Important Clinical Guidance & Warnings
- Veterinary Guidance: Follow specific loading and maintenance dosages prescribed by a veterinarian tailored to your dog.
- Administration: KBroVet may be dosed with or without food. Tablets should not be split.
- Monitoring: Therapeutic concentrations may be reached around 4 weeks. Steady-state serum concentrations generally take 4 to 5 months. Test serum bromide levels at the end of loading, at 4 weeks, at 4 months, and then every 6–12 months.
- Side Effects: Monitor for sedation or gastrointestinal upset and report them to your veterinarian.
KBroVet® is an FDA approved potassium bromide (KBr) medication (marketed as KBroVet-CA1; application number 141-615 — the first potassium bromide chewable conditionally approved by FDA for reasonable expectation of effectiveness) to help control seizures that may occur with IE. KBr does not stop seizures altogether but increases the threshold for seizures and stabilizes neurons against the excitatory signals that start a seizure, which can result in more stable seizures and a more normal life—at least to the extent of having more predictable seizures.
The first step to getting the KBroVet dosage for dogs correct is to know what form you are using, as there are differences in dosage and administration. Since KBr does not undergo hepatic metabolism like many other antiepileptics, it may be a safer/softer alternative in dogs with impaired liver function, and the French vanilla flavored chewable tablets are easier to work into a pet’s daily schedule, lessening the chances of a missed dose.

K•BROVet® Oral Solution is a butterscotch vanilla flavored liquid containing 250 mg of potassium bromide per mL, with cyanocobalamin and pyridoxine HCl. As a chemical, potassium bromide is a crystalline, bitter-tasting and odourless substance with a high water, glycerol and ethanol solubility and a molar mass of 119.002 g/mol.
Below, let’s take a look at how KBroVet dosage for dogs by weight is calculated, from loading doses to long-term maintenance.
What is KBroVet Dosage For Dogs?
Dogs typically require a daily dose of 25 to 68 mg/kg KBroVet (potassium bromide), depending on the individual canine’s therapeutic requirements and the response to treatment with KBr. Veterinarians will often start treatment with a higher loading dose (120-160mg/kg/day for 5 days) and then switch to a lower maintenance dose (30-40mg/kg/day) due to the time it takes for KBr to reach steady-state serum levels.
KBroVet Oral Solution is standardized at 250 mg/mL and can be dosed precisely by volume. Since the efficacy of the treatment is directly affected by both the amount of chlorides consumed and the blood chloride levels of each dog, always check with your veterinarian regarding the correct safe dose and monitoring program for your dog.

How do you use K-BroVet?
Always feed KBroVet with food as directed by your veterinarian. Don’t offer salty snacks or salty foods when your dog is taking potassium bromide as it may affect the drug.
What is in K-BroVet?
This prescription drug contains potassium bromide, which is known to help prevent seizures by reducing the amount of activity in the cells that can lead to a seizure, by suppressing nerve activity and excitability that can trigger a seizure.
Who makes K-BroVet?
The manufacturer of K-BroVet is called PRN Pharmacal.
What does conditionally approved mean?
Conditional Approval” by the FDA indicates that the product has been shown to be safe, and that it has a reasonable likelihood of effectiveness, but that the sponsor is still gathering evidence of effectiveness for full approval.

What is the difference between KBroVet-CA1 and the previously KBroVet tablets?
The two products have different labelling because of the FDA’s conditional approval for KBroVet-CA1; please refer to the product label and package insert for full details. The new tablets are now non-scored, and no longer contain Cyanocobalamin (Vitamin B-12), but all other ingredients are unchanged.
How big are KBroVet-CA1 tablets and do they have a flavour?
An individual KBroVet-CA1 tablet is the size of a dime, and you’ll find that yes, they have their own special flavor to make them more palatable to dogs.
Key Takeaways
- K-BroVet (potassium bromide chewable tablets) is FDA approved/conditionally approved for the control of seizures as a result of idiopathic epilepsy (IE) in dogs.
- It increases the seizure threshold, which means it helps stabilize neurons against the brain’s overactive signals and helps make seizures less frequent, but not cease altogether.
- Once-daily French vanilla–flavored chewable tablets or butterscotch vanilla-flavored oral solution (250 mg/mL) containing cyanocobalamin and pyridoxine HCl (liver flavored tablets are no longer available).
- Tablets are unscored and may be difficult to divide; are about the size of a dime.
- High half-life of ~21 days, thus a missed dose is not likely to lead to hazardous blood level fluctuations
- It is less toxic to the liver than hepatically metabolised antiepileptics, and is a suitable choice for dogs with liver dysfunction.
- For dogs — not for use in cats, humans, breeding, pregnant/lactating dogs or puppies under 6 months.
- Common side effect is sedation/drowsiness (usually resolves in about 3 weeks); other side effects include increased appetite, increased weight, thirst, urination, vomiting, constipation and ataxia.
- Serious/emergency signs (profound sedation, stupor, ataxia, diarrhea, excess salivation, shivering and skin lesions) should prompt immediate veterinary care.
- Needs to be monitored closely when dietary changes occur, when chloride containing IV fluids are used, when other drugs are used, and in dogs with kidney disease or electrolyte problems
- Interacts with a number of medications (such as phenobarbital, furosemide, tramadol and zonisamide) and dietary salt/chloride intake.
- Should be administered with food and salty food or snacks should be avoided during therapy.
- Store in a container out of reach of children in a controlled room temperature (68-77 F/ 20-25 C), away from heat, moisture and direct sunlight.

Final Thoughts
KBroVet Dosage For Dogs is now a trusted, veterinarian-recommended treatment for idiopathic epilepsy in dogs, providing the same day-to-day seizure control, yet in a convenient once-a-day, dog-friendly formulation. It is not a cure and will not stop seizures altogether, but for many dogs it will provide genuine stability to a condition that can be unpredictable – and for those dogs that are sensitive to liver, it will provide an alternative to hepatically metabolized antiepileptics.
Like any prescription drug, it’s important to work closely with your veterinarian: follow the dosage exactly, be aware of side effects, monitor and be consistent with your vet’s plans, and immediately alert your vet to any unusual symptoms. However, with proper advice and guidance, K-BroVet can play a key role in improving a dog’s epilepsy life.
