Dose sourceEgyptian National Drug Formulary - Antimicrobial 2023 (itraconazole monograph)
Why16 live products. The formulary lists oropharyngeal and oesophageal candidiasis as an indication and reserves itraconazole for fluconazole-refractory disease - the option to reach for when nystatin and fluconazole have not worked.
Cautions- Reserve for fluconazole-refractory disease - the formulary says so explicitly.
- The formulary does NOT recommend the capsule for candidiasis; the oral solution is better absorbed. Most Egyptian products are capsules, so absorption is the main reason treatment fails.
- Capsules need stomach acid and food - do not co-prescribe with a PPI or H2 blocker.
- Itraconazole is a strong CYP3A4 inhibitor: check statins (simvastatin is contraindicated), DOACs, calcium channel blockers, vardenafil, and ergot derivatives before prescribing.
- Hepatotoxicity can occur - stop for nausea, anorexia, dark urine or jaundice, and check liver enzymes.
- Recurrent oral thrush in an adult with no inhaled steroid or denture cause needs an HIV and diabetes check, not a stronger antifungal.
- Use with caution in patients with risk factors for heart failure.
- Use with caution in patients with risk factors for heart failure (COPD, renal failure, edematous disorders, ischemic or valvular disease).
