 Indications Treatment of invasive aspergillosis; treatment of Scedosporium apiospermum and Fusarium spp., including Fusarium solani, in patients intolerant of or refractory to, other therapy.

 Contraindications Hypersensitivity to voriconazole or any of it excipients, coadministration of carbamazepine, cisapride, ergot derivatives (eg, ergotamine, dihydroergotamine), long-acting barbiturates, pimozide, quinidine, rifabutin, rifampin, sirolimus.

 Route/Dosage

ADULTS AND CHILDREN (12 yr and older): IV Loading dose of 6 mg/kg q 12 hr for 2 doses, followed by a maintenance dose of 4 mg/kg q 12 hr. If patients are unable to tolerate treatment, reduce the IV maintenance dose to 3 mg/kg q 12 hr.

ADULTS AND CHILDREN (12 yr and older): PO Once an oral dose can be tolerated, patients weighing more than 40 kg should receive 200 mg q 12 hr. If response is inadequate, the oral dose may be increased to 300 mg q 12 hr. If patients are unable to tolerate oral treatment, reduce the oral dose by 50 mg increments to a min of 200 mg q 12 hr. Patients weighing less than 40 kg should receive 100 mg q 12 hr. If the response is inadequate, the oral dose may be increased to 150 mg q 12 hr. If patients weighing less than 40 kg are unable to tolerate oral treatment, reduce the oral dose by 50 mg increments to a min of 100 mg q 12 hr.

Hepatic Insufficiency: ADULTS AND CHILDREN (12 yr and older): IV or PO It is recommended that the standard loading dose regimens be used but that the maintenance dose be halved in patients with mild to moderate hepatic cirrhosis.

 Interactions

Benzodiazepines (eg, alprazolam), cyclosporine, dihydropyridine calcium channel blockers (eg, felodipine), HMG-CoA reductase inhibitors (eg, lovastatin), NNRT (eg, efavirenz), omeprazole, phenytoin, protease inhibitors (eg, ritonavir), sulfonylurea hypoglycemic agents (eg, glipizide), tacrolimus, vinca alkaloids (eg, vinblastine), warfarin: Plasma exposure to these agents may be increased by voriconazole, increasing the pharmacologic and adverse effects. Carbamazepine, cisapride, ergot derivatives (eg, ergotamine, dihydroergotamine), long-acting barbiturates, pimozide, quinidine, rifabutin, rifampin, sirolimus: Coadministration of these agents with voriconazole is contraindicated. Non-nucleoside reverse transcriptase (NNRT) inhibitors (eg, efavirenz), phenytoin: May decrease voriconazole plasma levels, reducing the pharmacologic effect. NNRT inhibitors (eg, efavirenz), Protease inhibitors (eg, ritonavir): May elevate voriconazole plasma levels, increasing the pharmacologic and adverse effect.

Aminofusin 10%. Do not infuse voriconazole into the same line or cannula with other drug infusions, including parenteral nutrition; do not infuse with blood products or electrolyte supplementations; do not dilute with 4.2% sodium bicarbonate infusion.
