Note: Caspofungin treatment duration should be based on patient status and clinical response.
Candidiasis, invasive infections: Limited data available: IV:
BSA-directed dosing: 25 mg/m2/dose once daily (Bradley 2019; IDSA [Pappas 2016]); dosing based on a pharmacokinetic study of 18 neonates (PNA: <12 weeks; GA ≥28 weeks (all except one patient); weight at enrollment: ≥500 g; most [n=16] were ≥1 kg); results showed similar serum concentrations to standard adult doses. Reported trough concentrations were slightly elevated and not correlated with increased adverse events (Sáez-Llorens 2009).
Weight-directed dosing: 2 mg/kg/dose once daily; treatment should continue for at least 2 weeks after the first negative blood culture and signs and symptoms have resolved (IDSA [Pappas 2016]); dosing based on a prospective, randomized, double-blind study and a case series; the prospective trial enrolled 32 patients with invasive candidiasis and randomized them to receive caspofungin (n=15; GA: 27.9 ± 1.3 weeks; PNA at onset of candida infection: 21.1 ± 3.1 days) or amphotericin B as initial treatment; results showed that the caspofungin group had a significantly higher response rate compared to the amphotericin B group (86.7% favorable response vs 41.7%); the caspofungin group also experienced significantly fewer adverse effects (Mohamed 2012); the case series included seven premature neonates (GA: 23 to 24 weeks, PNA at treatment, range: 13 to 53 days) with Candida infections refractory to amphotericin B; results showed this regimen to be effective and well tolerated for the treatment of Candida parapsilosis and Candida albicans (Jeon 2014).
Note: Caspofungin treatment duration should be based on patient status and clinical response.
Aspergillosis, invasive; treatment: Note: Guidelines recommend caspofungin for salvage therapy or where other antifungals are contraindicated; not recommended for routine use for primary treatment (IDSA [Patterson 2016]). Infants ≥3 months, Children, and Adolescents <18 years: IV: Initial 70 mg/m2/dose on day 1, then 50 mg/m2/dose once daily; may increase to 70 mg/m2/dose once daily if clinical response inadequate; maximum dose: 70 mg/dose.
Fungal infections, empiric therapy in neutropenic patients: Infants ≥3 months, Children, and Adolescents <18 years: IV: Initial dose: 70 mg/m2/dose on day 1, then 50 mg/m2/dose once daily; may increase to 70 mg/m2/dose once daily if clinical response inadequate; maximum dose: 70 mg/dose.
Fungal infections, prophylaxis in patients with acute myeloid leukemia: Limited data available: Infants ≥3 months, Children, and Adolescents: IV: Initial 70 mg/m2/dose on day 1 (maximum dose: 70 mg/dose), then 50 mg/m2/dose once daily (maximum dose: 50 mg/dose); begin therapy 24 to 72 hours following completion of each chemotherapy cycle and continue until ANC 100 to 500/µL following nadir or until next chemotherapy cycle, whichever occurs first (Fisher 2019).
Fungal infections, prophylaxis in allogeneic hematopoietic stem cell transplantation recipients: Limited data available: Infants ≥8 months, Children, and Adolescents: IV: 50 mg/m2/dose once daily; maximum dose: 50 mg/dose (Döring 2012; Iosifidis 2018); some studies used a loading dose (Maximova 2017); guidelines recommend administering antifungal prophylaxis from the start of conditioning through engraftment (Science 2014).
Candida infections, treatment; independent of HIV status:
Infants <3 months: Limited data available: IV: 25 mg/m2/dose once daily; dosing based on a pharmacokinetic study of 18 infants (PNA ≤12 weeks) that showed similar serum concentrations to standard adult doses (50 mg/day). Reported trough concentrations were slightly elevated and not correlated with increased adverse events (Sáez-Llorens 2009).
Infants ≥3 months, Children, and Adolescents <18 years: IV: Initial 70 mg/m2/dose on day 1, then 50 mg/m2/dose once daily; may increase to 70 mg/m2/dose once daily if clinical response inadequate; maximum dose: 70 mg/dose. For esophageal disease, treat 14 to 21 days (HHS [OI pediatric 2019]; IDSA [Pappas 2016]). For candidemia, treat until 2 weeks after the last positive blood culture.
