Noxafil (posaconazole) is a prescription triazole antifungal used to prevent invasive Aspergillus and Candida infections in immunocompromised patients and to treat oropharyngeal candidiasis. It is also used off-label for other serious mold and yeast infections.

Posaconazole works by blocking the fungal enzyme lanosterol 14-alpha-demethylase. This enzyme is essential for producing ergosterol, a key component of the fungal cell membrane. Without ergosterol, the fungal cell membrane becomes unstable and the organism cannot survive or replicate.

Noxafil has broad-spectrum activity against Aspergillus species, Candida species, Fusarium, Zygomycetes (Mucor, Rhizopus), and several other clinically important molds and yeasts. Its wide coverage makes it particularly valuable in immunocompromised patients who face multiple fungal threats.

Yes. Posaconazole is a strong inhibitor of the CYP3A4 enzyme and can significantly increase blood levels of many medications, including certain immunosuppressants like tacrolimus and cyclosporine, some chemotherapy agents, and HMG-CoA reductase inhibitors. A thorough medication review is essential before starting Noxafil.

Noxafil oral suspension should be taken with a full meal or a liquid nutritional supplement to maximize absorption. The delayed-release tablets and intravenous formulation do not have this food requirement. Your physician will specify the appropriate formulation and dosing schedule for your situation.

Patients on Noxafil should have liver function tests monitored periodically, as hepatotoxicity can occur. Electrocardiogram monitoring may be appropriate for patients at risk for QT prolongation. Blood levels of co-administered medications like cyclosporine or tacrolimus should also be watched closely due to drug interactions.
