Clinical
Posaconazole injection is used to prevent serious fungal infections that can spread throughout the body in adults and children 2 years of age and older with a weakened ability to fight infection. Posaconazole injection is also used to treat invasive aspergillosis (a serious fungal infection that begins in the lungs and spreads through the bloodstream to other organs) in adults and teenagers 13 years of age and older. Posaconazole injection is in a class of medications called azole antifungals. It works by slowing the growth of fungi that cause infection.

⛔ Contraindications ▾
4 CONTRAINDICATIONS Known hypersensitivity to posaconazole or other azole antifungal agents. ( 4.1 ) Coadministration of posaconazole with the following drugs is contraindicated; posaconazole increases concentrations and toxicities of: Sirolimus ( 4.2 , 5.1 , 7.1 ) CYP3A4 substrates (pimozide, quinidine): can result in QTc interval prolongation and cases of torsades de pointes (TdP) ( 4.3 , 5.2 , 7.2 ) HMG-CoA Reductase Inhibitors Primarily Metabolized through CYP3A4 ( 4.4 , 7.3 ) Ergot alkaloids ( 4.5 , 7.4 ) Venetoclax: In patients with chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL) at initiation and during the ramp-up phase ( 4.6 , 5.11 , 7.16 )
4.1Hypersensitivity Posaconazole is contraindicated in persons with known hypersensitivity to posaconazole or other azole antifungal agents.
4.2Use with Sirolimus Posaconazole is contraindicated with sirolimus. Concomitant administration of posaconazole with sirolimus increases the sirolimus blood concentrations by approximately 9-fold and can result in sirolimus toxicity [see Drug Interactions (7.1) and Clinical Pharmacology (12.3) ] .
4.3QT Prolongation with Concomitant Use with CYP3A4 Substrates Posaconazole is contraindicated with CYP3A4 substrates that prolong the QT interval. Concomitant administration of posaconazole with the CYP3A4 substrates, pimozide and quinidine may result in increased plasma concentrations of these drugs, leading to QTc prolongation and cases of torsades de pointes [see Warnings and Precautions (5.2) and Drug Interactions (7.2) ] .
4.4HMG-CoA Reductase Inhibitors Primarily Metabolized Through CYP3A4 Coadministration with the HMG-CoA reductase inhibitors that are primarily metabolized through CYP3A4 (e.g., atorvastatin, lovastatin, and simvastatin) is contraindicated since increased plasma concentration of these drugs can lead to rhabdomyolysis [see Drug Interactions (7.3) and Clinical Pharmacology (12.3) ] .
4.5Use with Ergot Alkaloids Posaconazole may increase the plasma concentrations of ergot alkaloids (ergotamine and dihydroergotamine) which may lead to ergotism [see Drug Interactions (7.4) ] .
4.6Use with Venetoclax Coadministration of posaconazole with venetoclax at initiation and during the ramp-up phase is contraindicated in patients with chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL) due to the potential for increased risk of tumor lysis syndrome [see Warnings and Precautions (5.11) and Drug Interactions (7.16) ].
⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS Calcineurin-Inhibitor Toxicity : Posaconazole increases concentrations of cyclosporine or tacrolimus; reduce dose of cyclosporine and tacrolimus and monitor concentrations frequently. ( 5.1 ) Arrhythmias and QTc Prolongation : Posaconazole has been shown to prolong the QTc interval and cause cases of TdP. Administer with caution to patients with potentially proarrhythmic conditions.
Do not administer with drugs known to prolong QTc interval and metabolized through CYP3A4. ( 5.2 ) Electrolyte Disturbances : Monitor and correct, especially those involving potassium (K + ), magnesium (Mg ++ ), and calcium (Ca ++ ), before and during posaconazole therapy. ( 5.3 ) Pseudoaldosteronism : Manifested by the onset or worsening of hypertension, and abnormal laboratory findings.
