Why is my puppy vomiting after taking amoxicillin for a UTI?

Thank you for using Petco Pet Education Center, formerly Petcoach. I recommend contacting Annie’s veterinarian to discuss the appropriate antibiotic for her. Medication choice depends on what type of infection they found and if culture/sensitively was performed. Be sure to feed her before medication. In some cases smaller can be given more frequently, or different antibiotic or possibly a long lasting injection may be given if she can not tolerate oral medications Good luck I hope she’s better soon.

Antibiotics and urinary tract infections themselves can both cause nausea/vomiting. However, as you finished the antibiotics 5 days ago, it is less likely that the vomiting is due to the UTI antibiotics. If she has recently gotten table food or had access to food from the garbage, she may have a condition called pancreatitis caused by a sudden high fat meal that may cause vomiting, diarrhea, abdominal pain. A trip to your veterinarian for screening bloodwork to rule out a liver/kidney/pancreas issue as the cause of the vomiting, subcutaneous fluid therapy, anti-nausea medication (cerenia), and a prescription intestinal diet is advised. If you are not able to get an appointment immediately, I recommend feeding only a bland diet of boiled rice and chicken (with no regular kibble) for the next 3-5 days. Sometimes this alone helps resolve the symptoms of mild gastroenteritis. Good luck!

Hello and welcome to Petco Pet Education Center, formerly Petcoach. Vomiting can be caused by many different conditions including gastritis (upset stomach from eating something like garbage, raw food, bones, or dead animals in the park, etc.), pancreatitis, obstructions in the gut, as well as kidney/liver/metabolic diseases. Very often amoxicillin will do nothing to help the vomiting, and can make it worse as antiboitics are hard on the guts. I recommend feeding a bland diet of boiled/boneless/skinless chicken breast and boiled rice in small frequent meals (4-6 meals a day of 1/2 cup size meals). If the vomiting continues, or if Mui is lethargic or weak, then I would see a vet right away. If the vomiting stops and she is eating and acting normally then she is likely OK. I would not give any amoxicillin. Best of luck with Mui.

There is a chance that this is related to the medication and so should stop within about 12 hours of stopping the medication. If your puppy is still vomiting after that then I would recommend taking her in to be examined and given medication to stop the vomiting. I would also recommend withholding food from her for about 12-24 hours and see if that helps the vomiting stop. I hope this helps. Thanks for using Petco Pet Education Center, formerly Petcoach. Best of luck.

I'm sorry to hear that Romeo has a UTI! Amoxicillin is a very common broad-spectrum antibiotic that is commonly used in animals and people. In some individuals, it can cause an upset stomach with vomiting, diarrhea, and/or loss of appetite. For sensitive individuals, this could start after a day or two, but for others, they may have a bit of mildly soft stool near the end of their treatment course. Odds are good that Romeo will be absolutely fine with this medication! It's not a big deal if he has mildly soft stool for a few days. If this happens, just feed a bland diet of boiled white meat chicken and white rice for a few days before gradually mixing his normal food back in. However, if he refuses to eat or drink, or begins to vomit, stop the amoxicillin and call your vet to discuss switching to a different medication. I hope that everything goes well! https://www.petcoach.co/pet-medication/amoxicillin/

I'm sorry to hear that your little girl is not feeling well. For a UTI, that is an appropriate dose of Baytril. Unfortunately, Baytril, along with most other antibiotics, can cause vomiting. You can either try to give the pill with food or cut it in half and give half of the tablet every 12 hours. This way she still gets the full pill every day, but decreasing the amount given at one time may decrease the upset stomach she is experiencing. If she continues to vomit, I would recommend contacting your veterinarian as she may need to get a different antibiotic if she can't tolerate the Baytril.

First make sure she is eating her food without vomiting, give her only half of the food amount. if after an hour she seems to be ok and she is not vomiting, give her the second half of her food and the antibiotics. if she continues vomiting you will have to take her to your vet.
