I have been on that med for 5 years from the VA and was specifically told to swallow whole. I take my dose, 30mg in the AM and have been very happy with the results.
I do know that stress induced angina is very hard to diognose but my Dr ruled out heart issues, after my initial problems, and I have reduced my stress and been angina free for almost 2 years now.
I know angina is very scary and painful and I know also that my relationship with God
helps my stress very well. If I can help of if I have helped plz let me know.
