When administered daily, Strongid® C 2X helps break the cycle of parasite infection in your horse or foal.

Parasitism in horses can lead to a variety of health issues including organ damage, weight loss, poor growth and respiratory problems. In addition, parasite infestations may contribute to colic, which sometimes results in expensive surgery or even death.

Strongid® C 2X is an equine dewormer that provides continuous prevention and control of the following parasites in horses:

  • Large strongyles
  • Small strongyles
  • Pinworms
  • Roundworms

Strongid® C 2X contains pyrantel tartrate, the same active ingredient found in Strongid® C, in an extra concentrated formula to control a variety of equine parasites. It is safe for use in all healthy horses, including pregnant and lactating mares and breeding stallions. Foals may be given Strongid® C 2X as soon as consistent intake of grain mix occurs (usually between 2-3 months of age). Pellets may be used as a top dress or mixed directly into the feed ration.

Supplied as either a 10 lb bucket or a 50 lb bag. One bucket provides 80 days of prevention for a 1000 lb horse, while one bag provides 400 days of prevention.

To control parasites in horses and foals with a convenient paste, we recommend Strongid® Paste.

Should you take a break off of the daily wormer, ever? I do paste worm also to address additional paracites but wonder if I should give the daily wormer a break at any time.

When using Strongid  C2X, do you still have to use paste wormers 4 times a year?

Rated 5 out of 5 by from The horses on my farm receive this product daily, and they have been on it for 11 years. Coupled with a praziquantel (tapeworm) dewormer once a year, my horses' annual fecal egg counts have remained at zero. I recommend this product as part of a consistent worming program administered in consultation with a veterinarian.

Rated 5 out of 5 by from Confident userI have been using Stringed C2x for over a year. My horse looks great and I no longer worry about if it is time to paste worm my horse again. He is still wormed by the vet once a year to cover all the bases. The horse likes the pellets. So no more struggling with the horse to paste worm him. It's a win win.

Rated 5 out of 5 by from Great product to help my rescue ponyI wormed a rescue pony several times but could not seem to get her to gain weight. Finally a fiend suggested this product and to continue the vet proscribed feed program. And finally that skin and bones pony filled out. I think this product knocked out whatever was in her system.

Rated 5 out of 5 by from Great ProductI have two horses on this product since they were babies, they are 20 and 25 now, have never had any problem with colic or anything else. I'm sure this product has helped with keeping those worms from doing any internal damage.

Rated 5 out of 5 by from Trainer Recommended!Our horse trainer recommended Strongid C2X as a year round supplement to quarterly maintenance. Now in addition to the race horse, the entire herd receives Strongid C2X. Couldn't be more pleased with the results!

Rated 5 out of 5 by from No more splat!Our 2 year old was still shedding ascarids after 2 paste treatments. This product has kept her parasite burden low enough for her feces to be “cleaner” and she is growing better
