Pediatric patients (alternative)†
Administer usual loading dose, then reduce maintenance dose by 50% and administer every 48 hours (after dialysis).[32569]
Peritoneal dialysis†
Adults
Administer usual loading dose, then reduce maintenance dose by 50%.[32569]
Pediatric patients
Administer usual loading dose, then reduce maintenance dose by 50% and administer every 48 hours.[32569]
Continuous renal replacement therapy (CRRT)†
NOTE: Various CRRT modalities include continuous venovenous hemofiltration (CVVH), continuous venovenous hemodialysis (CVVHD), continuous venovenous hemodiafiltration (CVVHDF), continuous venovenous high-flux hemodialysis (CVVHFD), continuous arteriovenous hemofiltration (CAVH), continuous arteriovenous hemodialysis (CAVHD), and continuous arteriovenous hemodiafiltration (CAVHDF). Dosing should take into consideration patient-specific factors (e.g., intrinsic renal function), type of infection, the duration of renal replacement therapy, the effluent flow rate, and the replacement solution administered.[42303]
Adults
200 to 400 mg IV or PO every 24 hours has generally been suggested for CRRT.[32569] Specific recommendations for patients receiving CVVH, CVVHD, or CVVHD include the following:
CVVH: 400 to 800 mg IV or PO loading dose, then 200 to 400 mg IV or PO every 24 hours.[34038][42303]
CVVHD or CVVHDF: 400 mg to 800 mg IV or PO every 24 hours. If the dialysate flow rate is 2 L/hour or more and/or if treating relatively resistant organisms, 800 mg IV or PO every 24 hours.[34038][42303]
Pediatric patients
Pediatric recommendations are based on limited study data, mainly derived from adult patients, and extrapolation of CRRT clearance based on fluconazole pharmacokinetic parameters.[67116]
6 mg/kg/dose IV or PO every 24 hours has generally been suggested for CRRT.[32569] Specific recommendations for patients receiving CAVH/CVVH and CAVHD/CVVHD based on dialysate flow rate include the following:
Dialysate flow rate (ultrafiltration rate + dialysis inflow rate) less than 1,500 mL/m2/hour: Administer usual loading dose, then 3 to 12 mg/kg/dose IV or PO every 24 hours.
Dialysate flow rate (ultrafiltration rate + dialysis inflow rate) 1,500 mL/m2/hour or more: Administer usual loading dose, then 6 to 12 mg/kg/dose IV or PO every 24 hours.[67116]
Hybrid hemodialysis†
NOTE: Hybrid treatments include prolonged intermittent renal replacement therapy (PIRRT), sustained low-efficiency dialysis (SLED), slow extended daily dialysis/diafiltration (SLEDD-f), and extended daily dialysis (EDD). Dosing should take into consideration patient-specific factors (e.g., intrinsic renal function), the type of infection, the duration of renal replacement therapy, the ultrafiltration rate, the dialysis flow rate, and how often dialysis sessions occur.[65397]
Adults
800 mg IV loading dose, then 400 mg IV every 12 hours or pre- and post-PIRRT achieved at least a 90% probability of pharmacodynamic target attainment for C. albicans for an 8- to 10-hour PIRRT session. Dosing was studied using 4 different PIRRT setting simulations over 8 to 10 hours/day in a Monte Carlo simulation study using population pharmacokinetic data.[65424]
Pediatric patients
Fluconazole dosing data are not available in pediatric patients receiving hybrid hemodialysis. Based on adult data, dosage adjustments may be necessary.[65424]
† Off-label indicationFluconazole is a synthetic antifungal agent of the triazole class. It is administered orally and intravenously. The antifungal spectrum for fluconazole is broader than that of the imidazole antifungals class, which includes agents such as ketoconazole, miconazole, and clotrimazole. Fluconazole is more resistant to first-pass metabolism and has lower lipophilicity and protein binding than does ketoconazole. Unlike ketoconazole, the oral absorption of fluconazole is not affected by the absence of stomach acid. Fluconazole is approved for the treatment of a variety of infections caused by Candida and for the treatment of cryptococcal meningitis. Additionally, fluconazole is indicated to decrease the incidence of candidiasis in patients undergoing bone marrow transplant who receive chemotherapy and/or radiation therapy.[28674] Fluconazole has been shown equivalent to amphotericin B in the treatment of candidemia in non-neutropenic patients; however, prophylactic use of fluconazole in bone-marrow transplant patients has been associated with increased recovery of C. krusei.[24147][24148]

Intermittent IV Infusion
