Dramamine Dosage for Dogs

By Amanda Delgado

Veterinarians often prescribe an antihistamine called dimenhydrinate, or Dramamine, to reduce motion sickness in dogs. Although the Food and Drug Administration has not approved its use in animals, Dramamine can generally be used safely under the guidance of a veterinarian, according to Dr. Dawn Ruben.

Common side effects include dry mouth, sedation and difficulty urinating. Appetite loss, diarrhea and vomiting can also occur. Taking Dramamine with food might lessen the severity of side effects.

Dramamine can interact with other medications, such as central nervous system depressants. Dramamine should not be given to dogs that are allergic to antihistamines or those with certain medical conditions, such as hyperthyroidism.
