Indications for: CUBICIN RF
Susceptible complicated skin and skin structure infections (cSSSI) in adults and pediatrics (1–17yrs). S. aureus bacteremia in adults (including MRSA and MSSA right-sided endocarditis) and in pediatrics (1–17yrs).
Limitations of Use:
Not for treatment of pneumonia or left-sided endocarditis due to S. aureus. Not studied in prosthetic valve endocarditis. Not recommended in pediatrics (<1yr) due to risk of potential effects on muscular, neuromuscular, and/or nervous systems (peripheral and/or central).
Give by IV inj over 2mins or IV infusion over 30mins. cSSSI: 4mg/kg once every 24hrs for 7–14 days. S. aureus bacteremia or endocarditis: 6mg/kg once every 24hrs for 2–6 weeks. Renal impairment (CrCl <30mL/min): decrease dosing interval to once every 48hrs; coincide dose for after dialysis.
<1yr: not recommended. Give by IV infusion over 60mins (1–6yrs) or 30mins (7–17yrs). cSSSI (1–<2yrs): 10mg/kg once every 24hrs; (2–6yrs): 9mg/kg once every 24hrs; (7–11yrs): 7mg/kg once every 24hrs; (12–17yrs): 5mg/kg once every 24hrs. Treat up to 14 days. S. aureus bacteremia (1–6yrs): 12mg/kg once every 24hrs; (7–11yrs): 9mg/kg once every 24hrs; (12–17yrs): 7mg/kg once every 24hrs. Treat up to 42 days. Renal impairment (CrCl <30mL/min): not established.
CUBICIN RF Warnings/Precautions:
Monitor for development of muscle pain or weakness (esp. distal extremities). Monitor CPK weekly (more frequently in those with concomitant statin therapy or elevated CPK); discontinue if CPK (≥5×ULN) and myopathy occur, or if CPK (≥10×ULN) without myopathy occurs. Renal impairment: monitor renal function and CPK more frequently than once weekly. Discontinue immediately if eosinophilic pneumonia develops; treat with systemic steroids. Discontinue if tubulointerstitial nephritis or drug reaction with eosinophilia and systemic symptoms are suspected; treat appropriately. Monitor for neuropathy; consider discontinuation if occurs. Persisting or relapsing S. aureus bacteremia/endocarditis: repeat blood cultures and evaluate. Adults with moderate baseline renal impairment: decreased efficacy observed. Severe hepatic impairment. Pregnancy. Nursing mothers.
