Pet's info: Dog | Bedlington Terrier | Female | spayed | 6 years and 10 months old | 22 lbs
Polly has an anal abscess and is taking 10ml of meloxicam and Antirobe 150mg, she is eating and drinking, poo and wee as normal but she is very lethargic . She is a 10,7 kg dog and the 10 ml of meloxicam is given in a syringe Drew up to 10 ml level. She has been on this since Thursday . Is the lethargy a result of her medication?

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/

I am sorry Polly is not feeling well. I would call your vet and discuss the meloxicam dose. We do not use it at that high of a dose in the United States by they might in the U.K. However it is usually dosed by pounds. Do you think you are giving a 10lbs dose. If he is taking to much meloxicam it can cause gi upset but so can antibiotics. I just think the best option is to take Polly back to the veterinarian to discuss her being lethargic and meloxicam dose. Hope that helps

This is somewhat concerning, because he got about 3x the recommended dose and this class of drugs can quickly become problematic at high doses. However, it's possible that there will be no adverse effects from this. The most common adverse effect is vomiting, inappetence (stops eating), or diarrhea. If you notice this, or signs of lethargy or other abnormal behavior, then it will be best to take him to the vet fro an evaluation and treatment. For now, it's best to not give anymore meloxicam until you are able to contact the veterinarian that prescribed it. They will be able to better advise you on the best course of action. I hope that helps and all is well with Bob.
