(trade name)


Therapeutic: antineoplastics
Pharmacologic: kinase inhibitors


Treatment of mantle cell lymphoma in patients who have not responded to at least one previous therapy.


Bind to and inactivates the BTK enzyme. Inhibits malignant B-cell proliferation.

Therapeutic effects

Decreased progression of mantle cell lymphoma.


Absorption: Well absorbed following oral administration.
Distribution: Unknown.
Protein Binding: 97.3%
Metabolism and Excretion: Mostly metabolized, primarily by the CYP3A enzyme system. One minor metabolite has antineoplastic activity. Metabolites are mostly eliminated in feces (80%), <10% excreted in urine.
Half-life: 4–6 hr.

Time/action profile (response)

PO1.9 mos†unknownunknown
†Median time to response.


Contraindicated in: Hepatic impairment;Concurrent use of strong CYP3A4 indcers/inhibitors; Obstetric: May cause fetal harm, pregnancy should be avoided; Lactation: Breast feeding should be avoided.
Use Cautiously in: Moderate inhibitors of CYP3A4 (↓ dose of ibrutinib may be necessary);Concurrent use of antiplatelet agents/anticoagulants (↑ risk of bleeding);Surgical procedures (if possible withhold for 3–7 days pre- and post-operatively;Patients with reproductive potential (effective contraception should be used).

  • bleeding (life-threatening)
  • neutropenia (most frequent)
  • thrombocytopenia (most frequent)
  • anemia

  • infections (life-threatening)
  • second malignancies


Drug-Drug interaction

Chronic concurrent use of strong CYP3A inhibitors including bocepravir, indinavir, ritonavir, nefazodone, nelfinavir, saquinavir, telaprevir significantly ↑ blood levels and should be avoided. If short term use of strong CYP3A inhibitors including clarithromycin, itraconazole, ketoconazole, posiconazole, telithromycin or voriconazole is necessary, ibrutinib may be temporarily interrupted. Moderate CYP3A inhibitors including amprenavir, aprepitant, atazanavir, crizotinib, darunavir, diltiazem, erythromycin, fluconazole, fosamprenavir, imatinib or verapamil ↑ blood levels and the risk of toxicity; if concurrent therapy is necessary, dose ↓ of ibrutinib and careful monitoring for toxicity is required. Strong CYP3A inducers including carbamazepine, phenytoin and rifampin significantly ↓ blood levels and effectiveness and should be avoided.Concurrent use of antiplatelet agents or anticoagulants ↑ risk of bleeding.Concurrent use of St. John's wort ↓ blood levels and effectiveness and should be avoided.Grapefruit juice or Seville oranges↑ blood levels and the risk of toxicity, avoid concurrent ingestion.


Oral (Adults) 500 mg once daily (four capsules); Concurrent use of moderate CP3A4 inhibitors—140 mg/day; dose modification required for various levels of toxicity.


Capsules: 140 mg

Nursing implications

Nursing assessment

  • Assess for signs and symptoms of infection (fever, chills) during therapy.
  • Monitor for signs and symptoms of bleeding (blood in stools or urine, prolonged or uncontrolled bleeding) during therapy.
  • Lab Test Considerations: Monitor CBC monthly; may cause neutropenia, thrombocytopenia, and anemia.
    • Monitor serum creatinine levels periodically during therapy; may cause renal failure.

Potential Nursing Diagnoses

Diarrhea (Side Effects)


  • Oral: Administer once daily with a glass of water at the same time each day. Swallow capsule whole; do not open, crush, or chew.
    • If therapy is interrupted for any adverse reactions, once symptoms have resolved to Grade 1 or baseline, reinitiate therapy at starting dose. If toxicity reoccurs, reduce dose by 1 capsule (140 mg/day); restart dose after first toxicity occurrence 560 mg/day; second occurrence at 420 mg/day, third occurrence at 280 mg/day, and if fourth toxicity occurs discontinue therapy.

Patient/Family Teaching

  • Instruct patient to take ibrutinib as directed, at the same time each day. Take missed doses as soon as remembered on same day and return to normal schedule; do not take extra capsules to make up for missed dose.
  • Caution patient to avoid grapefruit, grapefruit juice, and Seville oranges during therapy; may increase amount of ibrutinib in blood.
  • Advise patient to maintain adequate hydration during therapy to prevent renal failure.
  • Instruct patient to notify health care professional if signs and symptoms of infection or bleeding (blood in stools or black stools, pink or brown urine, unexpected bleeding or uncontrollable severe bleeding, vomiting blood or vomit that looks like coffee grounds, coughing up blood or blood clots, increased bruising, dizziness or weakness, confusion, change in speech, headache that last a long time) occur.
  • Inform patient of risk of other types of cancer including skin cancer.
  • Advise patient of common side effects: low blood platelet count, diarrhea, low white blood cell count, low red blood cell count, fatigue, muscle and bone pain, swelling legs and feet, upper respiratory tract infection, nausea, bruising, shortness of breath, constipation, rash, stomach pain, vomiting, decreased appetite. Instruct patient to notify health care professional if diarrhea is persistent.
  • Advise patient to notify health care professional of medication regimen before treatment or surgery.
  • Instruct patient to notify health care professional of all Rx or OTC medications, vitamins, or herbal products being taken and to consult health care professional before taking any other Rx, OTC, or herbal products.
  • Advise female patient to use contraception and avoid pregnancy and breastfeeding during therapy; may be harmful to fetus.

Evaluation/Desired Outcomes

  • Decrease in progression of mantle cell lymphoma.
