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 Strongid C2X I am very pleased with Stongid C2X. I have had my 2 mares on it for a few months and they are doing very well on it. Research shows that Strongid C2X kills the early stages of EPM larva which is why I started it in the 1st place. One of mares contacted it, she was on EPM medicine for 7 months and she recovered from it with no noticeable lasting effects. I put them on it because I don't want to go through that again, besides the benefits of taking care of the other parasites that plague horses.

    Rated 2 out of 5 by from Somewhat disappointing I love to send good reviews, but can't do it this time. For the price I paid for this product, I discovered the other well known brand is the same strength, ingredient, and costs less both pricewise and due to the fact that a same size bucket lasts much longer.

    Rated 5 out of 5 by from Love this product I feel confident in providing the daily wormer to my horses. My older horse especially does well on this product. His coat is better, his stomach handles this better than paste worming and because we had a problem with pin worms at my barn, my horse is no longer rubbing his tail raw because of the itching of the worms.

    Rated 5 out of 5 by from Love it! I like that this product eliminates the build up of parasites between dewormings (which happens with any rotational deworming program). I don't have to worry about any inflammation of muscles, the GI tract or respiratory tissues that can be associated with larval migrations of various species of intestinal parasites. My vet highly recommends this product as well. Just make sure to dose with Quest or Quest Plus (to get encysted stages, etc.) before starting any Strongid daily dewormer product!My horse eats this product every morning in her grain without issue, and I only need to deworm her with a praziquantel containing product twice a year. So, if your horse is sensitive to paste dewormers (like diarrhea after you give it) or just hates the entire deworming process, this stuff works very well. Also, it's not too pricey when you buy it in bulk.

    Rated 5 out of 5 by from Saved my OTTB I have an OTTB that we pulled from the track and introduced to turnout for the first time in a long time for him. Even with quarterly rotations he was just getting devoured by worms. He was significantly under weight and lethargic no matter what we did. We did a panacur pack and that helped a little but if we went 2 weeks without worming they came back with a vengeance. Finally our vet said Ivermectim every weekend a quest gel every other weekend for 6 weeks and a strongid smartpak maintenance dose. Lifechanging results - he's packed on the weight and has really blossomed. The Strongid is keeping all of the worms at bay between quarterly wormings. He got a 0 count per ounce at his last check. I highly reccommend this for anyone with an OTTB who is having trouble keeping or gaining weight!

My first horse has been with me for 12 years now and this product has kept his digestive system and proper working order. He has never coliced since he has been on it and he has changed feed or hay quality numerous times without being weaned.

    Rated 5 out of 5 by from Help my wormy boy out so much!!! I bought my horse almost a year ago and I have probably had him on Strongid for about 6 or 7 months now. When I got him he was very underweight and had never been wormed in his entire life (he was 7 years old). I never hesitated to eat this and he absolutely loved it! I loved it for him!! He looked great and now his coat is super shiny and he is not wormy looking at all anymore! I would recommend this to anyone that has a horse that has a horse with worm problems!!!

    Rated 5 out of 5 by from Great Product My show horse started colicking for no real reason when he first started getting into hard work. An older vet recommended strongid c2x as he had tried it on another horse with similar problems and the colicking disappeared. There were no worms present in a fecal test, however we tried this product anyway. It appears that the strongid c2x has helped to prevent the colic. I will continue to use this product until my horse reaches the pastures in the sky.

    Rated 5 out of 5 by from One less thing to worry about! After moving to a boarding stable where owners are responsible for deworming, I decided to give a daily dewormer a try. Now I know for sure that my mare is getting the proper dose of dewormer and I don't have to worry about whether it's done or not, on schedule, or in the proper rotation, etc. I use a moxidectin/praziquantel paste dewormer twice a year to control bots and tapeworms, but otherwise, I don't even have to think about it! I do wish the scoop was a little easier to read/use, but it does make it handy if you have a range of horse weights. I prefer the ease of one full scoop, so I was lucky to find another scoop that could be re-used. I don't plan to go back to the rotation deworming regimen, this is cheaper and easier. Some day we'll get on board with the fecal egg counting method, but until then, we'll stick with this.

    Rated 5 out of 5 by from Vet recommended My mare came home with pin worms from the training facility. I always wormed her before when she came home but I forgot this time. I didn't notice the itching at first but by the time I saw it, she had sores. A trip to see my vet for an anti-itch shot, worming and cream. He recommended the Strongid C2X. It's been 6 weeks now and no more itchys and her coat is beautiful.Thank you Smart Paks. Here in the desert it's rural and a long ways to the feed store.
