🚨 Boxed Warning ▾
BOXED WARNING Congestive Heart Failure, Cardiac Effects and Drug Interactions Congestive Heart Failure and Cardiac Effects SPORANOX ® (itraconazole) Capsules should not be administered for the treatment of onychomycosis in patients with evidence of ventricular dysfunction such as congestive heart failure (CHF) or a history of CHF. If signs or symptoms of congestive heart failure occur during administration of SPORANOX ® Capsules, discontinue administration. When itraconazole was administered intravenously to dogs and healthy human volunteers, negative inotropic effects were seen.
(See CONTRAINDICATIONS , WARNINGS , PRECAUTIONS: Drug Interactions , ADVERSE REACTIONS: Postmarketing Experience , and CLINICAL PHARMACOLOGY: Special Populations for more information.) Drug Interactions Coadministration of a number of CYP3A4 substrates are contraindicated with SPORANOX ® . Some examples of drugs that are contraindicated for coadministration with SPORANOX ® Capsules are: methadone, disopyramide, dofetilide, dronedarone, quinidine, isavuconazole, ergot alkaloids (such as dihydroergotamine, ergometrine (ergonovine), ergotamine, methylergometrine (methylergonovine)), irinotecan, lurasidone, oral midazolam, pimozide, triazolam, felodipine, nisoldipine, ivabradine, ranolazine, eplerenone, cisapride, naloxegol, lomitapide, lovastatin, simvastatin, avanafil, ticagrelor, finerenone, voclosporin.
Coadministration with colchicine, fesoterodine and solifenacin is contraindicated in subjects with varying degrees of renal or hepatic impairment. Coadministration with eliglustat is contraindicated in subjects that are poor or intermediate metabolizers of CYP2D6 and in subjects taking strong or moderate CYP2D6 inhibitors. Coadministration with venetoclax is contraindicated in patients with chronic lymphocytic leukemia (CLL)/small lymphocytic lymphoma (SLL) during the dose initiation and ramp-up phase of venetoclax.
See PRECAUTIONS: Drug Interactions Section for specific examples. Coadministration with itraconazole can cause elevated plasma concentrations of these drugs and may increase or prolong both the pharmacologic effects and/or adverse reactions to these drugs. For example, increased plasma concentrations of some of these drugs can lead to QT prolongation and ventricular tachyarrhythmias including occurrences of torsade de pointes, a potentially fatal arrhythmia.
See CONTRAINDICATIONS and WARNINGS Sections, and PRECAUTIONS: Drug Interactions Section for specific examples.
🎯 Indications and Usage ▾
INDICATIONS AND USAGE SPORANOX ® (itraconazole) Capsules are indicated for the treatment of the following fungal infections in immunocompromised and non-immunocompromised patients: Blastomycosis, pulmonary and extrapulmonary Histoplasmosis, including chronic cavitary pulmonary disease and disseminated, non-meningeal histoplasmosis, and Aspergillosis, pulmonary and extrapulmonary, in patients who are intolerant of or who are refractory to amphotericin B therapy. Specimens for fungal cultures and other relevant laboratory studies (wet mount, histopathology, serology) should be obtained before therapy to isolate and identify causative organisms.
Therapy may be instituted before the results of the cultures and other laboratory studies are known; however, once these results become available, antiinfective therapy should be adjusted accordingly. SPORANOX ® Capsules are also indicated for the treatment of the following fungal infections in non-immunocompromised patients: Onychomycosis of the toenail, with or without fingernail involvement, due to dermatophytes (tinea unguium), and Onychomycosis of the fingernail due to dermatophytes (tinea unguium). Prior to initiating treatment, appropriate nail specimens for laboratory testing (KOH preparation, fungal culture, or nail biopsy) should be obtained to confirm the diagnosis of onychomycosis.
(See CLINICAL PHARMACOLOGY: Special Populations , CONTRAINDICATIONS , WARNINGS , and ADVERSE REACTIONS: Postmarketing Experience for more information.) Description of Clinical Studies Blastomycosis Analyses were conducted on data from two open-label, non-concurrently controlled studies (N=73 combined) in patients with normal or abnormal immune status. The median dose was 200 mg/day. A response for most signs and symptoms was observed within the first 2 weeks, and all signs and symptoms cleared between 3 and 6 months.
Results of these two studies demonstrated substantial evidence of the effectiveness of itraconazole for the treatment of blastomycosis compared with the natural history of untreated cases. Histoplasmosis Analyses were conducted on data from two open-label, non-concurrently controlled studies (N=34 combined) in patients with normal or abnormal immune status (not including HIV-infected patients). The median dose was 200 mg/day.
