It has been observed that vomiting can very occasionally occur after treatment with Drontal Plus. Following facts have been established:
These cases are rare
Vomiting depends on individual sensitivity of the dog:
Trials have been performed in Australia (Hopkins) with a large number of dogs of various sizes, breeds and ages. It statistically appeared that there is no correlation between vomiting and specific dog races, sizes or even the moment of the treatment compared to the moment of the ration intake.
Furthermore, it has to be said that the occasional dog will vomit or react to nearly anything. A few cases have been reported of animals for which later information reveals that they have also reacted to other medicaments like antibiotics or other wormers.
In case of later readministration, it has been noticed that the intensity of side effects (vomiting) often sensibly decreased.
How to react in front of a vet complaining about vomiting in dogs after treatment with Drontal Plus?
Try to know more about the dog, in order to evaluate if other factors are involved:
is it the first time that the dog vomit after administration of a medicament? (individual sensitivity)
was the correct dose administered?
have other dogs been treated at the same time? With reactions? Etc.
In case Drontal Plus treatment reasonably appears to be the cause of vomiting; recognize that this side effect can occur but minimize it. In order to minimize this undesired effect;
mention the arguments from part 1
Rarity
Individual sensitivity
frequent improvement in case of later administration
remention all the admitted advantages of Drontal Plus
High efficacy
Broadest spectrum of activity
Single dose treatment
Easy administration
Compare positively with other competitor products (e.g. Nitroscanate)
No other competitor product brings so many advantages with so little side effects
Try to evaluate the real importance of this problem in order to minimize it. Petowners often dramatize the situation. Therefore, when vets are visited by representatives, they sometimes subjectively exaggerate some side effects;
You must evaluate the real and objective importance of the problem
"Doctor, how many similar cases did you notice this year? How many Drontal Plus boxes (or treatments) did you sell this year?"
Then, if the vet has sold for example 200 boxes while only 4 cases whereobserved, it is easy to let the veterinarian admit that 2% side effect is negligible.
