Human Reaction to Hartz Tick and Flea

I have not read through all the posts on this site to know if anyone else has posted of a human having a terrible reaction to Hartz tick and flea. Here is my story.

Last week I helped a friend out by petsitting her little dog. The owner had put Hartz Ultraguard topical tick and flea prevention on her dog before dropping her off. That night I cuddled with the dog and noticed a tickle in my throat and a weak cough. I joked on Facebook that maybe I was allergic to the dog. I should mention I am a huge dog lover and dogs have been in my life forever. My own dogs have used Frontline in the past. I have no allergies at all to dogs or cats or anything.

The next day, my “cold” got worse. I did spend a lot of time with the dog, sleeping in my bed etc. Two days later I could not go to work. I felt sick and achy, was coughing, had a very sore throat and had a fever. I went to a minute clinic to have a strep test. They listened to my chest and said it sounded bad and wanted to call an ambulance. To cut a long story short, I spent the weekend in the hospital. The Hartz product closed my airways and it became very hard to breathe. I was on steroids, drips, had to have lots of respiratory treatments etc. Now, 5 days later, i am home but still weak and coughing. The doctors have little doubt that it was the Hartz product that lead to this severe allergic reaction.

Have there been other cases of HUMANS having adverse effects from a Hartz product. I would be very interested to know. It’s been a terrible week and it will be a very expensive one after 3 days in hospital. ┬áMy friend who applied Hartz feels guilt stricken that her dog put me in the hospital.

  1. This product is dangerous and should never be used on your pets! It is morally reprehensible that pet stores continue to sell it! Hartz is a despicable organization to continue to sell this poison which kills pets and make humans sick. They need to be forced to remove these products off the shelves so that no more animals become sick or die!

  2. yes danielle I HOPE U GET THIS HARTZ HAS KILLED OVER 72,000 ANAMILS IN 1 YEAR MY HUSKY DIED BECAUSE OF HARTZ HE WAS 80 LB i USED 60LB DROPS, KILLED IN TWO DAYS. ABOUT YOUR REACTION i READ ONE GIRL DIED OFF OF THE HARTZ SHAMPOO ,THE CHILD HAD A SEZIERE AND DROWNED IN THE TUB i TELL EVERYONE I COME IN CONTACT WITH ABOUT HARTZ i TRY TO STOP THEM BEFORE THEY GRAB THAT PACKAGE

  3. Im sorry to hear that. But i have to say yes. I didnt mention it earlier about the adverse affect that killed my dog because it was on a different day but truthfully i can swear to you this did happen. After the whole thing with my dog dying from it. We completely forgot to take the shampoo bottle out of bathtub and it leaked all over the tub ofcourse my husband didnt know that so when he got in to take a shower he stepped in the Hartz Flea and Tick Shampoo and noticed that his feet felt like they were burning when his shower was over he noticed that his feet were blistered from where he stepped in the shampoo. I read the front and back of label and there is no health warning pertaining to something like that just a warning stating to wash your hands incase you were eating. I hope this helps.

  4. no… i am very allergic to these poisons as well…. shuts my throat, i get hives, i don’t even touch my dogs for a week after i’ve applied…. i started using the rx pill with my bulldog four years ago and he started having seizures so i went back to topical… after my bulldog died from a seizure in my arms ….
    my new pit is fine with it so far…. but my chihuahua is acting exactly how you see in the other posts…. back end seizes up…. he shakes his leg likes he’s scratching but i know from my other dog… they are partial seizures….. he is uncomfortable and sad looking… im trying to feed him water all day…. i will never use these meds again…. i will just do the yard and use organic and wash them like crazy in the summer…. these meds should be off the shelf and replaced with any of the homeopathic meds…. even if they only work half as well…. i spray their bed with peppermint spray… and do the yard as well…..
    i don’t know… im sorry you guys have this problem as well….. it’s sad….

  5. I put on the hartz ultraguard plus collar for dogs on my dog. I didn’t touch the collar for more than 2 minutes, and washed my hands immediately afterwards, but my skin has been feeling so weird…it doesn’t hurt or anything…it’s just sort of irritated. I don’t feel normal but don’t know if I should be going to the emergency room. I’ve washed my hands numerous times, and I still feel sort of funny. I obviously took the collar off my dog immediately because that scared me, and then I started reading these reviews…my dog doesn’t seem affected but I’m not going to sit around and let her. She seems okay but I’m still kind of worried. What do I do?

  6. I know these posts have to do with Hartz products, but I and my dog are having gross reactions to Adams Flea and Tick Shampoo. I used it today and the stuff was very difficult to rinse off. Hours later, my entire body started itching. I scratched here, and there and when it grew severe enough, I went into the bathroom and looked at the horror I was seeing! My skin started developing hives around my chest, armpits, back, mid left and right sides, hips, legs, feet, and ankles. My dog Shelby (36 lb American Pit Terrier) is salivating like crazy, constantly rolls on his back to scratch, and pants really heavy as though he were short of breath. After reading the poisons used in both Hartz and Adams products, I’m convinced (based on dozens of Class Actions against Hartz) that a poison called Pyrethrin and Pyrethroid which has been responsible for roughly 72,000 pets in a single year, with thousands of negative human reactions. There is a video on youtube where owners of a cat video-recorded their cat having nervous twitching, salivating, and uncontrollable muscle reactions; the poor kitten died. I myself and considering visiting the ER if this doesn’t clear up by morning. Right now I am in torment with all of this severe itching and burning; I feel as though I came under a chemical attack! And it saddens me that the EPA or the FDA continues to sit on this, and they have yet to pull these dangerous products off the shelf. Naturally so as they are likely being paid off to prevent profit-loss for these companies! I say, if they aren’t going to protect us, then they are against us, and must therefore be shut down!

