Strongid C 2X Pellets is a daily in-feed equine dewormer from Zoetis containing pyrantel tartrate in a palatable pellet. Fed each day with the grain ration, it provides continuous control of internal parasites in horses — large and small strongyles, pinworms, and ascarids — and aids in the prevention of Strongylus vulgaris larval infestation by killing infective larvae as they are ingested during grazing.
Key facts
- Active ingredient: pyrantel tartrate, fed at a continuous daily dose of 2.65 mg/kg body weight
- Species: horses of all classes
- Available size: pail of pellets (see variant)
- Form: palatable pellets mixed with or top-dressed on the daily grain ration
- Controls: adult large strongyles, adult and 4th-stage larval small strongyles, adult and 4th-stage larval pinworms (Oxyuris equi), and adult and 4th-stage larval ascarids (Parascaris equorum)
- 2X concentration: double-strength formula — you feed half the volume of original Strongid C
How to use
Feed daily according to the body-weight feeding chart on the package, mixed into or top-dressed on the normal grain ration. For best results, all horses sharing a pasture should be on a consistent parasite-control program. Pair daily deworming with regular fecal egg counts and your veterinarian's guidance, and follow your veterinarian's advice on periodic treatment for parasites not covered by pyrantel tartrate.
Safety information
For animal use only; keep out of reach of children and store in a cool, dry place. Pyrantel tartrate has a wide margin of safety in horses. Consult your veterinarian before use in sick or debilitated animals, and for advice on a complete parasite-control program including pasture management.
Frequently asked questions
How is a daily dewormer different from paste dewormers?
Instead of purging parasites every few months, a daily dewormer delivers a low continuous dose that kills strongyle larvae as your horse ingests them while grazing, before they can migrate and cause damage.
Does Strongid C 2X control bots or tapeworms?
No. The daily pyrantel tartrate dose does not control bots, and tapeworm control is not on the label. Your veterinarian may recommend periodic treatment with other dewormers for these parasites.
What does the "2X" mean?
It is a double-concentrated formula of Strongid C, so you feed half as much product per day for the same pyrantel tartrate dose.
Is a prescription required?
No. Strongid C 2X is available without a prescription, though a veterinarian-guided deworming program with fecal egg counts is recommended.
