Answer

Oral itraconazole in doses of 100 mg/d for 2 weeks shows high efficacy. With an increased dose of 200 mg/d, the treatment duration can be reduced to 1 week. However, the cytochrome P-450 activity of itraconazole allows for potential interactions with other commonly prescribed drugs. [34] When it is appropriate to prescribe the drug, there may be some advantage to giving itraconazole with whole milk to increase absorption. [35]
