Prozac for Your Dog

A new canine version of Prozac will soon be available. It is just the latest in pet-specific drugs, as pharmaceutical companies increasingly chase this lucrative market.

Dogs on Prozac: A newly reformulated version of the popular antidepressant, made chewable and tasty for dogs, can help relieve symptoms of canine separation disorder.

Anxiety-ridden dogs that go berserk when left alone by their owners will soon have a new treatment option--a reformulated version of the antidepressant Prozac, known generically as fluoxetine. To be marketed under the name Reconcile by Indianapolis-based drugmaker Eli Lilly, the drug is chewable and flavored with a doggie-delectable zing. It is the latest in a string of recently approved canine drugs, reflecting the growing market for pet pharmaceuticals.

The U.S. Food and Drug Administration approved Reconcile in February after clinical tests in dogs showed it significantly improved symptoms of separation anxiety, a problem that strikes 10 to 20 percent of canines with varying severity; dogs affected may bark, chew household items, or urinate in inappropriate locations when left alone. The drug, which will go on the market in April and will be sold along with a behavior modification program, is the first product introduced by a new division of Lilly devoted entirely to pets.

Most drugs used for companion animals, as the pharmaceutical companies refer to pets, are human drugs that veterinarians prescribe off label. The cost of drug development is so high that few companies are willing to spend the money it takes to develop a canine-specific drug, or to run clinical trials testing human drugs for dogs or cats. But as more and more Americans view their pets as family members that is changing, and a new market is opening up: medications are being reformulated and sold in animal-friendly forms, and drugs that never quite made it through the human testing process are being revived.

"I think the human-animal bond has changed in the last few years," says Dawn Boothe, a veterinary internist and clinical pharmacologist at Auburn University in Auburn, AL. "People are starting to say, 'My animal is a member of the family, and I am willing to pay the cost of drugs that were developed for humans.' I think the pharmaceutical companies have picked up on that."

Two other pet drugs were approved early this year: the first diet drug for dogs, Slentrol, and the first motion-sickness drug for dogs, Cerenia. Both are being sold by New York-based Pfizer. Unlike Reconcile, neither drug has ever been prescribed for humans. Dirlotapide, the generic form of Slentrol, was originally tested for human use, but its side effects were deemed intolerable. (Compounds in the same class are being tested for their cholesterol- and triglyceride-reducing properties in humans.)

Veterinarians are excited about the prospect of drugs that have been tested specifically in pets. "Prozac is a drug we've used for years," says Boothe. "But having it approved in dogs gives us a level of confidence regarding safety and efficacy in that species." Although scientists have tested different drugs in cats and dogs, Boothe and others say it has been difficult to get pharmaceutical companies interested in developing them. Nicholas Dodman, an animal behaviorist and veterinarian at Tufts University in Medford, MA, says a drug currently used to treat dementia in humans is helpful in treating an animal form of obsessive-compulsive disorder, but so far no pharmaceutical company has opted to develop it for the pet market.

Lilly's companion-animal division is testing molecules from its vast library of compounds to treat obesity and other conditions in pets, a process they hope will produce some returns on the original investment in those molecules. "Even if you assume only two million of the dogs with anxiety disorder get treated," says Dodman, "with owners paying $50 per month, that's a viable market."

    How can people use that kind of dug to their pet?
    It is like that you leave your kid alone at home, and then give him/her a pile so your kid can feel better without his/her parents. How could that be so?
    Why people take more time to hang out with their pets?

    I prefer to have a virtual pet at www.chatany.com, but give my real dog a pile instead of playing with it.

    Lets see - we can start naming our dogs Elvis, Jimmy, Janis, Freddie (prinz) and Marilyn (or Anna if you prefer).

    Rather than doping up the pups, why not take them out of their cages once in a while, play with them (like Stick Chase or Tug of War), getting a play mate (most animals have social behaviors - especially dogs) and just walk them. If the drug companies need to increase market share this way -they're in the wrong business.

    I own a dog with Separation Anxiety and if someone were to actually look in to the causes of separation anxiety they might understand that for a lot of cases it has nothing to do with the amount or quality of time spent with your dog.  SOme dogs for often unknown reasons develop an unhealthy over attachment to their owners and the separation ,irrespective of the length of time, is very stressful for them. 

