My dog ate my meloxicam. Could this cause coughing blood and bile?

Hi! Thanks for using Petco Pet Education Center, formerly Petcoach! Katie just ingested a very high dose of meloxicam. The big problem with an overdose of meloxicam (or any other NSAID) is that it can definitively result in side effects such as gastrointestinal ulceration (which may manifest as black, tarry stools which basically means digested blood), kidney disease, liver disease and gastrointestinal signs such as vomiting, diarrhea and anorexia. I advice that you take Katie to a veterinarian (perhaps a bit farther from you) for evaluation and further treatment. If it has been less than 2 hours, vomiting could still be induced which could make the outcome better. If there is no way possible you can do that then take her first thing in the morning tomorrow. Good luck!

As long as the smaller dog doesn't have any pre-existing liver or kidney issues, its unlikely that this will be a problem. Watch for vomiting, diarrhea, or decreased appetite, or lethargy; if you notice any of these symptoms, take him to the vet for an exam and bloodwork. Again, though, based on what you are describing, as long as Bean is otherwise healthy, I think its extremely unlikely that this will cause any issues. Thanks for asking Petco Pet Education Center, formerly Petcoach!

It seems a little unusual for a single dose of meloxicam to affect Blanca after two weeks, but I suppose it is possible. I'd recommend having your vet examine the stool and Blanca. They might also recommend checking some lab work.

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. So sorry to hear that Goliath is having this issue. I would recommend you STOP giving the Meloxicam right away and I would honestly take him in to an emergency vet clinic to be seen right away. I think his dose of Meloxicam is quite high and it may be upsetting his stomach and could be causing some damage to his kidneys. With my calculations he should have been getting 7.5mg once a day, not twice. I would recommend he go in for some bloodwork to check his kidney values and get some additional medications to protect his stomach lining. If his kidney values are elevated he may need to be hospitalized so he can be on fluids to flush out his kidneys. I don't want to scare you but this could be a pretty serious issue. I wouldn't wait too long to have him seen. The longer you wait, the more damage that could be done to his body. I hope this was helpful. I am hoping for the best for Goliath. Dr. Amber

It is rare and not likely. Higher doses or sometimes associated with used before surgery are when that is a concern but usually the higher doses will damage kidneys or cause an ulcer before the other blood counts are affected.

Hello, Lola is indeed at higher risk for adverse reactions even after a single dose of meloxicam, however your veterinarian is likely not too concerned with the severity of her kidney disease. Therefore, the side effects of meloxicam to her kidneys would be dependent on how severe her kidney disease is. I would recommend monitoring her kidney values for the next five days as Meloxicam has a long half-life and can take up to 5 days to remove completely from the body. This could be done with daily blood checks. Also know that of all the NSAIDs, Meloxicam has the widest safety margin in the phase of kidney disease. Look for any signs of increased drinking, decreased urinations, lethargy, painful abdomen, vomiting, or a decreased appetite and have her evaluated immediately if you note any. Hope this helps and best of luck.
