Contraindications
Pregnancy
All indications: Hypersensitivity, including rare cases of urticaria, angioedema, and anaphylactic reaction or shock
Nononcologic uses: Hypocalcemia, severe renal impairment (CrCl <35 mL/min or evidence of acute renal impairment)
Cautions
Assess renal function before and after treatment; if renal function is decreased after treatment, withhold additional treatment until it returns to within 10% of baseline
Before each Reclast dose, calculate CrCl on basis of actual body weight, using Cockcroft-Gault formula
Other risks for renal impairment include coadministration of zoledronic acid with nephrotoxic or diuretic medications, severe dehydration before or after zoledronic acid administration, and advanced age
Previous renal insufficiency (serum creatinine >3 mg/dL [265 mmol/L]), hepatic insufficiency, musculoskeletal pain
Infuse over ≥15 minutes; faster infusion increases renal toxicity
May cause significant risk of hypocalcemia (seizures, tetany, and numbness); hypocalcemia must be corrected before initiation of therapy; adequately supplement patients with calcium and vitamin D; monitor serum calcium closely with concomitant administration of other drugs known to cause hypocalcemia to avoid severe or life-threatening hypocalcemia
Use with caution in aspirin-sensitive asthma; may cause bronchoconstriction
Increased risk of osteonecrosis of jaw (advise patients against dental work); reported predominantly in cancer patients treated with IV bisphosphonates, including zoledronic acid; many patients were also receiving chemotherapy and corticosteroids which may be risk factors; risk may increase with duration of exposure to bisphosphonates; perform preventive dental exams before initiating therapy; avoid invasive dental procedures; monitor diabetic patients carefully
Cases of osteonecrosis (primarily involving the jaw but also of other anatomical sites including hip, femur and external auditory canal) reported predominantly in cancer patients
Risk of osteonecrosis of the jaw may increase with duration of exposure to bisphosphonates
Possible increased risk for atypical subtrochanteric and diaphyseal femur fractures; consider periodic reevaluation of need for continued bisphosphonate therapy, particularly if treatment lasts >5 years
If patients are receiving Zometa, they should not receive Reclast
Severe bone, joint, and muscle pain may occur; withhold future doses of zoledronic acid if severe symptoms occur
Rehydrate patients with hypercalcemia of malignancy prior to administration of zoledronic acid injection and monitor electrolytes during treatment
Women of childbearing age should be advised of potential hazard to fetus and avoid becoming pregnant
Femur Fractures reported; patients with thigh or groin pain should be evaluated to rule out a femoral fracture
Severe bone, joint, and muscle pain may occur; withhold future doses of reclast if severe symptoms occur
Pregnancy & Lactation
Pregnancy
There are no available data in pregnant women to inform the drug-associated risk
Bisphosphonates are incorporated into bone matrix and are gradually released over periods of weeks to years; there may be a risk of fetal harm (e.g., skeletal and other abnormalities) if a woman becomes pregnant after completing a course of bisphosphonate therapy; advise pregnant women and females of reproductive potential of the potential risk to a fetus
Verify pregnancy status of females of reproductive potential prior to initiation of therapy
Therapy can cause fetal harm when administered to a pregnant woman; drug binds to bone long term and may be released over weeks to years; advise females of reproductive potential to use effective contraception during and after therapy
Based on animal studies, therapy may impair fertility in females of reproductive potential
Animal data
- Based on findings from animal studies and its mechanism of action, drug can cause fetal harm when administered to a pregnant woman; in animal reproduction studies, administration of drug to pregnant rats during organogenesis resulted in fetal malformations and embryo-fetal lethality at maternal exposures that were greater than or equal to 2.4 times the human clinical exposure based on AUC
Lactation
Not known whether drug is present in human milk, or whether it affects milk production, or breastfed child; drug binds to bone long term and may be released over weeks to years
Consider developmental and health benefits of breast-feeding along with the mother’s clinical need for therapy and any potential adverse effects on breast-fed child from drug or from underlying maternal condition
Pregnancy Categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk. C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done. D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk. X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist. NA: Information not available.Pharmacology

ZOLEDRONIC ACID - INJECTION
(ZOLE-eh-dron-ick)
COMMON BRAND NAME(S): Zometa
USES: This medication is used to treat high blood calcium levels (hypercalcemia) that may occur with cancer. Zoledronic acid is also used with cancer chemotherapy to treat bone problems that may occur with multiple myeloma and other types of cancer (such as breast, lung) that have spread to the bones. Zoledronic acid belongs to a class of drugs known as bisphosphonates. It lowers high blood calcium levels by reducing the amount of calcium released from your bones into your blood. It also works by slowing the breakdown of your bones by cancer to prevent bone fractures.
HOW TO USE: Read the Patient Information Leaflet if available from your pharmacist before you start receiving zoledronic acid and each time you get a treatment. If you have any questions, ask your doctor or pharmacist.This medication is given by injection into a vein as directed by your doctor, usually over at least 15 minutes. The dosage is based on your medical condition and response to treatment.If you are giving this medication to yourself at home, learn all preparation and usage instructions from your health care professional. Before using, check this product visually for particles or discoloration. If either is present, do not use the liquid. Learn how to store and discard medical supplies safely.Avoid mixing zoledronic acid with IV fluids that have calcium in them (such as Ringer's solution, Hartmann's solution, parenteral nutrition-TPN/PPN). Talk to your pharmacist for more details.For the treatment of high blood calcium levels, fluids are usually given through a vein before you receive this medication. To decrease the chance of kidney problems, drink plenty of fluids during treatment unless otherwise directed by your doctor. It takes at least 7 days after a dose to get the full benefit of this drug. The dose may need to be repeated depending on your blood calcium levels.For the treatment of multiple myeloma and bone problems caused by the spread of cancer, this medication is given as directed by your doctor, usually every 3 to 4 weeks.
