My cat is inactive, can't walk after Marbocyl. Is it an overdose?

Hi, I see you've posted again...you have confirmed that this is a massive overdose of meloxicam for a dog that size and it would definitely cause her to be lethargic. Overdoses are most concerning for causing stomach and/or intestinal ulcers/bleeding. It can also cause significant damage to the kidneys. For these reasons, I recommend you take Polly to the vet immediately. There are medications and treatments that can keep this from getting worse and it's imperative that they are given soon. However, it's worth double-checking the syringe. Liquid meloxicam is usually given with a small 1ml syringe. The 1ml may be written as 1.0ml, which could be confused with 10. A 10ml syringe is considerably bigger and would be quite difficult to give to a cat. Below is a link to a guide that explains the syringe sizes better: http://www.vgr1.com/metacam/

Hello. While this is not a huge overdose, it is a bit high for an 8-pound cat. Please double check with your veterinarian to see if he wants you to continue with this dose. Thanks for using Petco Pet Education Center, formerly Petcoach.

This represents a pretty substantial overdose. Corbett got about 2.5 times more than the highest published dose for pain relief. However, it's thought that buprenorphine has a high index of safety, and even large overdoses don't usually cause serious effects. I'm assuming you gave it on the gums ("transmucousally") as that's how it's typically prescribed for pain relief at home in cats. Because of that method of administration, there's no way to remove the drug from his system by inducing vomiting. There is a reversal agent that is somewhat effective, but may have to be given in multiple doses due to the way buprenorphine works. The drug is naloxone, and your veterinarian should have this drug. Because the signs of overdose can be concerning (vocalization, ataxia, hypersalivation, decreased body temperature, and lethargy) my best recommendation would be for you to take Corbett back to your veterinarian for administration of this drug, so that the overdosage can be averted.

Unfortunately this is a very large dose for his size. Also, if he has kidney problems he could be even more sensitive than normal cats. I would have your vet or your local emergency take a look at him. They may want to check his bloodwork to ensure his kidney values look okay and also make sure he is able to pass irons. If he is blocked and cannot urinate then This can also cause more issues with his kidneys. I hope this helps and he starts to feel better soon.

Was this increase something that your Vet suggested? If not I would absolutely drop the dose back down to what was prescribed. Giving too much can be dangerous. Always consult your vet before changing any medication doses. If your cat gets worse you should go to an emergency vet right away.

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! In the US we do not use Albendazole in dogs or cats. If Oscar only weighs 5.5 lbs and if he was given 5mls that is 200mg of albendazole and at that dose it has been reported to cause mental dullness and decreased appetite in cats. It can also affect white and red blood cells. I don't have much information about overdoses in dogs. Stop giving him the medication. The dose of ivermectin should be ok. If he gets worse or doesn't improve he should be taken to an emergency hospital. Good luck!

I would not be overly concerned, although the recommended dose is 5-10mg/lb (and an 8lb cat would have consumed approx 15mg/lb) it does have a wide safety margin and overdose symptoms are very rare. I would expect some mild gastrointestinal upset and a probiotic would be helpful to reduce the impact on the natural gut balance
