What is Strategy T?

  • Broadspectrum wormer effective on all susceptible equine worms including tapeworms.
  • Unique synergistic combination of two active compounds.
  • Superior rotational wormer.
  • Safe to use on all horses including foals, pregnant mares and breeding stallions.
  • Palatable vanilla flavoured paste.
  • Developed and made in Australia.

Why use Strategy T?

1.  Unique combination of actives.

The synergistic combination of oxfendazole and pyrantel in Strategy-T act to complement one another’s activity against all major equine worms including tapeworm and benzimidazole resistant redworms (small strongyles or cyathostomes).

The combination of these two active ingredients in Strategy-T results in a more effective wormer than either active ingredient alone.

2. Ideal rotational wormer.

Strategy-T is the only wormer available that contains the combination of a benzimidazole and tetrahydropyrimadine. This makes Strategy-T the ONLY wormer that effectively treats all major worms of horses including tapeworm and benzimidazole resistant small strongyles that does not contain a macrocyclic lactone (mectin).

This means Strategy-T is the best choice of wormer to use in a rotational program as an alternative to the “mectin” products.

3. Track record of safety.

Extensive internal and independent trials have proven the safety and efficacy of Strategy-T. Safety has been proven in different age groups and life stages of horses including foals, pregnant mares and breeding stallions.

4 Palatable flavour.

Strategy-T is in a palatable vanilla flavoured paste making it easy to administer.

5. Australian developed and made.

Strategy-T is an Australian developed and manufactured product.

When to use Strategy T?

Worming intervals:

How often horses are wormed depends on the property’s management system. It is ideal to use the minimum number of treatments possible in a year, as over worming can lead to resistance.

Depending on a number of factors, some horse owners will need to worm more often than others.

Where there are large numbers of horses kept close together and/or horses are frequently moving on and off a property, there will be a greater need for worm control. This is because these horses will be at the greatest risk of contamination.

Horses in these situations, generally on studs or agistment properties, will need to be wormed every 6 to 8 weeks. It may be possible, where there are low stocking densities, to worm horses less often.

The use of paddock management procedures like manure removal, paddock rotation and grazing with other species will also help lower contamination pressure. All horses should be wormed at least once every 3 months regardless of the conditions in which they are kept.

All horses on a property should be wormed at the same time. New horses should be quarantined and wormed before coming onto the property. If you are unsure about what drenching interval is right for your situation please consult your local vet.


Worms can develop resistance to worming compounds. Once this occurs, the wormer loses its effectiveness and the horse can remain infected with worms even while being treated regularly.

In order to avoid or slow the development and spread of resistance the following rotational strategy is recommended.

The 6 rules of rotation:

1. Do not change wormer every time.

It is recommended to practise rotation of wormers to help prevent or slow the development of resistance. Products should be rotated yearly with one active being used for an entire year and then switching to a different active for the next year.

Strategy-T and Equimax contain completely different actives so make excellent rotation partners. During a Strategy-T year, Equimax needs to be
included twice, as Strategy-T does not treat bots.

Bots must be treated at the end of autumn and the beginning of spring.

2. Change chemical families.

Do not base your rotational choice on box colour. Many wormers available in Australia contain active ingredients of the ‘mectin’ type. If you have been using a ‘mectin’, when you rotate your wormer, it is vitally important to choose a wormer that DOES NOT CONTAIN ANY ‘mectin’ at all.

3. Rotate from ‘...ectins’ to ‘...azoles’ or vice-versa.

When you rotate away from ‘mectins’ you are faced with a bewildering choice of ‘azole’ (also called BZ – benzimidazole) based wormers to choose from. These wormers are easy to identify as they contain active ingredients that end in “…azole”.

After using these wormers for a year you may return to a ‘mectin’ wormer the following year.

4. Not all wormers are 100% effective.

Worms in Australia have a high degree of resistance to ‘azole’– based wormers on most properties. This can create problems on some properties and in some horses.

Strategy-T is one wormer that is a true rotational choice AND is effective against ‘azole’ resistant worms. Strategy-T contains oxfendazole and pyrantel and should form the basis of the ‘non-mectin’ wormer year.

5. Many wormers are not true rotational wormers.

There are some wormers on the market that claim to be rotational wormers. Any wormer containing abamectin, ivermectin or moxidectin is NOT a rotational choice from other ‘mectin’– based drenches.

6. The correct rotational strategy will delay the development of resistance.

If we all adopt the correct strategy in our worming programs we will slow the emergence of resistant worms. It is vitally important that all horses are incorporated into an effective worming program to help prevent diseases such as colic and anaemia.

By adopting a rational rotation program, along with good pasture management such as cleaning your paddocks, the chances of worm-associated disease is significantly reduced.

By following the 6 rules of rotation you can be sure of doing the right thing to protect your horse’s health well into the future.

How to use Strategy T?

Estimating weight.

Most people underestimate a horse’s weight by as much as 20%. Underestimating weight can lead to underdosing. Giving a horse less than the required dose of wormer can leave them at risk of worm-related disease, as potentially worms will be left untreated within the horse.

Underdosing can also encourage the development of resistance in horses by exposing the worms to sub-lethal doses of wormer. It is therefore important to correctly estimate your horse’s weight when deciding on the correct dose of wormer to give them.

It is in fact preferable to give horses a slight overdose rather than an underdose. There are several methods to determine a horse’s weight, the most accurate being a set of scales.

As most horse owners do not have easy access to horse scales, there are several other methods that horse owners can use to get a good estimate of their horses’ weight.

Another method that can be used to estimate weight is by using one of the commercially available weight tapes. Some tapes are accurate and some are not, so it is a good idea to first calibrate the tape using the formula to confirm that it is measuring accurately.

Weight tapes are not suitable to use in immature horses, which have a different body composition to older animals.


Strategy-T is to be given orally at the recommended dose level of 1mL/20kg bodyweight. Insert the syringe into the side of the horse’s mouth in the gap between the front and back teeth.

Advance the plunger as far as it will go, press the plunger to the chosen dosage, depositing the medication on the rear of the tongue. Immediately raise the horse’s head for a few seconds after dosing to ensure the full dose has been swallowed.

Dose at 1ml per 20kg bodyweight. Each weight marking on the plunger will deliver 5mL of paste, which is sufficient to treat 100kg body weight. Each syringe of Strategy-T treats a horse up to 700kg.
