http://www.medications.com/se/Papain Recent side effects for Papain Mon, 11 Oct 2004 12:31:10 -0400 http://www.medications.com/effect/view/6134 The past three days I have been taking chewable papain after meals or after eating. I take atenolol for high blood pressure. Last night and today I feel like I have not taken any atenolol. I am wondering if the papaya enzyme has canceled out the atenolo http://www.medications.com/effect/view/6134
