Care During Chemotherapy and Beyond
Imbruvica™ is the trade name for the generic drug ibrutinib. In some cases, health care professionals may use the generic name ibrutinib when referring to the trade name Imbruvica™..
Imbruvica™ is a targeted therapy. Imbruvica™ inhibits the function of Bruton's tyrosine kinase (BTK). (For more detail, see "How this drug works," below.)
What Imbruvica™ Is Used For:
- Mantle cell lymphoma (MCL) who have received at least one prior therapy.
- Chronic lymphocytic leukemia (CLL) who have received at least one prior therapy.
- Waldenstrom’s macroglobulinemia
Note: If a drug has been approved for one use, physicians may elect to use this same drug for other problems if they believe it may be helpful.
How Imbruvica™ Is Given:
- Imbruvica™ is a capsule, taken by mouth once daily. You may take 1-4 capsules at once depending on your prescribed dose.
- Take Imbruvica™ at approximately the same time each day.
- Take Imbruvica™ exactly as prescribed.
- Swallow Imbruvica™ capsules whole with at least 8 ounces of water. Do not crush, open, chew or dissolve capsules.
- Do not change your dose or stop Imbruvica™ unless your health care provider tells you to.
- If you miss a dose of Imbruvica™, it should be taken as soon as possible on the same day with return to the normal schedule the following day. Do not take extra capsules of Imbruvica™ to make up the next dose.
- Do not take more than 1 dose of Imbruvica™ at one time. Call your health care provider and go to the emergency room right away if you take too much.
- Store at room temperature (68° F to 77° F); keep medication in original bottle; protect from high humidity, moisture and light.
- Keep out of reach from children and pets.
- Safely throw away any Imbruvica™ that is out of date or unused (ask your provider for directions on how to discard the medication).
- The amount of Imbruvica™ that you will receive depends on many factors, including your general health or other health problems, and the type of cancer or condition you have. Your doctor will determine your exact Imbruvica™ dosage and schedule.
Important things to remember about the side effects of Imbruvica™:
- Most people will not experience all of the Imbruvica™ side effects listed.
- Imbruvica™ side effects are often predictable in terms of their onset, duration, and severity.
- Imbruvica™ side effects are almost always reversible and will go away after therapy is complete.
- Imbruvica™ side effects may be quite manageable. There are many options to minimize or prevent the side effects of Imbruvica™.
The following side effects are common (occurring in greater than 30%) for patients taking Imbruvica™:
These are less common side effects (occurring in 10-29%) for patients receiving Imbruvica™:
Not all side effects are listed above. Some that are rare (occurring in less than about 10 percent of patients) are not listed here. Always inform your health care provider if you experience any unusual symptoms.

- Do not drink grapefruit juice, eat grapefruit or eat Seville oranges (often used in marmalades) while you are taking Imbruvica™. These products may increase the amount of Imbruvica™ in your blood.
- Before starting Imbruvica™ treatment, make sure you tell your doctor about any other medications you are taking (including prescription, over-the-counter, vitamins, herbal remedies, etc.).
- While taking Imbruvica™, do not receive any kind of immunization or vaccination without your doctor’s approval.
- Limit your time in the sun. Imbruvica™ can make your skin sensitive to sunlight. A severe sunburn, rash or worsening acne can occur with too much exposure. Remember to use sunscreen and wear a hat and clothes that cover as much of your skin as possible while taking Imbruvica™.
- Inform your health care professional if you are pregnant or may be pregnant prior to starting this treatment. Pregnancy category D (may be hazardous to the fetus. Women who are pregnant or become pregnant must be advised of the potential hazard to the fetus.)
- For both men and women: Barrier methods of contraception, such as condoms, are recommended during therapy and for at least 2 weeks after treatment is complete. Discuss with your doctor when you may safely become pregnant or conceive a child after therapy.
- Do not breast feed while taking Imbruvica™.
- While taking Imbruvica™, drink at least two to three quarts of fluid every 24 hours, unless you are instructed otherwise.
- Wash your hands often and after taking each dose of Imbruvica™.
- You may be at risk of infection so try to avoid crowds or people with colds, and report fever or any other signs of infection immediately to your health care provider.
- To help treat/prevent mouth sores while taking Imbruvica™, use a soft toothbrush, and rinse three times a day with 1 teaspoon of baking soda mixed with 8 ounces of water.
- Use an electric razor and a soft toothbrush to minimize bleeding.
- Avoid contact sports or activities that could cause injury.
- To reduce nausea, take anti-nausea medications as prescribed by your doctor, and eat small, frequent meals while taking Imbruvica™.

Monitoring and Testing:
You will be checked regularly by your doctor while you are taking Imbruvica™ to monitor side effects and check your response to therapy. Periodic blood work will be obtained to monitor the function of your organs (such as your kidneys and liver) as well as other side effects.
How Imbruvica™ Works:
Imbruvica™ is not a chemotherapy drug but one of what are termed "targeted therapies." Targeted therapy is the result of years of research dedicated to understanding the differences between cancer cells and normal cells. To date, cancer treatment has focused primarily on killing rapidly dividing cells because one feature of cancer cells is that they divide rapidly. Unfortunately, some of our normal cells divide rapidly too, causing multiple side effects.
Targeted therapy is about identifying other features of cancer cells. Scientists look for specific differences in the cancer cells and the normal cells. This information is used to create a targeted therapy to attack the cancer cells without damaging the normal cells, thus leading to fewer side effects. Each type of targeted therapy works a little bit differently but all interfere with the ability of the cancer cell to grow, divide, repair and/or communicate with other cells.
Imbruvica™ inhibits the function of Bruton's tyrosine kinase (BTK). BTK is a key signaling molecule of the B-cell receptor signaling complex that plays an important role in the survival of malignant B cells. Imbruvica™ blocks signals that stimulate malignant B cells to grow and divide uncontrollably.
Research continues to identify which cancers may be best treated with targeted therapies and to identify additional targets for more types of cancer.
