minor Known Drug Interaction
Although clinical studies have not been performed, based on the involvement of the cytochrome P-450 3A family in clonazepam metabolism, inhibitors of this enzyme system, notably oral antifungal agents (e.g., fluconazole), should be used cautiously in patients receiving clonazepam because they may impair the metabolism of clonazepam leading to exaggerated concentrations and effects.
Recommendation: Use this combination carefully. Your doctor should monitor you for increased side effects like extreme sleepiness.

Fluconazole can also treat urinary tract infections, peritonitis, systemic Candida infections, and pneumonia. It can also treat cryptococcal meningitis. Fluconazole can also prevent candidiasis in patients undergoing bone marrow transplantation.
Clonazepam works by affecting chemicals in your brain that may be unbalanced. It enhances the effects of a natural brain chemical called GABA. This helps to reduce seizures and relieve panic symptoms.
