Curafluke 10% Oral Drench for Cattle
Curafluke 10% Oral Drench is a broad-spectrum flukicide and wormer containing fenbendazole 100 mg/ml and rafoxanide 100 mg/ml, developed for the treatment and control of internal parasites in cattle.
It provides three-way activity against liver fluke, gastrointestinal worms and lungworms. It also treats susceptible tapeworms, helping farmers manage several important parasite groups with one oral drench.
With activity against mature liver fluke and immature fluke over eight weeks old, Curafluke is a practical option for cattle exposed to fluke risk, particularly on wet or poorly drained grazing land.

Understanding Liver Fluke in Cattle
Liver fluke is an important parasite affecting cattle in Ireland, particularly on farms with wet grazing conditions.
Cattle become infected when they ingest infective liver fluke larvae, known as metacercariae, while grazing contaminated pasture.
Wet Ground Increases Fluke Risk
Wet and poorly drained areas can provide suitable conditions for the mud snails involved in the liver fluke lifecycle. These areas may increase the risk of cattle being exposed to infective fluke larvae.
When Is Liver Fluke Most Common?
Fluke risk can increase from late summer through winter, depending on rainfall, temperature and local grazing conditions.
Although some farms have known fluke-prone fields, infection risk should not be ruled out elsewhere. Cattle may encounter contaminated pasture even where liver fluke has not previously been identified as a major problem.
Why Is Fluke Control Important?
- Cattle Health: Liver fluke infection can affect liver function and overall animal condition.
- Growth and Performance: Parasite burdens can reduce feed efficiency and liveweight gain.
- Housing Management: Assessing fluke risk around housing can help farmers plan appropriate treatment.
- Grazing Management: Identifying wet or fluke-prone fields can help reduce exposure.
Curafluke 10% provides treatment against susceptible liver fluke stages over eight weeks old, alongside its activity against gastrointestinal worms and lungworms.
Note: Treatment choice should take account of the age of the fluke infection, farm history and veterinary advice. Curafluke should not be relied upon to treat liver fluke younger than eight weeks.

5 PHARMACOLOGICAL or IMMUNOLOGICAL PROPERTIES
Summary presentation of the active ingredients
Fenbendazole (QP52AC13) is an anthelmintic belonging to the benzimidazole group which acts by blocking fumarate
reductase which results in the inhibition of the formation of adenosine triphosphate (involved in mitochondrial energy).
Rafoxanide (QP52AG05) is a salicylanilide anthelmintic and these are known to be potent uncouplers of oxidative
phosphorylation in animal tissues.
5.1 Pharmacodynamic properties
Fenbendazole, like many benzimidazoles, blocks fumarate reductase which results in the inhibition of the formation of
adenosine triphosphate (involved in mitochondrial energy).
There is also evidence that it inhibits glucose uptake and therefore increases glycogen utilization and depletes the worm’s glycogen reserves.
The overall effect of this action is to effectively starve the parasite to death.
Furthermore this action results in the detachment of the parasites but in the case of intestinal helminths this detachment does not result in loss of contact with the drug whereas in the case of the liver fluke such detachment would reduce such contact.
This probably explains its limited effect on the liver fluke and the good effect on intestinal helminths.
In vitro experiments indicate that salicylanilides, including the commercially used flukicides, oxyclozanide and
rafoxanide, uncouple oxidative phosphorylation in Fasciola hepatica and other parasites.
5.2 Pharmacokinetic properties
Fenbendazole
Fenbendazole is absorbed poorly from the gastro-intestinal tract leading to with low plasma levels of fenbendazole,
oxfendazole and sulphone. It is mainly excreted in the faeces though some of the metabolites that have been identified are excreted in the urine and bile. The active and its metabolites are mainly found in the plasma.
Rafoxanide
Kinetic studies of rafoxanide in cattle have shown that it is absorbed into the blood with a mean peak concentration of
circa 23 μg.ml-1 achieved in 2 to 3 days. Plasma are considerably higher than those in tissues. Only one metabolite
has been identified (3, 5-di-iodosalicylic acid) and this was found in blood tissues and milk. There is little known or
reported on the excretion of rafoxanide though apparently it is excreted in the bile.

Drench correctly
Sheep Oral Drench
The drenching technique is a vital part of ensuring that the wormer does its job effectively. Make sure the sheep are properly restrained and cannot leap around when they are being drenched so they swallow the whole amount. Sheep can also suffer serious injury, or even death, if they are unrestrained and the gun penetrates the tissues at the back of the mouth. Place a hand under the head and tilt slightly to the side. Slot the nozzle in the gap between molar and incisor teeth and then over the back of the tongue. If the wormer is just put into the mouth, it will bypass the rumen as it escapes down the oesophageal groove and will be less effective. This is particularly important for white (BZ) drenches.
Dosing Weight – do not guess. Underestimating the weight of an animal is a common cause of underdosing.
Select and weigh the biggest animal in the group to determine the correct dose.
If there is a wide range of weights, consider splitting the group, then weigh the heaviest in each section.
Do not forget to check that the weigh crate is accurate before starting!
Calibrate and maintain the drench gun
Always check the gun is delivering the right amount before you drench.
Remove the plunger from a 10 ml syringe, put a thumb over the end and squirt the dose into it, making sure there are no air bubbles left.
Adjust the gun until the dose delivered is correct.
Drenching guns should also be well maintained and replaced regularly.
Clean with warm soapy water after use and check springs and tubes to make sure there are no kinks that will form air bubbles.
Withholding food
Research has shown that the efficacy of the white (BZ) and clear (AV) drenches can be improved by withholding food for 12–24 hours before treatment.
It is not advised to deprive heavily pregnant ewes of food, so if you treat this class of stock with anthelmintics, you may wish to use yellow drenches (LV) because their efficacy is less dependent on rumen fill.
Storage
Wormers should be stored securely, away from direct sunlight at 4–25°C.
Check the use-by date and, once open, use within the time shown on the packaging.
Shake white (BZ) products well before use.
Cattle Oral drenches
Oral drenching guns are designed to deliver the treatment towards the back of the mouth over the tongue, so the entire dose is swallowed at once to optimise efficacy.
• Make sure animals are properly restrained, with their head held up • Slide the nozzle of the dosing gun in the side of the mouth and over the tongue so that the entire dose is swallowed immediately
• Drenching equipment must be correctly calibrated and in good working order
• Calibrate the gun using the product just before treatment starts by delivering two or more doses into a graduated measuring cylinder Faulty equipment, or attempting to dose too quickly, may mean that the barrel of the gun does not fill properly or that the liquid is full of bubbles.
