Fluoxetine Side Effects in Dogs

Fluoxetine, perhaps better known by its brand name, Prozac, is a tricyclic antidepressant prescribed in dogs to treat compulsive behaviors, aggressive behaviors, anxiety and fear. It can be prescribed as well to treat allergic skin disorders that do not respond to other therapies.

Function

Fluoxetine works by increasing the levels of Serotonin in the brain. This chemical is responsible for creating a sense of well-being and sending out more effectively messages among brain cells.

Considerations

Fluoxetine is to be administered strictly under the supervision and guidance of a licensed veterinarian and as with any medication, even though effective, it has the potential of causing side effects and complications.

Side Effects

Fluoxetine may cause drowsiness, lethargy, episodes of panting, restlessness, shaking, vocalization, aggression, loss of appetite, vomiting and diarrhea (especially when given on an empty stomach) and in cases of overdose, seizures.

Warning

Fluoxetine should not be prescribed in dogs affected by liver disease, heart arrhythmias, heart failure, kidney failure, hyperthyroidism, glaucoma, seizures, or dogs on thyroid medication. The drug should not be used as well in pregnant dogs, puppies or senior dogs with specific health problems.

Misconceptions

Fluoxetine is not a miracle drug that will bring a dog with psychological and behavior problems back to normal. In order for therapy with Fluoxetine to effectively work, behavior modification strategies and environmental changes should take place as well. Therapy with Fluoxetine should never be abruptly stopped to prevent relapses.