Monitor blood pressure and potassium levels, and manage as necessary. ( 5.4 ) Hepatic Toxicity : Elevations in liver tests may occur. Discontinuation should be considered in patients who develop abnormal liver tests or monitor liver tests during treatment.
( 5.5 ) Renal Impairment : Posaconazole injection should be avoided in patients with moderate or severe renal impairment (creatinine clearance <50 mL/min), unless an assessment of the benefit/risk to the patient justifies the use of posaconazole injection. ( 5.6 , 8.6 ) Concomitant Use with Midazolam : Posaconazole can prolong hypnotic/sedative effects. Monitor patients and benzodiazepine receptor antagonists should be available.
( 5.7 , 7.5 ) Vincristine Toxicity : Concomitant administration of azole antifungals, including posaconazole, with vincristine has been associated with neurotoxicity and other serious adverse reactions; reserve azole antifungals, including posaconazole, for patients receiving a vinca alkaloid, including vincristine, who have no alternative antifungal treatment options. ( 5.8 , 7.10 ) Venetoclax Toxicity: Concomitant administration of posaconazole with venetoclax may increase venetoclax toxicities, including the risk of tumor lysis syndrome, neutropenia, and serious infections; monitor for toxicity and reduce venetoclax dose.
( 4.6 , 5.11 , 7.16 )
5.1Calcineurin-Inhibitor Toxicity Concomitant administration of posaconazole with cyclosporine or tacrolimus increases the whole blood trough concentrations of these calcineurin-inhibitors [see Drug Interactions (7.1) and Clinical Pharmacology (12.3) ] . Nephrotoxicity and leukoencephalopathy (including deaths) have been reported in clinical efficacy studies in patients with elevated cyclosporine or tacrolimus concentrations. Frequent monitoring of tacrolimus or cyclosporine whole blood trough concentrations should be performed during and at discontinuation of posaconazole treatment and the tacrolimus or cyclosporine dose adjusted accordingly.
5.2Arrhythmias and QT Prolongation Some azoles, including posaconazole, have been associated with prolongation of the QT interval on the electrocardiogram. In addition, cases of torsades de pointes have been reported in patients taking posaconazole. Results from a multiple time-matched ECG analysis in healthy volunteers did not show any increase in the mean of the QTc interval.
Multiple, time-matched ECGs collected over a 12-hour period were recorded at baseline and steady-state from 173 healthy male and female volunteers (18-85 years of age) administered NOXAFIL Oral Suspension 400 mg twice daily with a high-fat meal. In this pooled analysis, the mean QTc (Fridericia) interval change from baseline was –5 msec following administration of the recommended clinical dose. A decrease in the QTc(F) interval (–3 msec) was also observed in a small number of subjects (n=16) administered placebo.
The placebo-adjusted mean maximum QTc(F) interval change from baseline was <0 msec (–8 msec). No healthy subject administered posaconazole had a QTc(F) interval ≥500 msec or an increase ≥60 msec in their QTc(F) interval from baseline. Posaconazole should be administered with caution to patients…
🤒 Adverse Reactions ▾
6 ADVERSE REACTIONS The following serious and otherwise important adverse reactions are discussed in detail in another section of the labeling: Hypersensitivity [see Contraindications (4.1) ] Arrhythmias and QT Prolongation [see Warnings and Precautions (5.2) ] Hepatic Toxicity [see Warnings and Precautions (5.5) ] Adult Patients : Common adverse reactions in studies with posaconazole in adults are diarrhea, nausea, fever, vomiting, headache, coughing, and hypokalemia. ( 6.1 ) Pediatric Patients: Common adverse reactions (incidence >20% receiving 6 mg/kg posaconazole injection) in a study in pediatric patients are pyrexia, febrile neutropenia, vomiting, mucosal inflammation, pruritus, hypertension, hypokalemia, and stomatitis.
( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Par Health at 1-800-828-9393 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch .
