Virbac Strategy-T is a broad-spectrum worming paste for horses that combines two active compounds — oxfendazole and pyrantel — in a single treatment. It targets a range of internal parasites including tapeworms, benzimidazole-resistant small strongyles, and mectin-resistant ascarids. Supplied as a 35ml oral paste syringe for weight-based dosing.

The dual-active formula addresses a key challenge in equine worm management: resistance. Oxfendazole covers benzimidazole-susceptible worms, while pyrantel extends coverage to tapeworms and resistant ascarid populations that single-compound products may miss. Together they provide broader protection than either ingredient alone, and the combination suits horses where resistance to either drug class has been identified or is a known concern.

Strategy-T suits situations where a single treatment needs to cover multiple parasite types without reaching for two separate products. The paste formulation is straightforward to administer, and the dual-active approach makes it a practical option in a resistance-aware worming rotation.