Adolescents ≥18 years: IV: Initial 70 mg on day 1, then 50 mg once daily (IDSA [Pappas 2016]); for candidemia, treat until 2 weeks after the last positive blood culture and symptom resolution, and longer if neutropenia warrants; for esophageal disease, treat for 14 to 21 days. For esophageal disease, a higher rate of relapse has been reported with echinocandins than with fluconazole (HHS [OI adult 2019]). Transition to fluconazole is recommended in clinically stable patients with fluconazole-susceptible isolates and negative repeat cultures (IDSA [Pappas 2016]).
Dosage adjustment for concomitant therapy: Significant drug interactions exist, requiring dose/frequency adjustment or avoidance. Consult drug interactions database for more information.
Infants ≥3 months, Children, and Adolescents: No adjustment needed
End-stage renal disease (ESRD) requiring dialysis: Poorly dialyzed; no supplemental dose or dosage adjustment necessary in patients on intermittent hemodialysis (IHD). No supplemental dose or dosage adjustment needed in peritoneal dialysis or continuous renal replacement therapy (eg, CVVHD) (Aronoff 2007; Heintz 2009).
There are no dosage adjustments provided in the manufacturer's labeling (has not been studied); based on experience in adult patients, dosage reduction may be necessary; use with caution.

Aspergillosis, invasive (including disseminated and extrapulmonary) (alternative agent):
Note: Reserve for salvage therapy, typically as part of an appropriate combination regimen. Monotherapy is further reserved for patients who are intolerant of or refractory to azoles and polyenes (IDSA [Patterson 2016]; Maertens 2004; Patterson 2022); for patients with severe or progressive infection, some experts use as initial therapy in combination with voriconazole (Maertens 2006; Marr 2004; Patterson 2022; Singh 2006).
IV: 70 mg on day 1, then 50 mg once daily (IDSA [Patterson 2016]; Maertens 2004); if inadequate response, may increase dose to 70 mg once daily (Maertens 2006; Patterson 2022).
Duration: When given as monotherapy, the minimum duration is 6 to 12 weeks depending on degree/duration of immunosuppression, disease site, and response to therapy (IDSA [Patterson 2016]); immunosuppressed patients may require more prolonged treatment (AST-IDCOP [Husain 2019]; Patterson 2022). When given as part of a combination regimen, the optimal duration is uncertain. Some experts have given an echinocandin for ~2 weeks in combination with voriconazole before step-down to voriconazole monotherapy (Marr 2015).
Candidiasis:
Candidemia (neutropenic and nonneutropenic patients), including disseminated candidiasis: IV: 70 mg on day 1, then 50 mg once daily. Total duration (including oral step-down therapy) is ≥14 days after first negative blood culture and continues until signs/symptoms of candidemia and neutropenia, if present, have resolved; metastatic complications warrant a longer duration (AST-IDCOP [Aslam 2019]; IDSA [Pappas 2016]; Mora-Duarte 2002).
Cardiac device infection (including implantable cardiac defibrillator, pacemaker, ventricular assist device) (off-label use) : IV: 150 mg once daily; step down to azole therapy in clinically stable patients with susceptible isolates and negative repeat cultures; total antifungal duration is ≥4 weeks after device removal for isolated generator pocket infection and ≥6 weeks after device removal for wire infection (IDSA [Pappas 2016]).
Chronic disseminated (hepatosplenic) (off-label use): IV: 70 mg on day 1, then 50 mg once daily for several weeks, followed by oral azole step-down therapy until lesion resolution and through periods of immunosuppression (IDSA [Pappas 2016]).
