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 My feed store guru lady recommended this product to me when my weanling was hanging on to her winter coat, even though I had used paste dewormer, and I used it since then till about a year ago when I decided to switch to just the paste dewormer to save money. This spring my now seven year old mare was trying to keep some of her winter coat again, so back to daily wormer we went and now she looks great, shiny and sleek.Early on I discovered that the 50 lb bag from Smartpak is the best deal around, and it still is, delivered right to my door. I noticed that other cold-climate reviewers say they skip it during the winter months -- we'll try that as well.

    Rated 5 out of 5 by from GREAT Product Despite being on a regular deworming schedule, it seemed like my mare was having bouts of colic every time I turned around. While I can't attribute Strongid C2X as being THE cure (I introduced digestive/ulcer aids into her diet, too), I can tell you that we have not had a single colic episode since starting this product. I am very happy with this item and would readily recommend it to anyone.

    Rated 5 out of 5 by from Strongid C2X Love this Product. This is the best wormer and works great in South FL. Makes me feel better about all the elements we deal with that can lead to those nasty summer/FL sores that are so hard to get rid of!!

    Rated 5 out of 5 by from I have been using strongid for 2 years. I love the fact that it goes into the feed and voila a daily wormer. The pellets mix right in and the horses eat it without problem. I do paste worm along with it. We get tapeworms here.

    Rated 5 out of 5 by from Strongid C2X My horses have been on Strongid for years. I've always purchased from the vet in order to take advantage of the Preventicare colic insurance program, but since the program is no longer available, I decided to add it into my Smartpaks. It is nice to know that my horse is actually getting the correct dose for his weight, rather than the "one size fits all scoop and dump" that usually occurs when buying it in buckets. Added bonus is that it is quite a bit cheaper in Smartpaks than it was from the vet.

    Rated 5 out of 5 by from Continous Daily wormer I have been using Strongid C 2X over a year now, because I have a horse that is very allergic to "no see um's" and my vet suggested worming her every 20 days. That just made her back sore from being too hard on her liver. So I started the feed thru wormer, and it has helped a lot.

    Rated 5 out of 5 by from Nice and easy Seems to work great. I've used this for years and my horse has never had a problem with worms. I also alternate a paste dewormer every 3 months. Easy to use!

    Rated 5 out of 5 by from Safe and Effective Been using Strongid C 2X for approximately 12 yrs now and firmly believe in its benefits. Not only does it kill larvae before they can harm your horse, but also promotes an overall healthier appearance of your horse. Thankful to say none of my horses have ever experienced colic due to parasites and I believe this continuous worming program is the answer!

    Rated 5 out of 5 by from Smart Purchase This product keeps my horses healthy. I use in conjunction with paste worming. This is the best buy through SmartPak - I can buy the 50 lb bag, and have it delivered to my doorstep, for so much less than anywhere else. An economical way to take good care of your horses.

    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.