In comparative clinical trials of fluconazole 150 mg single doses for vaginal candidiasis (n = 448), nausea (7%) and abdominal pain (6%) were among the most common treatment-related adverse reactions associated with fluconazole. Other adverse effects reported included diarrhea (3%), dyspepsia (1%), and dysgeusia (1%). In patients receiving fluconazole for 7 days or more in clinical trials for other indications (n = 4,048), the most frequently reported (1% or more of patients) adverse reactions included nausea (4%), vomiting (2%), abdominal pain (12%), and diarrhea (2%). In children receiving fluconazole in phase II/III clinical trials (n = 577), the most commonly reported adverse reactions were nausea (2%), vomiting (5%), abdominal pain (3%), and diarrhea (2%). Xerostomia has been reported with postmarketing use of fluconazole.[28674]
In patients receiving fluconazole for 7 days or more in clinical trials (n = 4,048), skin rash occurred in approximately 2% of patients. Exfoliative skin disorders, such as Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN), have been reported in patients taking fluconazole. Fluconazole-associated dermatologic adverse events have resulted in fatal outcomes for patients with serious underlying diseases, such as AIDS or malignancy. Monitor drug recipients for development of a rash. If a rash is observed in a patient being treated for a superficial fungal infection and the rash is attributed to fluconazole, immediately discontinue use of the drug. If a rash develops in a patient being treated for a deep-seated fungal infection, closely monitor the patient and discontinue fluconazole if the lesion progresses. Other dermatologic adverse reactions reported during postmarketing use of the drug include acute generalized exanthematous pustulosis (AGEP), drug reaction with eosinophilia and systemic symptoms (DRESS), and hyperhidrosis (increased sweating).[28674] Fluconazole-induced alopecia has also been reported in postmarketing surveillance. In most cases, the hair loss involved the scalp, but in other cases, substantial loss of facial, leg, axillary, pubic, or chest hair occurred. In 3 patients, scalp hair loss required the use of a wig. In almost all patients, the alopecia resolved after discontinuation or reduction in the dose of fluconazole.[24277] [28674]
Rarely, angioedema and anaphylactoid reactions (including facial edema and pruritus) have been reported with fluconazole in postmarketing experience after single and multiple doses.[28674]
Some azole antifungals, including fluconazole, have been associated with QT prolongation. During postmarketing experience, there have been very rare reports of QT prolongation and torsade de pointes (TdP) in patients taking fluconazole. These reports included seriously ill patients with multiple confounding risk factors that may have been contributory. Fluconazole is not likely to cause TdP at usual therapeutic dosages.[28225] [28674]
Fluconazole has been associated with rare cases of serious hepatotoxicity. These hepatic reactions have ranged from mild transient elevated hepatic enzymes to clinical hepatitis, cholestasis and fulminant hepatic failure, including fatalities. Instances of fatal hepatic reactions were noted to occur primarily in patients with serious underlying medical conditions (predominantly AIDS or malignancy) and often while taking multiple concomitant medications. Transient hepatic reactions, including hepatitis and jaundice, have occurred among patients with no other identifiable risk factors. Fluconazole hepatotoxicity has usually, but not always, been reversible on discontinuation of therapy. Monitor patients who develop abnormal liver function tests during fluconazole therapy for the development of more severe hepatic injury. Discontinue fluconazole if clinical signs and symptoms consistent with liver disease develop that may be attributable to fluconazole. In 2 comparative trials evaluating the efficacy of fluconazole for the suppression of relapse of cryptococcal meningitis, a statistically significant increase was observed in median aspartate aminotransferase (AST) concentrations from a baseline value of 30 International Units/L to 41 International Units/L in 1 trial and 34 International Units/L to 66 International Units/L in the other trial. The overall rate of serum transaminase elevations of more than 8 times the upper limit of normal was approximately 1% in fluconazole-treated patients in clinical trials. These elevations occurred in patients with severe underlying disease, predominantly AIDS or malignancies, most of whom were receiving multiple concomitant medications, including many known to be hepatotoxic.[28674] Elevated transaminases (alanine aminotransferase (ALT), 5%; AST, 3%) and alkaline phosphatase (2%) have been reported in pediatric patients and were the most common treatment-related laboratory abnormalities in clinical trials.[53061] A higher incidence of cholestasis (direct bilirubin 2 mg/dL or more) was reported in neonates receiving more frequent dosing of fluconazole prophylaxis compared with those receiving less frequent dosing of fluconazole prophylaxis (43% vs. 29%) in a retrospective study (n = 244).[53058]
