Is Prozac For Dogs Fda Approved

How do antidepressants work? – Neil R. Jeyasingam

Yes, fluoxetine has been approved on label for dogs for the treatment of separation anxiety. However, in other forms of behavioral modification, Prozac will be off label, meaning the FDA has not approved it for this reason.

Veterinarians will commonly prescribe medicines off label, including fluoxetine. Still, it is essential to understand any risks associated with doing this and make sure to follow your veterinarians advice closely and look for possible side effects of the medicine.

According To Our Experts Some Drawbacks Of Using Prozac Can Be:

  • Takes about four to six weeks to work.
  • May cause side effects in some dogs .
  • Can come with a stigma associated with giving Prozac to pets.
  • If you tell someone your dog is taking Prozac, its not uncommon to get a raised eyebrow, experts say.

    The stigma is that many people think its unconscionable to give human psychoactive medication to a dog, Dodman says. They clearly do not understand that it can be life-saving. The same people may shun that kind of medicine themselves, again, for no good reason.

    4. Could theoretically carry the risk of overdose, although extremely difficult, according to Dodman.

    is a very safe drug, far safer than a lot of other medications that people take without qualms, Dodman says. It is true, though, that if you take two serotonin medications together at high doses, the so-called serotonin syndrome theoretically could be triggered.

    Serotonin syndrome is the accumulation of too much of the serotonin chemical in the body, and symptoms include fever, muscle twitching, convulsions and more.

    I have never seen it, and Ive never heard of it being reported in the vet literature, but it is a theoretical possibility, Dodman says.

    Precautions And Side Effects

    • While generally safe and effective when prescribed by a veterinarian, fluoxetine can cause side effects in some animals.
    • Fluoxetine should not be used in animals with known hypersensitivity or allergy to the drug. Fluoxetine is contraindicated in animals with a history of seizures.
    • Fluoxetine may interact with other medications. Consult with your veterinarian to determine if other drugs your pet is receiving could interact with fluoxetine. Such drugs include drugs classified as monoamine oxidase inhibitors , diazepam, phenylbutazone, digoxin or buspirone.
    • Side effects associated with fluoxetine include lethargy, panting, hyperactivity, shaking, restlessness, excessive vocalization, aggression and temporary lack of appetite. Gastrointestinal upset may also occur.
    • When large quantities of fluoxetine are ingested, pets may seizure. Overdose should be promptly treated by your veterinarian.

    Prozac For Anxiety In Dogs

    Just like humans, dogs each have their own temperament and unique personalities. Some dogs are more rambunctious than others. There are dogs that prefer spending time around others, while others prefer their alone time. For some dogs, being home alone for several hours a day doesnt bother them. Then, there are dogs who experience separation anxiety when apart from their owners for any stretch of time.

    When dogs experience separation anxiety or other anxiety-related disorders, its not uncommon for them to act out. They may bark constantly, have urinating accidents in the house, or show their anxiety in other ways, like tearing up household items or chewing on the furniture. At first, these actions may seem like ones of a misbehaved pet, but there may be deeper issues leading to these actions.

    If your dog suffers from separation anxiety and your lifestyle doesnt allow you to be home throughout the day, Prozac may be prescribed by your veterinarian to help alleviate the problem. It helps to slow down the metabolism of serotonin in your dogs brain. Serotonin helps to regulate feelings of anxiety and promote feelings of happiness. When its able to stick around longer, it can help your dog feel less anxious.

    Depending on your dogs health history and environment, Prozac may be prescribed for daily use as treatment for separation anxiety. Or, it can be prescribed to use as needed when you are going out of town, traveling, or leaving your dog at a kennel.

    Things To Consider Beforehand

    With our furry best friends no magic bullet will quickly cure any behavioral problem. There are limitations to the use of medications which may include the following:

    • adverse effects
    • limited information on the medication use
    • possibility of a lengthy treatment plan before the medication works
    • chance that the behavior will manifest again once the medication is withdrawn.

    Most antidepressant and anti-anxiety medications used in dogs are well tolerated. But mild reactions include:

    • vomiting
    • lethargy
    • other gastrointestinal problems.

    But also some severe adverse effects, such as:

    • fatal inflammation of the liver
    • seizures
    • other signs of toxicity

    It is essential to keep in mind that using this type of medication on dogs, without combining it with behavior modification or environmental changes, may allow for the unwanted behavior to return when the drug is withdrawn.

    Most of these drugs will require use for a year or even longer. Additionally, although the medication has the potential to help with an array of behavioral problems including thunderstorm phobias and lick granulomas, pet parents need to first assess whether the symptoms their dog is presenting is instead health related.
