Overview of Bromides for Canines and Felines A seizure is a convulsion or physical manifestation of abnormal brain electrical activity. A partial seizure involves only a portion of the body whereas a generalized (grand mal) seizure involves the entire body. Many dogs are affected with chronic seizures and treatment is needed to control these events. Bromide belongs to a general class of drugs known as anticonvulsants. Other related drugs in this class include diazepam and phenobarbital. Typically, the chemical bromide is combined with either the potassium or sodium ion to create the drug potassium bromide or sodium bromide. Potassium bromide is commonly abbreviated as KBr. Bromide will depress the excitability of nerves within the brain and results in reducing seizures. Bromide can be used alone or can be combined with another seizure control drug called phenobarbital to control seizures. Bromide is a prescription drug and can only be obtained from a veterinarian or by prescription from a veterinarian. This drug is not approved for use in animals by the Food and Drug Administration but it is prescribed legally by veterinarians as an extra-label drug.
