Insights

Serious convulsions may occur in patients receiving high-dose fluconazole if serum trough concentrations exceed 80 microg/mL. Monitoring is recommended for patients with impaired kidney function during high-dose fluconazole therapy.

Area of Science:

  • Pharmacology
  • Clinical Neurology

Background:

  • Fluconazole is a widely used antifungal medication.
  • High-dose therapy is sometimes necessary for severe fungal infections.

Observation:

  • Two case reports suggest a link between fluconazole and serious convulsions.
  • This association was observed when serum trough concentrations surpassed 80 microg/mL.

Findings:

  • Elevated serum trough concentrations of fluconazole ( > 80 microg/mL) may precipitate serious convulsions.
  • Patient factors, such as impaired kidney function, might influence fluconazole accumulation.

Implications:

  • Clinicians should consider monitoring fluconazole serum levels in patients receiving high-dose treatment, especially those with renal impairment.
  • This monitoring may help prevent adverse neurological events like seizures.
  • Further research is warranted to confirm this association and establish clear therapeutic drug monitoring guidelines.
