Whether a fungal infection can be cured by taking only itraconazole should depend on the type of fungus and the degree of infection. Itraconazole is a broad-spectrum antifungal drug that usually has a good curative effect in the treatment of fungal infections, such as vulvovaginal candidiasis, fungal keratitis, oral candidiasis, and sporotrichosis. However, itraconazole alone may not be effective if combined with other types of infections (e.g. bacterial infections, etc.) or if the infection is more severe. Itraconazole is usually indicated in gynecology, dermatology, ophthalmology or systemic fungal infections. 1. Gynecology: usually indicated for vulvovaginal candidiasis. 2. Dermatology: usually indicated for lichen planus and skin fungal diseases. 3. Ophthalmology or stomatology: usually for fungal keratitis, oral candidiasis, etc. 4. Systemic fungal infections: usually for systemic aspergillosis and candidiasis, histoplasmosis, sporotrichosis, cryptococcosis, etc. Itraconazole may cause adverse reactions such as liver abnormalities, gastrointestinal discomfort, headache, menstrual disorders and drug rash. It is contraindicated for those who are allergic to this drug and pregnant women. Fungal infectious diseases should be applied under the guidance of a professional physician, such as antifungal drugs, not self-medication, in order to avoid serious adverse reactions.
