  • Finasteride is given by mouth and is used off-label to treat benign prostatic hypertrophy (enlarged prostate) in intact male dogs, and may also be used for adrenal problems in ferrets. Give as directed. Side effects are uncommon. Do not use it in sexually developing animals or in females, including pregnant or nursing females. If a negative reaction occurs, please call your veterinarian.

  • Flea infestation is a common problem in pet ferrets, especially in ferrets that go outdoors or live in a house with dogs, cats, or other animals who have fleas. Affected ferrets may or may not be itchy, depending on their sensitivity to flea bites. Signs and treatment of fleas are discussed.

  • Fleas in hedgehogs are less commonly seen in comparison to cats and dogs but a similar treatment protocol under the direction of your veterinarian is required in order to control an infestation. This handout describes the clinical signs of fleas in hedgehogs and what to do (and what not to do) if your hedgehog is affected.

  • Rabbits can become infested with fleas, especially if they go outside or live in a house with other pets that have fleas. Rabbits with fleas may show no signs or may bite, lick, or scratch themselves. Young rabbits with heavy infestations may become anemic. There are no rabbit-specific drugs for managing fleas. Certain topical anti-parasite medications appear to be safe but should only be used under the guidance of a veterinarian familiar with rabbits.

  • Fluconazole is an antifungal medication used off label in cats, dogs, and small mammals to treat fungal infections, especially those in the brain and spinal cord. It is given by mouth in the form of a tablet or liquid suspension and is also available as an injection for hospital use. It should be used with caution in pets with liver or kidney disease, or pregnant or lactating pets.

  • Fludrocortisone acetate is given by mouth and is used off label to treat hypoadrenocorticism (Addison’s disease) and hyperkalemia. Give as directed by your veterinarian. Side effects are uncommon but may include vomiting. Do not use in pets that are allergic to it or in lactating pets without using a milk replacer. If a negative reaction occurs, please call your veterinary office.

  • Fluralaner is given by mouth or applied topically and is used to treat flea and tick infestations, and also off-label to treat certain types of mange and mites. Give as directed. Side effects are uncommon but may include stomach upset or neurologic symptoms. Do not use in pets with a history of seizures. If a negative reaction occurs, please call the veterinary office.

  • Furosemide is given by mouth or injection and is used on and off label to treat many conditions, including congestive heart failure and fluid retention. Common side effects include increased urination, diarrhea, or constipation. Do not use in pets that are allergic to it or in those that are unable to make urine.

  • Ferrets can be affected by a variety of conditions causing problems with the stomach and intestinal tract. Certain bacteria may cause diarrhea or gastritis. Intestinal foreign bodies often cause a complete blockage of the intestinal tract. Some conditions may be treated with medication while others require surgical intervention.

  • Rabbits that are not eating may have developed gastrointestinal (GI) stasis. GI stasis may be caused by a physiologic change in bacteria or by one of several other conditions such as E. cuniculi. Supportive treatment either in or out of the hospital will be prescribed for a rabbit with GI stasis. Prevention steps are discussed. Have your rabbit checked regularly by a veterinarian who can monitor for the occurrence of other underlying diseases that may contribute to the development of GI stasis.
