As a prescription drug, Diflucan treats fungal infections. Fluconazole, the drug's principal component, is linked to other triazole antifungals including ketoconazole (Nizoral), miconazole (Micatin), clotrimazole (Lotrimin), and itraconazole (Nizoral) (Sporanox). There are two different forms of Diflucan on the market: a pill and a liquid.
Patients using Diflucan should be alert for signs of an allergic response, which include trouble swallowing, wheezing, dizziness, skin rashes, swelling or severe itching of the face, throat, or tongue. In the event of an allergic response or other severe adverse impact, patients should immediately seek medical attention.
