Prazivec Oral Horse Paste, was developed by Riverside Veterinary in New South Wales Australia, in the interests of Equine Health. 

  • Prazivec is a quality drench with the anthlemintics Ivermectin and Praziquantal in a concentrated dose.
  • The drench is thixotropic - when dosed, the ingredients bind with the saliva in the horses mouth and the horse will not spit it out, therefore you know the full dose has been consumed - an important factor to prevent resistance.
  • Is manufactured in Australia to veterinary requirements
  • Is apple flavoured
  • Unique applicator ensures ease of use

Foals should be treated initially at six to eight weeks of age and this treatment repeated regularly as required. Do read up about Faecal Egg Counts, we encourage strategic worming practices.

Ease of use:  

Thanks to the easy trigger applicator, accurate dose measure and apple flavouring, administering the drench is an easy manoeuvre and because of the thixotropic properties in the semi fluid paste, Prazivec bonds with the saliva in the horses mouth. (Horses don't spit it out). Administering the correct dose with no wastage is easy.

A feature of Prazivec is the applicator or drench utensil. The drench is easily administered with one hand using the drench trigger. The horses do not resist the drench due to the apple flavouring. An accurate measure of the appropriate dosage depending on the size of the horse is easily achieved.

"We have been using Prazivec Oral Horse Paste regularly since 2007. Combining drenching with good pasture / anmimal management practices and doing regular faecal egg counts, has enabled us to have a very successful maintenance programme. It has also resulted in using less drench with more efficiency and greater results. Making use of the Prazivec's client benefit of faecal egg counts at a reasonable cost has meant that we can be accurate and drench only those horses when required. This is a great tool for equine health and it saves us money. We have also found the tubes with the excellent trigger applicator makes for an easy time drenching the mares and foals."
