My cat isn't peeing after vet visit; is Buprenorphine safe to use?

I am not sure how you are able to tell that he hasn't slept for 24 hrs unless you are also up yourself the entire time. Chances are he has slept somewhat, but these are still concerning symptoms that he may be having an adverse reaction to the medicaiton or that a lower dose is needed for him. Also it is concerning if he hasn't gone potty. Male neutered cats can get urinary blockages which causes them to be very vocal, lethargic and strain to urinate. I would advise taking him to your local vet right away for an evaluation and potentially stopping his medication until he is deemed healthy enough to proceed with either this medicaiton or an alternative. I hope that Cucho is able to make a full and speedy recovery. Best wishes and take care.

Thank you for contacting Petco Pet Education Center, formerly Petcoach with your question about Boo. The dose for cats can be up to 1mg/kg. 1mg/kg equals 0.001mg/l, or 1mg/ml. Based on this, he could have up to 4.8ml, so this is within the dose. I hope this helps!

Have you been giving him the buprenorphine? This could be making him very lethargic. If he doesnt seem really painful, you may consider stopping the pain meds or giving him a half dose to see if they helps to perk him up a bit. But if he is continuing to be lethargic despite not being on pain medication then I believe he needs to follow up with your vet to ensure nothing else is wrong. I hope he starts to feel better!

With pain relief medication the goal is to use as needed. So if you believe Roman is in pain or uncomfortable it is good to give him the medication, but you do not have to finish a course like with antibiotics. I would continue the buprenex as long as you feel that Roman is still in pain, and also the packaging label from the veterinarian who prescribed the pills should indicate how many days he believes Roman should take the pills. Bladder inflammation can take days to weeks to calm down so h may need the pills for longer. Thank you for using Petco Pet Education Center, formerly Petcoach!

I am sorry we couldn't get to your question earlier. Hopefully Sitara is back to normal now. The symptoms you have described are consistent with opioid use (which is what Buprenorphine is). I would not be overly concerned. I am more concerned about her dental disease and the plan to treat that, since the pain medications and antibiotics won't fix that particular problem. She needs a full dental cleaning under anesthesia and may need her teeth extracted if stomatitis is a concern. https://www.petcoach.co/article/gingivitis-and-stomatitis-in-cats/

Buprenorphine can be given as often as every 6 hours, but it's typically prescribed to be given every 8 hours. It can be difficult to know for sure whether a cat's in pain, but I would look for signs like a relaxed posture, not hiding, interest in food and attention as signs that Kiki is comfortable. If you give it every 6 hours you can be pretty confident that it's doing it's job.

If she is unable to pass any urine she needs to be seen immediately to prevent bladder rupture and may need a catheter to relieve the pressure and prevent nerve and muscle weakness. This is an emergency and should not be managed at home and causes severe pain and discomfort with potential life threatening complications
