Clinical information

Wormit Plus 12.5mg/125 mg Chewable Tablets for Dogs — SPC Details

Source: VMD Summary of Product Characteristics (SPC). Last updated 27 Mar 2026.

product is only indicated when use against cestodes and nematodes or
prevention of heartworm disease/angiostrongylosis is indicated at the same
time.
Cestodes:
Treatment of tapeworms: Dipylidium caninum, Taenia spp., Echinococcus spp.,
Mesocestoides spp.
Gastrointestinal Nematodes:
Treatment of:
Hookworm: Ancylostoma caninum
Roundworms: Toxocara canis, Toxascaris leonina
Whipworm: Trichuris vulpis
Eyeworm
Treatment of Thelazia callipaeda (see specific treatment schedule under
section 3.9 “Administration routes and dosage”).
Lungworms
Treatment of:
Angiostrongylus vasorum
(L5) and adult parasite stages; see specific treatment and prevention disease
schedules under section 3.9 “Administration routes and dosage”),
Crenosoma vulpis (Reduction of the level of infection).
Heartworm
Prevention of heartworm disease (Dirofilaria immitis) if concomitant treatment
against cestodes is indicated.
Underdosing could result in ineffective use and may favour resistance
development.
To ensure a correct dosage, body weight should be determined as accurately
as possible.
Minimum recommended dose rate: 0.5 mg milbemycin oxime and 5 mg
praziquantel per kg are given as a single dose. The veterinary medicinal
product should be administered with or after some food.
Depending on the bodyweight of the dog, the practical dosing is as follows:
WeightNumber of Tablets5-25 kg1 tablet> 25 - 50 kg2 tablets> 50 - 75 kg3 tablets
In cases when heartworm disease prevention is used and at the same time
treatment against tapeworm is required, the product can replace the
monovalent product for the prevention of heartworm disease.
For treatment of Angiostrongylus vasorum infections, milbemycin oxime should
be given four times at weekly intervals. It is recommended, where concomitant
treatment against cestodes is indicated, to treat once with the product and
continue with the monovalent product containing milbemycin oxime alone, for
the remaining three weekly treatments.
In endemic areas administration of the product every four weeks will prevent
angiostrongylosis by reducing immature adult (L5) and adult parasite burden,
where concomitant treatment against cestodes is indicated.
For the treatment of Thelazia callipaeda
2 treatments, seven days apart. Where concomitant treatment against cestodes
is indicated, the product can replace the monovalent product containing
milbemycin oxime alone.
Do not use in dogs weighing less than 5 kg.
Do not use in case of hypersensitivity to the active substances or to any of
excipients.
See also section 3.5 “Special precautions for use”.
Dogs:
Very rare
(<1 animal / 10,000 animals
treated, including isolated reports):
Digestive tract disorders (such as
Diarrhoea, Drooling, Emesis)
Hypersensitivity reaction
Neurological disorders (such as Ataxia,
Convulsions, Muscle tremors)
Systemic disorders (such as Anorexia,
Lethargy)
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.
The possibility that other animals in the same household can be a source of re-
infection should be considered, and these should be treated as necessary with
an appropriate veterinary medicinal product.
It is recommended to treat all the animals living in the same household
concomitantly.
When infection with the cestode D. caninum
treatment against intermediate hosts, such as fleas and lice, should be
discussed with a veterinarian to prevent re-infection.
Parasite resistance to any particular class of anthelmintic may develop
following frequent, repeated use of an anthelmintic of that class.
Unnecessary use of antiparasitics or use deviating from the instructions given
in the SPC may increase the resistance selection pressure and lead to reduced
efficacy. The decision to use the veterinary medicinal product should be based
on confirmation of the parasitic species and burden, or of the risk of infection
based on its epidemiological features, for each individual animal.
The use of the veterinary medicinal product should follow the implementation of
appropriate diagnostic measures towards mixed infections by nematodes and
cestodes with consideration of animal history and characteristics (e.g. age,
health status), environment (e.g. kennelled dogs, hunting dogs), feeding (e.g.
access to raw meat), geographical location and travel. Judgement of the
administration of the veterinary medicinal product in dogs at risk from mixed re-
infections or in specific at risk situations (such as zoonotic risks), should be
made by the responsible veterinarian.
In the absence of risk of co-infection with nematodes or cestodes, a narrow
spectrum veterinary medicinal product should be used.
Resistance of to praziquantel as well as cases of multi-drug
resistance of Ancylostoma caninum to milbemycin oxime and resistance of
Dirofilaria immitis to macrocyclic lactones have been reported.
It is recommended to further investigate cases of suspected resistance, using
an appropriate diagnostic method. Confirmed resistance should be reported to
the marketing authorisation holder or to the competent authorities.
The use of this veterinary medicinal product should take into account local
information about susceptibility of the target parasites, where available.

