Rotational oral worming paste for horses.     

What is Revolve?

Revolve is a rotational wormer to complement Evolve, Kelato’s broad-spectrum wormer and boticide. Resistance to deworming chemicals is proven and increasing in Australia. Revolve and Evolve makes rotation easy by providing a sustainable worming solution that minimises resistance and maximises horse and pasture health. 

How does it work? 

Revolve contains two active ingredients, Morantel Tartrate and Oxfendazole. Morantel acts on the nervous system of the parasites causing paralysis. As a consequence, the parasites are unable to attach to the intestinal wall and are expelled from the gut. The form of Morantel in Revolve is particularly soluble, resulting in a high degree of efficacy. Oxfendazole interferes with the metabolic pathways of adults and sterilises eggs within 24 hours of dosing, thereby reducing pasture contamination. 

Revolve is effective against:

  • Larval stages of S. vulgaris
  • Small strongyles
  • Ascarids (roundworms)
  • Pinworms
  • Tapeworms

Features & Benefits

  • Easy grip syringe for smaller hands.
  • Pleasant taste.
  • Rotational wormer to complement Kelato’s Evolve.
  • Made in Australia.


Each gram of paste contains:

175mg Oxfendazole and 245mg Morantel Tartrate.

Directions for use

  • Given orally at the recommended dose rate of 5 mL/100kg bodyweight the 32.5g syringe treats horses of weight up to 550kg.
  • Screw the plastic adjuster out to the weight of the horse, insert the syringe into the side of the horse’s mouth between and the front and back teeth and deposit the paste towards the back of the tongue by depressing the plunger quickly as far as it will go. Immediately raise the horse’s head for a few seconds to ensure the full dose has been accepted.
  • Take care to avoid accidental over-dosage of small or fasting horses.
  • After using discard any unused portion of the syringe within 24 hours.

*NB – This product should not be used in foals or horses weighing less than 100kg.

General Directions

Horses should be subject to an appropriate worm program based on faecal egg counts (FECs). Only worm horses with an FEC of >200 eggs per gram (epg).

  • Autumn and Spring are the key times for worming treatments.
  • Every adult horse should be wormed with a mectin-based wormer (Evolve) in late Autumn.
  • Worm high shedding horses (FEC >200 epg) with Revolve in Spring.
  • Foals should be treated initially at 2 – 3 months of age and receive a minimum of 4 treatments in their first year. Use Revolve in young foals (at least 100kg bodyweight) to target mectin-resistant ascarids. Perform FECs at weaning to determine parasite burden and use appropriate wormer based on results.
  • Pregnant mares should be wormed approximately 4 weeks prior to foaling with Evolve to target intestinal threadworms, which predominantly infect foals.
  • Implement appropriate parasite management strategies – e.g. regular manure removal, paddock rotation, avoid drenching in very hot/cold weather, correctly dose according to weight, feed off ground (e.g. feed buckets), paddock horses according to age, avoid overcrowding and quarantine newcomers.
  • Revolve displays a wide safety margin and may be used in young foals to mature horses. Revolve can be used on mares at any stage of pregnancy and will not adversely affect fertility in breeding stallions.
