| The one I know about was a very young horse-yearling or even younger. I don't use Quest, but heard that it has instructions not to use on young horses. |

Location: Washington | The cases we heard about were from Quest not being properly used. I've used it for years no problems. Do not use on young horses or ones that are really wormy. That's where the problems came from. Any over wormy horse can colic from impaction, even from simple ivermectin. Same thing went around about Zimectrin Gold a few years back, I think before FB days so wasn't has heard of?
If you are concerned or want to be on the safe side, use the 5 day power pack to start. |

Use Equimax for the tape worms - it works better. And, I have never had a reaction with it. Nor have I read about one. |

I try to rotate my wormers and depending on what types are available (I should order online, but never remember), so once in a while I use it but not much. |

Worlds Greatest Laugh
Location: North Dakota | I have used it for 18 years on various horses....sometimes up to a herd of 10....without any issues. This would include at least 25-30 different horses. Over a decade and I knew about the horror stories other people were telling. I would become scared and use ivermectin or something else. Then the horse would colic and off to the vet we would go and he would scold me for not using quest. When it was the 3rd horse at the vet with colic because I had used a different wormer, I changed and rotate between Quest and Quest Plus. This ended the colic trips to the vet due to worms at least. I have never had a horse react to it...I have had more problems using other wormers due to the fact that the others were not as effective.
I realize that some horses would have an allergic reaction to it but I havent ever had one. I do not use it on weanlings, sick horses and we do not own donkeys.
Here is a Zoetis study recently published in the JAVMA:

| Not disagreeing or agreeing with anyone out there and now I'm aware to keep my eye on a horse after giving quest. This is just my experience, I have always rotated wormers and this includes quest/quest plus and many others and never had a problem. 3 months ago we brought home a poor looking 11.3hh pony that was EXTREMELY wormy. He got quest plus and passed 50/50 poop/worm piles for 3 days and his spirits were fine. I have never had any horse become Sick after quest plus thank goodness. Not saying it won't happen and now I'll e more aware for ponies and babies. (Every pile of poo that pony ha for a month we put in a burn pile and set it on fire LOL) |

I use it too. I still use Quest and Quest Plus. I just prefer Equimax for the tape worms. I alternate between the Quest Plus and Equimax for those once a year, except for on one horse, which Equimax seems to work better. Personal preference for me.
If someone is hesitatant though, go with the Equimax. I just have never heard of a bad reaction from it and it might ease their mind to use it instead of the Quest product. |

Location: Peg-Leg Julia Grimm | I use QuestPlus at least once a year. But I worm at least 2x more during the year. As long as the horse is on an effective de-worming program and is not very young, really sick or underweight there should be no issue. Just get an accurate weight on your horse and don't under or overdose them.
I want to add another thing to the topic. If you use fecals to tell you when and if to worm, you're putting your horse at risk. Not all parasite types shed eggs. Some of the worst don't. So if you blissfully think that you're covered (by clean fecals) and you aren't de-worming at least 2X per year with the heavy duty de-wormsers as well. You aren't touching the types that don't show up in fecals. On that same line of thought the diatomaceous earth that people claim works, is also ineffective against some parasites (if not all IMO) because some are NOT in the digestive track. Besides. Fecals cost as much as a dose of wormer. Why not just de-worm? |

Location: Oklahoma & Texas | Just wormed mine yesterday with quest plus...no complications ...I think there is a time and place for it...fall around the time of first freeze is when bot Flys are being pesky or tapeworms need addressed...my horses test low on fecal but part of reason too is quest stays in their system for up to 84 days so it doesn't just kill them when you first give it ...it helps keep parasite load down for weeks after... anyway I also use equimaxx and ivermec and safeguard and regular quest throughout the year...i don't use quest in babies or pregnant broodmares or nursing ones and wouldnt with heavily infested horses either... it has anti protozoal propertiestoo so some c etc are even recommending It with epm treatments too...to each their own is what i say...there are risks with any medication and some horses are going to be sensitive or allergic just like some people are with medicines too...know your horse and listen to your vet and make informed decisions ! |

Location: Texas | It's not just Quest, technically all ivermectin dewormers should be avoided in foals under 6 months old and in extremely thin animals. The active ingredient in Quest is Moxidectin which is the same class as Ivermectin. The blood brain barrier in young foals and thin animals is not as developed as in adult horses or fatter horses, so ivermectin can cross the blood brain barrier and cause neurologic disease. It's the same reason why collies, shelties, aussies, etc should not be treated with ivermectin unless they have been tested for the MDR1 gene and don't have the mutation, except in dogs it does not go away with age. |

Location: 31 lengths farms | Vet had me use Quest Plus after a power pak too. My mare had a HUGE blood worm issue that had previously been mis-diagnosed as stifle and then SI issues. Turned out her worm load was making her weak in her rearend. She had been on a rotational deworming program and I had owned her since she was a yearling, just a horse that needed more of everything.
Having said that however even now I do a Safeguard wormer, wait a week and then run Quest Plus thru mine when I use it, try to lessen the worm load they might have. The only issue I've ever had with Quest was when my young mare flipped her head and threw a glop of it out, the old JRT licked some up and 45 minutes later she started having seizures before becoming completely paralyzed in about 2 hours. No one at the time knew what to do, poison hotline said call the vet, vet said call poison hotline, manufacturer said call poison hotline. We ended up treating with Amino Acids and activated charcoal, syringed it to her every 30 minutes, by 10 that night she as able to walk with some balance issues and the next day you wouldn't have known anything ever happened so make darn sure you keep the dogs out of it. |

When you give Quest Plus some of the active ingredient is absorbed into the body fat of the animal. It continues to work for up to 84 days after de-worming. This is why you shouldn't use it on a small or young animal. You also shouldn't deworm more than every 90 days with it. The reason for not using it on a young animal is a animal doesn't have the worm load because they are very young and haven't had time and exposure to the types of worms that quest plus is meant to target. Using Q+ on an animal that is thin, sick or has a large worm load it is more dangerous as well. It's also important to accurately determine the correct dosage. Giving too little isn't effective and some of the heartier parasites will survive, leading to resistant parasites. Giving too much is dangerous. There is a smaller safety margin in quest plus than most other wormers.
The reason to power pack a horse is to get encysted strongyles from the intestinal lining. You can accomplish the same thing with Quest Plus and do it better because Quest Plus will continue to kill any new strongyle eggs that are being released. I've never power packed one of my horses. I don't mind if others want to, but it seems like a lot of work, costs the same or more and isn't any more effective than using either quest plus or one of the ivermectin combos. |

I was warned that it could be relatively dangerous and at the first sign of trouble to get her in ASAP. Thankfully she never had any trouble and about 2 weeks after the Quest Plus she absolutely bloomed. |

Ivermectin and moxidectin do not cause worms to build up resistance. This comes from my friend who o has her masters in EQUINE PARASITOLOGY.
Really? Years ago I met a vet at a racetrack to get my horses treated for something else. A man had just jogged his trotter and came in off the track with the mare pooping nothing but worms. They had an entire wheel barrow filled with nothing but worms. The man told the vet he had wormed this filly for several years, faithfully, with Ivermectin every 2 or 3 months. The vet had wormed with something else that produced these results. He told me that it was not the first case he had seen and reported and he had gotten death threats if he did not cease and desist the reporting. Not sure what has happened since in regards to this, will have to ask him.
So I rotate, pick bot fly eggs off whenever I see them and hope for the best. |
