My dog stopped vomiting. When can I stop giving her Zofran?

Updated On September 23rd, 2025

Pet's info: Dog | Italian Greyhound | Female | spayed | 10 years and 2 months old | 14 lbs

So my Italian greyhound Lola had severe vomiting yesterday and it has now been a full 24 hrs since she last threw up. She's feeling better and has been eating small meals throughout the day. It was told to me by a vet to give her zofran that I already had at home (4mg every 12 hours), but I wasn't told for how long. She's now had 3 doses. I can't get in touch with my vet because of the holiday weekend. I just wasn't sure when to stop. She does have PLN/Glomerulonephritis.

If it has been over 24 hours since Lola vomited I think I would give one more dose of zofran and then discontinue the medication. As long as she is eating normally and does not continue to vomit I don't think you have much to worry about. However, if the vomiting starts again you may want to restart the zofran and have Lola examined by an emergency veterinarian (especially with her history of PLN). I hope Lola continues to feel good and you have a good holiday weekend!
