I would say, based on my personal experience with taking Phenazopyridine, that it could certainly affect Chrone's disease. While Phenazopyridine has been great in calming bladder discomfort and calming bladder spasms, after two or more doses I notice an increase in GI motility and I experience intestinal spasms. I do not typically have a GI disorder, so I suspect if one did, their particular issue-such as Crohn's, would be aggravated.
