My dog has diarrhea, drinks lots, and won't eat after Cephalexin. Why?

Usually cephalexin is well tolerated by dogs, but it can cause nausea, vomiting, and diarrhea. This can be alleviated by giving Molly her medication with food, but to be safe, I'd give your vet a call to let them know she is having these side effects. They made decide to have you stop giving it, and may want to try a different medication. I'd give your vet a call now. Best of luck.

I would strongly recommend taking her right away back to your vet, antibiotics alone are definitely not enough when a dog is vomiting, she needs an injection to stop the vomiting to start with, otherwise no oral medications can be given. cephlaxin is also known for increasing vomiting, she needs a different antibiotic such as Metrogyl or Amoxicillin. i would also recommend a blood test at the very least.

Poor Gabrielle! I recommend giving the cephalexin with food to help minimize the risk of vomiting. I also recommend you let your vet know that Gabrielle vomited, as they may recommend adding a probiotic to her food to help reduce the risk of gastrointestinal upset. They may also recommend a different diet while she's on the cephalexin, or changing the medication if the vomiting continues. I hope she feels better soon!

Hello. None of these medications are associated directly with problems in the kidneys, so it might be best to report this new finding to your veterinarian. Dahlia may need some follow-up diagnostics to make sure this is not a new symptom. Thanks for contacting Petco Pet Education Center, formerly Petcoach.

Thank you for using Petco Pet Education Center, formerly Petcoach! Cephalexin is a commonly used antibiotic and has minimal side effects. Most of the side effects have to do with intestinal signs - mild nausea, diarrhea, or decreased appetite - all of these can be causing Chicharito to be a little bit less active. In rare cases, cephalexin can cause kidney damage, but this is in dogs who already have kidney disease. I hope this helps and am happy to answer any other questions you may have regarding your pets medications!

Hi there and thank you for using Pet Coach to address your concern. At the high end of the dose of 60mg/kg for systemic infections, it would be approximately 436mg every 8 hours for that dose for a 16lb dog. A 500mg capsule will not likely cause any life threatening problems. You may see vomiting and diarrhea but this should resolve on its own. If you start to see neurological symptoms such as seizures or a wobbly gait, I would have a veterinarian examine KC. I hope this helps! Please let me know if you have any other questions or concerns and I would be happy to help further.

If she is still not eating then you should take her back to the vet for IV fluid therapy. And more diagnostics. Make sure they did bloodwork to check her kidneys. An abdominal X-Ray or ultrasound may help to diagnose the issue as well. If her kidney enzymes are elevated, that can make her nauseous and not want to eat. IV fluids will help to flush the kidneys. There are also special foods that can help with kidney issues like hills K/D food. If the kidney issue is for sure due to an infection, then hopefully the antibiotics will kick in soon. Sometimes it’s good to give cephalexin with another antibiotic like Baytril if it is a severe infection.
