Febendazole/Mebendazole

Although there is a proven resistance to these ingredients now, febendazole- and mebendazole-based wormers can still be used in a rotational schedule. Using a five-day course of this wormer will eliminate small redworm encysted larvae acquired during the grazing season.

Safe-Guard Equine Paste has Febendazole as the active ingredient and controls large and small strongyles, pinworms, ascarids and arthritis caused by fourth stage larvae of S. Vulgaris.

 

 

Moxidectin

Like febendazole and mebendazole, Moxidectin works to remove small redworm larvae, but can do so in a single standard dose. This particular ingredient suppresses egg reappearance, therefore providing a long-lasting dose of redworm control. Moxidectin-based wormers also help to eliminate pinworms, stomach worms, and bots. Moxidectin is not recommended for foals or weak horses.

 Zimecterin Gold has the active ingredients Moxidectin and Praxiquantel and is approved to control more species and stages of equine parasites than any other brand, including benzimidazole-resistant small strongyles.

 

Ivermectin

Ivermectin-based wormers reduce the risk of infestation during winter months and give effective control of both larval and adult stages of major parasites. Additionally, parasites resistant to benzimidazole-based wormers can be removed by Ivermectin instead. If given in a single dose, an Ivermectin-based wormer can control bots.

 AGRI-MECTIN Wormer Paste has the active ingredient Ivermectin and kills 35 stages of worms and bots.

 

Pyrantel

These wormers are great in a rotational schedule because Pyrantel is effective against most adult roundworms. Pyrantel can also be used for the treatment of tapeworms, but should be administered in a double-dose twice a year for this purpose.

Durvet Pyrantel Dewormer Paste has the active ingredient Pyrantel Pamoate and can be administered for the removal and control of mature infections of large strongyles, small strongyles, pinworms, and roundworms in horses and ponies.

 

Praziquantel

Praziquantel products are also effective against tapeworms when administered two different times throughout the year. However, unlike Pyrantel-based wormers’ double dosage, just a single standard dosage of Praziquantel will do the job. When Praziquantel is paired with other active wormer ingredients, it can effectively target more parasites, so care should be taken with the implementation of a rotational worming schedule.

Pfizer Equimax Paste has the active ingredients Praziquantel and Ivermectin and is effective against major parasites as well as 100% effective against tapeworms.