  7. horrible reaction to the hartz flea collar too-whike babysitting my friends dog– she had a new collar put on the day beforei watched her, by that evening i was itching all over horribly-eyes swollen shut. my sister took me to urgent care clinic they have me on strong steroids,benedryl, and a pill to lessen the upset to my somach from all the meds. Worse thing is my friend who is no longer acted very indifferently to me-showing no concern and as a matter of fact said i stress her!! her text to me was all about her and no ask of my condition!! OMG I was shocked and hurt my face is one huge red blotch- stings,painful.
    I don’t blame her or the dog BUT SHIT IS SHE DUMB OR WHAT. MT OTHER FRIENDS SAY A DIMWIT!! CRUDE AND SELF-SERVING USER. I WAS ONLY TRYING TO HELP HER WITH HER NEW DOG—ALL SHE CARED ABOUT WAS HERSELF AND ANY INCONVEIANCE– IN NOT WATCHING HER DOG ONE NIGHT –WHEN STARTING ALL THESE MEDS!! VERY NASTY WOMAN.

  8. I put a hartz collar on our cat late one evening. At 5am, I was up vomiting, had terrible diarrhea, fatigue and headache. After seeking medical help, it was determined a poisoning from the Hartz collar. I’m furious, it could have been our one year old daughter.

    1. I had put Hartz collar on my 2 dogs the next day my partner and was feeling sick, had headache , fatigue, bitter taste in my mouth, chest pain, feeling anxious. We took the flea collar of our dogs. We had to wash all the blankets bc our dogs slept on them and it was expose to the toxic collar. Hartz should be ban!

  9. I bathed my dogs in hartz flea shampoo and have been having terrible allergy attacks whenever the dogs wrestle or run around me since then. They’re so bad my throat gets tight and scratchy and I can’t stop sneezing and crying. Never happened before this.

  10. Wow. I just had a awful allergic reaction from the hartz flea collar. It locked my entire body up for over 48 hrs. It started 3 hrs after I put the dog collar on my mini poodle. I took the dog collar off after 24hrs to see if that was the problem and within a few hrs i felt drastically better. Scarey they can sell this with no warnings especially experiencing the allergic reaction and reading all these comments. Hartz dog flea/tick collars should be banned. It was a Scarey experience I went threw as that flea collar had my body locked up with severe body pain. Single mom with 2 kids and a poodle. I’m thankfully I got the reaction and figured it out as soon as I did and it wasn’t my kids getting that Scarey reaction.

  11. I’m going through this right now, although with a different brand. Same thing last year but didn’t fully isolate the cause. It’s been a nightmare. There were absolutely no warnings on the packaging. It impacted my work. Then my boss said he thought stress was causing my hives and swelling, and demoted me for allegedly not being able to handle my job. I’m furious.

  12. Just put a hartz collar on my dog not to long ago only a couple hours and he started getting very tired not moving and couple more hosue passed by and I feel ridiculously sick have a headache and have been salivating like crazy and feeling dizzy I don’t know if it’s poisoning or not but I didn’t even realize it was hartz till I read this and checked the box

  13. I put a hartz collar on my dog and I ended up with swollen eyes and itching after playing with her…I took it off and threw it away…

  14. I am having a reaction like this after using Adams flea dip on a foster dog who was covered in fleas.. I am not allergic to dogs, have spent my entire life around dogs, yet I am having the most terrible reaction to this foster since treating his fleas. congestion, eyes watery and swollen, asthma kicking in. I considered going to the ER last night because i am truly unable to get a good breath. Has anyone experienced this after using Adams? Does it go away once its worked it way out of the dogs system?

  15. Like everyone else I have a flea issue. Unfortunately as a cab driver one of my customers had transferred a flea infestation to me and infected my 5 cats. I did my best to make sure that I was flea free before entering my home but one had gotten through anyways. So since 2 of my cats are unable to be bathed I decided to take the flea collar route. Within minutes my cats started to show weird and unusual behavior. Also they seemed to be expressing themselves in a manner as to show me that something was seriously wrong. After reading through reviews I had found, ultimately left me in regret and fear. Unfortunately I made the mistake of trusting a company without any thought. I had left the collars on for about 2 days before removing them. At first I thought they were just acting weird because they are not used to wearing collars since they are not need. They are all strictly indoor cats for good reason. Though the symptoms hadn’t dissipated I quickly removed the collars. I tried checking for chemical burns but unfortunately their fur is far too thick to even see. After removing the collars they seemed to returned to normal. I hope this was helpful and I hope those of the Hartz company get what’s coming to them.

  16. I always feel sick a few days after applying a flea treatment to my dog and cat, and it doesnt really make a difference which brand. I have flu-like symptoms – headache, low fever, body aches and extremely worn out. I never get sick in the summer otherwise, so this has to be the only explanation. Ive tried alternative treatments, but unfortunately if you dont catch it in time – the fleas can get bad fast, and no amount of washing and vaccuming can seem to get it in check – especially in the summer when they can survive outside. So out of despiration I turn to the topical treatments. But each and every time I feel sick a day or two later. I use disposable gloves and try to avoid touching my pets a few days after, but I think they rub themselves on things and it ends up all over the house. One thing is to make sure if you have to use it, you read reviews first. Dont use frontline, it was useless – and dont believe that you need to use the product 3xs before you see results…thats just a money grab to make sure you use more of the product before finding out its not working, and then end up using a bunch of other useless products on top of it because the fleas are even worse. I used Advantix for the dog (which if you have cats you may not want to use) which worked quickly. Advantage had worked before for the cat, but their version didnt work for the dog. The point is, if you have to use it, be very careful and use sparingly. Dont use it as a preventative, it is adding extremely harmful chemicals to your household, and unknown long term effects, as well as short term, on your family.
