Clinical information

Downland Fluke and Worm Oral Suspension — SPC Details

Source: VMD Summary of Product Characteristics (SPC). Last updated 26 Mar 2026.

For the treatment and control of both gastrointestinal and pulmonary
nematode infections, and adult liver fluke infections. The product removes
most mature Fasciola spp (flukes) present in the bile ducts of the liver.
Thoroughly shake the container well before use to ensure that the two active
substances are homogeneously resuspended and therefore the animals
receive the correct dose.

Dosing must be carried out using a suitable gun system, at a rate of 7.5
mg/kg bodyweight levamisole hydrochloride and 15 mg/kg bodyweight
oxyclozanide achieved by administering 2.5 ml per 10 kg bodyweight in
cattle and 0.5 ml per 2 kg bodyweight in sheep.
To ensure administration of a correct dose, body weight should be
determined as accurately as possible; accuracy of the dosing device should
be checked. Animals should be dosed according to their individual weight,
and not dosed as per the heaviest animal in the group, otherwise signs of
overdose may occur (see section 4.10).
Do not mix with other products.
Animals must not be treated within a period of 14 days before or after
treatment with organophosphorus compounds.
At normal oxyclozanide dose levels, cattle may show slight softening of the
faeces with the occasional animal showing increased frequency of defecation
and transient inappetence. Rarely, animals may also display signs of ataxia,
incoordination, recumbency and depression. Photosensitisation associated
with inflammation of the skin (particularly non pigmented skin e.g. muzzle,
udder) has been observed to occur very rarely and which may be painful and
lead to skin sloughing in severe cases.
Additionally, rarely, sheep may show an allergic reaction such as
submandibular oedema, ear flap oedema and swelling of the head. If such a
reaction occurs, appropriate treatment should be administered without delay.
Such reactions may evolve to a more severe condition (anaphylaxis), which
may be life-threatening.
The frequency of adverse reactions is defined using the following convention:
- rare (more than 1 but less than 10 animals in 10,000 animals treated)
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:

•
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 levamisole has been reported in ,
Trichostrongylus
There are reports of resistance in
Resistance to levamisole has been reported in
developed countries such as New Zealand. 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.
To date, no resistance to oxyclosanide has been reported. The use of this
product should be based on local (regional, farm) epidemiological information
about susceptibility of trematodes and recommendations on how to limit further
selection for resistance to anthelmintics.

i Special precautions for use in animals
Care should be taken to estimate accurately the liveweight of animals to be
treated. Animals should not be dosed as per the heaviest animal in the group.
It is important that the container is shaken before use. After treatment, animals
should be moved to clean pasture in order to prevent re-infection. Veterinary
advice should be sought on appropriate dosing programmes and stock
management to achieve adequate parasite control and reduce the likelihood of
anthelmintic resistance developing. Veterinary advice should be sought if the
product does not achieve the desired clinical effect since other diseases,
nutritional disturbances or anthelmintic resistance may be involved.
