Oral paste.

A white to light grey homogenous paste.

Horses and other equines.

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.

None.

Care should be taken to avoid the following practices because they increase the risk of development of resistance and could ultimately result in ineffective therapy:

Suspected clinical cases of resistance to anthelmintics should be further investigated using appropriate tests (e.g. Faecal Egg Count Reduction Test). Where the results of the test(s) strongly suggest resistance to a particular anthelmintic, an anthelmintic belonging to another pharmacological class and having a different mode of action should be used.

Resistance to fenbendazole has been reported in cyathostomes in horses. Therefore the use of this product should be based on local (regional, farm) epidemiological information about susceptibility of nematodes and recommendations on how to limit further selection for resistance to anthelmintics.

Assess bodyweight as accurately as possible before calculating the dosage.

Direct contact with the skin should be kept to a minimum. Wear impermeable rubber gloves while administering the product. Wash hands after use.

None known.

Pregnant mares and foals may be safely treated with fenbendazole at therapeutic dosage levels.

None known.

Routine treatment: Administer orally, 1 Syringe per 600 kg bodyweight

(= 7.5 mg fenbendazole/kg bodyweight)

Practical dosage recommendations:

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 600 kg bodyweight daily for 5 days.

(= 7.5 mg fenbendazole/kg bodyweight daily for 5 days)

Single dose treatments:

For the treatment and control of encysted mucosal stages of small strongyles administer 1 syringe per 150 kg bodyweight.

(= 30 mg fenbendazole/kg bodyweight)

For the treatment and control of migrating stages of large strongyles administer 1 syringe per 75 kg bodyweight.

(= 60 mg fenbendazole/kg bodyweight)

For the treatment and control of Strongyloides westeri in sucking foals administer 1 syringe per 90 kg 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 tongue. No dietary control is required before or after treatment.

To ensure administration of a correct dose, body weight should be determined as accurately as possible; accuracy of the dosing device should be checked.

All horses should be routinely wormed with the single dose of Panacur Equine Paste every 6-8 weeks.

Treatment of encysted inhibited and encysted mucosal dwelling larvae should be performed in the autumn (ideally late October/November) and again in the spring (ideally in February). However, for horses who fail to maintain condition or bought-in horses with unknown worming history, the treatment can be given at any time of the year.

Benzimidazoles have a high margin of safety.

Not to be used in horses intended for human consumption.

Treated horses may never be slaughtered for human consumption.

The horse must have been declared as not intended for human consumption under national horse passport legislation.

ATCvet code: QP52AC13.

Fenbendazole is an anthelmintic belonging to the benzimidazole carbamate group

Fenbendazole acts by interfering in the energy metabolism of the nematode. The anthelmintic efficacy is based on inhibition of the polymerisation of tubulin to microtubuli. The anthelmintic affects both adult and immature stages of gastro-intestinal and respiratory nematodes.

Fenbendazole is only partly absorbed from the intestine and reaches maximum plasma concentration 6 (4-8) hours after oral administration.

Fenbendazole is metabolised mainly by enzymes of the cytochrome P -450 system in the liver. The major oxidative metabolite is fenbendazole sulfoxide which is further metabolised to fenbendazole sulfone.

Fenbendazole and its metabolites are distributed throughout the body but highest concentrations are found in the liver.

Fenbendazole and its metabolites are detectable in the plasma only during the first 48 hours following drug administration at a single dose rate of 10 mg fenbendazole/kg bodyweight.

Administration of fenbendazole at a dose rate of 10 mg/kg bodyweight daily for five consecutive days lead to accumulation of fenbendazole during the multiple dosing period whereas the concentrations of its two metabolites show only a slight increase. After the last administration on day 5, all three compounds are eliminated from blood very rapidly, within two or three days.

The elimination of fenbendazole and its metabolites occurs primarily via the faeces.
