Drug-Drug interaction

Blood levels and risk of toxicity may be ↑ by CYP3A4 inhibitors including bocepravir, clarithromycin, conivaptan, indinvair, itraconazole, ketoconazole, lopinavir/ritonavir, nefazodone, nelfinavir, posaconazole, ritonavir, saquinavir, telaprevir, telithromycin, and voriconazole ; concurrent use should be avoided, but if necessary daily dose of ponatinib should not exceed 30 mg. Blood levels and effectiveness may be ↓ by CYP3A4 inducers including carbamazepine, phenytoin and rifampin ; avoid concurrent use if possible. Blood levels and effectiveness may be ↑ drugs that ↑ gastric pH including proton pump inhibitors, H2 blockers and antacids ; concurrent use should be avoided if possible.Levels and effectiveness may be ↓ by St. John's wort; concurrent use should be avoided.Levels and risk of toxicity may be ↑ by grapefruit juice; concurrent use should be avoided.

Nursing implications

Nursing assessment

  • Monitor for signs and symptoms of CHF (shortness of breath, chest pain, palpitations, dizziness, fainting). Treat symptomatically, consider discontinuation if serious.
  • Monitor blood pressure and heart rate periodically during therapy. May cause hypertension.
  • Assess for bleeding during therapy. Interrupt therapy if severe hemorrhage occurs.
  • Monitor for fluid retention. May require interruption, reduction of dose, or discontinuation of therapy.
  • Lab Test Considerations: Obtain CBC and platelet counts every 2 wk for first 3 mo, than monthly or as clinically indicated. If neutropenia (ANC <1 × 109/L) and thrombocytopenia (platelet <50 × 109/L) occur unrelated to leukemia, interrupt therapy and resume initial 45 mg dose after recovery to ANC <1.5 × 109/L and platelet <75 × 109/L. For second occurrence, interrupt therapy and resume at 30 mg dose after recovery to ANC <1.5 × 109/L and platelet <75 × 109/L. For third occurrence, interrupt therapy and resume at 15 mg dose after recovery to ANC <1.5 × 109/L and platelet <75 × 109/L.
    • Monitor AST, ALT, alkaline phosphatase, and bilirubin at baseline, at least monthly, or as clinically indicated. May require interruption, dose reduction, or discontinuation. If ↑ liver transaminase >3 × the upper limit of normal (Grade 2 or higher) with 45 mg dose, interrupt and monitor hepatic function. Resume at 30 mg dose after recovery ≤Grade 1 (<3 × upper limit of normal); With 30 mg dose, interrupt and resume at 15 mg dose after recovery ≤Grade 1. With 15 mg dose, discontinue ponatinib. If ↑ AST or ALT ≥3 × the upper limit of normal concurrent with ↑ bilirubin >2 × upper limit of normal and alkaline phosphatase <2 × upper limit of normal, discontinue ponatinib.
    • Monitor serum lipase every 2 wk during first 2 mo and then monthly and as clinically indicated. Monitor patients with a history of pancreatitis or alcohol abuse more closely. If asymptomatic Grade 1 or 2 ↑ of serum lipase occurs, consider interruption or dose reduction. If symptomatic Grade 3 or 4 ↑ of lipase (>2 × upper limit of normal) or asymptomatic radiologic pancreatitis (Grade 2 pancreatitis) occurs at 45 mg dose, interrupt therapy and resume at 30 mg after recovery to ≤Grade 1 (<1.5 × upper limit of normal). Occurs at 30 mg dose, interrupt therapy and resume at 15 mg after recovery to ≤Grade 1 (<1.5 × upper limit of normal). Occurs at 15 mg dose, discontinue ponatinib. If symptomatic Grade 3 pancreatitis occurs at 45 mg dose, interrupt therapy and resume at 30 mg after complete resolution of symptoms and recovery to ≤Grade 1. Occurs at 30 mg dose, interrupt therapy and resume at 15 mg after complete resolution of symptoms and recovery to ≤Grade 1. Occurs at 15 mg dose, discontinue ponatinib.
    • Monitor uric acid levels prior to therapy and treat high levels prior to therapy to minimize risk of tumor lysis syndrome.
    • May cause ↑ serum glucose, potassium, sodium, creatinine, calcium, and triglycerides. May ↓ serum phosphorous, calcium, sodium, glucose, potassium, and bicarbonate.

Potential Nursing Diagnoses

Risk for infection (Indications)


  • Interrupt ponatinib at least 1 wk prior to major surgery; may compromise wound healing.
  • Oral: Administer once daily without regard to food. Swallow tablet whole; do not crush, break, or chew.

Patient/Family Teaching

  • Instruct patient to take ponatinib as directed and not to change dose or stop taking unless advised by health care professional. Do not double doses to make up for missed dose.
  • Caution patient to notify health care professional immediately if symptoms suggestive of a blood clot (chest pain, shortness or breath, weakness on one side of the body, speech problems, leg pain, leg swelling), liver failure (yellowing of eyes or skin, tea-colored urine, drowsiness), congestive heart failure, pancreatitis (nausea, vomiting, abdominal pain or discomfort), unusual bleeding, easy bruising, fluid retention (leg swelling, abdominal swelling, weight gain, shortness of breath) or fever occurs.
  • Advise patient to notify health care professional if signs of slow heart rate (fainting, dizziness, chest pain) or signs of rapid heart rate (palpitations, dizziness) occur.
  • Instruct patient to maintain adequate hydration to minimize risk of tumor lysis syndrome.
  • Advise patient to notify health care provider of therapy prior to surgery or if had recent surgery.
  • Advise female patient that ponatinib is teratogenic. Advise patient to use effective contraception during therapy and to notify health care professional if pregnancy is planned or suspected or if breastfeeding.

Evaluation/Desired Outcomes

  • Decreased progression of leukemia.