A response for most signs and symptoms was observed within the first 2 weeks, and all signs and symptoms cleared between 3 and 12 months. Results of these two studies demonstrated substantial evidence of the effectiveness of itraconazole for the treatment of histoplasmosis, compared with the natural history of untreated cases. Histoplasmosis in HIV-infected patients Data from a small number of HIV-infected patients suggested that the response rate of histoplasmosis in HIV-infected patients is similar to that of non-HIV-infected patients.
The clinical course of histoplasmosis in HIV-infected patients is more severe and usually requires maintenance therapy to prevent relapse. Aspergillosis Analyses were conducted on data from an open-label, "single-patient-use" protocol designed to make itraconazole available in the U.S. for patients who either failed or were intolerant of amphotericin B therapy (N=190). The findings were corroborated by two smaller open-label studies (N=31 combined) in the same patient population.
Most adult patients were treated with a daily dose of 200 to 400 mg, with a median duration of 3 months. Results of these studies demonstrated substantial evidence of effectiveness of itraconazole as a second-line therapy for the treatment of aspergillosis compared with the natural history of the disease in patients who either failed or were intolerant of amphotericin B therapy. Onychomycosis of the toenail Analyses were conducted on data from three double-blind, placebo-controlled studies (N=214 total; 110 given SPORANOX ® Capsules) in which patients with onychomycosis of the toenails received 200 mg of SPORANOX ® Capsules once daily for 12 consecutive we…
⏱️ Dosage and Administration ▾
DOSAGE AND ADMINISTRATION SPORANOX ® (itraconazole) Capsules should be taken with a full meal to ensure maximal absorption. SPORANOX ® (itraconazole) Capsules must be swallowed whole. SPORANOX ® Capsules is a different preparation than SPORANOX ® Oral Solution and should not be used interchangeably.
Treatment of Blastomycosis and Histoplasmosis The recommended dose is 200 mg once daily (2 capsules). If there is no obvious improvement, or there is evidence of progressive fungal disease, the dose should be increased in 100-mg increments to a maximum of 400 mg daily. Doses above 200 mg/day should be given in two divided doses.
Treatment of Aspergillosis A daily dose of 200 to 400 mg is recommended. Treatment in Life-Threatening Situations In life-threatening situations, a loading dose should be used. Although clinical studies did not provide for a loading dose, it is recommended, based on pharmacokinetic data, that a loading dose of 200 mg (2 capsules) three times daily (600 mg/day) be given for the first 3 days of treatment.
Treatment should be continued for a minimum of three months and until clinical parameters and laboratory tests indicate that the active fungal infection has subsided. An inadequate period of treatment may lead to recurrence of active infection. SPORANOX ® Capsules and SPORANOX ® Oral Solution should not be used interchangeably.
Only the oral solution has been demonstrated effective for oral and/or esophageal candidiasis. Treatment of Onychomycosis Toenails with or without fingernail involvement The recommended dose is 200 mg (2 capsules) once daily for 12 consecutive weeks. Treatment of Onychomycosis Fingernails only The recommended dosing regimen is 2 treatment pulses, each consisting of 200 mg (2 capsules) b.i.d.
(400 mg/day) for 1 week. The pulses are separated by a 3-week period without SPORANOX ® . Use in Patients with Renal Impairment Limited data are available on the use of oral itraconazole in patients with renal impairment.
Caution should be exercised when this drug is administered in this patient population. (See CLINICAL PHARMACOLOGY: Special Populations and PRECAUTIONS .) Use in Patients with Hepatic Impairment Limited data are available on the use of oral itraconazole in patients with hepatic impairment. Caution should be exercised when this drug is administered in this patient population.

⛔ Contraindications ▾
CONTRAINDICATIONS Congestive Heart Failure SPORANOX ® (itraconazole) Capsules should not be administered for the treatment of onychomycosis in patients with evidence of ventricular dysfunction such as congestive heart failure (CHF) or a history of CHF. (See BOXED WARNING , WARNINGS , PRECAUTIONS: Drug Interactions-Calcium Channel Blockers, ADVERSE REACTIONS: Postmarketing Experience , and CLINICAL PHARMACOLOGY: Special Populations .) Drug Interactions Coadministration of a number of CYP3A4 substrates are contraindicated with SPORANOX ® .
