Marquis® Paste is indicated for the treatment of equine protozoal myeloencephalitis (EPM) caused by Sarcocystis neurona. Ponazuril, the active ingredient in Marquis, crosses the blood/brain barrier and reaches the central nervous system where it kills Sarcocystis neurona. This stops the parasite from causing any further damage to the central nervous system. Proven effective with a wide margin of safety. Easy to administer, plus the pre-calibrated oral dosing syringe ensures accurate delivery of each dose.
Active Ingredient: 15% w/w Ponazuril

Store at controlled room temperature between 59°F to 86°F (15°C to 30°C).
Marquis is safe to use in horses, causing few adverse effects.

Side Effects:
Side effects may include skin rash, hives, blisters on nose and mouth, loose stools, mild colic or seizures.

For use in animals only. Not for use in horses intended for food. Not for human use.

Prior to treatment, EPM should be distinguished from other diseases that may cause ataxia in horses. Injuries or lameness may also complicate the evaluation of an animal with EPM. In most instances, ataxia due to EPM is asymmetrical and affects the hind limbs.
Clinicians should recognize that clearance of the parasite by Ponazuril may not completely resolve the clinical signs attributed to the natural progression of the disease. The prognosis for animals treated for EPM may be dependent upon the severity of disease and the duration of the infection prior to treatment.
The safe use of Marquis (Ponazuril) in horses used for breeding purposes, during pregnancy, or in lactating mares, has not been evaluated. The safety of Marquis (Ponazuril) with concomitant therapies in horses has not been evaluated.

Federal law restricts this drug to use by or on the order of a licensed veterinarian.

Disposal of medical sharps:

  1. When you're finished with the syringe and needle, do not try to recap, remove, bend or break the needle. This is where most injuries occur.
  2. Dispose the syringe and needle immediately in a nearby sharps container. All sharps must be deposited in a puncture-proof container. Make sure your storage location is child and animal proof.
  3. As with all product handling, make sure you wash your hands after handling medical sharps.

I give this to my kittens as a coccidia treatment and preventative. 1 dose ELIMINATES coccidia, and even better, once mixed with flavoring, the kittens don't even mind taking it. This is truly the best anti-coccidia drug available!

So glad to see you are offering MARQUIS!! I breed Bullmastiffs, bought a new female breeder that had COCCI but I didn't know it until her entire litter came down with severe diarrhea...I am very fortunate...never had this problem before. Gave 3 doses to my pups and diarrhea GONE. .1 per 10 pounds...sure does beat that other method of twice a day for 2-3 weeks.
