Warnings
Important safety information
Anaphylaxis/hypersensitivity reactions (including life-threatening): Discontinue Daptomycin in Sodium Chloride Injection and treat signs/symptoms. (5.1) • Myopathy and rhabdomyolysis: Monitor CPK levels and follow muscle pain or weakness; if elevated CPK or myopathy occurs, consider discontinuation of Daptomycin in Sodium Chloride Injection. (5.2) • Eosinophilic pneumonia: Discontinue Daptomycin in Sodium Chloride Injection and consider treatment with systemic steroids. (5.3) • Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS): Discontinue Daptomycin in Sodium Chloride Injection and institute appropriate treatment. (5.4) • Tubulointerstitial Nephritis (TIN): Discontinue Daptomycin in Sodium Chloride Injection and institute appropriate treatment. (5.5) • Peripheral neuropathy: Monitor for neuropathy and consider discontinuation. (5.6) • Potential nervous system and/or muscular system effects in pediatric patients younger than 12 months: Avoid use of Daptomycin in Sodium Chloride Injection in this age group. (5.7) • Clostridioides difficile– associated diarrhea: Evaluate patients if diarrhea occurs. (5.8) • Persisting or relapsing S. aureus bacteremia/endocarditis: Perform susceptibility testing and rule out sequestered foci of infection. (5.9) • Decreased efficacy was observed in adult patients with moderate baseline renal impairment. (5.10) 5.1 Anaphylaxis/Hypersensitivity Reactions Anaphylaxis/hypersensitivity reactions have been reported with the use of antibacterial agents, including daptomycin for injection, and may be life-threatening. If an allergic reaction to Daptomycin in Sodium Chloride Injection occurs, discontinue the drug and institute appropriate therapy [see Adverse Reactions (6.2) ]. 5.2 Myopathy and Rhabdomyolysis Myopathy, defined as muscle aching or muscle weakness in conjunction with increases in creatine phosphokinase (CPK) values to greater than 10 times the upper limit of normal (ULN), has been reported with the use of daptomycin for injection. Rhabdomyolysis, with or without acute renal failure, has been reported [see Adverse Reactions (6.2) ] . Patients receiving Daptomycin in Sodium Chloride Injection should be monitored for the development of muscle pain or weakness, particularly of the distal extremities. In patients who receive Daptomycin in Sodium Chloride Injection, CPK levels should be monitored weekly, and more frequently in patients who received recent prior or concomitant therapy with an HMG-CoA reductase inhibitor or in whom elevations in CPK occur during treatment with Daptomycin in Sodium Chloride Injection. In adult patients with renal impairment, both renal function and CPK should be monitored more frequently than once weekly [see Use in Specific Populations (8.6) and Clinical Pharmacology (12.3) ]. In Phase 1 studies and Phase 2 clinical trials in adults, CPK elevations appeared to be more frequent when daptomycin for injection was dosed more than once daily. Therefore, Daptomycin in Sodium Chloride Injection should not be dosed more frequently than once a day. Daptomycin in Sodium Chloride Injection should be discontinued in patients with unexplained signs and symptoms of myopathy in conjunction with CPK elevations to levels >1,000 U/L (~5× ULN), and in patients without reported symptoms who have marked elevations in CPK, with levels >2,000 U/L (≥10× ULN). In addition, consideration should be given to suspending agents associated with rhabdomyolysis, such as HMG-CoA reductase inhibitors, temporarily in patients receiving Daptomycin in Sodium Chloride Injection [see Drug Interactions (7.1) ]. 5.3 Eosinophilic Pneumonia Eosinophilic pneumonia has been reported in patients receiving daptomycin for injection [see Adverse Reactions (6.2) ]. In reported cases associated with daptomycin for injection, patients developed fever, dyspnea with hypoxic respiratory insufficiency, and diffuse pulmonary infiltrates or organizing pneumonia. In general, patients developed eosinophilic pneumonia 2 to 4 weeks after starting daptomycin for injection and improved when daptomycin for injection was discontinued and steroid therapy was initiated. Recurrence of eosinophilic pneumonia upon re-exposure has been reported. Patients who develop these signs and symptoms while receiving Daptomycin in Sodium Chloride Injection should undergo prompt medical evaluation, and Daptomycin in Sodium Chloride Injection should be discontinued immediately. Treatment with systemic steroids is recommended. 5.4 Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS) DRESS has been reported in post-marketing experience with daptomycin for injection [see Adverse Reactions (6.2) ] . Patients who develop skin rash, fever, peripheral eosinophilia, and systemic organ (for example, hepatic, renal, pulmonary) impairment while receiving Daptomycin in Sodium Chloride Injection should undergo medical evaluation. If DRESS is suspected, discontinue Daptomycin in Sodium Chloride Injection promptly and institute appropriate treatment. 5.5 Tubulointerstitial Nephritis (TIN) TIN has been reported in post-marketing experience with daptomycin for injection [see Adverse Reactions (6.2) ] . Patients who develop new or worsening renal impairment while receiving Daptomycin in Sodium Chloride Injection should undergo medical evaluation. If TIN is suspected, discontinue Daptomycin in Sodium Chloride Injection promptly and institute appropriate treatment. 