Supaverm should be used strategically against fluke
  • Sheep should be treated in early spring to make sure all adult fluke are eliminated and that the egg shedding is reduced. This should be done before the population of snails increases. Treatment should be repeated 10 to 12 weeks later.
  • The infective challenge of fluke begins to gain momentum in July and reaches it's peak in the autumn.
  • Treatment should take place every 6 - 12 weeks depending on the challenge from mid summer until the end of the year when the challenge from metacercarial should have reduced.
  • It is important to make sure that fluke does not make it onto your farm through new livestock that is introduced to your farm. New livestock must be quarantined and treated with a suitable flukicide.
  • Wet areas should not be used for grazing at times of high risk from fluke.
  • If your livestock persists to show signs of fluke infection after treatment you should seek professional help.

Rotate and protect:

Since there is a limited amount of products available for the treatment of fluke and there is an ever growing resistance to triclabendazole (the active ingredient used in other popular flukicides), it is important to protect ALL flukicide products. It is a necessity that all sheep farmers establish a competent control of fluke for the future.

Triclabendazole resistance is a reality and a strategic rotation program with Flukiver and/or Sperverm can reduce the danger of fluke developing a resistance on your farm.

4.3 Contraindications
Do not administer to animals with known hypersensitivity to the active ingredients.

4.4 Special warnings for each target species
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:
• Too frequent and repeated use of anthelmintics from the same class, over an extended period of time.
• Underdosing which may be due to underestimation of bodyweight, misadministration of the product, or
lack of calibration of the dosing device.
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 tests strongly suggest resistance to a particular anthelmintic, an anthelmintic belonging to another pharmacological class and having a different mode of action should be used.

4.5 Special precautions for use
Special precautions for use in animals:
Supaverm is to be administered carefully with a drenching gun. Care must be taken to avoid causing injury to the
mouth or pharynx during dosing.
Do not exceed the stated dose.

Special precautions to be taken by the person administering the veterinary medicinal product to animals:
Wash splashes from eyes and skin immediately.
Take off immediately any contaminated clothing.
Wash hands and exposed skin before meals and after work.

4.6 Adverse reactions (frequency and seriousness)
At therapeutic doses, Supaverm is not toxic and causes no side-effects.

4.7 Use during pregnancy, lactation or lay
Supaverm can be used at any time during pregnancy and during the lactating period. See section 4.11.

4.8 Interaction with other medicinal products and other forms of interaction
None known.

4.9 Amounts to be administered and administration route
For oral administration.
Bodyweight of animals should be assessed accurately.
If animals are to be treated collectively rather than individually, they should be grouped according to their bodyweight and dosed accordingly, in order to avoid under- or overdosing.
Do not exceed the stated dose of Supaverm.
Shake well before use. 
Invert at least 10 times before use.
The recommended dose is 10 mg/kg BW closantel + 15 mg/kg BW mebendazole.
This corresponds to 1 ml per 5 kg BW.

Supaverm is to be administered by means of a drenching gun.
All sheep on infested pasture should be dosed at regular intervals during the fluke season.
The interval between dosing will depend on the level of pasture contamination; in severe fluke seasons, dosing every 6-8 weeks may be necessary.
Supaverm is active against worm eggs and prevents pasture contamination with fluke eggs for approximately 13
Treatment intervals of 10-12 weeks throughout the fluke season are recommended.
Because of its long half-life, closantel will protect for several weeks against reinfections with the following species in

Residual activity                                   Dose (mg/kg)                       Protection Period
Haemonchus contortus                                            10                                      7 weeks
Oesophagostomum columbianum                            10                                      2 weeks
Gaigeria pachyscelis                                                 10                                      8 weeks
Oestrus ovis                                                              10                                      8 weeks

The veterinary surgeon should give advice regarding appropriate dosing programmes and stock management to achieve adequate parasite control for both fluke- and roundworm infestations.

4.10 Overdose (symptoms, emergency procedures, antidotes), if necessary
Symptoms of acute closantel overdosage are
decreased vision or blindness,
inco-ordination and general weakness.

4.11 Withdrawal Period(s)
Meat and offal: 65 days.
Not authorised for use in ewes producing milk for human consumption including during the dry period.
Do not use within 1 year prior to the first lambing in ewes intended to produce milk for human consumption.

Pharmacotherapeutic group:
Anthelmintics, combinations of benzimidazoles and related substances.

ATCvet Code:

5.1 Pharmacodynamic properties
Supaverm is a combination of the salicylanilide closantel and the benzimidazole mebendazole.
Closantel is highly effective against liver flukes, haematophagous nematodes and larval stages of some arthropods. Mebendazole is highly active against gastro-intestinal nematodes, lungworms and cestodes.

Mode of action:
Closantel is an uncoupler of the mitochondrial oxidative phosphorylation resulting in inhibition of the ATP-synthesis.
This induces a dramatic change in the energy metabolism which finally leads to the death of the parasite.
Mebendazole has a selective anthelmintic action through a specific interaction with the microtubular system of the
absorptive cells, leading to an irreversible lytic destruction and death of the worm.

5.2 Pharmacokinetic properties
Closantel is rapidly absorbed into the systemic circulation after oral administration and peak plasma levels are attained at 24-48 hours after dosing.
In plasma, closantel is bound for more than 99% to albumin.
As a result, tissue distribution is very limited.
On average, tissue levels are 15 times lower than plasma levels.
The elimination half-life from plasma and tissues is 2 to 3 weeks.
Metabolism is absent and the main excretion route is the bile.
The urinary excretion is negligible.

Mebendazole is poorly soluble in aqueous systems, which results in a low dissolution rate and a low absorption.
This is reflected by the high faecal excretion of unchanged parent drug.
The very small fraction absorbed is almost metabolised by first pass metabolism in the liver, which consists of carbamate hydrolysis and ketone reduction.
The degradation products are conjugated to glucuronides and excreted with the bile and urine.
The urinary excretion is relatively poor and consists almost exclusively of metabolites.
The kinetics of the active ingredients are not altered when used in combination.

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 Weigh – do not guess Underestimating the weight of sheep is a common cause of underdosing. Select and weigh the biggest sheep 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.

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.
