I swore that Aspirin and Tylenol were OK for UC. My mom scolded me for buying Aspirin today saying that it's definitely NOT recommended/allowed for UC patients. Google didn't help much. One article said low-dose Aspirin had no effect.
Guess it's back to taking Tylenol next time I get a migraine. I had a bad one yesterday and 2 extra strength Tylenol did nothing. I was desperate for some Aspirin, which I got today for future use...if allowed...