6.1Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in clinical trials of posaconazole cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. Clinical Trial Experience in Adults Clinical Trial Experience with Posaconazole Injection and NOXAFIL Delayed-Release Tablets for the Treatment of Invasive Aspergillosis The safety of posaconazole injection and NOXAFIL delayed-release tablet was assessed in a randomized, double-blind, active-controlled clinical study of posaconazole injection and NOXAFIL delayed-release tablets versus voriconazole for treatment of invasive aspergillosis (Aspergillosis Treatment Study).
A total of 575 (288 in posaconazole arm, 287 in voriconazole arm) adult and pediatric patients 13 years of age and older with proven, probable or possible invasive aspergillosis were included. The median duration of treatment was 67 days for posaconazole injection or NOXAFIL delayed-release tablet and 64 days for voriconazole, with 55% to 60% of subjects starting treatment with the IV formulation of either drug. The median duration of the first instance of IV treatment (before switching to oral treatment or discontinuing or completing study treatment) was 9 days for both groups.
Table 7 presents adverse reactions reported at an incidence of ≥ 10% in either one of the groups in Aspergillosis Treatment Study. Adverse reactions leading to treatment discontinuation were reported for 33.9% of subjects. The most commonly reported adverse reactions (>2% of subjects) leading to treatment discontinuation were septic shock, respiratory failure, and bronchopulmonary aspergillosis in the posaconazole arm, and septic shock and acute myeloid leukemia in the voriconazole arm.

🔄 Drug Interactions ▾
7 DRUG INTERACTIONS Posaconazole is primarily metabolized via UDP glucuronosyltransferase and is a substrate of p- glycoprotein (P-gp) efflux. Therefore, inhibitors or inducers of these clearance pathways may affect posaconazole plasma concentrations. Coadministration of drugs that can decrease the plasma concentrations of posaconazole should generally be avoided unless the benefit outweighs the risk.
If such drugs are necessary, patients should be monitored closely for breakthrough fungal infections. Posaconazole is also a strong inhibitor of CYP3A4. Therefore, plasma concentrations of drugs predominantly metabolized by CYP3A4 may be increased by posaconazole [see Clinical Pharmacology (12.3) ] .
The following information was derived from data with NOXAFIL Oral Suspension or early tablet formulation unless otherwise noted. All drug interactions with NOXAFIL Oral Suspension, except for those that affect the absorption of posaconazole (via gastric pH and motility), are considered relevant to posaconazole injection as well. Interaction Drug Interaction Rifabutin, phenytoin, efavirenz Avoid coadministration unless the benefit outweighs the risks ( 7.6 , 7.7 , 7.8 ) Other drugs metabolized by CYP3A4 Consider dosage adjustment and monitor for adverse effects and toxicity ( 7.1 , 7.10 , 7.11 ) Digoxin Monitor digoxin plasma concentrations ( 7.12 ) Fosamprenavir Monitor for breakthrough fungal infections ( 7.6 )
7.1Immunosuppressants Metabolized by CYP3A4 Sirolimus: Concomitant administration of posaconazole with sirolimus increases the sirolimus blood concentrations by approximately 9-fold and can result in sirolimus toxicity. Therefore, posaconazole is contraindicated with sirolimus [see Contraindications (4.2) and Clinical Pharmacology (12.3) ] . Tacrolimus: Posaconazole has been shown to significantly increase the C max and AUC of tacrolimus.
At initiation of posaconazole treatment, reduce the tacrolimus dose to approximately one-third of the original dose. Frequent monitoring of tacrolimus whole blood trough concentrations should be performed during and at discontinuation of posaconazole treatment and the tacrolimus dose adjusted accordingly [see Warnings and Precautions (5.1) and Clinical Pharmacology (12.3) ] . Cyclosporine: Posaconazole has been shown to increase cyclosporine whole blood concentrations in heart transplant patients upon initiation of posaconazole treatment.
It is recommended to reduce cyclosporine dose to approximately three-fourths of the original dose upon initiation of posaconazole treatment. Frequent monitoring of cyclosporine whole blood trough concentrations should be performed during and at discontinuation of posaconazole treatment and the cyclosporine dose adjusted accordingly [see Warnings and Precautions (5.1) and Clinical Pharmacology (12.3) ] .
7.2CYP3A4 Substrates Concomitant administration of posaconazole with CYP3A4 substrates such as pimozide and quinidine may result in increased plasma concentrations of these drugs, leading to QTc prolongation and cases of torsades de pointes. Therefore, posaconazole is contraindicated with these drugs [see Contraindications (4.3) and Warnings and Precautions (5.2) ] .
7.3HMG-CoA Reductase Inhibitors (Statins) Primarily Metabolized Through CYP3A4 Concomitant administration of posaconazole with simvastatin increases the simvastatin plasma concentrations by approximately 10-fold. Therefore, posaconazole is contraindicated with HMG-CoA reductase inhibitors primarily metabolized through CYP3A4 [see Contraindications (4.4) and Clinical Pharmacology (12.3) ] .
7.4Ergot Alkaloids Most of the ergot alkaloids are substrates of CYP3A4. Posaconazole may increase the plasma concentrations of ergot alkaloids (ergotamine and dihydroergotamine) which may lead to ergotism. Therefore, posaconazole is contraindicated with ergot alkaloids [see Contraindications (4.5) ] .
7.5Benzodiazepines Metabolized by CYP3A4 Concomitant administration of posaconazole with midazolam incre…
👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS Pregnancy : Based on animal data, may cause fetal harm. ( 8.1 ) Pediatrics : Safety and effectiveness in patients younger than 2 years of age have not been established. ( 8.4 ) Severe Renal Impairment : Monitor closely for breakthrough fungal infections. ( 8.6 )
8.1Pregnancy Risk Summary Based on findings from animal data, posaconazole may cause fetal harm when administered to pregnant women. Available data for use of posaconazole in pregnant women are insufficient to establish a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes. In animal reproduction studies, skeletal malformations (cranial malformations and missing ribs) and maternal toxicity (reduced food consumption and reduced body weight gain) were observed when posaconazole was dosed orally to pregnant rats during organogenesis at doses ≥1.4 times the 400 mg twice daily oral suspension regimen based on steady-state plasma concentrations of posaconazole in healthy volunteers.
In pregnant rabbits dosed orally during organogenesis, increased resorptions, reduced litter size, and reduced body weight gain of females were seen at doses 5 times the exposure achieved with the 400 mg twice daily oral suspension regimen. Doses of ≥ 3 times the clinical exposure caused an increase in resorptions in these rabbits (see Data) . Based on animal data, advise pregnant women of the potential risk to a fetus.
The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively.
Data Animal Data Posaconazole resulted in maternal toxicity (reduced food consumption and reduced body weight gain) and skeletal malformations (cranial malformations and missing ribs) when given orally to pregnant rats during organogenesis (Gestational Days 6 through 15) at doses ≥27 mg/kg (≥1.4 times the 400 mg twice daily oral suspension regimen based on steady-state plasma concentrations of drug in healthy volunteers). The no-effect dose for malformations and maternal toxicity in rats was 9 mg/kg, which is 0.7 times the exposure achieved with the 400 mg twice daily oral suspension regimen.
No malformations were seen in rabbits dosed during organogenesis (Gestational Days 7 through 19) at doses up to 80 mg/kg (5 times the exposure achieved with the 400 mg twice daily oral suspension regimen). In the rabbit, the no-effect dose was 20 mg/kg, while high doses of 40 mg/kg and 80 mg/kg (3 or 5 times the clinical exposure) caused an increase in resorptions. In rabbits dosed at 80 mg/kg, a reduction in body weight gain of females and a reduction in litter size were seen.
