Route/Dosage ⬆ ⬇

IV (Adults ): 1500 mg as a single dose or 1000 mg followed 1 wk later by 500 mg.
IV (Children 6–<18 yr): CCr ≥30 mL/min/1.73 m²: 18 mg/kg (max dose = 1500 mg) as a single dose.
IV (Children Birth–<6 yr): CCr ≥30 mL/min/1.73 m²: 22.5 mg/kg (max dose = 1500 mg) as a single dose.

Renal Impairment

IV (Adults ): CCr <30 mL/min (with no hemodialysis): 1125 mg as a single dose or 750 mg followed 1 wk later by 375 mg.

Availability ⬆ ⬇

Lyophilized powder for injection: 500 mg/vial

Assessment ⬆ ⬇

Assess for infection (vital signs; appearance of wound, sputum, urine, and stool; WBC) at beginning of and during therapy.
Obtain specimens for culture and sensitivity prior to therapy. First dose may be given before receiving results.
Monitor bowel function. Diarrhea, abdominal cramping, fever, and bloody stools should be reported to health care professional promptly as a sign of CDAD. May begin up to 2 mo following cessation of therapy.
Monitor for infusion reactions (infusion-related reaction resembling vancomycin flushing syndrome: flushing of upper body, urticaria, pruritus, rash, back pain). May resolve with stopping or slowing infusion.

Lab Test Considerations:

Monitor hepatic function. May ↑ ALT, AST, and bilirubin.

Implementation ⬆ ⬇

IV Administration:

Intermittent Infusion: Reconstitution: Reconstitute each vial with 25 mL of sterile water or D5W. Alternate gentle swirling and inverting to avoid foaming until completely dissolved. Do not shake. Reconstituted vial contains a clear colorless to yellow solution. Do not administer solutions that are discolored or contain particulate matter. Diluent: Transfer reconstituted solution into D5W. Discard unused solution. May be refrigerated or kept at room temperature; do not freeze. Infuse within 48 hr of reconstitution. Do not administer solutions containing particulate matter.Concentration: 1–5 mg/mL.
Rate: Infuse over 30 min. Flush line before and after infusion with D5W; saline solutions may cause precipitation.
Y-Site Incompatibility: Do not administer other drugs through same IV line.

Patient/Family Teaching ⬆ ⬇

Explain purpose and side effects of medication to patient. Advise patient to read Patient Information before starting therapy.
Advise patient to notify health care professional of all Rx or OTC medications, vitamins, or herbal products being taken and to consult with health care professional before taking other medications.
Instruct patient to notify health care professional if signs and symptoms of hypersensitivity reactions (rash, hives, dyspnea, facial swelling) occur.
Instruct patient to notify health care professional immediately if diarrhea, abdominal cramping, fever, or bloody stools occur and not to treat with antidiarrheals without consulting health care professionals.
Instruct the patient to notify health care professional if symptoms do not improve.
Rep: Advise women of reproductive potential to notify health care professional if pregnancy is planned or suspected or if breastfeeding.
