I have toenail fungus and nail fungus, my dermatologist had mentioned putting me on fluconazole if it got worse, it has spread. Would I be a candidate for this drug since i am on the fentanyl patch for intractable chronic migraines. I also take lyrica, topamax , clonazapam and lexapro. i have tried laser therapy and it still has not gotten any better, would there be any drug interactions with the fluconazole? I appreciate your response.
