My cat vomits sucralfate for GI bleeding. What's the alternative?

Updated On September 23rd, 2025

Pet's info: Cat | American Shorthair | Male | 11 lbs

My cat has GI bleeding due to an ulcer (blood in his stool), my vet prescribed sucralfate but it made my cat vomit about an hour and a half after him taking it, and he threw up his food. Is there an alternative to sucralfate? and why does this medication cause him to throw up? and should I stop giving it to him?

I'm sorry to hear that Chance is having all of these troubles. I do not usually have patients that vomit on sucralfate. The medication works best if even on an empty stomach and separate from any other medications he may be taking. I like to have owners give it as a slurry. The tablet will dissolve in a syringe of water and can be given that way. I would try these suggestions before stopping the medication. If he continues to vomit, your veterinarian can prescribe a medication for nausea or another GI protectant instead of sucralfate. I hope this information helps!
