Fluconazole is an antifungal medication primarily used to treat infections caused by Candida species, including vaginal yeast infections, thrush, and systemic fungal infections. It works by inhibiting the growth of fungi, providing relief from symptoms and preventing the spread of the infection. Fluconazole is often prescribed due to its efficacy and oral administration form, making it a convenient option for patients. It is important to follow the healthcare provider’s dosage recommendations to avoid side effects and potential drug interactions.
