Panacur Horse Paste

It treats most roundworms and kills worm eggs and larvae.


Syringes containing 24g of an 18.75% paste formulation of fenbendazole and 0.2% apple and cinnamon flavour as a ready to administer oral anthelmintic for horses. 1g Panacur Equine Paste contains 0.187g active ingredient Fenbendazole PhEur.


A broad spectrum anthelmintic for the treatment and control of adult and immature roundworms of the gastro-intestinal tract in horses and other equines. Panacur also has an ovicidal effect on nematode eggs.

Panacur effectively treats and controls the following roundworm infections:
Large strongyles (adults and migrating larval stages of S. vulgaris; adults and tissue larval stages of S. edentatus).

Benzimidazole susceptible adult and immature small strongyles (Cyathostomes) including encysted mucosal 3rd and 4th stage larvae; it is also effective against encysted inhibited 3rd stage larvae in the mucosa.

Adult and immature Oxyuris spp., Strongyloides spp., and Parascaris equorum.

Dosage and administration

No dietary control is required before or after treatment.

Administer orally, 1 syringe per 600 kg bodyweight (= 7.5 mg fenbendazole/kg bodyweight).

Panacur Equine Granules are also a consideration for horses that will not take a syringe or will spit out paste.

Five day course

For the treatment and control of migrating and tissue larval stages of large strongyles, encysted mucosal 3rd and 4th stage small strongyle larvae and encysted inhibited 3rd stage small strongyle larvae in the mucosa, administer 1 syringe per 600kg bodyweight daily for 5 days (=7.5mg fenbendazole/kg bodyweight daily for 5 days). Panacur 5 Day Guard has been formulated for this purpose in horses and will be a cheaper consideration.

Single dose treatments

For the treatment and control of encysted mucosal stages of small strongyles administer 1 syringe per 150kg bodyweight (=30 mg fenbendazole/kg bodyweight).

For the treatment and control of migrating larval and tissue stages of large strongyles

administer 1 syringe per 75kg bodyweight (=60 mg fenbendazole/kg bodyweight).

For the treatment and control of Strongyloides westeri in suckling foals

administer 1 syringe per 90kg bodyweight (=50 mg fenbendazole/kg bodyweight).

Panacur Equine Paste should be administered orally by squeezing the paste from the syringe onto the back of the horse's tongue.

Key Information

Assess bodyweight as accurately as possible before calculating the dosage. The use of a `weigh-band' is recommended.
Pregnant mares and young foals can be safely treated with Panacur Equine Paste (fenbendazole) at recommended dosage levels.

Recommended dosing programmes

Previous advice was given that all horses should be routinely treated with the single dose of Panacur Equine Paste every 6-8 weeks. It is now recommended a horse worm egg count is undertaken to see if worming is necessary.
Treatment of encysted inhibited and encysted mucosal dwelling larvae should ideally be performed in the autumn (ideally late October/November) and again in the spring (ideally in February). However, for horses that fail to maintain condition or bought-in horses with unknown worming history, the treatment should be given at any time of year.
Contra-indications, warnings, etc
Do not use in horses intended for human consumption.
