What Is Toltrazuril?
Toltrazuril is a broad-spectrum antiprotozoal drug used to treat infections caused by coccidia and other protozoa. Unlike many traditional dewormers, Toltrazuril targets intracellular stages of the parasites, interfering with their ability to reproduce and develop.
Why Use Toltrazuril Paste in Horses?
Coccidiosis is not just a problem for dogs or poultry—horses, especially young foals, can suffer from protozoal infections that affect their digestive health, energy levels, and growth. Toltrazuril paste is formulated specifically for oral administration in equines, making it easy to use and highly effective.
Key Benefits of Toltrazuril Paste:
Targets a broad range of protozoal infections
Ideal for foals and immunocompromised horses
Long-acting with a single dose treatment in many cases
Improves recovery time and reduces reinfection risk

Common Equine Conditions Treated with Toltrazuril
1. Coccidiosis
Caused by Eimeria spp., this parasitic infection is often subclinical but can lead to diarrhea, poor appetite, and weight loss.
2. Equine Protozoal Myeloencephalitis (EPM)
Though Toltrazuril is not a first-line treatment for EPM (Sarcocystis neurona), it is being explored in some off-label applications due to its protozoal inhibition properties.
3. General Protozoal Infections
Useful in barns with mixed-species environments or poor sanitation conditions.

Administration Tips:
Use a weight tape to estimate the horse’s weight.
Apply paste onto the back of the tongue for full ingestion.
Ensure the horse does not spit out the dose.
Always consult with your equine veterinarian before starting treatment.
