Fen-IverQuantel Paste

Combination active roundworm, bot and tapeworm paste for horses


Active Ingredient

An aniseed-flavoured gel formulation for oral administration. Each 30 mL syringe delivers 120 mg Ivermectin, 1500 mg Praziquantel, and 6000 mg Fenbendazole sufficient to treat a horse of 600 kg bodyweight.


Ivermectin acts as a gamma amino-butyric acid (GABA) agonist that causes neuromuscular blockage, which causes paralysis and death of the parasite. Praziquantel kills cestodes by disrupting the integrity of the tegument and by interfering with glucose metabolism. Fenbendazole interferes with the energy metabolism of the parasite, causing it to starve to death.
