Which is the max dose of Phenobarbital an epileptic dog can get?

Question

I have an 5 y.o. bichon who suffer for epilepsy since she was 8 month. I started with 15 gr tablets of phenobarbital, but over the years her condition got whorst and now I gave her 100 gr tablets. I wander which is the maximum dose I can give her?

Answer 1

I had a large (95 lb.) mixed breed who was epileptic from the age of 12 weeks.She started on one 100 grain tablet a day,but ended up taking 4 to 6 tablets a day as she got older,plus injectable Valium (20 mg.) when she had a severe seizure.Dogs develop a tolerance to barbiturates. Before my vet started my dog on the Valium,which I gave at home,I would have to take her to the vet when she would have a sever,prolonged seizure,for intravenous barbiturates.My vet said that my dog had built up such a tolerance that the amount of drugs she gave her to stop the seizure and keep her under for 12 hours would have killed a normal dog of her size! So,I don't know what the maximum dosage for a Bichon,but you could ask your vet.Also,if the phenobarbital isn't working,ask your vet to try your dog on potassium bromide,which will need to be compounded by a pharmacist.It is very inexpensive,and it worked wonders on my dog.She took it as well as the phenobarbital.My dog's seizures got less intense and less frequent as she grew older,and she lived to be 13,so maybe this will happen with your dog as well. Good luck.

Answer 3

"When considering just your dog's weight, the initial daily dosage is approximately 5 mg/kg which is (again approximately) about 2.3 mg/lb. Another way to look at this would be to double your dog's weight (2 mg/lb).

Example: if your dog weighs 30 lbs, the initial recommended daily dosage could be 2.3 mg PB x 30 lbs (the weight of your dog) = 69 mg/day. Or simply doubling your dogs weight (30 lbs in this example) would be 60 mg/day.

Therefore you could give your dog either a 30 mg tablet every 12 hours or split a 60 mg (grain) tablet and give a 1/2 grain every 12 hours.

As mentioned above in addition to considering the weight of your dog, the severity of the seizures is also taken into consideration..."

I hope that answers your question. If not, there is more provided in the link below.

Phenobarbital Dosage

Answer 5

Phenobarbital is given by prescription and their bodyweight is used to figure out the dosage.
you should call your vet to get the dosage allowed.

if your dog is still seizing after his regular dosage, there maybe another problem
I owned an epileptic dog, and they should also be on a preventative, which I know all too well is expensive.

please contact your vet.

good luck
