What It Is and How It Works

Panacur (Fenbendazole)

Panacur, with the active ingredient fenbendazole, is an antiparasitic medication primarily used in veterinary medicine. It works by disrupting the energy metabolism of parasites, leading to their death. Its action is selective toward parasitic worms, making it a go-to remedy for various intestinal worms such as roundworms, hookworms, and some tapeworms.

Ivermectin

Ivermectin belongs to a class of drugs called avermectins. It binds to specific chloride channels in the nerve and muscle cells of parasites, resulting in paralysis and death of the parasite. Its broad-spectrum activity makes it effective against a variety of internal and external parasites, including certain types of worms, lice, and mites.

Indications / Uses

Panacur (Fenbendazole)

Panacur is primarily indicated for the treatment of a range of gastrointestinal parasites in animals such as dogs, cats, and livestock. Some of the common parasitic infections treated include:

  • Ascarids (roundworms)
  • Hookworms
  • Whipworms
  • Giardia in dogs

In certain cases, fenbendazole is used off-label for treating other infections, under veterinary guidance.

Ivermectin

Ivermectin is used in both veterinary and human medicine. Its indications include:

  • Treatment of onchocerciasis (river blindness) in humans
  • Strongyloidiasis in humans
  • Treatment of head lice and scabies in humans (topical)
  • Heartworm prevention in dogs
  • Control of nematodes and arthropods in livestock

Use in non-approved indications should only be done under clinical supervision due to dosage and safety complexities.

Dosage Forms and Typical Dosing Considerations

Panacur (Fenbendazole)

Panacur is available in formulations such as granules, suspensions, or pastes, used typically in veterinary settings. Dosing depends on the type of animal, weight, and specific parasitic infection.

Ivermectin

Ivermectin is available in tablets for oral use, topical creams or lotions, and injectable forms. The prescribed form depends on the specific condition being treated. Human dosing requires careful consideration of indications and weight, while veterinary dosing varies based on species and parasite type.
