Jeffers Ivermectin Paste 1.87% 6ct - Broad-Spectrum Horse Wormer

In this review the Jeffers Ivermectin Paste 1.87% 6ct is evaluated for horse owners who need a straightforward, reliable internal parasite control. The bottom line: this paste delivers broad-spectrum protection in an easy-to-administer format and is best for owners treating multiple horses or maintaining a regular deworming schedule. Our review finds it most valuable for those who prioritize effectiveness against a wide range of worms and bots without complex dosing procedures.

Key Features

• Powerful parasite protection: The paste targets a broad spectrum of internal parasites, including large and small strongyles, pinworms, ascarids, hairworms, large-mouth stomach worms, threadworms, and bots, helping reduce parasite load.
• Paste formulation: The ready-to-use paste makes dosing straightforward so handlers can deliver the correct amount without mixing powders or liquids.
• Broad-spectrum coverage: One product covers many common equine parasites, which simplifies a regular deworming routine for herd management.
• Trusted brand quality: Offered under the Jeffers brand (Dechra), it reflects consistent manufacturing standards commonly expected in veterinary supplies.
• Value pack: The 6-count format provides multiple doses in a single purchase, offering cost-effective parasite prevention for owners with more than one horse or for scheduled treatments.

Who It's For

This ivermectin paste is suited to horse owners, small farms, and equine caretakers who need reliable control of a wide range of internal parasites and prefer a paste they can administer directly. It is a practical option for those treating several animals over time because the 6-count supply stretches across multiple treatments.

It may not be the best choice for situations requiring weight-based individual syringes for very precise microdosing in foals or unusually small equines, or where a veterinary-prescribed alternative is recommended for specific resistance concerns. Owners with questions about resistance or special medical conditions should consult their veterinarian.
