I underwent angioplasty three years back in September 2012. I was prescribed ecosprin 75 and clopitab 75. But last year I suffered from internal bleeding and black color stool started coming out on five different occasions after every two months. Last episode of black colored stool happened in Dec. 2014. Now I am taking 37.5 mg ecosprin and clopitab 75 daily and razo 20 twice a day.now my doctor has advised to stop ecosprin and continue with clopitab 75 daily. Should I stop ecosprin 37.5 mg for ever? Please advise.
