Pyrantel Pamoate (Nemex®, Strongid® T) for Dogs and Cats

Overview of Pyrantel Pamoate (Nemex®, Strongid® T) for Canines and Felines

  •  Pyrantel Pamoate, commonly known as Nemex® or Strongid® T, is used to treat parasites such as roundworms and hookworms in dogs and cats.
  • Most puppies and kittens are born with internal parasites or worms derived from their mother. These parasites may injure the pet and pose health risks to children who might eat soil contaminated with the feces of infected dogs or cats. Accordingly, veterinarians and public health officials advise pet owners to deworm puppies and kittens during the first few months of life.
  • Pyrantel pamoate is one of the most commonly used drugs for de-worming puppies and kittens. It can also be used for parasite control in adult pets and is relatively safe when administered to sick or debilitated animals requiring de-worming.
  • Pyrantel pamoate acts on the nervous system of certain parasites, resulting in paralysis and death of the worm.
  • Pyrantel pamoate is available over the counter but should not be administered unless under the supervision and guidance of a veterinarian.
