What is the most important information I should know about K-BroVet:

K-BroVet is a prescription medication FDA approved for veterinary use in dogs. K-BroVet is available as 250 mg and 500 mg double scored, liver flavored tablets as well as a 10 oz (300 ml) butterscotch flavored Oral Solution 250 mg/ ml. The usual initial starting dose for dogs to achieve a serum level of 1 mg/ml is give 54.5 mg/lb once a day for 5 days, then reduce to 13.6 mg/lb once a day. To achieve a serum level of 1.5 mg/ml, give 72.7 mg/lb once a day for 5 days, then reduce to 18 mg/lb once a day. Do not give K-BroVet to any pet other than the pet for whom it was prescribed.

What is K-BroVet:

K-BroVet is an anticonvulsant used in the treatment of seizures in dogs; however, it is not uncommon for veterinarians to use this medication to treat seizures in cats. K-BroVet may be used alone or in combination with other anticonvulsant medications. K-BroVet may also be used for other conditions not listed.

What should I discuss with my veterinarian before giving K-BroVet to my pet:

Tell your veterinarian if your pet is allergic to potassium bromide. Tell your veterinarian if your pet has kidney disease, or if the pet is pregnant or lactating. Inform your veterinarian of any other medications such as diuretics (furosemide, Lasix, Salix), or sedatives your pet may be taking, as well as any vitamins and supplements since interactions may occur. Periodic blood tests are necessary to monitor the level of the drug in the blood.

How should this medication be given:

Give this medication exactly as directed by your veterinarian. K-BroVet may be given with food to reduce some gastric side effects. Leave plenty of water for the pet to drink. If you do not understand the directions ask the pharmacist or veterinarian to explain them to you. Store K-BroVet in a tightly sealed container at room temperature. Keep this medication away from children and pets.

What happens if I miss giving a dose:

Do not miss a dose. Missing a dose may cause a seizure. Give the missed dose as soon as you remember during the same day. However, if you don't remember until the next day, skip the dose you missed and give only the next regularly scheduled dose. Do not give a double dose of the medication.

What happens if I overdose the pet:

Seek emergency veterinary medical treatment. Symptoms of overdose may include extreme sedation, incoordination, loss of appetite, vomiting, constipation, muscle pain or twitching, staggering, inability to use one or more limbs, decreased or slow reflexes, tremors, and other CNS symptoms.

What should I avoid while giving K-BroVet to my pet:

The safe use of this drug in pregnant or lactating animals has not been determined. Use with caution in animals with kidney disease, older animals, and those with other health problems.

What are the possible side effects of K-BroVet:

If your pet experiences an allergic reaction, signs may include facial swelling, hives, scratching, and sudden onset of diarrhea, vomiting, shock, seizures or coma. If these signs occur, contact your veterinarian immediately. Side effects such as transient drowsiness when used with other anticonvulsant medications may last a few weeks. Change in appetite, vomiting, constipation, diarrhea, and incoordination may also occur as well as increased thirst and urination. Dogs may also develop skin rashes or behavior changes. Cats may also develop a respiratory condition similar to asthma. Bromide salts have been associated with the development of pancreatitis. Symptoms may include loss of appetite, abdominal pain, and vomiting. When giving high doses, side effects may include severe vomiting, muscle pain, twitching, staggering, inability to use one or more limbs. If any of these symptoms occur, contact the veterinarian.

What other drugs will affect K-BroVet:

Before giving K-BroVet, tell your veterinarian if your pet is being given a diuretic (Lasix, Salix, furosemide), a sedative, vitamins or supplements.

Where can I get more information:

Your pharmacist has additional information about K-BroVet written for health professionals that you may read.

Customer Reviews
K-BroVet Potassium Bromide is rated 4.777777777777778 out of 5 by 9.
Rated 4 out of 5 by from Controls seizures but hardly "delicious." In terms of controlling seizures, this medication has been great, after the initial loading period. We've only needed to increase the dosage once over the last almost four years (touch wood). No liver toxicity issues so far (my vet said that there's less of a chance of that happening with KBro c/t phenobarbital or some of the other drugs). The one downside - this tablet is hardly a "delicious liver flavour." The only way to get it down is to force it or use pill pockets. I'd love to just give Nellie her meds without having to get the exact ratio of pill pocket over tablet required for her to not be able to smell it, so if this could be improved, you'd go up to 5 stars.

