Description

Fenbendazole Liquid Dewormer for Horses – 10% Solution (100 mg/mL)

Parasite control is essential to maintaining your horse’s health, condition, and performance. Fenbendazole 10% Liquid Dewormer contains 100 mg of fenbendazole per mL and is formulated to target and eliminate major internal parasites affecting horses.

Fenbendazole belongs to the benzimidazole class of anthelmintics and works by disrupting parasite energy metabolism, leading to effective elimination of susceptible worms.

This active ingredient is widely used in equine parasite control programs and is found in trusted veterinary brands such as Panacur and Safe-Guard.


What This Product Is Used For

Fenbendazole 10% Liquid is commonly used for the treatment and control of susceptible:

  • Large Strongyles (bloodworms)
  • Small Strongyles (cyathostomes)
  • Encysted Small Strongyles (with 5-day protocol)
  • Ascarids (Roundworms) – common in foals
  • Pinworms
  • Tapeworms (at double-dose protocol)

It plays an important role in strategic rotational deworming programs.


Symptoms of Parasite Infestation in Horses

Horses with internal parasite burdens may show:

  • Weight loss or failure to gain weight
  • Dull or rough hair coat
  • Intermittent colic
  • Diarrhea or loose manure
  • Poor performance or low energy
  • Pot-bellied appearance (especially in foals)
  • Tail rubbing (pinworms)
  • Coughing in young horses (ascarids)

Routine fecal testing and strategic treatment help maintain optimal health.
