⛔ 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 , 7.2 ) • 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 , 7.2 ) • Ergot alkaloids ( 4.5 , 7.2 ) • 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 , 7.2 )
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 ( 7.2 ) 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 ( 7.2 ) 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 ( 7.2 )] .
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 ( 7.2 )] .
⚠️ 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 , 7.2 ) • 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 ) • Concomitant Use with Midazolam : Posaconazole can prolong hypnotic/sedative effects. Monitor patients and benzodiazepine receptor antagonists should be available. ( 5.7 , 7.2 ) • 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 , 7.2 ) • Breakthrough Fungal Infections : Monitor patients with severe diarrhea or vomiting when receiving posaconazole oral suspension. ( 5.10 ) • 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 , 7.2 )
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 ( 7.2 ) 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 to 85 years of age) administered posaconazole 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 with potentially proarrhythmic conditions.
Do not administer with drugs that are known to pr… [Excerpted — this section continues on DailyMed.]

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 Trials Safety Experience with Posaconazole Oral Suspension: The safety of posaconazole oral suspension has been assessed in 1,844 patients, including: • 605 patients in the active-controlled studies for the prophylaxis of invasive Aspergillus and Candida infections • 557 patients in the active-controlled OPC studies (not refractory to itraconazole or fluconazole) • 239 patients in refractory OPC studies (refractory to itraconazole or fluconazole) (rOPC), and • 443 patients in other patient populations These studies included immunocompromised patients (e.g., patients with hematological malignancy, neutropenia post-chemotherapy, GVHD post HSCT, and HIV infection), as well as non-neutropenic patients.
This patient population was 71% male, had a mean age of 42 years (range 8 to 84 years, 6% of patients were ≥65 years of age and 1% was <18 years of age), and were 64% White, 14% Black, 16% Hispanic. Posaconazole oral suspension therapy was given to 171 patients for ≥6 months, including 58 patients who received posaconazole oral suspension therapy for ≥12 months. Table 10 presents adverse reactions observed at an incidence of >10% in the studies for prophylaxis of invasive Aspergillus and Candida infections.
Table 11 presents adverse reactions observed at an incidence of at least 10% in the OPC/rOPC studies. Prophylaxis of Invasive Aspergillus and Candida Infections (posaconazole oral suspension) : In the two randomized, comparative studies for prophylaxis Aspergillus and Candida infections in those at high risk of developing these infections due to being severely immunocompromised (Posaconazole Oral Suspension Study 1 and 2), the safety of posaconazole oral suspension 200 mg three times a day was compared to fluconazole 400 mg once daily or itraconazole 200 mg twice a day in severely immunocompromised patients.
The most frequently reported adverse reactions (>30%) in these trials were fever, diarrhea, and nausea. The most common adverse reactions leading to discontinuation of posaconazole oral suspension were GI adverse reactions, specifically, nausea (2%), vomiting (2%), and increased hepatic enzymes (2%).

🔄 Drug Interactions ▾
7 DRUG INTERACTIONS Table 15 and Table 17 include drugs with clinically important drug interactions when administered concomitantly with posaconazole and posaconazole PowderMix and instructions for preventing or managing them. Table 16 includes important drug interactions specific to the absorption of posaconazole administered as either posaconazole oral suspension or posaconazole PowderMix. These recommendations are based on either drug interaction studies or predicted interactions due to the expected magnitude of interaction and potential for serious adverse reactions or loss of efficacy [see Clinical Pharmacology ( 12.3 )] .
The following information was derived from data with posaconazole oral suspension or another posaconazole tablet formulation unless otherwise noted. All clinically important drug interactions with posaconazole oral suspension, except for those that affect the absorption of posaconazole (via gastric pH and motility), are considered relevant to clinically important drug interactions with posaconazole injection, posaconazole delayed-release tablets, and posaconazole PowderMix for delayed-release oral suspension [Clinical Pharmacology ( 12.3 )] .
Consult the labeling of concomitantly used drugs to obtain further information about interactions with posaconazole. Interaction Drug Interaction Rifabutin, phenytoin, efavirenz, cimetidine, esomeprazole Avoid coadministration unless the benefit outweighs the risks ( 7.1 , 7.2 ) Other drugs metabolized by CYP3A4 Consider dosage adjustment and monitor for adverse effects and toxicity ( 7.2 ) Digoxin Monitor digoxin plasma concentrations ( 7.2 ) Fosamprenavir, metoclopramide Monitor for breakthrough fungal infections ( 7.3 , 12.3 )
7.1Effects of Other Drugs on Posaconazole 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. Concomitant use of posaconazole with drugs that can decrease the plasma posaconazole concentrations should generally be avoided unless the benefit outweighs the risk.
If such drugs are necessary, patients should be monitored closely for breakthrough fungal infections. Table 15: Drug Interactions Affecting Posaconazole When Administered Concomitantly with Other Drugs UDP-Glucuronidase Inducers Mechanism and Clinical Effect(s) Posaconazole is a UDP-glucuronosyltransferase substrate. Concomitant use of posaconazole with UDP-glucuronidase inducers may decrease posaconazole exposure [see Clinical Pharmacology ( 12.3 )], which may reduce the effectiveness of posaconazole.
Prevention or Management Efavirenz Avoid concomitant use of posaconazole with efavirenz, unless the benefit outweighs the risks. Rifabutin Avoid concomitant use of posaconazole with rifabutin unless the benefit to the patient outweighs the risk. If concomitant use is needed, monitor closely for breakthrough fungal infections.
See Table 17 for rifabutin monitoring considerations when posaconazole affects rifabutin via CYP3A4 inhibition. Phenytoin Avoid concomitant use of posaconazole with phenytoin unless the benefit to the patient outweighs the risk. If concomitant use is needed, monitor for breakthrough fungal infections.
See Table 17 for phenytoin monitoring considerations when posaconazole affects phenytoin via CYP3A4 inhibition. Fosamprenavir Mechanism and Clinical Effect(s) Concomitant use of posaconazole with fosamprenavir may lead to decreased posaconazole plasma concentrations [see Clinical Pharmacology ( 12.3 )], which may reduce effectiveness of posaconazole. Prevention or Management If concomitant use of posaconazole with fosamprenavir is needed, monitor closely for breakthrough fungal infections.

