The tablets can be given directly to the dog or disguised in food. No starvation
is needed before or after treatment.
Tablets should be given as a single administration.
Part tablets should be discarded immediately or returned to the open blister
until used.
If there is a risk for re-infestation, the advice of a veterinarian should be sought
regarding the need for and the frequency of repeat administration.
Do not use in cases of hypersensitivity to the active substances or to any of the
excipients.
Do not use during the 1st and 2nd trimester of pregnancy (see section 3.7)

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.
Fleas serve as intermediate hosts for one common type of tapeworm –
Dipylidium caninum. Tapeworm infestation is certain to reoccur unless control
of intermediate hosts such as fleas, mice, etc. is undertaken.
Parasite resistance to any particular class of anthelmintic may develop
following frequent, repeated use of an anthelmintic of that class.
To minimise the risk of reinfestation and new infestation, excreta should be
collected and properly disposed of for 24 hours following treatment.

Special precautions for safe use in the target species:
Not Applicable.
Special precautions to be taken by the person administering the veterinary
medicinal product to animals:
In case of accidental ingestion, seek medical advice immediately and show the
package leaflet or the label to the physician.
In the interests of good hygiene, persons administering the tablets directly to
the dog, or by adding them to the dog’s food, should wash their hands
afterwards.

Special precautions for the protection of the environment:
Not applicable.
Other precautions:
The veterinary medicinal product is effective against Echinococcus spp. which
does not occur in all EU member states but are becoming more common in
some. 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.
Do not use simultaneously with piperazine compounds as the anthelmintic
effects of pyrantel and piperazine may be antagonised.
Concurrent use with other cholinergic compounds can lead to toxicity.
This veterinary medicinal product does not require any special temperature
