Equitak™ Excel

Equitak Excel contains three active ingredients: Abamectin and Oxfendazole to treat and control gastrointestinal worm parasites: large and small strongyles, large roundworms, (Ascarids, both sensitive and resistant to Abamectin), lungworms, pinworms and stomach bots, and Praziquantel to treat and control all tapeworms.

A9669 Unrestricted

Active Constituents:

Abamectin 4mg/g, oxfendazole 200mg/g and praziquantel 50mg/g in a cream paste for oral administration to horses. Presented in 30g dial-a-dose syringes.

Abamectin stimulates the release of the neurotransmitter GABA in roundworms, increasing membrane permeability of neurons to chloride ions and inhibiting neural transmission, which results in paralysis and death. Praziquantel interferes with the attachment of tapeworms by causing spastic paralysis. It also damages the integument, increasing its permeability to selected cations and destroying the parasites. Oxfendazole destroys roundworms, including abamectin-resistant Parascaris equorum, by inhibiting tubulin synthesis in the parasite, leading to death by starvation.


Treatment and control of all sensitive strains of roundworms, tapeworms and bots in horses.
Treatment and control of the following roundworms: Ascarids  Parascaris equorum (mature and immature) including abamectin-resistant strains; large strongyles Strongylus vulgaris (mature and arterial larval stages), S. edentatus (mature and tissue stages), S. equinus (mature) and Triodontophorus spp. (mature); small strongyles  Cyathostomum sp, Gyalocephalus spp, Cylicostephanus sp. and Cylicocyclus spp. (mature and immature) including benzimidazole resistant strains. Treatment and control of the following hairworms: Trichostrongylus axei (mature); intestinal threadwormsStrongyloides westeri (mature); pinworms  Oxyuris equi (adult and immature); lungworms  Dictyocaulus arnfieldi (mature and immature); and large mouth stomach worms  Habronema sp. Also skin lesions caused by the cutaneous larvae of Habronema and Draschia spp. (summer sores).
Treatment and control of tapeworms  Anoplocephala perfoliata (mature and immature; scoleces and segments) and botsGasterophilus spp. (oral and gastric stages).

Oxfendazole and abamectin may possibly affect development and/or reproduction. Abamectin may have effects on, or via, lactation. Oxfendazole (liver) and abamectin (nervous system) possibly may cause organ damage from repeated exposure at high doses.


For oral use only. 1g/20kg b.w, equivalent to 0.2mg abamectin, 2.5mg praziquantel, 10mg oxfendazole /kg b.w.

 Bodyweight Dose

 600kg 30g

Administration: Set the correct dose rate by turning the plunger lock. Remove cap and insert syringe nozzle into the side of the horse's mouth, through the gap between the front and back teeth. Advance the syringe as far as possible into the mouth, and deposit the paste onto the back of the tongue by pressing the plunger completely to give the measured dose. Then immediately raise the horse's head and hold for a few seconds to ensure the full dose is swallowed.
Further Treatment: Repeat doses should be given every 6–8 weeks in young and in all susceptible horses. When using good control measures to reduce reinfestation, mature horses only require treatment 3–4 times a year.

Safety of Equitak Excel Multidose:
Equitak Excel is safe to use in all classes and types of horses. This includes foals, breeding mares and stallions, pregnant mares (at all stages of their pregnancy) and lactating mares.

Special Precautions:
Product contains abamectin, a member of the macrocyclic lactone family, avermectin/milbemycin family, oxfendazole, a member of the benzimidazole family, and praziquantel, a highly effective cestocidal compound. It is effective against all parasites susceptible to these anthelmintics. However, resistance can develop to any anthelmintic. Correct drenching technique should be used. Ask your local veterinary practitioner or animal health adviser for recommended parasite management practices for your area to reduce development of resistance. It is advisable that resistance tests or checks be conducted regularly when using any parasite treatment.

Methods to Control Horse Parasites in the Environment:
  • Worm regularly;
  • Worm all new introductions and quarantine for at least 24 hours (preferably 48 hours) to empty out before introducing them to pasture and other horses; ·
  • Treat any horse before moving to a new group;
  • Treat all horses grazed together at the same time;
  • Pick up manure regularly – at least once or preferably twice weekly. This is practical in small paddocks and yards;
  • Rotationally graze horse paddocks with sheep, cattle or deer. This helps reduce the pasture worm larvae/egg populations of all equine parasites;
  • Use feed bins and hayracks rather than feeding off the ground;
  • Remove bot eggs regularly from the horse’s hair coat.

How Often Should You Worm Your Horse?:
  • Depends on many factors such as the number of horses grazing together, the number of paddocks in which the horses are grazed, paddock size, and whether or not control measures (mentioned above) are used;
  • For an individualised recommendation of the appropriate worming schedule for your property, consult your veterinarian;
  • Resistance to an anthelmintic or wormer may develop in any of the individual worm species that infest horses. See your veterinarian to check the effectiveness of your wormer, if required.

Withholding Times:
MEAT: Animals producing meat or offal for human consumption must not be sold for slaughter either during treatment or within 63 days of the last treatment.

Human First Aid, Symptoms of Poisoning:

If swallowed, DO NOT induce vomiting. For advice, contact the National Poisons Centre (0800 POISON or 0800 764 766) or a doctor immediately. Handle with care. May be harmful if swallowed. Wash hands and exposed skin before meals and after use. May cause eye irritation. Avoid contact with eyes. Repeated exposure may cause allergic reactions. Avoid skin contact. If skin or hair contact occurs, remove contaminated clothing and flush skin and hair with running water. If splashed in eyes, wash out immediately with water.

Other Information:
Store below 30°C (room temperature), tightly closed, in the original syringe and in the unit box. Store away from light and foodstuffs.