👥 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 13 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 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, doses of ≥ 3 times the clinical exposure caused an increase in resorptions (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 populations 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 three dosage forms (injection, delayed-release tablets, oral suspension) and one posaconazole PowderMix (for delayed-release oral suspension) dosage form are different products; are approved for different pediatric indications, age groups, and weights; have different dosing regimens; and have different preparation and administration instructions. Therefore, select the recommended dosage form based on the pediatric indication, age group, and weight [see Dosage and Administration ( 2.1 )] . Prophylaxis of Invasive Aspergillus and Candida Infections The safety and effectiveness of posaconazole oral suspension have been established for the prophylaxis of invasive Aspergillus and Candida infections in pediatric patients 13 years of age and older who are at high risk of developing these infections due to being s… [Excerpted — this section continues on DailyMed.]

Use of posaconazole for these pediatric indications is supported by adequate and well controlled studies of posaconazole in adults and pediatric patients aged 13 years of age and older [see Clinical Pharmacology ( 12.3 ) and Clinical studies ( 14 )] . The safety and effectiveness of posaconazole and posaconazole PowderMix have not been established in pediatric patients less than 2 years of age. Treatment of Oropharyngeal Candidiasis, including Refractory to Itraconazole and/or Fluconazole The safety and effectiveness of posaconazole oral suspension have been established for the treatment of oropharyngeal candidiasis (OPC), including OPC refractory (rOPC) to itraconazole and/or fluconazole in pediatric patients 13 years of age and older.
Use of posaconazole oral suspension for this pediatric indication is supported by adequate and well controlled studies in adults and pediatric patients 13 years of age and older [see Clinical studies ( 14.4 )]. The posaconazole injection, posaconazole delayed-release tablets, and posaconazole PowderMix products are not approved for the treatment of oropharyngeal candidiasis in pediatric patients. Posaconazole Oral Suspension is the only dosage form approved for the treatment of OPC and rOPC in pediatric patients [see Dosage and Administration ( 2.4 )].
The safety and effectiveness of posaconazole oral suspension for the treatment of OPC and rOPC have not been established in pediatric patients less than 13 years of age.
🧓 Geriatric Use ▾
8.5Geriatric Use No overall differences in the safety or effectiveness of posaconazole oral suspension were observed between geriatric patients and younger adult patients in the clinical trials; therefore, the recommended dosage in geriatric patients is the same as that for younger adult patients. No clinically meaningful differences in posaconazole pharmacokinetics were observed in posaconazole-treated geriatric patients compared to posaconazole-treated younger adult patients during clinical trials [see Clinical Pharmacology ( 12.3 )] . • Of the 605 patients treated with posaconazole oral suspension in posaconazole Oral Suspension Study 1 and Study 2 (prophylaxis of invasive Aspergillus and Candida infections in those at high risk of developing these infections due to being severely immunocompromised), 63 (10%) patients were ≥65 years of age. • In studies of posaconazole for an unapproved indication, 48 patients treated with posaconazole oral suspension (greater than or equal to 800 mg/day (eight times the maximum recommended maintenance dosage for the treatment of OPC)) were ≥65 years of age.
🆘 Overdosage ▾
10 OVERDOSAGE During the clinical trials, some patients received posaconazole oral suspension up to 1,600 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 1,200 mg twice daily posaconazole oral suspension for 3 days. No related adverse reactions were noted by the investigator. Posaconazole is not removed by hemodialysis.

12.2Pharmacodynamics Exposure Response Relationship: Prophylaxis of Invasive Aspergillus and Candida Infections in Adults Who Are at High Risk of Developing These Infections Due to Being Severely Immunocompromised : 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 posaconazole exposures was noted following administration of posaconazole oral suspension.
A pharmacokinetic-pharmacodynamic analysis of patient data revealed an apparent association between average posaconazole concentrations (Cavg) and prophylactic efficacy ( Table 18 ). 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.

💬 Information for Patients ▾
17 PATIENT COUNSELING INFORMATION Advise the patient to read the FDA-approved patient labeling (Patient Information). Important Administration Instructions Advise patients to take each dose of posaconazole oral suspension during or immediately (i.e., within 20 minutes) following a full meal. In patients who cannot eat a full meal, each dose of posaconazole oral suspension should be administered with a liquid nutritional supplement or an acidic carbonated beverage (e.g., ginger ale) in order to enhance absorption.
Instruct patients that if they miss a dose, they should take it as soon as they remember. However, if it is almost time for the next dose, they should be instructed to skip the missed dose and go back to the regular schedule. Patients should not double their next dose or take more than the prescribed dose.
Drug Interactions Advise patients to inform their physician immediately if they: • develop severe diarrhea or vomiting. • are currently taking drugs that are known to prolong the QTc interval and are metabolized through CYP3A4. • are currently taking a cyclosporine or tacrolimus, or they notice swelling in an arm or leg or shortness of breath. • are taking other drugs or before they begin taking other drugs as certain drugs can decrease or increase the plasma concentrations of posaconazole. Serious and Potentially Serious Adverse Reactions Advise patients to inform their physician immediately if they: • notice a change in heart rate or heart rhythm, or have a heart condition or circulatory disease.
Posaconazole can be administered with caution to patients with potentially proarrhythmic conditions. • are pregnant, plan to become pregnant, or are nursing. • have liver disease or develop itching, nausea or vomiting, their eyes or skin turn yellow, they feel more tired than usual or feel like they have the flu. • have ever had an allergic reaction to other antifungal medicines such as ketoconazole, fluconazole, itraconazole, or voriconazole.

🍼 Nursing Mothers ▾
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.
🧬 Pharmacokinetics ▾
12.3Pharmacokinetics General Pharmacokinetic Characteristics Dose-proportional increases in plasma exposure (AUC) to posaconazole oral suspension were observed following single oral doses from 50 mg to 800 mg and following multiple-dose administration from 50 mg twice daily to 400 mg twice daily in healthy volunteers. No further increases in exposure were observed when the dose of the oral suspension increased from 400 mg twice daily to 600 mg twice daily in febrile neutropenic patients or those with refractory invasive fungal infections.

Steady-state plasma concentrations are attained at 7 to 10 days following multiple-dose administration. Following single-dose administration of 200 mg, the mean AUC and C max of posaconazole are approximately 3 times higher when the oral suspension is administered with a nonfat meal and approximately 4 times higher when administered with a high-fat meal (~50 gm fat) relative to the fasted state. Following single-dose administration of posaconazole oral suspension 400 mg, the mean AUC and C max of posaconazole are approximately 3 times higher when administered with a liquid nutritional supplement (14 gm fat) relative to the fasted state (see Table 24 ).
In addition, the effects of varying gastric administration conditions on the C max and AUC of posaconazole oral suspension in healthy volunteers have been investigated and are shown in Table 25 . To assure attainment of adequate plasma concentrations, it is recommended to administer posaconazole oral suspension during or immediately following a full meal. In patients who cannot eat a full meal, posaconazole oral suspension should be taken with a liquid nutritional supplement or an acidic carbonated beverage (e.g., ginger ale).

14 CLINICAL STUDIES
14.2Prophylaxis of Aspergillus and Candida Infections with Posaconazole Oral Suspension Two randomized, controlled studies were conducted using posaconazole as prophylaxis for the prevention of invasive fungal infections (IFIs) among patients at high risk due to severely compromised immune systems. The first study (Posaconazole Oral Suspension Study 1) was a randomized, double-blind trial that compared posaconazole oral suspension (200 mg three times a day) with fluconazole capsules (400 mg once daily) as prophylaxis against invasive fungal infections in allogeneic hematopoietic stem cell transplant (HSCT) recipients with Graft versus Host Disease (GVHD).
Efficacy of prophylaxis was evaluated using a composite endpoint of proven/probable IFIs, death, or treatment with systemic antifungal therapy (patients may have met more than one of these criteria). This assessed all patients while on study therapy plus 7 days and at 16 weeks post-randomization. The mean duration of therapy was comparable between the 2 treatment groups (80 days, posaconazole oral suspension; 77 days, fluconazole).

