Echinococcus multilocularis
- Nematodes:
Ancylostoma tubaeforme
Toxocara cati
Prevention of heartworm disease (Dirofilaria immitis) if concomitant treatment against
cestodes is indicated.
Minimum recommended dose rate: 2 mg of milbemycin oxime and 5 mg of
praziquantel per kg are given orally as a single dose.
Animals should be weighed to ensure accurate dosing. Depending on the bodyweight
of the cat, the practical dosing is as follows:
Body weight
(kg)
16 mg /40
mg film-
coated
tablets
2-41/2 tablet>4-81 tablet >8-121+1/2 tablet
The veterinary medicinal product should be administered with or after some food.
Doing so ensures optimal protection against heartworm disease.
The product can be inserted into a program for prevention of heartworm disease if at
the same time treatment
of heartworm prevention of one month. For regular prevention of heartworm disease,
the use of a monosubstance is preferred.
Underdosing could result in ineffective use and may favour resistance development.
The need for and frequency of re-treatment(s) should be based on professional advice
and should take into account the local epidemiological situation and the animal’s
lifestyle.
Do not use in cats weighing less than 2 kg.
Do not use in cases of hypersensitivity to the active substances or to any of the
excipients.
Cats:
Very rare
(<1 animal / 10,000 animals
treated, including isolated
reports):
Hypersensitivity reaction
Systemic disorders
(e.g. Lethargy)
Neurological signs
(e.g. Ataxia, Muscle tremor)
Digestive tract disorders
(e.g. Emesis,
Diarrhoea)
: especially in young cats
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 the national competent authority via the
national reporting system. See the package leaflet for respective contact details.
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 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.
It is recommended to treat all the animals living in the same household concomitantly.
When infection with the cestode has been confirmed, concomitant
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.
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 product should take into account local information about susceptibility
of the target parasites, where available.
In the absence of risk of co-infection with nematodes or cestodes, a narrow spectrum
product should be used.

Special precautions for safe use in the target species:
Ensure cats and kittens weighing between 0.5 kg and kg receive the appropriate
tablet strength (4 mg milbemycin oxime / 10 mg praziquantel) and the appropriate dose
(1/2 or 1 tablet) for the corresponding weight band (1/2 tablet for cats weighing 0.5 to
1 kg ; 1 tablet for cats weighing >1 to 2 kg).
No studies have been performed with severely debilitated cats or individuals with
seriously compromised kidney or liver function. The product is not recommended for
such animals or only according to a benefit/risk assessment by the responsible
veterinarian.
The tablets are flavoured. In order to avoid any accidental ingestion, store tablets out
of reach of the 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 product should be stored out of sight and
reach of children. Any unused tablet parts should be returned in the opened blister,
inserted back into the outer packaging and used at the next administration or securely
discarded (see section 5.5).
In the event 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.
Wash hands after use.
Special precautions for the protection of the environment:
Not applicable.
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).
The concurrent use of a tablet containing milbemycin oxime and praziquantel with
selamectin is well tolerated. No interactions were observed when the recommended
dose of the macrocyclic lactone selamectin was administered during treatment with a
tablet containing milbemycin oxime and praziquantel at the recommended dose.
Although not recommended, the concomitant use of a tablet containing milbemycin
oxime and praziquantel with a spot-on containing moxidectin and imidacloprid at
recommended dose rates following a single application was well tolerated in one
laboratory study in 10 kittens.
The safety and efficacy of the concurrent use have not been investigated in field
studies. In the absence of further studies, caution should be taken in the case of
concurrent use of a tablet containing milbemycin oxime and praziquantel with any other
macrocyclic lactone. Also, no such studies have been performed with reproducing
animals.
Any unused tablet parts should be returned to the opened blister, inserted back into
the outer packaging and used at the next administration or securely discarded (see
section 5.5)
Protect from light.
