I have the chest pain too, one doc says its inflamation in my chest other says its anxiety. Although I never had until recently. My CD is in a flare that doesnt want to go away so they keep uping my Asacol. I never had till they upped my Asacol. So I am thinking it is either from the Asacol or my CD.
This is what is listed on the Asacol websit for side effects for the Professionals
Cardiovascular
Cardiovascular side effects have included chest pain of unknown etiology (3%) and vasodilation (up to 2% or greater). Infrequently, tachycardia, hypertension, hypotension, palpitations, pericarditis, pericardial effusion, myocarditis (rare), T-wave abnormalities (rare), severe symptomatic sinus bradycardia (at least 1 case), and pleuropericarditis (at least 1 case) have been reported. Angioedema, myocarditis, and pericarditis have been reported during postmarketing experience.
So I ask this how many of you are on Asacol?
