In rare cases, digestive tract disorders (hypersalivation, vomiting, diarrhoea,
blood in vomit or diarrhoea) have been reported. Do not repeat treatment if
vomiting occurs shortly after dosing. Treat symptomatically.
Neurological disorders (convulsions/epileptic seizures, ataxia, muscle tremors
and collapse) may occur in very rare cases.
The frequency of adverse reactions is defined using the following convention:
- very common (more than 1 in 10 animals treated displaying adverse
reactions)
- common (more than 1 but less than 10 animals in 100 animals treated)
- uncommon (more than 1 but less than 10 animals in 1,000 animals treated)
- rare (more than 1 but less than 10 animals in 10,000 animals treated)
- very rare (less than 1 animal in 10,000 animals treated, including isolated
reports).
Since the most common tapeworm of the dog (Dipylidium caninum) is
transmitted by a flea and has a very short pre-patent period, it is important to
pay attention to flea control to reduce the incidence of tapeworm in the animal.
The advice of a veterinary surgeon, pharmacist or Suitably Qualified Person
(SQP) should be sought regarding the need for and frequency of repeat
treatment.