13.1Carcinogenesis, Mutagenesis, Impairment of Fertility Carcinogenesis: No drug-related neoplasms were recorded in rats or mice treated with posaconazole for 2 years at doses higher than the clinical dose. In a 2-year carcinogenicity study, rats were given posaconazole orally at doses up to 20 mg/kg (females), or 30 mg/kg (males). These doses are equivalent to 3.9- or 3.5 times the exposure achieved with a 400 mg twice daily oral suspension regimen, respectively, based on steady-state AUC in healthy volunteers administered a high-fat meal (400 mg twice daily oral suspension regimen).
In the mouse study, mice were treated at oral doses up to 60 mg/kg/day or 4.8 times the exposure achieved with a 400 mg twice daily oral suspension regimen. Mutagenesis: Posaconazole was not genotoxic or clastogenic when evaluated in bacterial mutagenicity (Ames), a chromosome aberration study in human peripheral blood lymphocytes, a Chinese hamster ovary cell mutagenicity study, and a mouse bone marrow micronucleus study. Impairment of Fertility: Posaconazole had no effect on fertility of male rats at a dose up to 180 mg/kg (1.7 × the 400 mg twice daily oral suspension regimen based on steady-state plasma concentrations in healthy volunteers) or female rats at a dose up to 45 mg/kg (2.2 × the 400 mg twice daily oral suspension regimen).

Patient Information Posaconazole Oral Suspension (poe’ sa kon’ a zole) Rx only What is posaconazole oral suspension? Posaconazole oral suspension is a prescription medicine used in adults and children to help prevent or treat fungal infections that can spread throughout your body (invasive fungal infections). These infections are caused by fungi called Aspergillus or Candida .
Posaconazole is used in people who have an increased chance of getting these infections due to a weak immune system. These include people who have had a hematopoietic stem cell transplantation (bone marrow transplant) with graft versus host disease or those with a low white blood cell count due to chemotherapy for blood cancers (hematologic malignancies). Posaconazole oral suspension is used for: • prevention of fungal infections in adults and children 13 years of age and older.
Posaconazole oral suspension is also used to treat a fungal infection called "thrush" caused by Candida in your mouth or throat area. Posaconazole oral suspension can be used as the first treatment for thrush, or as another treatment for thrush after itraconazole or fluconazole treatment has not worked. Posaconazole oral suspension is for adults and children 13 years of age and older.
It is not known if Posaconazole oral suspension is safe and effective in children under 13 years of age for the treatment of thrush as the first treatment for thrush, or as another treatment for thrush after itraconazole or fluconazole treatment has not worked. Do not take posaconazole if you: • are allergic to posaconazole, any of the ingredients in posaconazole, or other azole antifungal medicines. See the end of this Patient Information leaflet for a complete list of ingredients in posaconazole. • are taking any of the following medicines: o sirolimus o pimozide o quinidine o certain statin medicines that lower cholesterol (atorvastatin, lovastatin, simvastatin) o ergot alkaloids (ergotamine, dihydroergotamine) • have chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL) and you have just started taking venetoclax or your venetoclax dose is being slowly increased.
Ask your healthcare provider or pharmacist if you are not sure if you are taking any of these medicines. Do not start taking a new medicine without talking to your healthcare provider or pharmacist. Before you take posaconazole tell your healthcare provider about all of your medical conditions, including if you: • are taking certain medicines that lower your immune system like cyclosporine or tacrolimus. • are taking certain drugs for HIV infection, such as ritonavir, atazanavir, efavirenz, or fosamprenavir.
Efavirenz and fosamprenavir can cause a decrease in the posaconazole levels in your body. Efavirenz and fosamprenavir should not be taken with posaconazole. • are taking midazolam, a hypnotic and sedative medicine. • are taking vincristine, vinblastine and other “vinca alkaloids” (medicines used to treat cancer). • are taking venetoclax, a medicine used to treat cancer. • have or had liver problems. • have or had kidney problems. • have or had an abnormal heart rate or rhythm, heart problems, or blood circulation problems. • are pregnant or plan to become pregnant.
It is not known if posaconazole will harm your unborn baby. • are breastfeeding or plan to breastfeed. It is not known if posaconazole passes into your breast milk. You and your healthcare provider should decide if you will take posaconazole or breastfeed.
You should not do both. Tell your healthcare provider about all the medicines you take , including prescription and over-the-counter medicines, vitamins, and herbal supplements. Posaconazole can affect the way other medicines work, and other medicines can affect the way posaconazole works, and can cause serious side effects.
Especially tell your healthcare provider if you take : • rifabutin or phenytoin. If you are taking these medicines, you should not take posaconazole oral suspension. • cimetidine or… [Excerpted — this section continues on DailyMed.]
