Strange reaction to sedatives

[smozes]

We’ve observed that our cat reacts to two different sedatives in the same, unexpected way: she sits and stares with dilated pupils and won’t sleep, even for days.

We first saw this with Buprenorphine, and now with Gabapentin. Is this common? What should we do?

To clarify, these were used as pain meds, just 1ml every 12 hours. Currently on Gabapentin, she is definitely sedated but is responsive. Won’t close her eyes and sleep though.

Have you discussed this side effect with the vet? What is the reason for the need of sedatives?
