WARNING!!! Promeris Flea & Tick Not really safe

Hi Everyone,

If  you did not hear this news yet, then please read on and feel free to cross post!

“Got this from a fellow rescuer and thought it might be worth passing along. It’s not one of those got it from a friend of a friend of a friend who knew somebody who might have a dog that this happened to. It’s from a reliable source very close to me. I know her and all of the dogs affected and I’m just glad they’re all safe.” 


This is a very important message to my family & friends who have dogs and cats–and to alert you to the hazard of using a new Flea & Tick Preventative called ProMeris http://www.promeris.com/consumer/ .

This is a new product designed to be a more effective product than other flea/tick treatments that was just released this year. It is available thru a vet and not currently on-line. I got ProMeris this week for my 7 dogs (6 Huskies & 1 Golden-Airedale), and the results were debilitating for nearly all of them including me. Since my incident this week, my vet has pulled it from distribution and alerted the manufacturer, Fort Dodge .

Here are my results:

Within less than 2 hours after applying, 4 of my dogs had vomited from 2-4 times, 3 were disoriented and stumbling, 1
was dragging his back leg, 1 was salivating. I had very similar symptoms like an allergic reaction and my lips were swollen, eyes very red, mucous membranes such as eyes, nose, and mouth were stinging. I was very disoriented and dizzy equilibrium and not able to drive. To make this a short story, all 7 of my dogs were admitted to thhe hospital for
veterinarian care, and 3 of them remained for care, IV fluids and observation for 24 hours. I was in the emergency room.

I’m home now and so are the dogs. We’re all feeling much better. Vet bills were over $2,500 and Fort Dodge is paying for these. Not only can the product cause this reaction, it has a highly noxious odor that permeated the house and
is just starting to dissipate after 3 days.

Your dogs/cats might not have the same reaction, but given my experience;  I wanted to help you all become well-educated about the product.


  1. I just left my 4-yr-old Basenji mix at the all-night emergency clinic with an apparent Promeris toxicity. She presented with lethargy, bradycardia, depression, hypothermia, and ataxia within 12 hours after administration of Promeris. This was her first dose of Promeris – we used Frontline in the past, but our veterinarian preferred Promeris. We’re praying that she’ll recover with no long-term health issues.

    The vet staff called Fort Dodge to report the case and to obtain information on how to treat her. I plan on following up on their call in the morning (left the clinic at 1 AM).

    Please pray for our pooch. She’s a Hurricane Katrina rescue and, as such has had enough trauma in her life. She’s a wonderful dog and we are praying she comes home tomorrow healthy and back to her perky self.

  2. Oh Marsha, this is terrible! Please keep us updated on your dog’s condition. Did your vet call the FDA or the makers of Promeris?

    It is great you never had any adverse reactions to the use of Frontline however, be aware that it too is quite toxic.

  3. My 9 mo old 26 lb. mixed breed is currently in the ER for IV fluids and antedote after a reaction to Promeris. This a.m. she was very lethargic. I checked her vitals and got a heart rate of 48. This was 12 hrs after the dose was applied. She saw her regular vet and he gave her an injection of Antesedan, and she perked up. But three hours later she relapsed with a heart rate of 40 and ended up in ER. I am still awaiting an update. My regular vet said he is seeing many cases of Promeris toxicity and is not going to carry it anymore. I had been a faithful Frontline user for decades, wish I had stayed with it.