Some examples of drugs for which plasma concentrations increase are: methadone, disopyramide, dofetilide, dronedarone, quinidine, isavuconazole, ergot alkaloids (such as dihydroergotamine, ergometrine (ergonovine), ergotamine, methylergometrine (methylergonovine)), irinotecan, lurasidone, oral midazolam, pimozide, triazolam, felodipine, nisoldipine, ivabradine, ranolazine, eplerenone, cisapride, naloxegol, lomitapide, lovastatin, simvastatin, avanafil, ticagrelor, finerenone, voclosporin. In addition, coadministration with colchicine, fesoterodine, and solifenacin is contraindicated in subjects with varying degrees of renal or hepatic impairment, and coadministration with eliglustat is contraindicated in subjects that are poor or intermediate metabolizers of CYP2D6 and in subjects taking strong or moderate CYP2D6 inhibitors.
(See PRECAUTIONS: Drug Interactions Section for specific examples.) This increase in drug concentrations caused by coadministration with itraconazole may increase or prolong both the pharmacologic effects and/or adverse reactions to these drugs. For example, increased plasma concentrations of some of these drugs can lead to QT prolongation and ventricular tachyarrhythmias including occurrences of torsade de pointes, a potentially fatal arrhythmia. Some specific examples are listed in PRECAUTIONS: Drug Interactions.
Coadministration with venetoclax is contraindicated in patients with CLL/SLL during the dose initiation and ramp-up phase of venetoclax due to the potential for an increased risk of tumor lysis syndrome. SPORANOX ® should not be administered for the treatment of onychomycosis to pregnant patients or to women contemplating pregnancy. SPORANOX ® is contraindicated for patients who have shown hypersensitivity to itraconazole.
There is limited information regarding cross-hypersensitivity between itraconazole and other azole antifungal agents. Caution should be used when prescribing SPORANOX ® to patients with hypersensitivity to other azoles.
⚠️ Warnings ▾
WARNINGS Hepatic Effects SPORANOX ® has been associated with rare cases of serious hepatotoxicity, including liver failure and death. Some of these cases had neither pre-existing liver disease nor a serious underlying medical condition, and some of these cases developed within the first week of treatment. If clinical signs or symptoms develop that are consistent with liver disease, treatment should be discontinued and liver function testing performed.
Continued SPORANOX ® use or reinstitution of treatment with SPORANOX ® is strongly discouraged unless there is a serious or life-threatening situation where the expected benefit exceeds the risk. (See PRECAUTIONS: Information for Patients and ADVERSE REACTIONS .) Cardiac Dysrhythmias Life-threatening cardiac dysrhythmias and/or sudden death have occurred in patients using drugs such as cisapride, pimozide, methadone, or quinidine concomitantly with SPORANOX ® and/or other CYP3A4 inhibitors. Concomitant administration of these drugs with SPORANOX ® is contraindicated.
(See BOXED WARNING , CONTRAINDICATIONS , and PRECAUTIONS: Drug Interactions .) Cardiac Disease SPORANOX ® Capsules should not be administered for the treatment of onychomycosis in patients with evidence of ventricular dysfunction such as congestive heart failure (CHF) or a history of CHF. SPORANOX ® Capsules should not be used for other indications in patients with evidence of ventricular dysfunction unless the benefit clearly outweighs the risk. For patients with risk factors for congestive heart failure, physicians should carefully review the risks and benefits of SPORANOX ® therapy.
These risk factors include cardiac disease such as ischemic and valvular disease; significant pulmonary disease such as chronic obstructive pulmonary disease; and renal failure and other edematous disorders. Such patients should be informed of the signs and symptoms of CHF, should be treated with caution, and should be monitored for signs and symptoms of CHF during treatment. If signs or symptoms of CHF appear during administration of SPORANOX ® Capsules, discontinue administration.
Itraconazole has been shown to have a negative inotropic effect. When itraconazole was administered intravenously to anesthetized dogs, a dose-related negative inotropic effect was documented. In a healthy volunteer study of itraconazole intravenous infusion, transient, asymptomatic decreases in left ventricular ejection fraction were observed using gated SPECT imaging; these resolved before the next infusion, 12 hours later.
SPORANOX ® has been associated with reports of congestive heart failure. In postmarketing experience, heart failure was more frequently reported in patients receiving a total daily dose of 400 mg although there were also cases reported among those receiving lower total daily doses. Calcium channel blockers can have negative inotropic effects which may be additive to those of itraconazole.
