My cat has diarrhea, vet prescribed metronidazole. Is it right?

It could be that the diarrhea worsening is independent of the metronidazole as this drug does not help all cases of diarrhea, dependent on the cause. But since it is new it would be best to stop until you can speak with your vet. Has your kitty had a work up for these symptoms? Chronic vomiting and diarrhea are common symptoms of several things, but most notably GI disease. It would be abnormal for a cat to need chronic medication for vomiting unless there is a disease process there. Just to help a little, a work up for an older kitty with these signs could include bloodwork with thyroid testing, an abdominal ultrasound, and sampling if needed (dependent on ultrasound). If there is an underlying disease that can be treated your kitty may feel better and need less medications eventually. I hope this helps and thank you for using Petco Pet Education Center, formerly Petcoach!

I am sorry Damian does not feel well. I would recommend recontacting the vet to let them know Damian feels worse. Typically metronidazole works with in 24-48 hours. Typically if he is having liquid diarrhea he is not constipated. I would make sure a fecal is negative for parasites like coccidia. He might need deworming for coccidia since he is you. I would feed him the new food and you can start with a small amount of pedialyte however if he is still not improving I recommend taking him back to a veterinarian for more testing like bloodwork.

I wouldn't be too hard on the vet in this case, because shelter vets are quite used to treating these cases and metronidazole kills most of the offenders for causing diarrhea. You are right to be concerned about dehydration and how quickly the treatment should work. In most cases the diarrhea will improve within a day of starting treatment. It may be 3-5 days before his stools are back to normal though. If the explosive diarrhea continues for longer than a day after starting treatment and/or the kitten seems to be very depressed/inactive, then it would be best to return him to the shelter. There are some cases that require hospitalization, but I can assure you that most are treated well at home with the prescribed protocol. For now, I recommend following the veterinarians directions and calling the vet tomorrow if he seems to not be getting any better, or seems to be getting worse.

I don;t recommend to start an antibiotic unless it is confirmed there is a bacterial or protozoal problem. When antibiotics are used without just cause, that's how antibiotic resistance can develop.

Hello, sorry to hear about Magic. This medication is occasionally given long term and is generally a safe medication. It is originally an antibiotic with some anti-diarrhea and anti-inflammatory properties. Typically, for diarrhea this medication is given for up to 10 days then discontinued. Hope this helps and best of luck.

Hi and thank you for using PetCoach. I am sorry to hear that Beau is having diarrhea. Since, Beau has only been on metronidazole for one day, I would continue it as it may not have started to work yet. It typically takes 24-48 hours to see any changes. However, if Beau stops eating, is lethargic or has blood in his stool, I would reach out to your veterinarian again and let them know. Beau may need another physical exam or other medications.

Metronidazole is a drug that is best given every 12 hours to be effective and that is what is stated by research performed on how it works in the body. If pilling him is too difficult you can try a liquid formulation or even consider not using it at all and trialing a probiotic or bland diet.