Empiric therapy, suspected invasive candidiasis (nonneutropenic ICU patients) (off-label use):
Note: Antifungal therapy is not routinely warranted for initial management of nonneutropenic patients with sepsis. Consider use for critically ill patients with unexplained fever or unexplained hypotension despite broad-spectrum antimicrobial therapy and risk factors for invasive candidiasis (eg, indwelling venous catheter, hemodialysis, trauma or burns, recent surgery, parenteral nutrition) (IDSA [Pappas 2016]; Kauffman 2021a; SCCM [Rhodes 2017]).
IV: 70 mg on day 1, then 50 mg once daily. For those who improve, continue empiric antifungal therapy for 2 weeks; consider discontinuing after 4 to 5 days in patients with no evidence of invasive candidiasis and no clinical response (AST-IDCOP [Aslam 2019]; IDSA [Pappas 2016]).
Endocarditis, native or prosthetic valve (off-label use): IV: 150 mg once daily (Cornely 2007; IDSA [Pappas 2016]); step down to azole therapy in clinically stable patients with susceptible isolates and negative repeat cultures; total antifungal duration is ≥6 weeks after valve replacement surgery, with longer duration for perivalvular abscesses, other complications, or a nonsurgical approach (IDSA [Pappas 2016]).
Esophageal, refractory disease (alternative agent):
Note: Reserve for fluconazole-refractory disease in patients who require IV therapy (eg, severe disease) (Kauffman 2021c).
IV: 70 mg on day 1, then 50 mg once daily (AST-IDCOP [Aslam 2019]; HHS [OI adult 2021]; IDSA [Pappas 2016]; Kauffman 2021c; Villanueva 2002). Some experts do not give a loading dose (HHS [OI adult 2021]). Transition to an oral antifungal once patient tolerates oral intake if susceptibility allows; total antifungal duration is 14 to 28 days (HHS [OI adult 2021]; Kauffman 2021c; Pappas [IDSA 2016]).
Intra-abdominal infection (eg, peritonitis, abdominal abscess): IV: 70 mg on day 1, then 50 mg once daily. Total duration (including oral step-down therapy) is ≥14 days and continues until source control and clinical resolution (AST-IDCOP [Aslam 2019]; IDSA [Pappas 2016]; Mora-Duarte 2002; SIS [Mazuski 2017]).
Oropharyngeal, refractory disease (alternative therapy) (off-label use):
Note: Reserve for fluconazole-refractory disease in patients who require IV therapy (eg, severe disease) (Kauffman 2021d).
IV: 70 mg on day 1, then 50 mg once daily. Transition to an oral antifungal once patient tolerates oral intake if susceptibility allows; total antifungal duration is 14 to 28 days (IDSA [Pappas 2016]; Kauffman 2021d).
Osteoarticular infection (osteomyelitis or septic arthritis) (off-label use): IV: 70 mg on day 1, then 50 to 70 mg once daily for ≥2 weeks; total duration of therapy (including oral step-down therapy) is 6 to 12 months for osteomyelitis and ≥6 weeks for septic arthritis (IDSA [Pappas 2016]; Kauffman 2022b).
Thrombophlebitis, suppurative (off-label use): IV: 150 mg once daily; continue antifungal therapy until catheter removed and thrombus resolved, and for ≥2 weeks after candidemia (if present) has cleared (IDSA [Pappas 2016]).
Neutropenic fever, empiric antifungal therapy (alternative agent):
Note: Recommended for patients with persistent or recurrent fever after ≥4 days of antimicrobial therapy when the duration of neutropenia is expected to exceed 7 days (IDSA [Freifeld 2011]; IDSA [Patterson 2016]). Some experts reserve for patients without suspicion of mold infection (eg, pulmonary nodules) (Wingard 2021).
IV: 70 mg on day 1, then 50 mg once daily (Walsh 2004).
Prophylaxis against invasive fungal infections (off-label use):
Hematologic malignancy or hematopoietic cell transplant (alternative agent):
Note: Some experts reserve for patients at low risk for mold infection (ASCO/IDSA [Taplitz 2018]; Wingard 2021).
IV: 50 mg once daily. Duration is at least until resolution of neutropenia and varies based on degree and duration of immunosuppression (ASCO/IDSA [Taplitz 2018]; IDSA [Freifeld 2011]; IDSA [Patterson 2016]; Mattiuzzi 2006).
