Hello & welcome, I am Dr. B, a licensed veterinarian and I would like to help you with your wee one today.
How long ago did he have the Gabapentin?
How much does he weigh?
He had his 50mg last dose about 3 hours ago. He is now about 4.5Kg I think.

Thank you,Unfortunately, he is on a very high dose of Gabapentin and this will be reaching peak effect in the next hour. Therefore, we'd not want to give what is also a very high dose of Bupenorphine. The two together would risk severe depression of the nervous system and depress his heart and breathing rate. Therefore, if he is painful with just the Gabapentin, it would be better to ring your vet's our of hours number to see if they can dispense more of what we know he can safely tolerate with the Gabapentin. Otherwise,we'd have to wait another 5 hours before we'd want to switch to Bupenorphine (a better pain relief option for the pancreas between the two) and if we did, the dose would need to be no more then 0.3ml.Please take care,Dr. B.
