Potassium Bromide (K-BroVet®)

Potassium Bromide (K-BroVet®) Seizure Medication for Dogs

Potassium bromide (K-BroVet®) is an anticonvulsant medication used to reduce the frequency and severity of seizures in dogs. No seizure medication can guarantee complete seizure freedom, so consistent daily dosing matters for best results.

Potassium bromide is typically given once a day and should always be given with food. Plan refills ahead when possible and set reminders so dosing stays consistent.

Potassium bromide Dosing & Administration

Give potassium bromide once daily with food, following the prescription label and the plan provided for your dog. Set a reminder on a phone or watch to help keep dosing consistent, and schedule refill pickups early when possible.

Missed Doses & Changing Medications

Give potassium bromide on schedule whenever possible. If a single dose is missed, skip the missed dose and give the next dose at the regular scheduled time.

Seizure medications generally require tapering before stopping. Before making any changes to your dog’s seizure medication plan, contact your veterinary team.

Monitoring & Lab Work

Regular veterinary check-ups help track seizure control and medication safety. Biannual visits are commonly recommended to review progress.

Blood work often monitors potassium bromide levels:

  • Check levels three months after starting or changing the dose.

  • Recheck levels twice yearly after that, since drug levels can fluctuate over time.

Special Precautions for Potassium Bromide

Medication form

  • Shake the liquid form well before use.

  • Do not switch between liquid and tablets without discussing it with your veterinarian, since absorption can differ by form.

  • In general, the liquid form is recommended over tablets because it tends to cause fewer gastrointestinal side effects.

Dietary consistency

  • Keep your dog on the same food when possible, since changes in salt content can change how the body metabolizes this medication.

  • Avoid salty snacks and avoid ocean water. Salty snacks or drinking ocean water can dangerously drop medication levels.

IV fluids

  • IV fluids can cause a sudden drop in blood levels of this medication. Discuss potassium bromide with your veterinarian before any surgical procedures or hospitalizations.

Cats

  • Cats shouldn’t receive potassium bromide because it can cause a severe asthma-like respiratory complication.

Potential Side effects of Potassium Bromide

Many dogs take potassium bromide with no side effects or only mild, tolerable side effects. Regular checkups and blood work help support safe use. Contact your veterinary team if any side effect feels excessive or interferes with quality of life.

Reported side effects include:

  • Sleepiness or “drunk” behavior: Some dogs act sleepy or uncoordinated while adjusting, and adjustment can take about two weeks. Keep dogs away from swimming pools and staircases if coordination is poor.

  • Increased appetite: Some dogs become much hungrier. Monitor food intake, and consider discussing diet options with your veterinary team if weight gain becomes a concern. Watch for inappropriate eating, since some dogs start eating toys or getting into the garbage.

  • Increased thirst and urination: Some dogs drink more and urinate more often. Do not restrict water intake during the day. If accidents happen overnight, pull up water after dinner, then offer a full bowl again in the morning.

  • Vomiting: Some dogs vomit on this medication. In some cases, vomiting improves when the daily dose is split in half and given twice a day instead of one full dose once a day. If vomiting occurs, discuss divided dosing with your veterinarian.

  • Pancreatitis: This medication has been associated with pancreatitis in dogs. Dogs with chronic pancreatitis may do better with a different seizure medication.

  • Chloride values on lab work: Chloride levels often read as high on routine blood work. This is expected and happens because the machine can mistake bromide for chloride.
