Drug-Drug interactionAdditive bone marrow depression may occur with other antineoplastics or radiation therapy.
Intravenous (Adults) Hairy cell leukemia–0.09 mg/kg/day for 7 days.
Availability (generic available)
Injection: 1 mg/mL
- Monitor for bone marrow depression. Assess for fever, chills, sore throat, and signs of infection. Monitor platelet count throughout therapy. Assess for bleeding (bleeding gums, bruising, petechiae; test stool, urine, and emesis for blood). Avoid administering IM injections and taking rectal temperatures. Apply pressure to venipuncture site for 10 min. Anemia may occur. Monitor for increased fatigue and dyspnea.
- Monitor IV site for phlebitis.
- Monitor intake and output. Development of uric acid nephropathy in patients with leukemia and lymphoma may be prevented with adequate oral hydration and allopurinol, if needed.
- Lab Test Considerations: Monitor CD4 T-lymphocyte count and CD8 T-lymphocyte count before initiation of therapy and periodically during and after therapy. Cladribine causes prolonged depression of CD4 and CD8 lymphocyte subset counts, with recovery taking at least 6–12 mo.
- Monitor hemoglobin, hematocrit, leukocyte, and platelet counts before and periodically throughout therapy, especially during the first 4–8 wk after treatment. During the first 2 wk after therapy, platelet counts, absolute neutrophil count (ANC), and hemoglobin decrease. Transfusions of platelets and red blood cells may be required. Platelet count, ANC, and hemoglobin usually return to normal levels by day 12, week 5, and week 8, respectively.
- Monitor renal and hepatic function before and periodically during therapy. May cause nephrotoxicity, resulting in elevated serum creatinine, anuria, and acidosis.
May cause irreversible neurologic toxicity, resulting in motor weakness progressing to paraparesis or quadriparesis with high doses. If symptoms occur, discontinue cladribine. There is no known antidote.
- Monitor serum uric acid concentrations before and periodically during therapy, especially in patients with high tumor burden. May cause elevated serum and uric acid concentrations. May require alkalinization of the urine.
Potential Nursing DiagnosesRisk for infection (Indications)
Risk for injury (Adverse Reactions)
- high alert: Fatalities have occurred with chemotherapeutic agents. Before administering, clarify all ambiguous orders; double-check single, daily, and course-of-therapy dose limits; have second practitioner independently double-check original order, calculations, and infusion pump settings.
- Prepare solution in a biologic cabinet. Wear gloves, gown, and mask while handling IV medication. Discard IV equipment in specially designated containers (see ).
- pH: 5.5–8.0.
- Continuous Infusion: Diluent: Add the daily dose to 500 mL of 0.9% NaCl for injection. Solution is stable for 24 hr at room temperature or 8 days if refrigerated.
- May also be prepared as a 7-day solution with bacteriostatic 0.9% NaCl for infusion via Pharmacia Deltec medication cassettes.
- Rate: Administer as a continuous infusion over 24 hr.
- Y-Site Compatibility: aminophylline, bumetanide, buprenorphine, butorphanol, calcium gluconate, carboplatin, chlorpromazine, cisplatin, cyclophosphamide, cytarabine, dexamethasone, diphenhydramine, dobutamine, dopamine, doxorubicin hydrochloride, droperidol, enalaprilat, etoposide, famotidine, furosemide, granisetron, haloperidol, heparin, hydrocortisone, hydromorphone, idarubicin, leucovorin, lorazepam, mannitol, meperidine, mesna, methylprednisolone, metoclopramide, mitoxantrone, morphine, nalbuphine, ondansetron, paclitaxel, potassium chloride, prochlorperazine, promethazine, ranitidine, sodium bicarbonate, teniposide, vincristine
- Additive Incompatiblity: D5W. Do not admix with other medications or solutions.
- Instruct patient to notify health care professional promptly in the event of fever; sore throat; signs of infection; bleeding gums; bruising; petechiae; blood in urine, stool, or emesis; unusual swelling; joint pain; shortness of breath; or confusion. Caution patient to avoid crowds and persons with known infections. Instruct patient to use soft toothbrush and electric razor and to be especially careful to avoid falls. Patients should also be cautioned not to drink alcoholic beverages or to take products containing aspirin or NSAIDs because these may precipitate GI hemorrhage.
- Advise patient to use nonhormonal contraceptive measures during and for at least 4 mo after completion of therapy and to avoid breastfeeding.
- Instruct patient not to receive any vaccinations without advice of health care professional.
- Improvement in hematologic status in patients with leukemia.
