Voriconazole is an azole antifungal drug. It inhibits the fungal cytochrome P-450 mediated 14 alpha-lanosterol demethylation, an essential step in fungal ergosterol biosynthesis. The accumulation of 14 alpha-methyl sterols correlate with the subsequent loss of ergosterol in the fungal cell wall and may be responsible for the antifungal activity of voriconazole.

    • Hypersensitivity to voriconazole or its excipients.
    • Coadministration with cisapride, pimozide or quinidine, sirolimus due to risk of serious adverse reactions.
    • Coadministration with rifampin, carbamazepine, long-acting barbiturates, efavirenz, ritonavir, rifabutin, ergot alkaloids and St. John's Wort due to risk of loss of efficacy

Warning & Precautions

    • Hepatic Toxicity: Serious hepatic reactions reported. Evaluate liver function tests at start of and during Voriconazole therapy.
    • Arrhythmias and QT Prolongation: Correct potassium, magnesium and calcium prior to use; caution patients with proarrhythmic conditions.
    • Visual Disturbances (including optic neuritis and papilledema): Monitor visual function if treatment continues beyond 28 days.
    • Photosensitivity: Avoid sunlight due to risk of photosensitivity.
    • Patients with Hereditary Galactose Intolerance, Lapp Lactase Deficiency or Glucose-Galactose
      Malabsorption: Voriconazole tablets should not be given to these patients because it contains lactose.

    The most common side effects may include visual disturbances, fever, nausea, rash, vomiting, chills, headache, liver function test abnormal, tachycardia, hallucinations, pyrexia, epistaxis, abdominal pain, diarrhea, hypokalemia, cough, thrombocytopenia, peripheral edema, hyperglycemia, dyspnea, hypocalcemia, hypophosphatemia, LFT abnormal, mucosal inflammation, photophobia, abdominal distention, constipation, dizziness, hemoptysis, hypoalbuminemia, hypomagnesemia, renal impairment, upper respiratory tract infection etc.

Drug interaction

    • CYP3A4, CYP2C9, and CYP2C19 inhibitors and inducers: Adjust voriconazole dosage and monitor for adverse reactions or lack of efficacy.
    • Voriconazole may increase the concentrations and activity of drugs that are CYP3A4, CYP2C9 and CYP2C19 substrates. Reduce dosage of these other drugs and monitor for adverse reactions.
    • Phenytoin or Efavirenz: with co-administration, increase maintenance oral and intravenous dosage of voriconazole.

Use in special groups

    • Pregnancy: Voriconazole can cause fetal harm when administered to a pregnant woman. There are no available data on the use of Voriconazole in pregnant women.
    • Lactation: No data are available regarding the presence of Voriconazole in human milk, the effects of Voriconazole on the breastfed infant, or the effects on milk production.
    • Pediatrics: Safety and effectiveness in patients younger than 2 years has not been established.
    • Geriatric Use: Overall safety profile of the elderly patients is similar to that of the young so no dosage adjustment is recommended.
    • Hepatic Impairment: Use half the maintenance dose in adult patients with mild to moderate hepatic impairment (Child-Pugh Class A and B).
    • Renal Impairment: No dose adjustment is necessary for oral dosing in patients with mild to severe renal impairment.
