  • Unique synergistic combination of two active compounds
  • Safe to use on all horses including foals, pregnant mares and breeding stallions
  • Palatable vanilla flavoured paste
  • Developed and made in Australia


  • Unique defence against resistant equine worms. STRATEGY-T contains a unique combination of active ingredients that work synergistically to give STRATEGY-T a superior efficacy
  • STRATEGY-T that has been shown to have comparable activity to mectin wormers (including benzimidazole resistant strains), making it Australia’s best non-mectin based wormer
  • Safe to use on all types of horses including pregnant mares, foals and breeding stallions
  • Each tube can treat horses up to 700 kg


  • 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.

  • Ideal strategic wormer

    STRATEGY-T is the only wormer available that contains the combination of a benzimidazole (BZ) and tetrahydropyrimadine (THP). STRATEGY-T provides a unique option that effectively treats all major worms of horses and that does not contain a macrocyclic lactone (mectin). STRATEGY-T is also registered for the treatment and control of susceptible strains of all common worms in horses, including adult stages of ivermectin, moxidectin and abamectin resistant ascarids. This means STRATEGY-T is the best choice of wormer to use in a sustainable and strategic program for all horses.

  • Can I use STRATEGY-T in breeding horses?

    Yes STRATEGY-T can be used in mares at all stages of pregnancy. Pregnant mares should be treated as normal during their pregnancy taking care not to stress them during treatment. Mares should be wormed two weeks prior to their expected foaling date. Once a mare has foaled, the mare and foal should both be wormed with first foal worming at twelve weeks of age and subsequently every eight weeks so that large burdens are not allowed to develop. STRATEGY-T can be safely used in breeding stallions at any time without adversely affecting their fertility.

  • How often should I worm my horse?

    Autumn and spring will always be key times to worm all horses. Worm all adult horses once in Spring with STRATEGY-T® and once in Autumn with EQUIMAX® or EQUIMAX® ELEVATION. It makes sense to target mectin wormers in the cooler months when bots and small stronglyes are more active inside the horse. Using non-mectin chemicals is typically suited to the warmer months although if summer sores are a problem a mectin product will be needed.

    Worming strategically involves worming your horse based on the parasite lifecycle, risk of disease and likely resistance status of worms. In Australia, seasonal conditions are ideal for parasite growth during most of the year, particularly the warm, wet months of spring and autumn, however, the lifecycle of different parasites mean that they may be more active at different times of the year. When considering a worming program, you must also ensure that you include faecal egg count testing.

  • When should I start worming my foal?

    Once a mare has foaled the mare and foal should both be wormed with the first foal worming recommended at twelve weeks of age. Young horses need to be treated differently to older horses because they are at risk of mectin resistant ascarids. Ascarids appear to be the worm developing resistance to mectins. Generally ascarids are not found in horses over two years of age as horses seem to develop a natural immunity to these worms as they mature. To protect young horses from potential mectin resistance, it is recommended that a combination product registered to treat mectin resistant ascarids, such as EQUIMAX® ELEVATION or STRATEGY-T®, be used. Young horses should be wormed with STRATEGY-T in spring and summer and EQUIMAX ELEVATION in autumn and winter until they are two years old. Faecal egg count (FEC) testing is recommended once they become a yearling to understand their parasite burden and then worm based on results.

  • Why should I use a combination wormer?

    A combination wormer is one that has multiple actives having similar spectra of activity against the same worms. Using a combination wormer increases the efficacy of the product i.e. effectiveness against worms. Also helps to reduce paddock contamination as there are fewer worms on the property and helps with slowing down development of resistance.
