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.
For: Cats and Dogs
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.
Dosage & Administration: Give fluconazole exactly as it was prescribed by your veterinarian. Do not give in larger amounts or use it for longer than recommended by your veterinarian. Follow the instructions on the prescription label. If you do not understand these directions speak to your pharmacist or veterinarian. Your veterinarian may want to perform blood tests on a regular basis to make sure the medication is not causing harmful effects. Store fluconazole at controlled room temperature 68°-77° F.
Tips: You may not notice a visible improvement until you've been treating your pet for 1 to 2 weeks, and you may need to treat your pet with fluconazole for several months. Make sure you continue giving the prescription to your pet until the end of the treatment regimen unless your veterinarian specifically directs you to discontinue giving fluconazole. Your pet may feel better, and you may notice an improvement in visible fungal infections before the treatment has ended, but it's important to complete the treatment to prevent a relapse and to prevent the possibility of future resistance to fluconazole or other antifungal medications.
What happens if I miss a dose: Give the missed dose as soon as you remember. However, if it almost time for the next regularly scheduled dose, skip the missed dose and give the next one as directed. Do not give a double dose of the medication.
What happens if I overdose the pet: Seek emergency veterinary medical attention if you think you have used too much of this medication. Symptoms of overdose may include loss of appetite, vomiting, jaundice, depression, tiredness, anemia, or a skin rash.
What should I avoid while using Fluconazole: Do not use fluconazole in animals with liver disease. Use with caution in animal's with kidney disease. Do not use in pregnant animals unless the benefit outweighs the risk.
Possible side effects of Fluconazole: Seek emergency veterinary medical attention if your pet experiences any signs of an allergic reaction (hives; difficulty breathing; swelling of the face, lips, tongue, or throat). Talk to your veterinarian immediately if your pet develops any of these side effects: jaundice, loss of appetite, vomiting, depression, tiredness, anemia, skin rash. Talk to your veterinarian about any side effect that seems unusual or that is especially bothersome to your pet.
What other drugs will affect Fluconazole: Tell your veterinarian if your pet is using any of the following medications: Buspirone, cisapride, cyclophosphamide, cyclosporine, thiazide diuretics (Dyazide, Diuril), NSAIDS (Rimadyl, Novox), theophylline/aminophylline, tricyclic antidepressants (clomipramine, Clomicalm, amitriptylline), sulfonylurea antidiabetics (glipizide, glyburide), warfarin (Coumadin). There may be other drugs not listed that can affect fluconazole. Tell your veterinarian about all prescription and non-prescription (OTC) medications, including vitamins, minerals, herbal products, and drugs prescribed by other veterinarians. Do not start using a new medication without telling your veterinarian.
What should I discuss with my veterinarian before using Fluconazole: Do not give this medication if your pet is allergic to fluconazole or other azole antifungal agents.

Cautions: 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.