8.2Lactation Risk Summary There are no data on the presence of posaconazole in human milk, the effects on the breastfed infant, or the effects on milk production. Posaconazole is excreted in the milk of lactating rats. When a drug is present in animal milk, it is likely that the drug will be present in human milk.
The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for posaconazole and any potential adverse effects on the breastfed child from posaconazole or from the underlying maternal condition.
8.4Pediatric Use The safety and effectiveness of posaconazole injection for the prophylaxis of invasive Aspergillus and Candida infections have been established in pediatric patients aged 2 and older who are at high risk of developing these infections due to being severely immunocompromised, such as HSCT recipients with GVHD or those with hematologic malignancies with prolonged neutropenia from chemotherapy. The safety and effectiveness of posaconazole injection for the treatment of invasive aspergillosis have been esta…

🧒 Pediatric Use ▾
8.4Pediatric Use The safety and effectiveness of posaconazole injection for the prophylaxis of invasive Aspergillus and Candida infections have been established in pediatric patients aged 2 and older who are at high risk of developing these infections due to being severely immunocompromised, such as HSCT recipients with GVHD or those with hematologic malignancies with prolonged neutropenia from chemotherapy. The safety and effectiveness of posaconazole injection for the treatment of invasive aspergillosis have been established in pediatric patients aged 13 years and older.
Use of posaconazole in these age groups is supported by evidence from adequate and well-controlled studies of posaconazole in adult and pediatric patients and additional pharmacokinetic and safety data in pediatric patients 2 years of age and older [see Adverse Reactions ( 6.1 ), Clinical Pharmacology ( 12.3 ) and Clinical Studies ( 14 )]. The safety and effectiveness of posaconazole have not been established in pediatric patients younger than 2 years of age.
🧓 Geriatric Use ▾
8.5Geriatric Use No overall differences in the safety of posaconazole injection was observed between geriatric patients and younger adult patients in the clinical trials; therefore, no dosage adjustment is recommended for any formulation of posaconazole in geriatric patients. No clinically meaningful differences in the pharmacokinetics of posaconazole were observed in geriatric patients compared to younger adult patients during clinical trials [see Clinical Pharmacology (12.3) ]. Of the 279 patients treated with posaconazole injection in the Posaconazole Injection Study, 52 (19%) were greater than 65 years of age.
No overall differences in the pharmacokinetics and safety were observed between elderly and young subjects during clinical trials, but greater sensitivity of some older individuals cannot be ruled out.
🆘 Overdosage ▾
10 OVERDOSAGE There is no experience with overdosage of posaconazole injection. During the clinical trials, some patients received NOXAFIL Oral Suspension up to 1600 mg/day with no adverse reactions noted that were different from the lower doses. In addition, accidental overdose was noted in one patient who took 1200 mg twice daily NOXAFIL Oral Suspension for 3 days.
No related adverse reactions were noted by the investigator. Posaconazole is not removed by hemodialysis.

12.1Mechanism of Action Posaconazole is an azole antifungal agent [ see Clinical Pharmacology (12.4) ] .
12.2Pharmacodynamics Exposure Response Relationship Prophylaxis: In clinical studies of neutropenic patients who were receiving cytotoxic chemotherapy for acute myelogenous leukemia (AML) or myelodysplastic syndromes (MDS) or hematopoietic stem cell transplant (HSCT) recipients with Graft versus Host Disease (GVHD), a wide range of plasma exposures to posaconazole was noted following administration of NOXAFIL Oral Suspension. A pharmacokinetic-pharmacodynamic analysis of patient data revealed an apparent association between average posaconazole concentrations (Cavg) and prophylactic efficacy ( Table 17 ).
A lower Cavg may be associated with an increased risk of treatment failure, defined as treatment discontinuation, use of empiric systemic antifungal therapy (SAF), or occurrence of breakthrough invasive fungal infections.
