Virbac Ultimum is a broad-spectrum horse wormer and boticide gel containing Moxidectin and Praziquantel — two complementary active ingredients that together provide the most comprehensive worming coverage available in a single equine treatment. Designed for horses and ponies of all sizes.

Moxidectin, a second-generation macrocyclic lactone, provides a long residual effect against large and small strongyles, pinworms, ascarids, hairworms, intestinal threadworms, stomach worms, and bots. Praziquantel adds effective tapeworm coverage — a class of parasite not adequately controlled by macrocyclic lactones alone. The gel format is easy to administer via the horse's mouth. A single treatment delivers broad-spectrum adult and larval worm control including encysted small strongyle larvae.

Virbac Ultimum is the preferred choice for equine owners who want a single-product worming treatment that covers tapeworm alongside the full range of other horse worm species. Its second-generation macrocyclic lactone active ingredient provides one of the longest residual activity periods available.
