Itraconazole 200 mg capsules are an antifungal medicine used to treat a variety of fungal and yeast infections, including infections of the lungs, nails, mouth, throat, and skin. It belongs to the triazole class of antifungals and works by inhibiting the growth of fungi by disrupting their cell membrane formation. This allows the body’s immune system to eliminate the infection more effectively. The 200 mg capsule is commonly prescribed for moderate to severe infections or for conditions that require a higher initial dose followed by maintenance therapy. It should be taken exactly as prescribed by a healthcare professional, usually with food to improve absorption.
