Sporanox contains itraconazole as its active ingredient. Itraconazole is an antifungal agent used to treat a variety of fungal infections. The medication is supplied as a 100 mg pill and is available by prescription in Hong Kong.
The drug is regulated by the Hong Kong Department of Health and, like most prescription medicines, requires a healthcare-provider’s authorization before use.
Itraconazole belongs to the triazole class of antifungals. It works by inhibiting the fungal enzyme lanosterol 14α-demethylase, which is essential for converting lanosterol to ergosterol, a key component of the fungal cell membrane.
Sporanox is approved in Hong Kong for the treatment of the following fungal infections:
These indications are based on regulatory approvals and clinical guidelines for itraconazole therapy.
Evidence from peer-reviewed studies suggests itraconazole may be used off-label for:
Off-label use requires medical supervision and individualized risk assessment.
These reactions are usually transient and improve with continued therapy or simple supportive measures (e.g., taking the pill with food).
If any signs of liver injury (jaundice, dark urine) or severe cardiac symptoms occur, seek medical attention immediately.
Major interactions:
CYP3A4 inhibitors (e.g., ketoconazole, clarithromycin, ritonavir) can increase itraconazole levels and risk toxicity.
CYP3A4 inducers (e.g., rifampin, carbamazepine, St. John’s wort) can reduce efficacy.
Anticoagulants such as warfarin - monitor INR closely.
Moderate interactions:
Statins (e.g., simvastatin) - increased risk of myopathy; consider dose adjustment.
Digoxin - higher plasma concentrations possible.
Patients should provide a complete medication list, including over-the-counter products and herbal supplements, to their healthcare provider.

Itraconazole can increase the blood levels of certain statins (e.g., simvastatin) because both are metabolized by CYP3A4. Your prescriber may lower the statin dose or choose an alternative that is less likely to interact.
Nail infections often require several months of therapy-typically 12 weeks for the nail matrix to grow out completely. Clinical improvement may be seen earlier, but full clearance usually follows the nail’s natural growth cycle.
Mild to moderate hepatic impairment does not automatically preclude use, but liver enzymes should be monitored regularly. The dose may need adjustment based on test results and clinical judgment.
Dairy itself does not affect itraconazole absorption, but antacids containing calcium carbonate can reduce bioavailability. Separate antacid dosing by at least 2 hours from the pill.
Take the missed dose as soon as you remember unless it is less than 4 hours before the next scheduled dose. In that case, skip the missed dose and continue with the regular schedule; do not double the dose.
Photosensitivity is not a common side effect of itraconazole, but any rash that worsens with sun exposure should be reported to a healthcare professional.
Yes, itraconazole is available as a generic medication in tablet form. The generic contains the same active ingredient and strength (100 mg) but may have different inactive components.
Itraconazole can increase estrogen levels by inhibiting CYP3A4, potentially enhancing contraceptive effectiveness. However, no significant reduction in contraceptive efficacy has been documented. Continue using your chosen method as directed.
Yes, but keep the medication in its original packaging with the prescription label, carry a copy of the prescription, and be aware of any import restrictions for controlled substances in the destination country.
Itraconazole (Sporanox) has a broader spectrum against dermatophytes and certain molds, while fluconazole is more active against Candida species and has better central nervous system penetration. Choice of agent depends on the specific fungus and infection site.