Leukopenia, including neutropenia and agranulocytosis, and thrombocytopenia have been reported during postmarketing use of fluconazole.[28674]
In comparative clinical trials of fluconazole 150 mg single doses for vaginal candidiasis (n = 448), headache (13%) was among the most common treatment-related adverse reactions associated with fluconazole. Dizziness was reported in 1% of patients receiving fluconazole. In patients receiving fluconazole for 7 days or more in clinical trials for other indications (n = 4,048), headache was reported in 2% of patients receiving fluconazole. Seizures, drowsiness, insomnia, paresthesias, tremor, and vertigo have been reported during postmarketing use of fluconazole.[28674]
Hypokalemia, hypercholesterolemia, and hypertriglyceridemia have been reported during postmarketing use of fluconazole.[28674]
Asthenia, fatigue, fever, malaise, and myalgia have been reported during postmarketing use of fluconazole.[28674]
Reversible cases of adrenocortical insufficiency have been reported in patients receiving fluconazole. Advise patients to report any symptoms of adrenal insufficiency, including long-lasting fatigue, muscle weakness, loss of appetite, weight loss, abdominal pain, nausea, vomiting, or dizziness.[28674]
Anemia and acute renal failure have been reported in postmarketing experience. These events were observed more frequently in persons 65 years of age and older than in younger persons.[28674]
Fluconazole has been associated with teratogenesis when used early in a pregnancy at high doses. Fluconazole produces a characteristic pattern of fetal abnormalities including craniofacial, skeletal and cardiac anomalies, similar to Antley-Bixler syndrome when used during the first trimester. These effects may be dose-dependent. The nature of the observed birth defects suggests that the teratogenic effects may occur before the woman is aware she is pregnant. The exact mechanism is not known.[26025] [28674]
GI perforation, including ileal and small intestinal perforation, was reported at a higher incidence in premature neonates weighing less than 750 g receiving fluconazole prophylaxis (6 mg/kg/dose given twice-weekly for 6 weeks) compared with placebo (7% vs. 4%) in a prospective, randomized, double-blind, multicenter study (n = 361). Other serious adverse reactions reported in the fluconazole vs. placebo groups, respectively, include necrotizing enterocolitis (NEC; 14% vs. 16%), respiratory failure (7% vs. 2%), and bacterial sepsis (5% vs. 7%). The most common fatal serious adverse reactions in the fluconazole vs. placebo groups, respectively, were NEC (5% vs. 5%), neonatal bacterial sepsis (3% vs. 4%), and respiratory failure (2% vs. 0.6%).[28674]
There have been reports of cases of superinfection with Candida species other than C. albicans, which are often inherently not susceptible to fluconazole (e.g., C. krusei). Such cases may require alternative antifungal therapy.[28674] [60686]
Fluconazole should be administered cautiously in patients with potentially proarrhythmic conditions, including a history of torsade de pointes. Some azole antifungals, including fluconazole, have been associated with QT prolongation. During post-marketing surveillance, rare cases of QT prolongation and torsade de pointes have been reported with fluconazole use. These reports have included seriously ill patients with multiple confounding risk factors that may have been contributory, such as structural cardiac disease, electrolyte imbalance, and concomitant medications that could be associated with proarrhythmic conditions. Fluconazole is not likely to cause QT prolongation or torsade de pointes when administered at usual therapeutic dosages. Use fluconazole with caution in patients with conditions that may increase the risk of QT prolongation including congenital long QT syndrome, bradycardia, AV block, heart failure, stress-related cardiomyopathy, myocardial infarction, stroke, hypomagnesemia, hypokalemia, hypocalcemia, or in patients receiving medications known to prolong the QT interval or cause electrolyte imbalances. Females, people 65 years and older, patients with sleep deprivation, pheochromocytoma, sickle cell disease, hypothyroidism, hyperparathyroidism, hypothermia, systemic inflammation (e.g., human immunodeficiency virus (HIV) infection, fever, and some autoimmune diseases including rheumatoid arthritis, systemic lupus erythematosus (SLE), and celiac disease) and patients undergoing apheresis procedures (e.g., plasmapheresis [plasma exchange], cytapheresis) may also be at increased risk for QT prolongation.[28225] [28674] [28432] [28457] [56592] [65180]
