Fluconazole is an azole antifungal that interferes with fungal cell membrane synthesis, making it effective for several invasive and mucosal fungal diseases.

- Candidiasis (oropharyngeal, esophageal, vaginal): Reduces fungal burden and alleviates symptoms in mucosal yeast infections. - Cryptococcal meningitis: Provides systemic antifungal activity to treat central nervous system infection caused by Cryptococcus species. - Systemic fungal infections: Acts against a broad range of pathogenic yeasts and molds in disseminated disease.

Fluconazole may cause a range of adverse reactions, varying from mild to severe.

Common Side Effects: - Nausea: mild stomach upset often reported. - Headache: transient cranial discomfort. - Diarrhea: loose stools that usually resolve. - Abdominal pain: cramping or discomfort in the stomach area.

Serious or Rare Side Effects: - Hepatotoxicity: elevated liver enzymes or liver injury. - Severe skin reactions: Stevens‑Johnson syndrome or toxic epidermal necrolysis. - Cardiac arrhythmias: QT prolongation leading to irregular heartbeat.

Before prescribing fluconazole, clinicians should evaluate several safety considerations to minimize risk.

- Pregnancy: Use only if benefits outweigh risks; classified Category D due to potential fetal harm. - Liver disease: Adjust therapy and monitor hepatic function in patients with pre‑existing liver impairment. - Renal impairment: Dose may need modification in severe kidney dysfunction. - Drug interactions: Review concomitant medications for potential CYP450 interactions. - Allergic reactions: Discontinue if signs of hypersensitivity such as rash or swelling appear. - Store at ambient temperature: keep below 25 °C in the original container, protect from moisture.

Fluconazole can affect the metabolism of other drugs, requiring careful management of co‑administered therapies.

Major Interactions (Avoid): - Cisapride: risk of serious cardiac arrhythmias. - Pimozide: may cause QT prolongation and arrhythmias. - Certain statins (e.g., lovastatin, simvastatin): increased risk of myopathy.

Moderate Interactions (Monitor Closely): - Warfarin: fluconazole can increase INR, requiring dose adjustment. - Phenytoin: may reduce fluconazole levels, decreasing efficacy. - Oral contraceptives: may decrease hormonal effectiveness, consider backup contraception.
