Merial Zimecterin Gold dewormer paste for horses, 7.35 g — ivermectin + praziquantel, broad-spectrum control

This ready‑to‑use syringe from Merial delivers a precise oral dose formulated for horses and ponies. The combination of ivermectin and praziquantel expands coverage beyond many single‑ingredient products, treating both nematodes (roundworms, strongyles, pinworms, ascarids) and cestodes (tapeworms), plus bots and certain larval stages. The convenient paste format is dosed by weight and is intended for oral administration in horses only; packaging may vary.

Which parasites does this paste control?

Zimecterin Gold targets a wide spectrum of equine parasites, from common adult worms to several larval stages. It is labeled for removal or control of tapeworms, large and small strongyles (including some tissue stages), ascarids, pinworms, bots and others listed on the product label.

• Tapeworms: Anoplocephala perfoliata
• Large strongyles: Strongylus species and early tissue stages
• Small strongyles: adults and fourth‑stage larvae, including some benzimidazole‑resistant species
• Ascarids, pinworms, bots, lungworms and stomach worms

How do I dose and give Zimecterin Gold to my horse?

The paste is supplied in a prefilled syringe and dosed according to body weight so you can deliver the correct amount in one application. Calculate the horse’s weight accurately, select the syringe volume recommended for that weight class, and administer orally—placing the syringe at the side of the mouth and dispensing onto the back of the tongue.

• Contents treat up to approximately 1,250 lb per full syringe (follow label dosing)
• Weigh or weigh‑tape your horse for accurate dosing
• Administer directly into the mouth; avoid external application

Are there safety or use considerations I should know about?

Zimecterin Gold is labeled for oral use in horses only; follow the product label for withdrawal intervals, contraindications and any age or species restrictions. Observe the animal after dosing and consult your veterinarian with any concerns or if your horse has a history of reactions to dewormers.

• For equine oral use only — not for other species
• Read the label for specific safety, age limits and withdrawal times
• Contact your veterinarian before treating pregnant, sick or debilitated animals

How does this product fit into a parasite control program?

Used strategically, a broad‑spectrum paste like Zimecterin Gold can be one component of an integrated parasite management plan that includes pasture hygiene, fecal egg monitoring and rotation of dewormer classes when advised. It is useful when tapeworm control is a management goal alongside treatment for common nematodes and bots.

• Combine with fecal egg counts to guide treatment timing and frequency
• Use pasture management and manure removal to reduce reinfection pressure
• Rotate anthelmintic classes under veterinary guidance to slow resistance

Who is this for: Owners and caretakers of horses and ponies seeking a single‑dose oral product that covers both tapeworms and a wide range of roundworms, bots and larval stages. Ideal for situations where tapeworm control is required in addition to routine nematode treatment, and for handlers who prefer the convenience of a prefilled paste syringe. Always follow label directions and consult a veterinarian for herd‑level parasite planning.
