Itraconazole belongs to the family of medications called antifungals. It is used to treat certain types of fungal infections, both internally (inside the body) and externally (skin and nails). It works by preventing the fungus from growing.
Itraconazole solution is used specifically for treatment of fungus (candidiasis) occurring in the mouth or esophagus (the tube leading from the throat to the opening of the stomach) in people infected with HIV or in people whose natural defences against infections are depleted.
Capsules: The recommended adult dose of itraconazole capsules ranges from 100 mg once daily after a full meal to 200 mg twice daily after meals, depending on the condition being treated. The length of treatment also depends on the condition being treated. Itraconazole capsules should be taken right after a full meal. Itraconazole capsules must be swallowed whole. Grapefruit juice may reduce the effectiveness of itraconazole.
