I know that some people are allergic to aspirin. I was wondering, if you are not allergy to peptobismol, does that mean you are able to take aspirin and not have to worry about getting a drug reaction? My mom was allergic to aspirin so i'm kind of worried that I might get a reaction to aspirin if I take it. But I can take peptobismol fine and don't have any problems with it. I was wondering if anyone knew.
