Daily dewormer

  • Equine anthelmintic that provides a continuous, preventive level of pyrantel in the intestinal tract

Safe for horses of all ages and reproductive status, including foals over 2 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.

Manufacturers recommend dosing a horse with a larvacidal dewormer such as QUEST before beginning administration of a daily dewormer, to help destroy existing larvae and adult parasites. Manufacturers also recommend horses receive QUEST Plus with praziquantel in late fall to control bots and tapeworms.


Active Drug Ingredient:
Ingredient Per Serving Per Pound
pyrantel tartrate 2.11% 9.6 g
Guaranteed Analysis:
Crude Protein, not less than 11.5%
Crude Fat, not less than 1.5%
Crude Fiber, not more than 22%
Ingredients:: Dehydrated Alfalfa Meal, Wheat Middlngs, Cane Molasses, Mineral Oil, preserved with propionic acid.


Instructions for Use:
Mixing and Feeding Directions: Strongid C2X is to be administered on a continuous basis either as a top-dress or mixed in the horse's daily grain ration at the rate of 1.2 mg pyrantel tartrate per lb of body weight daily. To achieve this dose, administer 0.5 oz of Stongid C2X per 250 lb of body weight. (A Strongid C 2X measuring cup is enclosed. Please note it is differentin size and shape from the original Strongid C measuring cup due to the higer concentration of Strongid C 2X). Strongid C2X should be administered for the entire period that the animal is at risk to internal parasites. Unprotected animals that have grazed may already have an established S. vulgaris larval infestation. Before administering Strongid C 2X, these animals should be treated with a therapeutic dose of a larvacidal product. Foals may be administered Strongid C 2X as soon as consistent intake of grain mix is occuring. This is generally between 2-3 months of age. Sttrongid C 2X may be used in mares at any stage of pregnancy or lactation. Stallion fertility is not affected by the use of Strongid C 2X.

    Rated 5 out of 5 by from Great Product I've been feeding this supplement to my horse now for a couple of years and she does great on it....there is never any trouble with pellets being left in the grain bin! What really stood out about this particular purchase was the ease of purchasing through Smart Pak. The web interface is easy to use, and I love that the horse's name goes directly onto the supplement for easy identification. It shipped very quickly, and Smart Pak had the best prices of anyone around! Thanks Smart Pak!

    Rated 5 out of 5 by from Great deworming alternative I had my horses on Strongid C2X for a few years, and it was so effective, that with current careful paddock management, they have been completely worm free for one year (with bi-annual deworming, but even so, their fecal egg count was zero). It is a bit pricey, but definitely worth it if you want to ensure your nice (expensive) pony is well protected.

    Rated 5 out of 5 by from Great peace of mind I've been using this for a rescue pony who came in full of worms. After a Panacur PowerPac we started the Strongid daily in SmartPaks. He seems much healthier and now we know exactly when he was wormed so he can stay on a schedule!
    Date published: 2010-11-30
    Rated 5 out of 5 by from Easy to use daily wormer We have a horse that is fearful of worming. So using the daily C2X as a SmartPak is great; plus our horses are pasture fed, it's ensures that our horses are getting their worming medicine in daily doses to keep up with their grazing. (The horse is a rescue horse so he's come a long way. :-) ) Our horses think they're getting a daily treat. ;-)
    Date published: 2010-11-23
    Rated 5 out of 5 by from Strongid C2X Wonderful product. Use it on all my horses. Takes the worry out of worming. In my personal experiance, I find my horses are less likely to colic. Their coats are shiny. They are sick less often. This product is especially good for young horses that eat everything in sight, as they are always hungry! That usually means they are packing a load of worms! I always put my babies on Strongid. I also stick to the 3 month paste worming schedule to completely remove all type of parisites.
    Date published: 2010-11-14
    Rated 5 out of 5 by from Works Great I have been using this product on all my horses for years, keeps there coat nice, and keeps the worms away, also keeps them from colic. Great product will use forever.

