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.

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.

PhenoB and Brovet together seem to have no effect on controlling my German shepherd seizures (once every week), 90lbs, takes 2 tabs of KBrovet and 1.5tabs twice of pheno. Any suggestions please..

Asked by: BRUCE
Thank you for your question. I'm sorry to hear that your pet's condition is being poorly controlled with their current medication regimen. Please relay this information to your veterinarian so that she or he may determine a different treatment plan that may be more effective. Other medications that can help with seizures include gabapentin and primadone. I hope this is helpful!

This medication is prescribed by my vet.  My question is first my dog will not chew them so I have to force feed them to him will they dissolve and work without being chewed?

Asked by: Harley
Proin does not have to be chewed to be effective. It is a liver flavored chewable tablet which makes it more palatable for dogs. If your dog is not chewing the tablet; however, break it into smaller pieces and feed it that way.

I have a dog that takes 1 grain of phenobarbitaln pills once a day, what dosage would I order for the equivalent of that?

K-Brovet may not be an appropriate substitute for your pet's seizure disorder. Consult your veterinarian for more information.

This is advertised as FDA approved yet when you look up the NDC Code: 49427-322-48 is appears it is not FDA approved. Can you please clarify? My basic research also shows that the FDA will not approve any potassium bromide use for dogs.

I have been told seizure medication will significantly shorten my 7 year old Lab's life.  Is this true?

Asked by: Moosiesmom
It would be best to consult with your veterinarian, but I would think that not controlling seizures could shorten your dog's lifespan as well. I have seen several dogs die as a result of uncontrolled seizures that occur back to back.

Border collie takes 1 1/2 tabs of 500 mg potassium bromide and 2 1/2 tabs of 64.8 mg of phenobarbital per day. No seizures for 1 1/2 years. Can I reduces dosages?? He is 8 yrs old in good health

Asked by: Tedi
Hello Tedi, thank you for your question. I'm happy that the medications are working to control the seizures. Reducing dosages can be very tricky and must be done with caution because we definitely do not want to bring on a seizure. I would recommend keeping your dog on the medications until you speak to your vet about reducing the dose.
