Using this medicine while you are pregnant can harm your unborn baby. If you are a woman who can bear children, your doctor may give you a pregnancy test before you start using this medicine to make sure you are not pregnant. Women should use an effective form of birth control during treatment and for 1 month after the last dose. Men should use an effective form of birth control during treatment and for 1 month after the last dose to prevent pregnancy in a sexual partner.

This medicine may increase your risk of developing infections, including a serious brain infection called progressive multifocal leukoencephalopathy.

Ibrutinib can temporarily lower the number of white blood cells in your blood, increasing the chance of getting an infection. It can also lower the number of platelets, which are necessary for proper blood clotting. If this occurs, there are certain precautions you can take, especially when your blood count is low, to reduce the risk of infection or bleeding:

  • If you can, avoid people with infections. Check with your doctor immediately if you think you are getting an infection or if you get a fever or chills, cough or hoarseness, lower back or side pain, or painful or difficult urination.
  • Check with your doctor immediately if you notice any unusual bleeding or bruising, black, tarry stools, blood in the urine or stools, or pinpoint red spots on your skin.
  • Be careful when using a regular toothbrush, dental floss, or toothpick. Your medical doctor, dentist, or nurse may recommend other ways to clean your teeth and gums. Check with your medical doctor before having any dental work done.
  • Do not touch your eyes or the inside of your nose unless you have just washed your hands and have not touched anything else in the meantime.
  • Be careful not to cut yourself when you are using sharp objects such as a safety razor or fingernail or toenail cutters.
  • Avoid contact sports or other situations where bruising or injury could occur.

This medicine may cause a heart condition called atrial flutter or atrial fibrillation. Check with your doctor right away if you have a fast or irregular heartbeat, trouble breathing, lightheadedness, dizziness, or fainting.

Using this medicine may increase your risk of getting new cancers, including skin cancer. Talk to your doctor if you have concerns about this risk.

This medicine may cause a serious type of reaction called tumor lysis syndrome. Your doctor may give you a medicine to help prevent this.
