Fluconazole is an antifungal medication commonly used to treat infections caused by fungi and yeast. It works by inhibiting the growth of these organisms, making it effective against conditions like candidiasis and cryptococcal meningitis. Fluconazole is often prescribed in oral or intravenous forms, depending on the severity of the infection. This medication is generally well-tolerated, but some people may experience side effects such as nausea, headache, or dizziness. It is important to follow a healthcare provider's instructions when taking fluconazole to ensure proper treatment and minimize potential interactions with other medications.
