A side effect of ranitidine is diarrhea, but I would give it to Oreo tomorrow on an empty stomach. If it does give him diarrhea again, then I would give your vet a call to let them know you are seeing this side effects, and the vet will let you know if they want you to continue with the ranitidine or want to try a different drug for Oreo.
