Itraconazole 200 mg capsules are a prescription antifungal medication used to treat a variety of fungal infections affecting the skin, nails, mouth, lungs, and other parts of the body. It works by inhibiting the growth of fungi, helping to eliminate the infection and prevent its spread. Doctors may prescribe itraconazole for conditions such as ringworm, fungal nail infections, and certain systemic fungal diseases. The dosage and duration of treatment depend on the type and severity of the infection. Patients should take the medication exactly as directed by their healthcare provider. Because itraconazole can interact with other medicines and may not be suitable for everyone, medical supervision is important. Always consult a healthcare professional before starting or stopping treatment to ensure safe and effective use.
