Customer Question

We just mistakenly gave 16.2mg of phenobarbital to the wrong dog. The dog who received it is 24 lbs and takes .5mg of pred once a day, and PPL twice a day. He is an extremely well managed Addisonian, gets .6 CC of DOCP every 28 days, he is in the middle of his cycle. Should we be concerned?

You'll find that 16.2 mg (1/4 grain) of phenobarbital in a 10.9 kg (24 lb) dog - 1.49 mg/kg - will simply act as a sedative and nothing more. That dose is just a bit higher than the smallest initial dose recommended for treatment of idiopathic (unknown cause) epilepsy. The phenobarbital might transiently lower Fred's prednisone concentration but not to the extent that his Addison's will become unregulated.

Please respond with further questions or concerns if you wish.

Thank you!!! We will keep an eye on him and if he gets too lethargic I can always give a little pred boost. Thank you so much
