Paying less for Fenbendazole

  1. 1

  2. 2

    Fill it at a registered online retailer

    The CMA found online pharmacies 50–60% cheaper than practice dispensing on common medicines — typically £200–£300 a year.

against spp. of tapeworm.
Sheep: For the treatment of sheep infected with benzimidazole susceptible:
Ostertagia spp. spp.

useful but variable efficacy against spp.
Horses
For the treatment and control of adult and immature round worms of the
gastrointestinal tract in horses and other equines.
The product effectively treats and controls the following roundworm infections: Large
strongyles (adults and migrating larval stages of ; adults and tissue
larval stages of ).
Benzimidazole susceptible adult and immature small strongyles (cyathostomes).
The product is also effective for the treatment and control of encysted mucosal 3rd

and 4th stage small strongyle larvae and is also effective against encysted inhibited
3rd stage small strongyle larvae in the mucosa.
Adult and immature spp., spp. and .
Fenbendazole also has an ovicidal effect on nematode eggs.
Shake container before use.
No dietary control is required before or after treatment.
Underdosing could result in ineffective use and may favour resistance development.
To ensure a correct dosage, bodyweight should be determined as accurately as
possible. Accuracy of the dosing device should be thoroughly checked.

feed and give the full dosage as one administration.
Treatment should be repeated when natural re-infection of animals with parasitic
worms occurs.
Horses:
Recommended dosage programme:
Inappropriate use of anthelmintics may increase resistance selection pressure and
lead to reduced efficacy. The decision to use the product should be based on
professional advice and take into account current best practice recommendations
for parasite control.
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 5 ml of
the product per 64 kg bodyweight daily for 5 days (7.5 mg fenbendazole/kg
bodyweight daily for 5 days).
Single dose treatment:
For the treatment and control of encysted mucosal stages of small strongyles
administer 3 ml of the product per 10 kg bodyweight (30 mg fenbendazole/kg
bodyweight).
For the treatment and control of migrating and tissue stages of large strongyles
administer 6 ml of the product per 10 kg bodyweight (60 mg fenbendazole/kg
bodyweight).
For the treatment of diarrhoea caused by in two to three week
old sucking foals administer 5 ml of the product per 10 kg bodyweight (50 mg
fenbendazole/kg bodyweight).
Do not mix with other products.
Do not use in horses and other equines intended for human consumption.
Fenbendazole as a medicated liquid feed should not be used in the treatment of
clinical infestations in cattle and sheep.
Cattle, sheep, horses and other equines:
None known.
Reporting adverse events is important. It allows continuous safety monitoring of a
veterinary medicinal product. Reports should be sent, preferably via a veterinarian, to
either the marketing authorisation holder or its local representative or the national
competent authority via the national reporting system. See the package leaflet for
respective contact details.
When administered by divided dosage in the form of liquid feed, the product may
not be effective against and spp. in cattle and ,
Dictyocaulus and spp. in sheep.
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:
•
class, over an extended period of time.
•
misadministration of the product, or lack of calibration of the
dosing device (if any).
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 benzimidazoles (which include fenbendazole) has been reported in
Teladorsagia, , and species in small
ruminants in a number of countries, including the EU. 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.

Special precautions for safe use in the target species:
When incorporating this product into liquid feed, after thoroughly shaking the
suspension, measure the required volume of the suspension and add it to
approximately 10% of the liquid feed. Thoroughly mix this material and then add the
remaining liquid feed and once again mix to produce a homogenous dispersion.
Mix the medicated feed thoroughly prior to administration for example by rolling the
drum or barrel.
Intensive use or misuse of anthelmintics can give rise to resistance. To reduce this
risk, dosing programmes should be discussed with your veterinary surgeon.

product to animals:
