Itraconazole is an antifungal medication used to treat serious fungal or yeast infections. The recommended dose and duration of treatment depend on the type and severity of the infection. Here are some dosing guidelines for different types of infections:
-
Oropharyngeal or esophageal candidiasis: Itraconazole oral solution is used to treat these infections. The recommended dose is 200 mg (10 mL) once daily for 1 to 2 weeks.
-
Fungal infections: Itraconazole capsule is used to treat fungal infections such as aspergillosis, blastomycosis, or histoplasmosis. The recommended dose is 200 mg (2 capsules) once daily for 2 to 7 months.
-
Onychomycosis: Itraconazole tablet or Sporanox capsule is used to treat fungal infection in the fingernails or toenails. The recommended dose is 200 mg (2 tablets or capsules) once daily for 12 weeks.
It is important to take itraconazole exactly as prescribed by your doctor. Do not take more or less of it or take it more often than prescribed. If you miss a dose, take it as soon as possible. However, if it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not double doses.
Itraconazole may interact with other medications, so it is important to inform your doctor of all medications you are taking. Some medications, such as colchicine, fesoterodine, solifenacin, or telithromycin, should not be used during and 2 weeks after treatment with itraconazole, especially if you have kidney or liver disease.
Common side effects of itraconazole include nausea, vomiting, diarrhea, stomach pain, headache, dizziness, and skin rash. If you experience any of the following symptoms, stop taking itraconazole and call your doctor immediately or get emergency medical treatment: excessive tiredness, loss of appetite, nausea, vomiting, yellowing of the skin or eyes, dark urine, pale stools, hearing loss, blistering or peeling skin, or feelings of numbness, tingling, pricking, burning, or creeping on the skin.
