Strongyles Are the #1 Cause of Parasitic Colic — Are You Actually Covering Them?
Strongid® Pyrantel Pamoate Paste effectively removes and controls large strongyles, small strongyles, pinworms, and large roundworms — the parasites most responsible for parasitic colic and gut damage in horses.
Safe for foals from eight weeks and pregnant mares, it's the rotational deworming workhorse that vets have trusted for decades.
Every Horse on Pasture Carries a Parasite Burden Right Now
Parasite control is one of those equine health tasks that's easy to deprioritize until a horse colics, loses weight unexpectedly, or has a fecal egg count that comes back alarming at the annual vet check. Large strongyles — the most dangerous — migrate through blood vessels and gut tissue, causing damage that accumulates over time. Small strongyles form larval cysts in the gut wall, particularly dangerous when they emerge en masse in spring.
No deworming program eliminates the risk to zero, but a structured rotational approach using proven active ingredients keeps the burden manageable before damage occurs.
Resistance Is Real — but So Is Under-Treating the Parasites That Matter Most
The equine veterinary community has rightly shifted focus to resistance management — testing before treating, rotating active ingredients, and avoiding over-deworming. But in the effort to avoid overdoing it, some owners under-treat for the most pathogenic species. Large strongyles, once nearly eliminated in managed horse populations, are making a comeback on properties where deworming programs have gone too minimal. Parasitic colic and arterial damage from migrating strongyle larvae are preventable — but only if your program addresses them.
- ✗Large strongyle larvae migrate through arteries, causing arteritis and ischemic colic
- ✗Small strongyle hypobiotic larvae emerge in spring, triggering larval cyathostominosis
- ✗Pinworms cause intense rectal itching and tail rubbing, disrupting horse behavior
- ✗Ascarids (roundworms) can cause fatal impaction in foals and young horses
Strongid Covers the Parasites That Cause the Most Damage — Safely and Reliably
Strongid® Pyrantel Pamoate Paste is the pyrantel-class dewormer that effectively removes and controls large strongyles, small strongyles, pinworms, and large roundworms — the core parasites in any comprehensive equine program. The 20ml syringe treats horses up to 1,200 lbs. It's safe for foals from eight weeks, pregnant mares, and debilitated horses — a versatility most dewormers can't match. At $11.99, it's the low-friction cornerstone of a responsible rotational program.
Broad-Spectrum Parasite Control
Targets large and small strongyles, pinworms, and large roundworms — the four primary pathogenic parasites in horses.
Safe for Foals & Mares
Approved for foals from eight weeks of age and safe for use in pregnant and lactating mares.
Ideal for Rotational Programs
Pyrantel pamoate is the standard rotation partner alongside ivermectin and moxidectin for resistance management.
Treats Up to 1,200 lbs
One 20ml syringe covers horses up to 1,200 lbs — accurate, waste-free dosing.
What Riders Are Saying
"
My vet recommended Strongid as the cornerstone of our rotational program specifically for large strongyle control. Easy to dose from the syringe, my horses accept the flavor well, and at this price point I always keep a few on hand. Schneiders has had it in stock consistently when others have run out.
""
I use Strongid every other rotation to cover pyrantel-sensitive parasites. My vet pulled fecal egg counts after the first full season on this protocol and the numbers dropped substantially. Peace of mind for a horse property with turnout groups of eight or more.
""
Safe enough for my pregnant mares and foals right from eight weeks — that's why I've used pyrantel as a regular part of my program for fifteen years. Ordering through Schneiders is easy, ships fast, and the price is fair for what you get.

Why Experienced Horse People Keep Strongid in the Medicine Cabinet
Strongid has been a staple of equine parasite management for decades for simple reasons: it works, it's safe across a wide range of horses including vulnerable populations, and it fills a specific and important role in rotational programs. The pyrantel pamoate mode of action — neuromuscular paralysis of the parasite — is distinct from ivermectin and moxidectin, making it the standard rotation partner for resistance management. At $11.99 it's one of the most cost-effective health decisions you can make per horse, per treatment.