Use fluconazole with caution in patients with azole antifungals hypersensitivity. Fluconazole may have a cross sensitivity with other azole derivatives.[28674] [60686]
Use caution in patients with hepatic disease as fluconazole has been associated with rare cases of severe hepatotoxicity, including fatalities. Hepatotoxicity has generally been reversible, but not always, with therapy discontinuation. Monitor patients who develop abnormal liver function tests during therapy for the development of more severe hepatic injury. If signs and symptoms of hepatotoxicity develop, discontinue fluconazole therapy.[28674] [60686]
Use caution in patients with renal impairment or renal failure as fluconazole is primarily excreted renally. Dose adjustments are recommended in patients with renal impairment.[28674] [60686]
Fluconazole may rarely cause dizziness or seizures. Advise patients to use caution when driving or operating machinery until they are aware of the effects of the drug.[28674] [60686]
Since fluconazole is primarily cleared renally and older adults are more likely to have decreased renal function, care should be taken to adjust dose based on creatinine clearance. It may also be useful to monitor renal function. Systemic fluconazole can prolong the QT interval. Geriatric adults may be at increased risk for QT prolongation and for serious drug-drug interactions that may increase the risk QT prolongation risk or may increase the risk for other serious side effects.[28432] [28457] [56592] [65180] [28674]
Serious rash, including exfoliative skin disorders such as Stevens-Johnson syndrome and toxic epidermal necrolysis, has been reported in patients receiving treatment with fluconazole. Fluconazole-associated dermatologic adverse reactions have resulted in fatal outcomes for patients with serious underlying diseases. Monitor drug recipients for development of rash. If a rash is observed on a patient being treated for a superficial fungal infection, and the rash is attributed to fluconazole, discontinue use of the drug. However, if a rash develops on a patient being treated for a deep-seated fungal infection, monitor the patient closely and discontinue the drug if the lesion progresses.[28674] [60686]
In patients with hereditary fructose intolerance, glucose/galactose malabsorption, or sucrase-isomaltase deficiency, use of fluconazole oral suspension is not recommended due to the sucrose content.[28674]
Avoid the use of fluconazole during pregnancy except in patients with severe or potentially life-threatening fungal infections in whom fluconazole may be used if the potential benefit outweighs the possible risk to the fetus. No adequate and well-controlled studies have been conducted in human pregnancy; however, a few case reports have described a pattern of distinct congenital anomalies in infants exposed in utero to high dose maternal fluconazole (400 to 800 mg/day) during most or all of the first trimester; these effects are similar to those observed in animal studies.[28674] The features observed in fluconazole-exposed infants included brachycephaly, abnormal facies, abnormal calvarial development, cleft palate, femoral bowing, thin ribs and long bones, arthrogryposis, and congenital heart disease. The nature of these birth defects suggests that the teratogenic effect may occur early in the first trimester.[26025] Additionally, retrospective epidemiological studies suggest a potential association between the use of low-dose fluconazole (i.e., 150 mg) and increased risk of birth defects and spontaneous abortions.[60495] [60789] Data from the National Birth Defects Prevention Study found an association between maternal exposure to low-dose fluconazole in the first trimester and both cleft lip with cleft palate and d-transposition of the great arteries. Of the 43,247 mothers analyzed, 44 case mothers and 6 control mothers were identified. The majority of cases (n = 36/50; 72%) reported taking fluconazole for vaginal candidiasis and almost all (n = 49/50) reported taking fluconazole for a short duration. Six exposed infants had cleft lip with cleft palate, 4 had an atrial septal defect, and each of the following defects had 3 exposed cases: hypospadias, tetralogy of Fallot, d-transposition of the great arteries, and pulmonary valve stenosis. Fluconazole use was associated with a significant risk for cleft lip with cleft palate (OR 5.53; 95% CI, 1.68 to 18.24) and d-transposition of the great arteries (OR 7.56; 95% CI, 1.22 to 35.45). The increases for the other conditions were not statistically significant.