANCE

Monitoring Considerations

To monitor side effects, your healthcare team will perform a blood test to check your complete blood count before starting IBRANCE and at the beginning of each cycle (month). For the first 2 cycles, you'll need a complete blood cell count on day 15 as well. Make sure to tell your healthcare team which day you start your first and second cycles, so they can schedule your day 15 appointment at the right time.

A complete blood cell count is the only monitoring requirement for IBRANCE. Patients taking IBRANCE do not require EKG heart monitoring. Your healthcare team will determine if any additional monitoring is needed.

If your blood test results indicate low white blood cell counts (neutropenia), your healthcare team may temporarily hold or adjust your dose. It’s not uncommon to have doses modified throughout treatment. Be sure to follow your dosing schedule exactly as your healthcare team prescribes and talk to your doctor if you have any questions about monitoring.

Additional Side Effect Tips

Before you make any changes to your diet or exercise routine, consult with your healthcare team. Also note that these tips are not specific to lBRANCE and that if you do experience any side effects, share them with your healthcare team early so that they can help you manage them.

  • Infection
  • Nausea And Vomiting
  • Sore Mouth
  • Tiredness And Weakness


It’s important to take steps to protect yourself against infection throughout your treatment. In addition to your healthcare team’s instructions, these tips may help:

  • Tell your healthcare team right away if you have fever, chills, or any other signs or symptoms of infection
  • Wash your hands often
  • Avoid exposure to people who might be sick

Nausea And Vomiting

If you’re nauseated or vomiting, talk to your healthcare team for instructions on how to deal with symptoms. Additionally, these tips may help:

  • Try to eat 5 or 6 small meals a day instead of 3 large ones
  • Since dehydration may contribute to nausea, sip water throughout the day
  • Consider relaxation techniques, such as deep breathing

Sore Mouth

Check your mouth and tongue daily for sores, white spots, or infections, and inform your healthcare team about any changes right away. In addition to your healthcare team’s instructions, here are some tips:

  • Avoid tobacco, drinking alcohol, and spicy and acidic foods
  • Eat foods that are soft and easy to chew or swallow
  • If you have mouth pain, sucking on ice chips or Popsicles® may help

Tiredness And Weakness

The physical and mental toll of treatment can leave you feeling tired or weak. In addition to your healthcare team’s instructions, these tips may help:

  • Build a schedule to make sure you’re getting rest and activity
  • Take short naps or breaks
  • Try doing light exercise each day. But make sure you talk to your healthcare team before you make any changes
