This article contains information about fluconazole for dogs, including the correct dosage, side effects, how to safely use the medicine and more.

Fluconazole, also marketed as “Diflucan”, is a medicine sometimes used for the treatment of yeast and fungal infections, especially when other anti-fungal drugs are not well tolerated by your pet. Aside from just treating common fungus on the skin, it can also treat more aggressive forms of infection which is affecting internal organs. It is similar to ketoconazole for dogs except it has the ability to cross the blood-brain barrier. Fluconazole is a prescription drug which should never be given to your dog without explicit permission and approval from a vet.

Fluconazole dosage for dogs

The dosage range of fluconazole is very large, and is highly dependent on the severity of your pet’s infection and medical history. The recommended dose of fluconazole for dogs is 5.5 – 22 mg/lb body weight administered once daily. Your vet may also suggest administering the medication twice a day.

Always follow the specific instructions given to you by your vet when using this medication.

Is fluconazole safe for dogs?

Fluconazole is safe for use in dogs, though failing to follow safety recommendations could lead to severe side effects. It’s important to read the safety information below and listen to the advice of your vet before giving your dog fluconazole.

Safety precautions

  • Avoid use in pregnant dogs or dogs with liver disease
  • Notify the vet and practice extra care if your dog is diabetic, lactating or if he/she suffers with kidney disease
  • Never mix with cyclosporine, amphotericin B, rifampicin or hydrochlorothisazide
  • Notify the vet of any other medication your dog is taking
  • Notify the vet if your dog has had allergic reactions to anti-fungal medicine in the past

Complete the full course of medicine outlined by your vet. Never increase the dosage or administer the drug for a period of time longer than what was advised by the vet. Dogs suffering with diabetes or any kind of liver/kidney disease are at a heightened risk of developing adverse side effects as a result of the drug. Use in dogs with liver disease is very rarely advised by professionals and should be avoided in most cases.