Solid organ transplant (alternative agent): IV: 50 mg once daily; duration varies based on patient risk factors and transplant center protocol (AST-IDCOP [Aslam 2019]; AST-IDCOP [Husain 2019]; Fishman 2021; Fortún 2016; IDSA [Patterson 2016]).
Dosage adjustment for concomitant therapy: Significant drug interactions exist, requiring dose/frequency adjustment or avoidance. Consult drug interactions database for more information.
The renal dosing recommendations are based upon the best available evidence and clinical expertise. Senior Editorial Team: Bruce Mueller, PharmD, FCCP, FASN, FNKF; Jason A. Roberts, PhD, BPharm (Hons), B App Sc, FSHP, FISAC; Michael Heung, MD, MS.
Altered kidney function: No dosage adjustment necessary for any degree of kidney dysfunction (manufacturer's labeling).
Hemodialysis, intermittent (thrice weekly): Poorly dialyzed: No supplemental dose or dosage adjustment necessary (expert opinion; manufacturer's labeling).
Peritoneal dialysis: Unlikely to be significantly dialyzed (highly protein bound): No dosage adjustment necessary (expert opinion).
CRRT: Poorly dialyzed (Aguilar 2017; Roger 2017; Weiler 2013): No dosage adjustment necessary (Weiler 2013). Note: Significant variability in caspofungin pharmacokinetics has been observed in critically ill patients (Nguyen 2007) and those on renal replacement therapies (Pérez-Pitarch 2018; Roger 2017). Results of a Monte Carlo simulation suggest that instead of standard dosing (ie, 70 mg × 1 followed by 50 mg daily), a larger loading dose (ie, 100 mg) and maintenance dose of 50 mg once daily in patients <80 kg or 70 mg once daily in patients >80 kg increases the probability of achieving pharmacodynamic targets (Roger 2017).
PIRRT (eg, sustained, low-efficiency diafiltration): Unlikely to be significantly dialyzed: No dosage adjustment necessary (expert opinion). Note: Significant variability in caspofungin pharmacokinetics has been observed in critically ill patients (Nguyen 2007) and those on renal replacement therapies (Pérez-Pitarch 2018; Roger 2017). Results of a Monte Carlo simulation suggest that instead of standard dosing (ie, 70 mg × 1 followed by 50 mg daily), a larger loading dose (ie, 100 mg) and maintenance dose of 50 mg once daily in patients <80 kg or 70 mg once daily in patients >80 kg increases the probability of achieving pharmacodynamic targets in patients on CRRT (Roger 2017); these results are likely to be applicable to critically ill patients receiving PIRRT therapies as well (expert opinion).
Mild impairment (Child-Pugh class A): No dosage adjustment necessary.
Moderate impairment (Child-Pugh class B): 70 mg on day 1 (where recommended), followed by 35 mg once daily (manufacturer's labeling; Mistry 2007); however, pharmacokinetic data suggest that this dose reduction may result in suboptimal drug exposure (Gustot 2018)
Severe impairment (Child-Pugh class C): There are no dosage adjustments provided in the manufacturer's labeling. Subsequent pharmacokinetic data suggest that degree of impairment (Child-Pugh class B or C) does not further decrease clearance of caspofungin and patients with severe impairment can be dosed the same as patients with moderate impairment (Gustot 2018).

Hypersensitivity to caspofungin or any component of the formulation
Documentation of allergenic cross-reactivity for echinocandin antifungals is limited. However, because of similarities in chemical structure and/or pharmacologic actions, the possibility of cross-sensitivity cannot be ruled out with certainty.
Concerns related to adverse effects:
• Hepatic effects: Increased transaminases and rare cases of clinically significant hepatic dysfunction (including failure and hepatitis) have been reported in pediatric and adult patients. Monitor liver function tests during therapy; if tests become abnormal or worsen, consider discontinuation.