In addition, itraconazole can inhibit the metabolism of calcium channel blockers. Therefore, caution should be used when co-administering itraconazole and calcium channel blockers due to an increased risk of CHF. Concomitant administration of SPORANOX ® and felodipine or nisoldipine is contraindicated.
Cases of CHF, peripheral edema, and pulmonary edema have been reported in the postmarketing period among patients being treated for onychomycosis and/or systemic fungal infections. (See CLINICAL PHARMACOLOGY: Special Populations , CONTRAINDICATIONS , PRECAUTIONS: Drug Interactions , and ADVERSE REACTIONS: Postmarketing Experience for more information.) Pseudoaldosteronism Pseudoaldosteronism, manifested by the onset of hypertension or worsening of hypertension, and abnormal laboratory findings (hypokalemia, low serum renin and aldosterone, and elevated 11-deoxycortisol), has been reported with itraconazole use in the postmarketing setting.
Monitor blood pressure and potassium levels and manage as necessary. Management of pseudoaldosteronism may include…
🤒 Adverse Reactions ▾
ADVERSE REACTIONS Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice. SPORANOX ® has been associated with rare cases of serious hepatotoxicity, including liver failure and death. Some of these cases had neither pre-existing liver disease nor a serious underlying medical condition.
If clinical signs or symptoms develop that are consistent with liver disease, treatment should be discontinued and liver function testing performed. The risks and benefits of SPORANOX ® use should be reassessed. (See WARNINGS: Hepatic Effects and PRECAUTIONS: Hepatotoxicity and Information for Patients .) Adverse Events in the Treatment of Systemic Fungal Infections Adverse event data were derived from 602 patients treated for systemic fungal disease in U.S. clinical trials who were immunocompromised or receiving multiple concomitant medications.
Treatment was discontinued in 10.5% of patients due to adverse events. The median duration before discontinuation of therapy was 81 days (range: 2 to 776 days). The table lists adverse events reported by at least 1% of patients.

🔄 Drug Interactions ▾
Drug Interactions Effect of SPORANOX ® on Other Drugs Itraconazole and its major metabolite, hydroxy-itraconazole, are potent CYP3A4 inhibitors. Itraconazole is an inhibitor of the drug transporters P-glycoprotein and breast cancer resistance protein (BCRP). Consequently, SPORANOX ® has the potential to interact with many concomitant drugs resulting in either increased or sometimes decreased concentrations of the concomitant drugs.
Increased concentrations may increase the risk of adverse reactions associated with the concomitant drug which can be severe or life-threatening in some cases (e.g., QT prolongation, torsade de pointes, respiratory depression, hepatic adverse reactions, hypersensitivity reactions, myelosuppression, hypotension, seizures, angioedema, atrial fibrillation, bradycardia, priapism). Reduced concentrations of concomitant drugs may reduce their efficacy. Table 1 lists examples of drugs that may have their concentrations affected by itraconazole, but it is not a comprehensive list.
Refer to the approved product labeling to become familiar with the interaction pathways, risk potential, and specific actions to be taken with regards to each concomitant drug prior to initiating therapy with SPORANOX ® . Although many of the clinical drug interactions in Table 1 are based on information with a similar azole antifungal, ketoconazole, these interactions are expected to occur with SPORANOX ® .

🤰 Pregnancy ▾
Pregnancy Teratogenic Effects Itraconazole was found to cause a dose-related increase in maternal toxicity, embryotoxicity, and teratogenicity in rats at dosage levels of approximately 40–160 mg/kg/day (1-4 times the MRHD based on body surface area comparisons), and in mice at dosage levels of approximately 80 mg/kg/day (1 time the MRHD based on body surface area comparisons). Itraconazole has been shown to cross the placenta in a rat model. In rats, the teratogenicity consisted of major skeletal defects; in mice, it consisted of encephaloceles and/or macroglossia.
There are no studies in pregnant women. SPORANOX ® should be used for the treatment of systemic fungal infections in pregnancy only if the benefit outweighs the potential risk. SPORANOX ® should not be administered for the treatment of onychomycosis to pregnant patients or to women contemplating pregnancy.
SPORANOX ® should not be administered to women of childbearing potential for the treatment of onychomycosis unless they are using effective measures to prevent pregnancy and they begin therapy on the second or third day following the onset of menses. Highly effective contraception should be continued throughout SPORANOX ® therapy and for 2 months following the end of treatment. During postmarketing experience, cases of congenital abnormalities have been reported.
