Skin and soft tissue infection: Preterm and term neonates: IV: 22.5 mg/kg as a single dose.
Skin and soft tissue infection:
Infants and Children <6 years: IV: 22.5 mg/kg as a single dose; maximum dose: 1,500 mg/dose.
Children ≥6 years and Adolescents: IV: 18 mg/kg as a single dose; maximum dose: 1,500 mg/dose.
Dosage adjustment for concomitant therapy: Significant drug interactions exist, requiring dose/frequency adjustment or avoidance. Consult drug interactions database for more information.
Altered kidney function: Infants, Children, and Adolescents: IV:
CrCl ≥30 mL/minute/1.73 m2: No adjustment necessary.
CrCl <30 mL/minute/1.73 m2: There are no pediatric-specific dosage adjustments provided in the manufacturer's labeling (has not been studied); however, adult pharmacokinetic information shows a decrease in clearance by 47% in patients with CrCl of <30 mL/minute; based on adult recommendations, dosage adjustment may be necessary in patients with CrCl <30 mL/minute not on regularly scheduled dialysis.
Hemodialysis: <6% removed by 3 hour dialysis session. There are no pediatric-specific dosage adjustments provided in the manufacturer's labeling (has not been studied); in adults with end-stage kidney disease receiving regularly scheduled hemodialysis, no adjustment is necessary and may administer without regards to timing of dialysis.
Infants, Children, and Adolescents: IV:
Mild impairment: No dosage adjustment necessary.
Moderate or severe impairment: There are no dosage adjustments provided in the manufacturer's labeling (has not been studied); use with caution.

Endocarditis, treatment, step-down therapy in patients who inject drugs (alternative agent) (off-label use):
Note: Not first-line treatment; based on expert opinion. Reserve use for patients who inject drugs who had initial clinical improvement with IV treatment for S. aureus infection but cannot complete IV standard of care therapy and are unable to absorb oral antibiotics (Ref).
IV: 1 g as a single dose, followed by 500 mg weekly or 1.5 g as a single dose followed by 1 g every other week for a total duration, including initial IV therapy, of 6 weeks (Ref).
Skin and soft tissue infection (alternative agent):
Note: Reserve for patients with or at risk for methicillin-resistant S. aureus infection who cannot receive preferred agents (Ref).
IV: 1.5 g as a single dose (Ref) or 1 g as a single dose initially, followed by 500 mg as a single dose 1 week later (Ref); the single dose has been shown to be as effective as the two-dose regimen (Ref).

Hypersensitivity to dalbavancin or any component of the formulation
Concerns related to adverse effects:
• Hepatic effects: Patients with normal baseline transaminase levels may have ALT elevation >3 times the upper limit of normal (ULN) during therapy; in clinical studies, abnormalities in liver tests (ALT, AST, bilirubin) were reported with similar frequency in the dalbavancin and comparator arms. ALT elevations were reversible after discontinuation.
• Hypersensitivity reactions: Serious hypersensitivity (anaphylactic) and skin reactions have been reported with dalbavancin. Discontinue treatment if an allergic reaction occurs. Dalbavancin cross-sensitivity to other glycopeptides may occur; exercise caution in patients with a history of glycopeptide allergy; carefully screen for previous hypersensitivity reactions to glycopeptides prior to administration.
• Infusion reactions: Rapid intravenous infusions of dalbavancin (<30 minutes) may cause reactions that resemble vancomycin infusion reaction (formerly "red man syndrome") (eg, flushing of the upper body, urticaria, pruritus, rash). Stopping or slowing the infusion may result in cessation of these reactions (Alvarez-Arango 2021).
• Superinfection: Use may result in fungal or bacterial superinfection, including Clostridioides difficile-associated diarrhea (CDAD) and pseudomembranous colitis; CDAD has been observed >2 months postantibiotic treatment.
Disease-related concerns:
• Hepatic impairment: Use with caution in patients with moderate to severe hepatic impairment (Child-Pugh class B or C).

Adverse events have been observed in animal reproduction studies.
Information related to dalbavancin in pregnancy is limited. A case report describes use of dalbavancin for ~4 weeks during the last month of pregnancy for the treatment of methicillin-resistant S. aureus endocarditis. Treatment was unsuccessful. Following therapy, blood cultures grew vancomycin-intermediate S. aureus requiring treatment with multiple antibiotics (Steele 2018). The long half-life of dalbavancin should be considered when evaluating potential exposure to the fetus.
Renal function (BUN, serum creatinine); liver function tests (AST, ALT, bilirubin); number and type of stools/day for diarrhea. Monitor patients for any infusion-related reactions and for superinfection during therapy.
Dalbavancin is a lipoglycopeptide which binds to the D-alanyl-D-alanine terminus of the stem pentapeptide in nascent cell wall peptidoglycan, preventing cross-linking and interfering with cell wall synthesis. It is bactericidal in vitro against Staphylococcus aureus and Streptococcus pyogenes
Distribution: Vd: 7 to 13 L (Leighton, 2004)
Protein binding: 93% (primarily to albumin)
Metabolism: Minor metabolite (hydroxy-dalbavancin)
Half-life elimination: 346 hours
Excretion: Urine (33% as unchanged drug, 12% as hydroxy metabolite); feces (20%)
Altered kidney function: Mean plasma clearance reduced 11%, 35%, and 47% in subjects with mild (CrCl 50 to 79 mL/minute), moderate (CrCl 30 to 49 mL/minute), and severe (CrCl <30 mL/minute) renal impairment, respectively.
Hepatic function impairment: Mean AUC0-336 hrs decreased 28% and 31% in Child-Pugh class B and C patients, respectively.