[60789] A large population-based cohort study of U.S. Medicaid data found oral fluconazole use during the first trimester to be associated with musculoskeletal malformations but not with oral clefts or conotruncal malformations. This cohort included 1,969,954 pregnancies, with 37,650 pregnancies exposed to oral fluconazole and 82,090 exposed to topical azoles during the first trimester. The unadjusted relative risk for musculoskeletal malformations with fluconazole vs. unexposed pregnancies was 1.37 (95% CI, 1.19 to 1.58). When comparing oral fluconazole with topical azoles, the unadjusted relative risk for musculoskeletal malformations was 1.4 (95% CI, 1.17 to 1.67). A subanalysis found a 30% increase in risk for musculoskeletal malformations for cumulative fluconazole doses of 150 to 450 mg and an almost 2-fold increase in risk for cumulative doses more than 450 mg. Malformations were defined as deformities of the skull/face/jaw, feet, and/or spine.[65469] A nationwide Danish cohort study also found an association between maternal exposure to oral fluconazole, including doses used to treat vaginal candidiasis, during gestational weeks 7 through 22 and spontaneous abortions. Specifically, 147 spontaneous abortions were reported among 3,315 fluconazole-exposed pregnancies, as compared to 563 spontaneous abortions among the 13,246 unexposed matched control pregnancies. Of these 147 spontaneous abortions, 132 were reported in pregnancies exposed to a fluconazole dose of 150 to 300 mg (n = 2,986 fluconazole-treated persons). These data indicate a statistically significant increase in risk for spontaneous abortion with maternal exposure to fluconazole during gestational weeks 7 through 22 (HR, 1.48; 95% CI, 1.23 to 1.77).[60495] Topical antifungals, administered for a longer duration in persistent or recurrent infections, are recommended for the treatment of vaginal candidiasis during pregnancy.[60741] Guidelines for the prevention of opportunistic infections in persons living with HIV recommend that oral azole antifungals, including fluconazole, not be started during pregnancy and that these agents should be discontinued in persons who become pregnant.[34362] If fluconazole is administered during pregnancy, or if a patient becomes pregnant while taking fluconazole, advise the patient of the potential hazard to the infant.[28674]
Counsel females of childbearing potential who are receiving high dose fluconazole (i.e., 400 to 800 mg/day) about the reproductive risk and contraception requirements during treatment. Advise these patients to use effective contraception during treatment and for approximately 1 week (5 to 6 half-lives) after the final dose.[28674] [60686]
Use caution when fluconazole is administered during breast-feeding.[28674] Previous American Academy of Pediatrics (AAP) recommendations considered fluconazole as usually compatible with breast-feeding.[27500] Fluconazole is distributed in human breast milk at concentrations similar to those in the plasma. A case report found breast milk to plasma ratios of 0.46, 0.85, 0.85, and 0.83 at 2, 5, 24, and 48 hours after a single 150 mg dose of fluconazole.[46093] Experts have estimated, based on limited data of concentrations in breast milk, that an exclusively breast-fed child whose mother was receiving fluconazole 200 mg daily would receive a maximum dose of 0.6 mg/kg/day. This is equivalent to 60% of the recommended dose for thrush in newborns younger than 2 weeks of age and 20% of the recommended dose for older newborns and infants.[46094] Another study determined the daily infant fluconazole dose from breast milk (assuming mean milk consumption of 150 mL/kg/day) based on the mean peak milk concentration (2.61 mcg/mL [range: 1.57 to 3.65 mcg/mL] at 5.2 hours post-dose) to be 0.39 mg/kg/day, which is approximately 13% of the recommended pediatric dose for oropharyngeal candidiasis.[28674] Fluconazole has been used successfully to treat mastitis due to yeast resistant to other therapies in breast-feeding persons.[46095] [46096]
Fluconazole is a fungistatic antifungal agent with concentration-independent activity.[53056] Like other azole antifungals, fluconazole exerts its effect by altering the fungal cell membrane. Fluconazole inhibits ergosterol synthesis by interacting with 14-alpha demethylase, a cytochrome P450 enzyme that is needed to convert lanosterol to ergosterol, an essential component of the membrane. Inhibition of ergosterol synthesis results in increased cellular permeability causing leakage of cellular contents. Fluconazole does not appear to have the same activity on human cholesterol synthesis. Other antifungal effects of azole compounds have been proposed and include inhibition of endogenous respiration, interaction with membrane phospholipids, and inhibition of the transformation of yeasts to mycelial forms. Other mechanisms may involve inhibition of purine uptake and impairment of triglyceride and/or phospholipid biosynthesis.[23613][23649]