    There are some dogs that are left alone for too long and will bark or chew stuff out of boredom, but that is not separation anxiety. 

    Medication is not the first choice, there are behaviour modification programs that are often effective.  But what if they aren't?  The article does state that this medication is to be used in conjunction with behaviour programs. 

    There may be times that this drug will be used as an easy way to try to solve your dogs problems.  But I don't think it should be condemned because of that.

      There are plenty of herbal remedies that work well and are perfectly safe. A dogsitter is another option. If sitters are good enough for kids, they're good enough for a beloved pet.

      The problem is that the term 'separation anxiety' very often is totally misunderstood. Separation anxiety exists, but it normally has nothing in common with the described symptoms of dogs going berzerk in the absence of their owners. Dogs that suffer from separation anxiety are frightened, which results in behaviours like shiverring, extreme salivation or uncontrolled urination, but apart from that they tend to be rather quiet.

      The 'berzerks', which can easily be observed by video cameras, have a completely different motivation. They express a mixture of frustration and anger for being left alone, which in most cases is symptomatic for a conflict in the human-animal relationship. In the eyes of the dog the person must not leave the house without the dog and so the dog revolts.

      To treat these dogs with downers means complete neglection of the source of the problem.

      Emily,
      I think you made a great point about the Prozac we are considering this method for our dog. She is a pure Breed Bull Terrier. We have had her for about 12 months and she has been threw training and now we are going to look into taking her to a behaviorist. Our trainer says that she is at her teenage stage and she has to learn she cannot be the dominate alpha female but after training and training and spending time with her. I am beginning to think that she just has seperation anxiety from my husband. Sometimes she is just the happiest dog in the world and then snaps or freaks out when my boyfriend leaves. She tries to dominate everyone and it is getting out of control no matter how we approach the situation. We love our dog and we have tried so many things but now it has come down to option of possible medication. How old was your dog when you resulted to medication? Its a hard decision but I will leave it up the behaviorist. If anyone has any other suggestions I am open to hearing them.

    This may sound odd but apparently 5HT has been linked to the damage in many valve diseases and particularly some dog mitral problems. Anyone aware of any data in dogs showing that Prozac is good or bad for this? In as much as 5HT release from platelets may be involved and this seems to inhibit platelets, you could speculate it would be helpful.

    Thanks.

  • The Deadly Prozac Con

    Prozac is one of the deadliest cons ever unleashed on the public.  This drug is linked to so many murder/suicides that the public would be absolutely shocked to learn the true details of how many people have been killed by these drugs.

    Here is the ugly truth about Prozac.

    From the beginning, patients experienced psychotic and manic episodes, and made people commit suicide, but Eli Lilly covered it up by recoding and removing the negative reports.  That was the only way Prozac got approved, was by
    covering up the truth and lying to the public about the dangers of this drug.

    Within one decade, there were 39,000 adverse reports about Prozac sent to Medwatch.  It was estimated that the actual number of people who suffered such problems was 100 times as many, or roughly four million people. This makes Prozac
    the most complained about drug in America.

    The FDA received a flood of adverse event reports. but never told the public. It took a decade for the FDA to begin to acknowledge the increased suicides and the violence it can trigger in some people.

    It has been demonstrated that suicide related to Prozac is two to three times higher than any other anti-depressant.

    Prozac's maker, Eli Lilly not only knew their star drugs were more dangerous than alternatives, but they actively sought to suppress the release of that information in order to protect profits.  They have frantically fought any change in the prescribing guidelines for antidepressants even after allegations linking the drug to suicides, murders, murder-suicides and mass murder-suicides because of financial greed.

    When Prozac came to market, Eli Lilly's value on Wall Street, its capitalization, was around 2 billion dollars. By the year 2000, the time when Prozac was its number-one drug, its capitalization reached 80 billion dollars -- a forty-fold increase.

    The con of pharmaceutical-based medicine is the biggest con ever perpetrated on the American people.  Virtually the entire profession has been bought out and participates in this scheme.  On average, every physician in the country gets $13,000 per year from the drug companies. Some get about $500,000 a year, and it has been so successful that no one within academic medicine can speak out.  Everyone gets rich -- the drug companies, the psychiatrists, the researchers, the advertising agencies -- It's all a big gravy train.  And the clients get drugged out of their minds and damaged for life.

