Overview

Daily dewormer + 2 free Quest Plus a year

  • Equine anthelmintic that provides a continuous, preventive level of pyrantel in the intestinal tract
  • You'll get 1 free syringe of Quest Plus Gel dewormer every 6 months beginning with your 6th shipment
Strongid® C 2X™ (pyrantel tartrate) is an equine anthelmintic designed to be administered on a daily basis to provide a continuous, preventive level of pyrantel in the intestinal tract. Strongid® C 2X™ prevents migration of large strongyle larvae. In addition to your daily dewormer, you will also receive 1 syringe of Quest Plus Gel dewormer every 6 months, beginning with your 6th shipment.

The manufacturer recommends dosing a horse with a larvacidal dewormer such as ivermectin or moxidectin before beginning administration of a daily dewormer, to help destroy existing larvae and adult parasites. They also recommend horses receive ivermectin or moxidectin once or twice per year to control bots and praziquantel once or twice per year to control tapeworms.

    Strongid C2X with Bonus Quest Plus Gel Syringes is rated 4.7 out of 5 by 37.
    Rated 3 out of 5 by from First time trying daily wormer. I have always used paste wormers. Honestly I have never had a problem with the pastes but in reading about SrongidC2X I thought it might be a good thing to try. Just in case the horses try to snack on the manure that has not been picked up in the pasture due to the weather.

    Rated 5 out of 5 by from Amazing Works Great. My pony loves it. Easy to give and I don't have to fight with her every month. Best idea ever!
    Date published: 2012-10-04
    Rated 5 out of 5 by from Smart Paks Easy and affordable. No worries on remembering to order or keeping your horse healthy.

    Rated 5 out of 5 by from Great Product - Will Recommend! I absolutely love this supplement! It makes life so much simpler. And it being in a SmartPak? Just another added bonus!

    Rated 4 out of 5 by from Good product but... I am overall happy with the product, but in my experience with daily wormers you paste worm them before starting the daily wormer. When I called SP to question the paste not being in my shipment I was told that the wormer comes 6 months later? The value rating is low because of the lack of paste wormer.
    Date published: 2011-04-15
    Rated 5 out of 5 by from Worming Made Easy! The Smart Paks of Strongid 2X make worming easy. The Equimax, for rotation, sent separartely when needed makes it even easier. A terrific product and service.
    Date published: 2011-04-05
    Rated 5 out of 5 by from Easy to Use and It Works Strongid C2X and Equimax are the perfect combination. Easy to administer and the Equimax auto shipping reminds me to rotate dewormers. My 16 year old Belgian Draft never had a problem taking these medications.
    Date published: 2011-02-24
    Rated 5 out of 5 by from Love it! The packaging for this feed-thru wormer is just too cool. Each horse has his own box, the horses' name is labeled on each dose, and the appropriate dose for each individual is in each daily pak. The only downside to this is that, if you are like me and you have too many horses, opening each pack every morning gets to be a bit much. I love this concept, but I am switching to the Smartpak bulk. I would stick with this if the dosing were such that each horsde only had one segmental piece to open, but my big guys have three segments each. I would think this could be easily remedied by packaging doses in single paks by weight, instead of adding segments for each weight increment.

    Rated 5 out of 5 by from Great Product I love how I am able to have my horses protected from different types of worms on a daily basis. It is also very helpful that the paste is automatically sent to me when I need it, that way I don't have to worry about when I need to use it.
    Date published: 2011-02-11
    Rated 5 out of 5 by from Greatest invention of all time( well....close) In today's fast paced world...busy with family, jobs,traffic etc. It's nice to be able to go to the barn and spend time with my horse rather than spending the time preparing all of his supplements! It is my therapy time!
    Date published: 2010-04-02
    Rated 5 out of 5 by from excellent product All my horses eat strongid c2x readily. I have not had any colics in years. (I have been using this product for several years and am on the Pfizer colic program)
    Date published: 2010-02-13
    Rated 5 out of 5 by from Convenient and Healthy I'm one of the most forgetful people when it comes to medicating my horse, or at least de-worming him(which is strange, considering both of my parents are veterinarians) and he probably, truthfully, only got de-wormed half of the time. Enter, SmartPaks Strongid C2X with Equimax. These nifty little plastic containers that came every month, were the ultimate way to get Dexter wormed every month. Now, he gets his de-wormer with his feed everyday, and I can't forget, because there's nothing to forget, since SmartPak sends them out on time every month. This is a great product-it's convenient, and best of all..IT WORKS!

    Rated 5 out of 5 by from Worming Worries Strongid 2x with Equimax makes the worming process a no brainer. The daily Smartpaks and the semi-annual Equimax is all it takes and it's delivered right to my door.
    Date published: 2009-07-16
    Rated 5 out of 5 by from Great product I especially like the fact Sasha gets wormer everyday. They even send a paste wormer twice a year. The SmartPaks are a great convenience!
    Date published: 2009-04-28
    Rated 5 out of 5 by from great purchase very to use, with 7 horses in my barn it's easy to open and get everyone fed.
    Date published: 2009-04-21
    Rated 5 out of 5 by from My horse used strongid at the first barn we were at. We had no problems. We moved to a new barn where they used paste wormers in rotation and my horse had problems with worms until we returned to the strongid.

    Rated 5 out of 5 by from Smart Packs Great product, convienient to use, delivery always on schedule, and most important....our horses are healthy.

    Rated 5 out of 5 by from Horses Love It! Worming has never been easier. No more fighting to worm with the pastes that almost always ends up being spit out. Every evening my horses think they are getting their special treat with dinner - they love it!
    Date published: 2009-04-15
    Rated 4 out of 5 by from My mare was underweight with a dull coat when I bought her. She has been on Strongid C for 6 months and looks fabulous! She has put on atleast 150 lbs and her spring coat is coming in beautifully. Getting the Equimax twice a year makes the whole process convienient. Only improvement would be to ship Equimax at the right time of year to be given.
    Date published: 2009-04-13
    Rated 5 out of 5 by from Smartpaks Smartpaks are so convenient and as a boarder help me know if my gelding is consistently getting his supplemements. Daily Strongid is a nice way to go and my gelding looks great.