The Clinical and Laboratory Standards Institute (CLSI) defines minimum inhibitory concentrations (MICs) for C. albicans, C. parapsilosis, and C. tropicalis as susceptible at 2 mcg/mL or less, susceptible dose-dependent (SDD) at 4 mcg/mL, and resistant at 8 mcg/mL or more. For C. glabrata, isolates are defined as SDD at 32 mcg/mL or less and resistant at 64 mcg/mL or more. C. krusei is considered intrinsically resistant to fluconazole.[28674][60487][69089]
The emergence of fungal organisms resistant to fluconazole, especially Candida species, is problematic. Increased frequency of non-Candida albicans species as causes of fungemia has been correlated in epidemiologic studies with the increased use of fluconazole both for prophylaxis and treatment. These non-Candida albicans species are often more resistant to fluconazole. Data indicate the annual incidence of fluconazole-resistant oropharyngeal candidiasis in persons with AIDS is roughly 5%. Consider susceptibility testing of invasive C. albicans isolates for persons with persistent candidemia or progressive disseminated candidiasis, despite fluconazole therapy, and on non-Candidaalbicans isolates (e.g., C. glabrata, C. tropicalis, or C. parapsilosis) from persons with candidemia or invasive disease.[26488]
Revision Date: 12/16/2024, 10:20:00 AMFluconazole is administered orally and intravenously. The pharmacokinetics of both IV and oral fluconazole are similar. Peak serum concentrations and AUC increase in proportion to the dose. Steady-state fluconazole plasma concentrations are achieved within 5 to 10 days at doses within the adult dosage range of 50 to 400 mg/day, and within 2 days when a loading dose of twice the usual daily dosage is given on the first day of therapy. Fluconazole is widely distributed into body tissues and fluids; the apparent volume of distribution approximates that of total body water. Saliva, sputum, nail, blister, and vaginal tissue concentrations are approximately equal to plasma concentrations. Urine and skin concentrations are approximately 10 times that of plasma concentrations. Fluconazole distributes well into the CSF, and achieves CSF concentrations that are 50% to 90% of plasma concentrations, regardless of the degree of meningeal inflammation. Plasma protein binding is low and ranges from 11% to 12%. Fluconazole does not appear to undergo first-pass metabolism. Elimination is mainly renal; about 65% to 80% of a dose is excreted in the urine unchanged and 11% as metabolites. A clearance of approximately 0.23 mL/kg/minute has been reported for adults. Small amounts of fluconazole are excreted in the feces. Plasma elimination half-life in adults with normal renal function is approximately 30 hours (range: 20 to 50 hours).[28674][52683][53005]
Affected cytochrome P450 isoenzymes and drug transporters: CYP2C9, CYP2C19, CYP3A4, UGT2B7
Fluconazole potently inhibits CYP2C19 and moderately inhibits CYP2C9 and CYP3A4. The extent of CYP3A4 inhibition is less than with ketoconazole or itraconazole.[28674][29036][34447] In vitro studies have also shown fluconazole to be a concentration-dependent inhibitor of uridine diphosphoglucuronosyltransferase UGT2B7.[60255][60256]
Fluconazole is well absorbed after oral administration with a bioavailability of approximately 90%. Peak concentrations are reached approximately 1 to 2 hours after administration. Food does not affect the absorption. Bioequivalence has been established between the suspension and tablet formulations.[28674]
Peak concentrations are reached approximately 1 to 2 hours after administration.[60686]
Fluconazole clearance is significantly reduced in patients with renal impairment. A 3-hour hemodialysis session reduces plasma concentrations by approximately 50%.[28674] In a study in 17 children with renal impairment, the elimination half-life of fluconazole was approximately 72 hours in patients requiring peritoneal dialysis (PD) compared with approximately 31 hours in children in the non-PD group (mild renal impairment; mean CrCl 26 mL/minute/1.73 m2).[53009]
Infants, Children, and Adolescents 3 months to 17 years
The clearance of fluconazole is greater in pediatric patients compared to adults. A clearance and elimination half-life of approximately 0.4 to 0.66 mL/kg/minute and 15 to 25 hours, respectively, have been reported in pediatric patients 9 months and older.[28674] Volume of distribution is also greater in children compared with adults. A mean volume of distribution of 0.95 L/kg and 0.7 L/kg has been reported for children and adolescents, respectively. The value in adolescents is similar to what has been reported in adults.[28674][53005][53007][53011]