Special precautions for safe use in the target species
Studies with milbemycin oxime indicate that the margin of safety in certain dogs
of Collie or related breeds is less than in other breeds. In these dogs, the
recommended dose should be strictly observed.
The tolerance of the veterinary medicinal product in young puppies from these
breeds has not been investigated. Clinical signs in Collies are similar to those
seen in the general dog population when overdosed (see section 3.10
“Symptoms of overdose (and where applicable, emergency procedures and
antidotes)”).
Treatment of dogs with a high number of circulating microfilariae can
sometimes lead to the appearance of hypersensitivity reactions, such as pale
mucous membranes, vomiting, trembling, laboured breathing or excessive
salivation. These reactions are associated with the release of proteins from
dead or dying microfilariae and are not a direct toxic effect of the veterinary
medicinal product. The use in dogs suffering from microfilaremia is thus not
recommended.
In heartworm risk-areas, or in the case it is known that a dog has been
travelling to and from heartworm risk regions, before using the veterinary
medicinal product, a veterinary consultation is advised to exclude the presence
of any concurrent infestation of Dirofilaria immitis. In the case of a positive
diagnosis, adulticidal therapy is indicated before administering the veterinary
medicinal product.
No studies have been performed with severely debilitated dogs or individuals
with seriously compromised kidney or liver function.
The veterinary medicinal product is not recommended for such animals or only
according to a benefit/risk assessment by the responsible veterinarian.
In dogs less than 4 weeks old, tape worm infection is unusual. Treatment of
animals less than 4 weeks old with a combination veterinary medicinal product
may therefore not be necessary.
As the tablets are flavoured, they should be stored in a safe place out of the
reach of animals.
Special precautions to be taken by the person administering the veterinary
medicinal product to animals
This veterinary medicinal product may be harmful when ingested, particularly
for children. To avoid accidental ingestion, the veterinary medicinal product
should be stored out of sight and reach of children.
In case of accidental ingestion of the tablets, particularly by a child, seek
medical advice immediately and show the package leaflet or the label to the
physician.
This veterinary medicinal product may cause hypersensitivity reactions. People
with known hypersensitivity to the active substances or to the excipients,
butylhydroxyanisole (E320) and propyl gallate (E310), should avoid contact with
the veterinary medicinal product. If contact occurs, wash hands and seek
medical advice in case of hypersensitivity reactions.
Wash hands after use.
Special precautions for the protection of the environment
See section 5.5
Other precautions
Echinococcosis represents a hazard for humans. As Echinococcosis is a
notifiable disease to the World Organisation for Animal Health (WOAH), specific
guidelines on the treatment and follow up and on the safeguard of persons
need to be obtained from the relevant competent authority (e.g. experts or
institutes of parasitology).
No interactions were observed when the recommended dose of the macrocyclic
lactone selamectin was administered during treatment with an equivalent
product of comparable composition at the recommended dose.
Although not recommended, the concomitant use of an equivalent product of
comparable composition with a spot on containing moxidectin and imidacloprid
at recommended dose rates following a single application was well tolerated in
one experimental study in beagle dogs at the age 11 months or older. Transient
neurological adverse reactions (poor proprioception, flaccid frontal and hind
legs, incoordination, slight tremors and high stepping gait of the hind limbs only)
were observed after concurrent administration of both products in another study
conducted in puppies aged 8-12 weeks. Such signs were however not
observed in this study after giving the equivalent product of comparable
composition alone.
The safety and efficacy of this combination have not been investigated in field
studies.
In the absence of further studies, caution should be taken in the case of
concurrent use with any other macrocyclic lactone. Also, no such studies have
been performed with breeding animals, Collies, related breeds and their
crosses.
Do not store above 25C.
Not applicable.