    Rated 5 out of 5 by from Will Never Take My Horse Off It My horse continues to look the best he ever has on this product. His saddle fits again, he has more muscle than ever, his coat is gleaming and he happily goes to work every day. Wish I would have tried it earlier.
    Date published: 2010-09-10
    Rated 5 out of 5 by from Excellent Insurance I work with and grain my horses daily anyway, so to me it made sense to use a daily dewormer. I have 5 horses and it's super easy to just add a dose to each horses feed. I did a cost comparison between deworming daily and a two way rotation schedule, and with 5 horses on daily dewormer and using Zimecterin Gold twice a year, the cost came out about $160/yr more using the Strongid C2X - to me that's really cheap insurance that your horse will stay parasite free and healthy! And, obviously, a healthy horse looks better, is better able to perform, and is better able to fight off other illnesses. I should note that becasue I'm in Wisconsin, I don't use the dewormer during the coldest winter months, so cost would be higher in the south.

    Rated 5 out of 5 by from has been tested I use Strongid C2X from thaw to first frost and my horses do very well on it. it also seems to help keep coats shiny and the vet has tested my horses while on it for parasites and it always comes up clean

    Rated 5 out of 5 by from Great Product A "must have" for the overall general health and condition of your horse. Start with this product as the foundation/building block for your Smartpaks and move outward with other products according to your horse's individual needs. Very consistant in quality and very palatable.
    Date published: 2010-07-09
    Rated 5 out of 5 by from Easy to use I recently bought a new horse and he had been on the daily worming schedule. I had never wormed by horses daily but I thought I would keep him on his same feeding routine. I find this way of worming very easy and convient and he likes the pellets. I am thinking of switching my other horse to the daily worming instead of the paste wormers.
    Date published: 2010-07-07
    Rated 5 out of 5 by from great for small barns I only have a pony and small horse so it works great for me. I would think it might be a bit pricey for others. Great product.
    Date published: 2010-06-17
    Rated 5 out of 5 by from Will feed it forever This is a must feed! Every horse I've fed it to eats it with no problem and there's no mistakes on the dosage when you get it in the Smartpaks! Worms cause so many problems and Strongid C2X is so easy.

    Rated 5 out of 5 by from Great purchase I'm so glad my horses are getting the proper amount of this instead of me estimating the amount.

    Rated 5 out of 5 by from Been using Strongid for five years We have used Strongid daily wormer for 5 years now and love it! My horses have better coats! We have one mare that had colic off and on, now she seems to be in better shape and not having any colic symptoms! We have pastures and feeding Strongid keeps them free of larvae and safe from spreading worm larvae!

    Rated 5 out of 5 by from Very "smart purchase" I run a training stable for children and horses. Most of the horses belong to me and paste worming for 15 horses is time consuming and messy! Thank you smart pack for simplifying one portion of my busy life.
    Date published: 2010-03-16
    Rated 5 out of 5 by from Best Daily Wormer You can honest tell the difference in the horses that are on the daily wormer from the ones that aren't. It may be a little costly but well worth the peace of mine. The horses love it, never have had one refuse it.
    Date published: 2010-03-15
    Rated 5 out of 5 by from Great Daily Dewormer I have used C2X on my mare for 8 years and it has worked very well. Occasionally she will leave some pellets behind, but not very often. Daily dewormer is one of the best reasons to have smartpak. The doses are always right and never missed!
    Date published: 2010-02-18
    Rated 5 out of 5 by from Excellent Product My T-bred cross was a chronic colicer. It was suggested to start him on a daily wormer after his colic surgery. Not only did it help with his digestive issues, but I believe he is healthier over all !!!

    Rated 5 out of 5 by from Recommend Highly I have ALL my horses on the Strongid C2x. From my weanlings to my senior horses. I spoke with my vet and in the 5 years that I have been using this product I have had no incidences of colic and I own 10 horses.
