fluconazole, Diflucan (cont.)

Pharmacy Author:
Medical and Pharmacy Editor:

Fluconazole may increase the concentration of warfarin (Coumadin) in blood by reducing the elimination of warfarin. Therefore, the effect of warfarin may increase, leading to an increased tendency to bleed. Fluconazole also increases the concentration in the blood of phenytoin (Dilantin), cyclosporine, zidovudine (Retrovir), saquinavir (Invirase), (theophylline (Theo-Dur, Respbid, Slo-Bid, Theo-24, Theolair, Uniphyl, Slo-Phyllin), tolbutamide, glyburide (Micronase, Diabeta, Glynase), glipizide, triazolam (Glucotrol), midazolam (Versed), celecoxib (Celebrex), fentanyl (Sublimaze), atorvastatin (Lipitor), simvastatin (Zocor), and lovastatin (Mevacor). As a result, the risk of side effects from these drugs may increase.

Combining fluconazole with amiodarone (Cordarone), pimozide (Orap), bepridil (Vascor) or other drugs that affect heart rhythm may increase the risk of abnormal heart rhythms.

PREGNANCY: There are no adequate studies in pregnant women. There are reports of harmful effects to the fetus when high dose fluconazole was administered to pregnant women for a few months. Use of fluconazole during pregnancy is not recommended.

NURSING MOTHERS: Fluconazole is secreted in breast milk at concentrations similar to the mother's blood level. However, fluconazole is used for treating neonates with fungal infections and for treating lactation associated Candida infections. Available evidence suggests that use of fluconazole during breastfeeding has little risk.
