Fluconazole is an antifungal medicine in tablet form that is used to treat a variety fungal infections, including yeast infections. It is typically used to treat skin infections, and more intense fungal infections of the lungs and other organs that can occur after your pet inhales fungus from infected soil. Fluconazole is often used in pets who have been unable to tolerate other types of antifungal medication. It is also used for difficult-to-treat fungal infections, such as those that have spread to internal organs. Fluconazole requires a prescription from your veterinarian, and is sold per tablet.
For: Cats and Dogs
Treats a variety of internal and external fungal infections
Treats serious fungal infections of the central nervous system (CNS) more effectively than many other antifungals
Has fewer side effects than most other antifungals
Is effective against ringworm
How it works:
Fluconazole is related to ketoconazole, but it is more successful in treating infections of the central nervous system (CNS) because it more effectively crosses the blood-brain barrier, allowing the medication to find its way to the infected areas of the body. When your pet takes fluconazole, the active ingredient within the medicine kills the fungus that causes infections by interfering with the cell membranes of the fungus. This inhibits growth of the fungus, which keeps the fungal cells from reproducing, and eventually eradicates the infection.
Fluconazole can interact with many other drugs. It is important to tell your veterinarian about any other medications, vitamins, or supplements your pet is taking before giving fluconazole to your pet. Do not give to pets who have liver disease or impairment. If your pet has kidney disease or kidney failure, discuss the risks versus benefits with your veterinarian before giving fluconazole. Do not give to pregnant animals or animals that are nursing unless your veterinarian says the benefits outweigh the risks. Do not give fluconazole to any pets who are sensitive or allergic to other "azole" antifungal medications, such as ketoconazole. If you have any concerns about this medication, talk with your veterinarian before giving it to your pet.

You would need to have your pet examined by a veterinarian to see what is causing the weeping. It might be dry eye, or it might be an infection or something else. If it is an infection, your veterinarian will prescribe the appropriate antibiotic.