Rated 5 out of 5 by from used for epileptic dog My lab mix started having seizures when she was 2. I put her on phenobarbital when she started to have one seizure per month per my vets advice. She had awful side effects so I took her off the phenobarb. Phenobarb also has long term side effects that can cause organ failure and causes dogs to be dependent (if you don't give them meds they will have seizures). She is 60 lbs and now takes potassium bromide twice a day. She takes a 250 mg in the morning and 500 mg at night. She still has about one seizure every two months but they only last 3 minutes or less and seem to be less severe. This product has less negative side effects and I have been happy with it.

Rated 5 out of 5 by from Knock on Wood!!!!! My 7 year old German Shepherd started having seizures at the age of 2. He was immediately put on phenobarbital because they were so bad (cluster or multiple) in 5 years he had over 1200 seizures. anywhere from 11 to 19 over a 3 day period every 4-6 weeks. I know this cause I mark them all on a calendar. In January he was put on Potassium Bromide and has been taken off the pheno and today Easter Sunday 2014 he has not had a seizure in 17 weeks. Knock on wood. I have never been so happy with a product. My days no longer consist of being home to watch him when he has them, and my nights do not consist of being woke every 3 hours to take care of him. I still worry they will start again every day but anything is better than it was.

Rated 5 out of 5 by from tablets are hassle-free Our Shih Tzu, Buster, has had seizures since he was about 16months old. We went through expensive and difficult medication regimes with him before we were able determine that he could not use phenobarbital. We have been able to control his seizures with KBr but in our area it is only available in liquid form - which he hates the taste and would fight to avoid his medicine. When we discovered that Pet Meds had liver flavored tablets we were overjoyed!!!! We simply break it up on top of his kibble and he eats it right up. We are so grateful that the tablets are also affordable from Pet Meds!

Rated 5 out of 5 by from This seems to work!! My 4 year old golden retriever began having severe seizures at age 3. I was familiar with seizures as I previously had a Irish Setter which I treated with Primidone. I did not want my golden to go through that. My vet prescribed Potassium Bromide and so far it has worked. He has had a couple of mild seizures but for the most part seizure free. Sort of expensive and long term so look to Pet Med to save you a little money.

Rated 5 out of 5 by from Love this place. My English Bulldog, Dumpling, was a puppy mill for the first two years of her life. After she was rescued, the shelter found out she suffered seizures. My wife and I feel in love with her at first site. The seizures did not matter to us when we adopted her. She has to be on medication for the rest of her life. One of which is called KBR. It's very difficult to find in my area. If you do find it, you have to take out a second mortgage to purchase. 1-800-PetMeds was recommended to us by friends. They always have the product in stock at a great price. I'm lucky to have found them.

Rated 5 out of 5 by from best purchase ever I love 800 Pet Meds. They are very helpfull. There is a genleman by the name of Ed that when you call he is wonderful. Gives you great service. This medicene helped my 11 year old WEImeraner with her seizures. Its a great product. I also buy all my prescriptions from 800 pet.

Rated 5 out of 5 by from Easy, effective treatment! My 4 year old, lab/pit mix has had epilepsy for 3 years. He was previously on phenobarbital but the time sensitivity (needing to be given every 12 hours on the dot) made it difficult for me to maintain. He used to have cluster seizures every 3-4 months and they increased in severity. Finally, we moved and got a new vet that prescribed K-BroVet Potassium Bromide, 750mg once daily. I'm happy to say that my little buddy hasn't had a seizure since January! I'm also very happy that 1800PetMeds carries this, at a significantly cheaper price than my vet's office!

Can i add the potassium bromide to his food?

Hi there, i just wanted to know I just started my collie on liquid potassium bromide. Since he is big dog that means that his dosage is rather large and he is not a huge fan of squirting it into his mouth. I wanted to know if it is okay to simply add the liquid to his dry kibble before he eats? Any feedback would be great.
Asked by: Gilbert
That is fine as long as you feel like he is getting the whole dose at once. Also, make sure you dont get any on you. You should wear gloves and/or wash your hands after administering and while cleaning his bowl.

I have a perscription for Zonisamide 100mg. Can this perscription work for this?

Asked by: bbrown
Although both medications can be used to treat seizures,they are not in the same drug class and therefore are not interchangeable. Speak to your veterinarian if this may be an option for your pet.

I am using a compounding pharmacy for my dogs potassium bromide

It is a 200 MG/ML oral solution and it is prescribed to give 1.5ML once daily. Can I use the tablets? And if I can how much would I give?
Asked by: Stacy
we carry the K BROVET TABLETS IN 250MG AND 500MG. The dose you are giving is 300 mg so the tablets are not a good option. We do carry K BROVET ORAL SOLUTION. It is butterscotch flavored. It may be an option for you. The strength is 250 mg per ml so to measure out 300 mg , You would give 1.2 ml of this solution. Ask your vet what they think. This may be a much cheaper option.