5.6 Peripheral Neuropathy Cases of peripheral neuropathy have been reported during the daptomycin for injection postmarketing experience [see Adverse Reactions (6.2) ]. Therefore, physicians should be alert to signs and symptoms of peripheral neuropathy in patients receiving Daptomycin in Sodium Chloride Injection. Monitor for neuropathy and consider discontinuation. 5.7 Potential Nervous System and/or Muscular System Effects in Pediatric Patients Younger than 12 Months Avoid use of Daptomycin in Sodium Chloride Injection in pediatric patients younger than 12 months due to the risk of potential effects on muscular, neuromuscular, and/or nervous systems (either peripheral and/or central) observed in neonatal dogs with intravenous daptomycin [see Nonclinical Toxicology (13.2) ]. 5.8 Clostridioides difficile -Associated Diarrhea Clostridioides difficile –associated diarrhea (CDAD) has been reported with the use of nearly all systemic antibacterial agents, including daptomycin for injection, and may range in severity from mild diarrhea to fatal colitis [see Adverse Reactions (6.2) ]. Treatment with antibacterial agents alters the normal flora of the colon, leading to overgrowth of C. difficile . C. difficile produces toxins A and B, which contribute to the development of CDAD. Hypertoxin-producing strains of C. difficile cause increased morbidity and mortality, since these infections can be refractory to antimicrobial therapy and may require colectomy. CDAD must be considered in all patients who present with diarrhea following antibacterial use. Careful medical history is necessary because CDAD has been reported to occur more than 2 months after the administration of antibacterial agents. If CDAD is suspected or confirmed, ongoing antibacterial use not directed against C. difficile may need to be discontinued. Appropriate fluid and electrolyte management, protein supplementation, antibacterial treatment of C. difficile , and surgical evaluation should be instituted as clinically indicated. 5.9 Persisting or Relapsing S. aureus Bacteremia/Endocarditis Patients with persisting or relapsing S. aureus bacteremia/endocarditis or poor clinical response should have repeat blood cultures. If a blood culture is positive for S. aureus , minimum inhibitory concentration (MIC) susceptibility testing of the isolate should be performed using a standardized procedure, and diagnostic evaluation of the patient should be performed to rule out sequestered foci of infection. Appropriate surgical intervention (e.g., debridement,…
Who should not take Dapzura Rt
Daptomycin in Sodium Chloride Injection is contraindicated in patients with known hypersensitivity to daptomycin [see Warnings and Precautions (5.1) ]. • Known hypersensitivity to daptomycin (4)
Overdose — what happens if you take too much
In the event of overdosage, supportive care is advised with maintenance of glomerular filtration. Daptomycin is cleared slowly from the body by hemodialysis (approximately 15% of the administered dose is removed over 4 hours) and by peritoneal dialysis (approximately 11% of the administered dose is removed over 48 hours). The use of high-flux dialysis membranes during 4 hours of hemodialysis may increase the percentage of dose removed compared with that removed by low-flux membranes.

Interactions
7.1 HMG-CoA Reductase Inhibitors In healthy adult subjects, concomitant administration of daptomycin for injection and simvastatin had no effect on plasma trough concentrations of simvastatin, and there were no reports of skeletal myopathy [see Clinical Pharmacology (12.3) ]. However, inhibitors of HMG-CoA reductase may cause myopathy, which is manifested as muscle pain or weakness associated with elevated levels of creatine phosphokinase (CPK). In the adult Phase 3 S. aureus bacteremia/endocarditis trial, some patients who received prior or concomitant treatment with an HMG-CoA reductase inhibitor developed elevated CPK [see Adverse Reactions (6.1) ]. Experience with the coadministration of HMG-CoA reductase inhibitors and daptomycin for injection in patients is limited; therefore, consideration should be given to suspending use of HMG-CoA reductase inhibitors temporarily in patients receiving Daptomycin in Sodium Chloride Injection. 7.2 Drug-Laboratory Test Interactions Clinically relevant plasma concentrations of daptomycin have been observed to cause a significant concentration-dependent false prolongation of prothrombin time (PT) and elevation of International Normalized Ratio (INR) when certain recombinant thromboplastin reagents are utilized for the assay. The possibility of an erroneously elevated PT/INR result due to interaction with a recombinant thromboplastin reagent may be minimized by drawing specimens for PT or INR testing near the time of trough plasma concentrations of daptomycin. However, sufficient daptomycin concentrations may be present at trough to cause interaction. If confronted with an abnormally high PT/INR result in a patient being treated with Daptomycin in Sodium Chloride Injection, it is recommended that clinicians: 1. Repeat the assessment of PT/INR, requesting that the specimen be drawn just prior to the next Daptomycin in Sodium Chloride Injection dose (i.e., at trough concentration). If the PT/INR value obtained at trough remains substantially elevated above what would otherwise be expected, consider evaluating PT/INR utilizing an alternative method. 2. Evaluate for other causes of abnormally elevated PT/INR results.
