My cat's diarrhea and vomiting returned. Can I use old antibiotics?

Without seeing Z in person, I can't say what is the best course of treatment for him. I'd trust your vet's decision, but if you do have questions, you can always take him into another vet for a second opinion.

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 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 would recommend seeing the vet. At this point even if the diarrhea was initially related to the antibiotics Jasper may now have a disruption of his normal intestinal flora that requires additional treatment. It's also possible that the diarrhea is unrelated to the antibiotics and instead is due to intestinal parasites or a food sensitivity. If you wait until he stops eating or loses weight he may require more intensive treatment so I'd recommend making an appointment to see your veterinarian this week.

Hello, thank you for using Petco Pet Education Center, formerly Petcoach. I'm sorry to hear that Leo is having this problem. Many antibiotics cause gastrointestinal issues in cats so you will need to call your vet and let them know what is going on. Most likely they will have you stop one or both of the antibiotics and prescribe something different. I would also suggest that you put him on a pre/probiotic while he is taking antibiotics and then continue for at least one week after the antibiotics have been stopped. Hope this helps. Best wishes.

I'm sorry to hear that Turbo has not been feeling well! Yes, it is possible that he is vomiting due to gastritis caused by the antibiotics. Like humans, our four legged friends can also develop an upset stomach during antibiotic administration. Start by offering a bland diet small frequent amounts of boiled white meat chicken (no bones) in lieu of Turbo's normal diet. If Turbo's vomiting stops, continue feeding this for a few more days, then gradually transition to his normal diet over another 5-7 days. If Turbo's vomiting continues, call your vet to discuss possibly changing to different antibiotics to treat his ear infection. I hope that he's feeling better soon!

Kirito is adorable. Thanks for including a picture. I'm glad to hear that it sounds like he is already improving, but I would recommend giving the medication. Metronidazole is an antibiotic, but it specifically works well to decrease inflammation in the large intestine and help resolve diarrhea, so I would recommend giving it as directed to help resolve the diarrhea. Good luck! I hope that was helpful and that Kirito's diarrhea resolves soon. Thanks for using Petco Pet Education Center, formerly Petcoach.
