Hepatic and renal impairment. Pregnancy and lactation. Patient Counselling May impair ability to drive or operate machinery. Avoid intense or prolonged exposure to direct sunlight. Monitoring Parameters Monitor hepatic (prior and during treatment) and renal (during treatment) function, serum electrolytes, visual and pancreatic function.
Lactation: Not known if excreted in breast milk, a decision should be made whether to discontinue nursing or drug; weigh risk/benefit
Pregnancy-Lactation
Pregnancy
Therapy can cause fetal harm when administered to a pregnant woman; there are no available data on pregnant women; in animal reproduction studies, oral voriconazole was teratogenic in rats and embryotoxic in rabbits; if this drug used during pregnancy, or if patient becomes pregnant while taking drug, inform patient of potential hazard to fetus Lactation No data are available regarding presence of drug in human milk, the effects of voriconazole on breastfed infant, or on milk production; developmental and health benefits of breastfeeding should be considered along with mother’s clinical need for therapy and any potential adverse effects on breastfed child or from underlying maternal condition
Contraception
Advise females of reproductive potential to use effective contraception during treatment
Lactation
No data are available regarding presence of drug in human milk, the effects of voriconazole on breastfed infant, or on milk production; developmental and health benefits of breastfeeding should be considered along with mother’s clinical need for therapy and any potential adverse effects on breastfed child or from underlying maternal condition
Interactions
Increased prothrombin time w/ oral anticoagulants. May increase plasma concentrations of ciclosporin and tacrolimus, long-acting opiates (e.g. oxycodone, methadone), NSAIDs (e.g. ibuprofen, diclofenac), omeprazole, short-acting opiates (e.g. alfentanil, fentanyl). Decreased voriconazole plasma concentration and increased phenytoin plasma concentrations when used concomitantly. May increase plasma concentration w/ oral contraceptives.

May increase risk of ergotism w/ ergot alkaloids (e.g. ergotamine and dihydroergotamine). May significantly increase plasma concentrations of sirolimus. Decreased plasma concentrations w/ rifampicin, carbamazepine, long-acting barbiturates (e.g. phenobarbital, mephobarbital), efavirenz (?400 mg once daily), ritonavir (?400 mg bid). Concomitant use may significantly increase rifabutin and decrease voriconazole plasma concentration.