    Now that Eli Lilly has lost patent protection on Prozac, they need a new revenue stream.  People pamper their pets now more than ever and Eli Lilly is going to take full advantage of it.

    As a side-note, if your dog has anxiety or depression, there are plenty of natural herbal remedies that work better than pharmaceutical drugs and have no side effects at all.  They work just as well for people too.

      My dog is super aggressive and has attacked our other animals a number of times. We were at out wits end the last time (she really hurt our other dog rather badly) and nothing seems to help. Making it worse is the fact that most of the time she is very loving. You can never tell what she'll do though. I wanted my vet to pull her canines since they do all the damage but he was against that and prescribed Prozac however it has made her a mess. She is shaking and paranoid all the time. If ANYONE can suggest a naural way to treat her occational aggression I am all ears?! Thanks, Mary

        Mary,
        that is the same problem I am having as well. Now it has become a tough decision. She bites and is aggresive. She is a bull terrier. Was your dog agressive after the prozac? Did you keep your dog on it? We are considering it as well even though I am having a little bit of problems trying to make the right decision. But I guess you will never know till you try.

    ...Are profoundly ignorant, misguided, and prejudiced.

    By and large it's either some variations of "that's terrible", "you dont love your dog", "hugs and classes are the only acceptable therapy" and other similar prejudices.

    All of those are false - the facts are that:

    1- The brain is an organ
    2- Like other organs, it sometimes malfunctions
    3- Treating it is as acceptable as treating, say, a kidney.
    4- Not treating it is as unacceptable as not treating a kidney
    5- Limiting therapy options to only classes and hugs is as foolish as limiting your kidney therapy options to diet changes, classes and petting.

    The simple way to avoid such prejudices is to say to yourself "liver" instead of "brain" when you are reviewing the therapy options available for your dog. 

    It may very well be that, say, a diet change is the best approach to treat your dog, but it may be that medication is the better approach.

    Heart,

    SF51

    PS Regarding separation anxiety, it's a very real issue with some dogs, and it goes well beyond being uneasy or longing for companionship.

    There are physical symptoms, including drooling, elevated heart rates, blood pressure, dilated pupils, shivering and urination.

    The best human analogue for it is a full-fledged panic attack, lasting multiple hours. In addition to producing traumatic suffering, it is also very unhealthy physically.

    Behavior modification can often break the association between separation and anxiety/fear, particularly early on.

    Once the anxiety is entrenched, it becomes far harder to break as the expectation of suffering produces anxiety, which in turn produces  suffering; the cycle is self-reinforcing.

      That is according to the theory that behaviour is caused by the brain...

      Besides, no chemical tests are done on dogs (or people's brains) to determine what chemical is missing so the correct drug can be used.

      That is merely a theory.

      So, who is really ignorant here?

    There are many comments and concerns about "Separation Anxiety" in dogs.   Perhaps this seems obvious or simple, but aren't dogs inherently social animals and run in packs and are pretty much ALWAYS with other dogs and running around if they are in the wild?  If you took any "healthy" dog and let it loose, it would find other dogs to hang out with if it could and would prefer it.   Isn't it actually more unusual that a dog would LIKE to be alone?   Maybe the fact that some dogs can tolerate being alone waiting for their "owner" to come home is really the UNUSUAL thing, or the extraordinary thing?  Not that the animals that can't tolerate it are somehow freaks that should be on drugs.  Drugs may subdue them, but maybe the dog who wants to be with other dogs or humans isn't actually "sick"?

      So what are the natural alternatives then?

      Firstly an understanding of the psychology of the dog-human relationship is needed, and methods of managing this. Here are some good links to start with:-

      Then some of the herbal alternatives to Prozac:-

    I just recently put my dog on Reconcile. My vet prescribed fluoxetine hyrdochloride to my dog not because she has seperation anxiety but because she has general anxiety almost all of the time. Her anxiety did not arise because I don't spend enough time with her or because she was not properly trained. My dog was trained to be a guide dog but was career changed because of her anxiety issues. I exercise my dog very regularly and reward her with positive reinforcement. My household is calm and predictable yet she still has serious anxiety attacks that can last for hours on end.
    I have tried natural remedies and taken her to a behavior specialist. I'm certainly did not put my dog on Prozac for an easy way out, but because I felt like it was our last option. I love my dog and have given her the happiest and healthiest life I can.
