The InterventionZ program was developed by Novartis in 2005 to mobilize healthcare professionals to more proactively address the treatment of patients with bone complications from cancer who are taking ZOMETA, and to support oncology nurses and physician assistants caring for these patients. The information provided through this program is based on the guidance of faculty advisors and feedback from nurses like you. It is this closed loop that creates a program that is for nurses, by nurses. Currently InterventionZ has more than 4,000 nursing professionals who have completed the Bone Health Counselor accreditation program.
Benefit from All That
InterventionZ Has to Offer
ZOMETA is contraindicated in patients with hypersensitivity to zoledronic acid or any components of ZOMETA. Hypersensitivity reactions, including rare cases of urticaria and angioedema, and very rare cases of anaphylactic reaction/shock, have been reported. Patients being treated with ZOMETA should not be treated with Reclast® (zoledronic acid) as they contain the same active ingredient.
Patients with HCM must be adequately rehydrated prior to use of ZOMETA and loop diuretics (if applicable). Loop diuretics should be used with caution in combination with ZOMETA to avoid hypocalcemia. ZOMETA should be used with caution with other nephrotoxic drugs. Carefully monitor serum calcium, phosphate, magnesium, and serum creatinine following initiation of ZOMETA. Short-term supplemental therapy may be necessary.
In patients with impaired renal function, the risk of adverse reactions (especially renal adverse reactions) may be greater. Consider individual patient risk/benefit profile before starting ZOMETA therapy in HCM patients with severe renal impairment. ZOMETA treatment is not recommended in patients with bone metastases with severe renal impairment. Preexisting renal insufficiency and multiple cycles of ZOMETA and other bisphosphonates are risk factors for subsequent renal deterioration with ZOMETA. Do not use doses greater than 4 mg. ZOMETA should be administered by IV infusion over no less than 15 minutes. Monitor serum creatinine before each dose.
Osteonecrosis of the jaw (ONJ) has been reported predominantly in cancer patients treated with intravenous bisphosphonates, including ZOMETA. Many of these patients were also receiving chemotherapy and corticosteroids, which may be risk factors for ONJ. Postmarketing experience and the literature suggest a greater frequency of reports of ONJ based on tumor type (advanced breast cancer, multiple myeloma) and dental status (dental extraction, periodontal disease, local trauma, including poorly fitting dentures). Many reports of ONJ involved patients with signs of local infection, including osteomyelitis. Cancer patients should maintain good oral hygiene and should have a dental examination with preventive dentistry prior to treatment with bisphosphonates. While on treatment, these patients should avoid invasive dental procedures, if possible, as recovery may be prolonged. For patients who develop ONJ while on bisphosphonate therapy, dental surgery may exacerbate the condition. For patients requiring dental procedures, there are no data available to suggest whether discontinuation of bisphosphonate treatment reduces the risk of ONJ. A causal relationship between bisphosphonate use and ONJ has not been established. Clinical judgment of the treating physician should guide the management plan of each patient based on individual benefit/risk assessment.
ZOMETA should not be used during pregnancy. Women of childbearing potential should be advised to avoid becoming pregnant. If the patient becomes pregnant or plans to breast-feed while taking this drug, the patient should be apprised of the potential harm to the fetus or baby.
In postmarketing experience, severe and occasionally incapacitating bone, joint, and/or muscle pain has been reported in patients taking bisphosphonates including ZOMETA. Discontinue use if severe symptoms develop, and a subset of patients had recurrence of symptoms when rechallenged with the same drug or another bisphosphonate. There have been reports of bronchoconstriction in aspirin sensitive patients receiving bisphosphonates.
Insufficient data exist on how to safely use ZOMETA in HCM patients with hepatic impairment.
Acute-phase reaction symptoms can occur in HCM patients, with fever most commonly reported (44% with ZOMETA vs. 33% with pamidronate). Patients may occasionally experience flu-like syndrome (fever, chills, flushing, bone pain and/or arthralgias and myalgias). The most common adverse events (≥10%) in HCM clinical trials, regardless of causality, with ZOMETA 4 mg (n=86) were as follows: fever (44%), nausea (29%), constipation (27%), anemia (22%), dyspnea (22%), diarrhea (17%), abdominal pain (16%), progression of cancer (16%), insomnia (15%), vomiting (14%), anxiety (14%), urinary tract infection (14%), hypophosphatemia (13%), confusion (13%), agitation (13%), moniliasis (12%), hypokalemia (12%), coughing (12%), skeletal pain (12%), hypotension (11%), and hypomagnesemia (11%). In controlled HCM clinical trials, adverse events (5-10% frequency) occurring in greater incidence with ZOMETA than pamidronate include: asthenia, chest pain, leg edema, mucositis, dysphagia, granulocytopenia, thrombocytopenia, pancytopenia, non-specific infection, hypocalcemia, dehydration, arthralgias, headache and somnolence. Injection site reactions (redness, swelling) have been infrequently reported.
The most common adverse events (≥15%) in bone metastases clinical trials, regardless of causality, with ZOMETA 4 mg (n=1031) were as follows: bone pain (55%), nausea (46%), fatigue (39%), anemia (33%), pyrexia (32%), vomiting (32%), constipation (31%), dyspnea (27%), diarrhea (24%), weakness (24%), myalgia (23%), anorexia (22%), cough (22%), arthralgia (21%), lower-limb edema (21%), malignant neoplasm aggravated (20%), headache (19%), dizziness (excluding vertigo) (18%), insomnia (16%), decreased weight (16%), back pain (15%), and paresthesia (15%). Patients should also be made aware of the potential for abdominal pain.
Ocular adverse events may occur with bisphosphonates, including ZOMETA. Cases of uveitis, scleritis, episcleritis, conjunctivitis, iritis, and orbital inflammation including orbital edema have been reported during postmarketing use. In some cases, symptoms resolved with topical steroids.
Caution is advised when bisphosphonates, including ZOMETA, are administered with aminoglycosides, loop diuretics, and potentially nephrotoxic drugs.
Patients with multiple myeloma and bone metastases due to solid tumors should be administered an oral calcium supplement of 500 mg and a multiple vitamin containing 400 IU of vitamin D daily.