• Hypersensitivity: Anaphylaxis, other hypersensitivity reactions, histamine-related reactions (eg, angioedema, facial swelling, bronchospasm, rash, sensation of warmth), and cases of Stevens-Johnson syndrome and toxic epidermal necrolysis (some fatal) have been reported. Discontinue if a hypersensitivity reaction occurs. Administer supportive treatment if needed.
Disease-related concerns:
• Hepatic impairment: Use with caution in patients with hepatic impairment. Dosage reduction may be necessary in adults with moderate impairment (Child-Pugh class B); safety and efficacy have not been established in children with any degree of hepatic impairment and adults with severe impairment (Child-Pugh class C).
Special populations:
• Obesity: Data with another echinocandin suggest that clearance increases as a function of weight; higher doses may be necessary in patients with obesity (Hall 2011).
None known.
CycloSPORINE (Systemic): May enhance the adverse/toxic effect of Caspofungin. CycloSPORINE (Systemic) may increase the serum concentration of Caspofungin. Caspofungin may increase the serum concentration of CycloSPORINE (Systemic). Management: Weigh potential benefits of caspofungin against a possible elevated risk of hepatotoxicity. Monitor liver function and re-evaluate treatment in patients with abnormal values. Mild transaminase elevations may occur relatively commonly. Risk D: Consider therapy modification
Inducers of Drug Clearance: May decrease the serum concentration of Caspofungin. Management: Consider using an increased caspofungin dose of 70 mg daily in adults (or 70 mg/m2, up to a maximum of 70 mg, daily in pediatric patients) when coadministered with known inducers of drug clearance. Risk D: Consider therapy modification
RifAMPin: May decrease the serum concentration of Caspofungin. Management: Caspofungin prescribing information recommends using a dose of 70 mg daily in adults (or 70 mg/m2, up to a maximum of 70 mg, daily in pediatric patients) who are also receiving rifampin. Risk D: Consider therapy modification
Saccharomyces boulardii: Antifungal Agents (Systemic, Oral) may diminish the therapeutic effect of Saccharomyces boulardii. Risk X: Avoid combination
Based on animal data, in utero exposure to caspofungin may cause fetal harm.
When treatment of invasive Aspergillus or Candida infections is needed during pregnancy, other agents are preferred (HHS [OI adult 2020]; IDSA [Pappas 2016]).
Periodic liver function tests, serum potassium, CBC, hemoglobin; signs of anaphylaxis or histamine-related reactions
Inhibits synthesis of β(1,3)-D-glucan, an essential component of the cell wall of susceptible fungi. Highest activity is in regions of active cell growth. Mammalian cells do not require β(1,3)-D-glucan, limiting potential toxicity.
Distribution: CSF concentrations: Nondetectable [<10 ng/mL (n=1)] (Sáez-Llorens 2009)
Protein binding: ~97% to albumin
Metabolism: Slowly, via hydrolysis and N-acetylation as well as by spontaneous degradation, with subsequent metabolism to component amino acids. Overall metabolism is extensive.
Half-life elimination: Beta (distribution): 9 to 11 hours (~8 hours in children <12 years); Terminal: 40 to 50 hours; beta phase half-life is 32% to 43% lower in pediatric patients than in adult patients
Excretion: Urine (41%; primarily as metabolites, ~1% of total dose as unchanged drug); feces (35%; primarily as metabolites)
Renal function impairment: AUC is increased 30% to 49% in patients with CrCl ≤49 mL/minute after administration of a single 70 mg dose. No effect on caspofungin concentrations was seen in patients with mild to end-stage renal impairment after administration of multiple daily doses.
Hepatic function impairment: AUC is increased by ~55% in patients with mild hepatic impairment (Child-Pugh class A) and by 76% in patients with moderate hepatic impairment (Child-Pugh class B).
Geriatric: AUC is increased by ~28%.
Gender: AUC in women was ~22% higher than in men after repeat dosing.
Obesity: Data with another echinocandin suggest that clearance increases as a function of weight (Hall 2011). From a small study of patients receiving caspofungin in the surgical ICU, body weight >75 kg was an independent predictor for a lower 24-hour trough concentration (Nguyen 2007).
