Clinical information

Prazendo 50 mg Tablets for Dogs — SPC Details

immature and mature forms of adult tapeworms in dogs. The product is a highly
effective treatment against all the common species of tapeworm infecting dogs in the
United Kingdom including Echinococcus granulosus, Taenia ovis, Taenia pisiformis,
Taenia multiceps, Taenia hydatigena, Taenia taeniaeformis, and Dipylidium
caninum. The veterinary medicinal product is also effective against Echinococcus
multilocularis (see 3.4).
The recommended dosage rate is 5 mg/kg body weight. This corresponds to 1 tablet
per 10 kg body weight.
2.5 – 5 kg½ tablet6 – 10 kg1 tablet11 – 20 kg2 tablets21 – 30 kg3 tabletsOver 30 kgPro rata
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.
The tablets are administered by opening the animal’s mouth and pushing the tablet
over the back of the tongue so that it cannot be rejected.
Alternatively, a tablet can be wrapped in a piece of meat or butter and offered to the
animal or crushed and mixed with the food.
A single dose is all that is required. However, for dogs in rural areas and for packs of
hounds, this dose should be repeated every four weeks to ensure that newly
acquired tapeworms are destroyed before reaching maturity. Dosing must be
associated with strict control of the dog’s diet to ensure that uncooked offal is not
eaten.
For infections with tapeworms, 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 administer to dogs weighing less than 2.5 kg.
Do not administer to unweaned puppies and kittens, as such animals are rarely
infected with tapeworms.
Do not use in cases of hypersensitivity to the active substance or to any of the
excipients.
None known.
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, 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. To avoid reinfection with this parasite, flea control of the animal and its
housing should be carried out at the same time. Unless flea control is complete an
infected flea population may survive, i.e., re-treatment of the animal may be
necessary.
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.
The possibility that other animals in the same household can be a source of re-
infection with fleas and tapeworms should be considered, and these should be
treated as necessary with an appropriate product.
The use of this product should take into account local information about susceptibility
of the target parasites, where available.
As a precautionary measure to prevent the establishment of Echinococcus
multilocularis in the UK, it is recommended that all dogs entering the country be
treated with praziquantel.
