Sandy, I have been taking Enteric coated aspirin for the last 4+ years with no side effects. I had a stroke in 2006 and when I left the hospital, the Doctor told me I would be taking these at 1 per day for the rest of my life. They are nothing more than a coated, 325mg time release aspirin. They do not affect my shooting, but if you cut yourself, you will bleed a little longer than before. You will also bruise easier. Hope this info is of use to you. Larry Evans
