Simbadol Is Causing A Bad Reaction

[Gizm0]

I posted on here a few days ago about my boy having a possible UTI. Well, we visited the vet today and was given antibiotics, anti-inflammatory meds, and he was given Simbadol.

After we got home and the medicine kicked in he started acting crazy. Running and hiding, afraid of me, then his mood would change and he would be happy and bouncing off everything, rubbing everywhere, then he’d change again and sit there and stare at the walls/objects for a extended amount of time. His eyes are the size of saucers, won’t use the litter box at all, he won’t eat, has not slept..I forced him to drink water just now (the vet said he MUST drink to flush his system) but he puts up a good fight and I can’t keep forcing him. I was able to give him about 6tbs of water.

How long do these reactions usually last? It’s been about 14 hours at this point. Is there anything I can try doing to calm him down? I feel like if he would just sleep it would help but I can’t get him to stop moving.

Hi. I don't know enough about this med to offer any input. But, I know others on this site have used various forms of buprenorphine (which is the generic name).
Until one or more of them read your post (and I hope that is soon) and can provide some first hand information, here is an article about its side effects.

I have never needed to use this medication on any of my cats, so won't be much help here, but I'm hoping since you posted late at night, that by now you have had a chance to talk to your Vet about this situation. If not, that's where I would start, because not only should they be able to help you, they should also be able to prescribe something else with less side effect for your little one.

There was a similar report here in November - then, on Sunday past, a new member posted an identical experience (post #10) - here you go: Simbadol (buprenorphine) Injection Bad Reaction

And, from 2+ years ago: Hyperactivity after Simbadol (Buprenorphine injection) - 17 y/o hurt cat supposed to be NOT mobile..