Neonates and Infants 1 to 2 months
Clearance of fluconazole is prolonged in neonates and young infants compared with children and adults and increases with postnatal age (PNA). In a pharmacokinetic study in premature neonates (gestational age (GA) 26 to 29 weeks), mean total clearance corrected for weight was 0.18 mL/minute/kg (n = 7), 0.33 mL/minute/kg (n = 7), and 0.52 mL/minute/kg (n = 4) at postnatal ages 1 day, 7 days, and 13 days, respectively. Corresponding mean elimination half-lives were 88.6 hours, 67.5 hours, and 55.2 hours, respectively.[32700] In another study in 8 neonates and young infants (GA 35 to 38 weeks; PNA 6 to 59 days), the mean clearance and elimination half-life were 0.29 mL/minute/kg and 54.2 hours, respectively.[28674][53037] Volume of distribution of fluconazole is also greatest in the neonatal period, with values of approximately 1 to 2.25 L/kg reported.[32700][53007][53010][53037] Because of the large volume of distribution and slow elimination, the use of a loading dose on day 1 of therapy is recommended to achieve therapeutic serum concentrations faster. In a study of 13 premature and term patients (median GA of 37 weeks, range: 24 to 39 weeks; median PNA 19 days, range: 5 to 262 days), of the 12 patients who received a 25 mg/kg loading dose, 9 patients achieved an AUC0-24 of more than 400 mg x hour/L in the first 24 hours. A population pharmacokinetic model using data from 55 pediatric patients (GA 23 to 40 weeks, PNA 1 to 88 days) found that a loading dose of 25 mg/kg is necessary to reach target AUC more than 400 mg x hour/L within 24 hours of initiating therapy in patients younger than 3 months.[28674] Additionally, data from a population pharmacokinetic study using Monte Carlo simulations of premature and term neonates revealed that a dose of at least 12 mg/kg/day is necessary to achieve target exposure (AUC/MIC of 50 or more for Candida species with an MIC of 8 mcg/mL or less) in 90% of neonates younger than 30 weeks gestation and 80% of neonates 30 to 40 weeks gestation.[53038] A maintenance dose of 9 mg/kg once daily is recommended in neonates younger than 30 weeks GA and 12 mg/kg once daily is recommended in neonates 30 weeks GA and older.[28674]
Pediatric Patients Receiving Extracorporeal Membrane Oxygenation (ECMO)
A population PK model using data from 21 pediatric patients ages from birth to 17 years supported with ECMO and 19 pediatric non-ECMO patients ages from birth to 2 years found that clearance was related to serum creatinine, while a higher volume of distribution was related to presence of ECMO support. The median volume of distribution was 1.3 L/kg in pediatric patients on ECMO and 0.9 L/kg in those not on ECMO. Simulations suggested that a loading dose of 35 mg/kg is needed to achieve the target AUC0-24 more than 400 mg x hour/L within the first 24 hours in pediatric patients on ECMO.[28674]
Elimination of fluconazole can be impaired in older adults due to expected decrease in renal function. In older adult patients receiving single 50 mg PO doses of fluconazole, the Cmax and AUC of fluconazole were higher than those reported in normal young male volunteers; the mean terminal half-life was 46.2 hours in older adults vs. 30 hours in younger patients. Coadministration with diuretics did not significantly alter the AUC or Cmax of fluconazole. Older adult patients had lower creatinine clearance, lower percentage of drug recovered in urine, and lower fluconazole renal clearance estimates compared to younger volunteers.[28674]
Avoid the use of fluconazole during pregnancy except in patients with severe or potentially life-threatening fungal infections in whom fluconazole may be used if the potential benefit outweighs the possible risk to the fetus. No adequate and well-controlled studies have been conducted in human pregnancy; however, a few case reports have described a pattern of distinct congenital anomalies in infants exposed in utero to high dose maternal fluconazole (400 to 800 mg/day) during most or all of the first trimester; these effects are similar to those observed in animal studies.[28674] The features observed in fluconazole-exposed infants included brachycephaly, abnormal facies, abnormal calvarial development, cleft palate, femoral bowing, thin ribs and long bones, arthrogryposis, and congenital heart disease. The nature of these birth defects suggests that the teratogenic effect may occur early in the first trimester.[26025] Additionally, retrospective epidemiological studies suggest a potential association between the use of low-dose fluconazole (i.e., 150 mg) and increased risk of birth defects and spontaneous abortions.