(See ADVERSE REACTIONS: Postmarketing Experience .)
🧒 Pediatric Use ▾
Pediatric Use The efficacy and safety of SPORANOX ® have not been established in pediatric patients. The long-term effects of itraconazole on bone growth in children are unknown. In three toxicology studies using rats, itraconazole induced bone defects at dosage levels as low as 20 mg/kg/day (0.5 times the MRHD of 400 mg based on body surface area comparisons).
The induced defects included reduced bone plate activity, thinning of the zona compacta of the large bones, and increased bone fragility. At a dosage level of 80 mg/kg/day (2 times the MRHD based on body surface area comparisons) over 1 year or 160 mg/kg/day (4 times the MRHD based on body surface area comparisons) for 6 months, itraconazole induced small tooth pulp with hypocellular appearance in some rats.
🧓 Geriatric Use ▾
Geriatric Use Clinical studies of SPORANOX ® Capsules did not include sufficient numbers of subjects aged 65 years and over to determine whether they respond differently from younger subjects. It is advised to use SPORANOX ® Capsules in these patients only if it is determined that the potential benefit outweighs the potential risks. In general, it is recommended that the dose selection for an elderly patient should be taken into consideration, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.
Transient or permanent hearing loss has been reported in elderly patients receiving treatment with itraconazole. Several of these reports included concurrent administration of quinidine which is contraindicated. (See BOXED WARNING: Drug Interactions , CONTRAINDICATIONS: Drug Interactions and PRECAUTIONS: Drug Interactions .)
🆘 Overdosage ▾
OVERDOSAGE Itraconazole is not removed by dialysis. In the event of accidental overdosage, supportive measures should be employed. Contact a certified poison control center for the most up to date information on the management of SPORANOX ® Capsules overdosage (1-800-222-1222 or www.poison.org).
In general, adverse events reported with overdose have been consistent with adverse drug reactions already listed in this package insert for itraconazole. (See ADVERSE REACTIONS .)
🧬 Clinical Pharmacology ▾
CLINICAL PHARMACOLOGY Pharmacokinetics and Metabolism General Pharmacokinetic Characteristics Peak plasma concentrations of itraconazole are reached within 2 to 5 hours following oral administration. As a consequence of non-linear pharmacokinetics, itraconazole accumulates in plasma during multiple dosing. Steady-state concentrations are generally reached within about 15 days, with C max values of 0.5 μg/mL, 1.1 μg/mL and 2.0 μg/mL after oral administration of 100 mg once daily, 200 mg once daily and 200 mg b.i.d., respectively.
The terminal half-life of itraconazole generally ranges from 16 to 28 hours after single dose and increases to 34 to 42 hours with repeated dosing. Once treatment is stopped, itraconazole plasma concentrations decrease to an almost undetectable concentration within 7 to 14 days, depending on the dose and duration of treatment. Itraconazole mean total plasma clearance following intravenous administration is 278 mL/min.
Itraconazole clearance decreases at higher doses due to saturable hepatic metabolism. Absorption Itraconazole is rapidly absorbed after oral administration. Peak plasma concentrations of itraconazole are reached within 2 to 5 hours following an oral capsule dose.
The observed absolute oral bioavailability of itraconazole is about 55%. The oral bioavailability of itraconazole is maximal when SPORANOX ® (itraconazole) Capsules are taken immediately after a full meal. Absorption of itraconazole capsules is reduced in subjects with reduced gastric acidity, such as subjects taking medications known as gastric acid secretion suppressors (e.g., H 2 -receptor antagonists, proton pump inhibitors) or subjects with achlorhydria caused by certain diseases.
(See PRECAUTIONS: Drug Interactions .) Absorption of itraconazole under fasted conditions in these subjects is increased when SPORANOX ® Capsules are administered with an acidic beverage (such as a non-diet cola). When SPORANOX ® Capsules were administered as a single 200-mg dose under fasted conditions with non-diet cola after ranitidine pretreatment, a H 2 -receptor antagonist, itraconazole absorption was comparable to that observed when SPORANOX ® Capsules were administered alone. (See PRECAUTIONS: Drug Interactions .) Itraconazole exposure is lower with the Capsule formulation than with the Oral Solution when the same dose of drug is given.
(See WARNINGS .) Distribution Most of the itraconazole in plasma is bound to protein (99.8%), with albumin being the main binding component (99.6% for the hydroxy-metabolite). It has also a marked affinity for lipids. Only 0.2% of the itraconazole in plasma is present as free drug.
