Interacting drugs- summary
+ Fluconazole
Cimetidine
fluconazole plasma levels reduced, possibly due to decreased absorption
Hydrochlorthiazide
concomittant use resulted in significant increase in fluconazole Cmax
and AUC which can be attributed to reduced renal clearance
Rifampin
a single oral fluconazole dose after chronic rifampin resulted in decrease
in AUC and a shorter half-life of fluconazole
Fluconazole +
Antihistamines Non sedating
although terfenadine levels were not affected by fluconazole, terfenadine
metabolite AUC increased
Contraceptives Oral
concurrent use with an OC containing ethinyl estradioal/levenogestrel
produced an overall mean increase in the levels of the OC components
Cyclosporine
significant increases in cyclosporine Cmax, Cmin.and AUC values occurred
following use.
Phenytoin
coadministration resulted in an increase of phenytoin AUC values
Theophylline
theophylline AUC , Cmax, and half-life were significantly increased and
clearance was decreased
Sulfonylureas
Fluconazole resulted in significant increases in Cmax and AUC of
tolbutamide, glyburide, and glipizide. Several subjects experienced
symptoms with hypoglycemia, requiring oral glucose treatment
Warfarin
a single warfarin dose of fluconazole resulted in an increase
in the PT response (area under the prothombin time-time curve).
Zidovudine
there was a significant increase in zidovudine AUC following fluconazole
administration

Warnings-
Causative organisms- obtain specimen for fungal culture and other relevant laboratories studies ( seriology, histopathology) prior to therapy and identify causative organisms. Therapy may be instituted before the results are known, however, once the results become avilable, adjust anti-infective therapy accordingly.
Hepatic injury-
Fluconazole has been associated with rare cases of serious hepatic injury. Patients who develop abnormal liver function tests during fluconazole therapy should be monitored for development of more severe hepatic injury.
Fluconazole should be discontinued if clinical signs and symptoms consistent with liver disease develop that may be attributable to fluconazole.
Anaphylaxis- in rare cases, anphylaxis has occurred.
Dermatologic changes- patients have rarely developed exfoliative skin disorders during treatment with fluconazole.
