Other Comments
Administration advice:
- Adult patients: Administer this drug IV either by injection over 2 minutes or by infusion over 30 minutes.
- Pediatric patients: Do not administer by injection over 2 minutes.
- For patients 1 to 6 years: Administer this drug via IV infusion over 60 minutes.
- For patients 7 to 17 years: Administer this drug via IV infusion over 30 minutes.
- Cubicin(R): Administer IV in 0.9% sodium chloride injection.
- If same IV line used for sequential infusion of other drugs, flush the line before and after infusion of this drug with a compatible IV solution.
Storage requirements:
- The 2 formulations have differences regarding storage; the manufacturer product information should be consulted and followed carefully.
- The in-use storage conditions of reconstituted and diluted solutions should not be exceeded.
- Lyophilized powder: Store original packages under refrigeration, at 2C to 8C (36F to 46F); avoid excessive heat.
- Reconstituted solution: Stable in the vial for 12 hours at room temperature and up to 48 hours when refrigerated at 2C to 8C (36F to 46F)
- Diluted solution: Stable in the infusion bag for 12 hours at room temperature and 48 hours when refrigerated
- Combined storage time (reconstituted solution in vial and diluted solution in infusion bag) should not exceed 12 hours at room temperature or 48 hours when refrigerated.
- Lyophilized powder: Store original packages at 20C to 25C (68F to 77F); excursion permitted to 15C to 30C (59F to 86F).
- In-use shelf-life with Sterile Water for Injection as diluent: 1 day (vial, syringe) or 19 hours (IV bag) at room temperature (20C to 25C [68F to 77F]) and 3 days (vial, syringe, IV bag) when refrigerated (2C to 8C [36F to 46F])
- In-use shelf-life with Bacteriostatic Water for Injection as diluent: 2 days (vial, syringe, IV bag) at room temperature and 3 days (vial) or 5 days (syringe, IV bag) when refrigerated
Reconstitution/preparation techniques:
- The 2 formulations have differences regarding reconstitution; the manufacturer product information should be consulted and followed carefully.
- Cubicin(R): Should be reconstituted with 0.9% sodium chloride injection
- Cubicin(R) RF: Should be reconstituted with Sterile Water for Injection or Bacteriostatic Water for Injection; saline-based diluents should not be used for reconstitution in the vial (resulting hyperosmotic solution may cause infusion site reactions if administered as IV injection over 2 minutes)
- Both formulations (for IV infusion): The appropriate volume of the reconstituted solution (concentration of 50 mg/mL) should be further diluted into an IV infusion bag containing the specified volume of 0.9% sodium chloride injection; the manufacturer product information should be consulted.
IV compatibility:
- Compatible IV solutions: Cubicin(R): 0.9% sodium chloride injection, lactated Ringer's injection; reconstituted Cubicin(R) RF: Sterile Water for Injection, Bacteriostatic Water for Injection, 0.9% sodium chloride injection
- Incompatible: Dextrose-containing diluents, ReadyMED(R) elastomeric infusion pumps
- Limited data regarding compatibility with other IV products; additives and other drugs should not be added to this drug or infused concurrently through the same IV line.
General:
- Appropriate specimens for microbiological examination should be obtained before therapy to isolate and identify infecting organisms and to establish susceptibility to this drug.
- Culture and susceptibility information should be considered when selecting treatment or, if no data are available, local epidemiology and susceptibility patterns may be considered when selecting empiric therapy; empiric therapy may be started before test results are known.
- Combination therapy may be clinically indicated if documented or presumed pathogens include gram-negative or anaerobic organisms.
- This drug is not indicated for the treatment of pneumonia.
- This drug is not recommended for patients younger than 1 year due to risk of potential muscular, neuromuscular, and/or nervous system (peripheral and/or central) effects seen in neonatal dogs.
Monitoring:
- Infections/Infestations: Blood cultures (repeat if persisting or relapsing S aureus bacteremia/endocarditis or poor clinical response); MIC susceptibility (if blood culture positive for S aureus)
- Musculoskeletal: For muscle pain or weakness, especially of distal extremities; creatine phosphokinase (CPK) levels (weekly; more often if CPK elevations during therapy or recent prior/concurrent HMG-CoA reductase inhibitor therapy; more than once a week in adults with renal dysfunction)
- Nervous System: For neuropathy
- Renal: Renal function (more than once a week in adults with renal dysfunction)
Patient advice:
- Avoid missing doses and complete the entire course of therapy.
- Report muscle pain or weakness (especially in forearms and lower legs), tingling or numbness, and any symptoms of cough, breathlessness, or fever.
- Consult physician at once if watery and bloody stools (with or without stomach cramps and fever) develop.
