Travel Stugeron disease for dogs?

I have read in various places that this remedy Travel sick person can be given to dogs. how determined the dosage and how long does it last? I have a route five hours with 2 staffs at the weekend.

Many drugs used for animals are also used for humans, but this is not the case all the time, and some human drugs can be toxic for dogs and cats. In addition, drugs that are safe for pets may need to be administered at a different dose from that for humans, because their bodies process drugs differently Stugeron contains cinnarizine, which is part of a group of drugs which has been used for animals. However, it is much newer than other similar drugs for motion sickness and does not been rigorously tested and approved for use in animals. Therefore, there is no dose rate published for the dogs to the vet can refer. It is probably safer to avoid this medicine for now. There are other older drugs used for fight against the sickness in animals, you can get some from your vet and they will be able to give a recommended dose. If a drug is old and still in use, it is very likely that it is both safe and effective. Another advantage is that they are less expensive than new drugs patented!