Itraconazole is distributed in a large apparent volume in the body (>700 L), suggesting extensive distribution into tissues. Concentrations in lung, kidney, liver, bone, stomach, spleen and muscle were found to be two to three times higher than corresponding concentrations in plasma, and the uptake into keratinous tissues, skin in particular, up to four times higher. Concentrations in the cerebrospinal fluid are much lower than in plasma.
Metabolism Itraconazole is extensively metabolized by the liver into a large number of metabolites. In vitro studies have shown that CYP3A4 is the major enzyme involved in the metabolism of itraconazole. The main metabolite is hydroxy-itraconazole, which has in vitro antifungal activity comparable to itraconazole; trough plasma concentrations of this metabolite are about twice those of itraconazole.
Excretion Itraconazole is excreted mainly as inactive metabolites in urine (35%) and in feces (54%) within one week of an oral solution dose. Renal excretion of itraconazole and the active metabolite hydroxy-itraconazole account for less than 1% of an intravenous dose. Based on an oral radiolabeled dose, fecal excretion of unchanged drug ranges from 3% to 18% of the dose.
As re-distribution of itraconazole from keratinous tissues appears to be negligible, elimination of itraconazole from these tissues…
🧬 Mechanism of Action ▾
Mechanism of Action In vitro studies have demonstrated that itraconazole inhibits the cytochrome P450-dependent synthesis of ergosterol, which is a vital component of fungal cell membranes.

📋 Description ▾
DESCRIPTION SPORANOX ® is the brand name for itraconazole, an azole antifungal agent. Itraconazole is a 1:1:1:1 racemic mixture of four diastereomers (two enantiomeric pairs), each possessing three chiral centers. It may be represented by the following structural formula and nomenclature: (±)-1-[( R *)- sec -butyl]-4-[ p -[4-[ p -[[(2 R *,4 S *)-2-(2,4-dichlorophenyl)-2-(1 H -1,2,4-triazol-1-ylmethyl)-1,3-dioxolan-4-yl]methoxy]phenyl]-1-piperazinyl]phenyl]-Δ 2 -1,2,4-triazolin-5-one mixture with (±)-1-[( R *)- sec -butyl]-4-[ p -[4-[ p -[[(2 S *,4 R *)-2-(2,4-dichlorophenyl)-2-(1 H -1,2,4-triazol-1-ylmethyl)-1,3-dioxolan-4-yl]methoxy]phenyl]-1-piperazinyl]phenyl]-Δ 2 -1,2,4-triazolin-5-one or (±)-1-[( RS )- sec -butyl]-4-[ p -[4-[ p -[[(2 R ,4 S )-2-(2,4-dichlorophenyl)-2-(1 H -1,2,4-triazol-1-ylmethyl)-1,3-dioxolan-4-yl]methoxy]phenyl]-1-piperazinyl]phenyl]-Δ 2 -1,2,4-triazolin-5-one Itraconazole has a molecular formula of C 35 H 38 Cl 2 N 8 O 4 and a molecular weight of 705.64.

💬 Information for Patients ▾
Information for Patients The topical effects of mucosal exposure may be different between the SPORANOX ® Capsules and Oral Solution. Only the Oral Solution has been demonstrated effective for oral and/or esophageal candidiasis. SPORANOX ® Capsules should not be used interchangeably with SPORANOX ® Oral Solution.
Instruct patients to take SPORANOX ® Capsules with a full meal. SPORANOX ® Capsules must be swallowed whole. Instruct patients about the signs and symptoms of congestive heart failure, and if these signs or symptoms occur during SPORANOX ® administration, they should discontinue SPORANOX ® and contact their healthcare provider immediately.
Instruct patients to stop SPORANOX ® treatment immediately and contact their healthcare provider if any signs and symptoms suggestive of liver dysfunction develop. Such signs and symptoms may include unusual fatigue, anorexia, nausea and/or vomiting, jaundice, dark urine, or pale stools. Instruct patients to contact their physician before taking any concomitant medications with itraconazole to ensure there are no potential drug interactions.
Instruct patients that hearing loss can occur with the use of itraconazole. The hearing loss usually resolves when treatment is stopped, but can persist in some patients. Advise patients to discontinue therapy and inform their physicians if any hearing loss symptoms occur.
Instruct patients that dizziness or blurred/double vision can sometimes occur with itraconazole. Advise patients that if they experience these events, they should not drive or use machines.
