My dog has head tremors after Dramamine. Is this a side effect?

Updated on September 23rd, 2025

Pet's info: Dog | Vizsla | Male | neutered | 1 year and 2 months old | 50 lbs

One year old vizsla has a history of motion sickness. We typically will give him Dramamine in the car and boat and he is fine; minor side effects (drooling, sedation). We gave him 50mg of Dramamine today and he is having head shakes. He has gotten these before but it is lasting longer on this current episode. Was wondering if it has to do with the Dramamine.

Dramamine or dimenhydrinate can cause hyperexcitability in some situations and I'm wondering if the tremors are from this side effect. It's also possible that Marlin has something else going on - if the head shakes last more than about 12 hours I'd recommend seeing your vet for an exam. It might help to video an episode of the tremors in case you need to show your vet. In the future you may want to ask your vet about switching to a different medication for motion sickness.