[60495] [60789] Data from the National Birth Defects Prevention Study found an association between maternal exposure to low-dose fluconazole in the first trimester and both cleft lip with cleft palate and d-transposition of the great arteries. Of the 43,247 mothers analyzed, 44 case mothers and 6 control mothers were identified. The majority of cases (n = 36/50; 72%) reported taking fluconazole for vaginal candidiasis and almost all (n = 49/50) reported taking fluconazole for a short duration. Six exposed infants had cleft lip with cleft palate, 4 had an atrial septal defect, and each of the following defects had 3 exposed cases: hypospadias, tetralogy of Fallot, d-transposition of the great arteries, and pulmonary valve stenosis. Fluconazole use was associated with a significant risk for cleft lip with cleft palate (OR 5.53; 95% CI, 1.68 to 18.24) and d-transposition of the great arteries (OR 7.56; 95% CI, 1.22 to 35.45). The increases for the other conditions were not statistically significant.[60789] A large population-based cohort study of U.S. Medicaid data found oral fluconazole use during the first trimester to be associated with musculoskeletal malformations but not with oral clefts or conotruncal malformations. This cohort included 1,969,954 pregnancies, with 37,650 pregnancies exposed to oral fluconazole and 82,090 exposed to topical azoles during the first trimester. The unadjusted relative risk for musculoskeletal malformations with fluconazole vs. unexposed pregnancies was 1.37 (95% CI, 1.19 to 1.58). When comparing oral fluconazole with topical azoles, the unadjusted relative risk for musculoskeletal malformations was 1.4 (95% CI, 1.17 to 1.67). A subanalysis found a 30% increase in risk for musculoskeletal malformations for cumulative fluconazole doses of 150 to 450 mg and an almost 2-fold increase in risk for cumulative doses more than 450 mg. Malformations were defined as deformities of the skull/face/jaw, feet, and/or spine.[65469] A nationwide Danish cohort study also found an association between maternal exposure to oral fluconazole, including doses used to treat vaginal candidiasis, during gestational weeks 7 through 22 and spontaneous abortions. Specifically, 147 spontaneous abortions were reported among 3,315 fluconazole-exposed pregnancies, as compared to 563 spontaneous abortions among the 13,246 unexposed matched control pregnancies. Of these 147 spontaneous abortions, 132 were reported in pregnancies exposed to a fluconazole dose of 150 to 300 mg (n = 2,986 fluconazole-treated persons). These data indicate a statistically significant increase in risk for spontaneous abortion with maternal exposure to fluconazole during gestational weeks 7 through 22 (HR, 1.48; 95% CI, 1.23 to 1.77).[60495] Topical antifungals, administered for a longer duration in persistent or recurrent infections, are recommended for the treatment of vaginal candidiasis during pregnancy.[60741] Guidelines for the prevention of opportunistic infections in persons living with HIV recommend that oral azole antifungals, including fluconazole, not be started during pregnancy and that these agents should be discontinued in persons who become pregnant.[34362] If fluconazole is administered during pregnancy, or if a patient becomes pregnant while taking fluconazole, advise the patient of the potential hazard to the infant.[28674]
Use caution when fluconazole is administered during breast-feeding.[28674] Previous American Academy of Pediatrics (AAP) recommendations considered fluconazole as usually compatible with breast-feeding.[27500] Fluconazole is distributed in human breast milk at concentrations similar to those in the plasma. A case report found breast milk to plasma ratios of 0.46, 0.85, 0.85, and 0.83 at 2, 5, 24, and 48 hours after a single 150 mg dose of fluconazole.[46093] Experts have estimated, based on limited data of concentrations in breast milk, that an exclusively breast-fed child whose mother was receiving fluconazole 200 mg daily would receive a maximum dose of 0.6 mg/kg/day. This is equivalent to 60% of the recommended dose for thrush in newborns younger than 2 weeks of age and 20% of the recommended dose for older newborns and infants.[46094] Another study determined the daily infant fluconazole dose from breast milk (assuming mean milk consumption of 150 mL/kg/day) based on the mean peak milk concentration (2.61 mcg/mL [range: 1.57 to 3.65 mcg/mL] at 5.2 hours post-dose) to be 0.39 mg/kg/day, which is approximately 13% of the recommended pediatric dose for oropharyngeal candidiasis.[28674] Fluconazole has been used successfully to treat mastitis due to yeast resistant to other therapies in breast-feeding persons.[46095] [46096]
