Ketoconazole 200mg tablets are an antifungal medication used to treat various fungal infections, including those affecting the skin, nails, and internal organs. It works by inhibiting the growth of fungi and preventing them from producing essential components of their cell membranes. This helps to control and eliminate the infection. Ketoconazole is typically taken orally once daily with food to improve absorption. Common side effects may include nausea, headache, and abdominal pain. It’s important to follow your doctor’s instructions regarding dosage and duration of treatment to ensure the infection is fully treated. Regular monitoring may be required to check for potential liver-related side effects.
