Hello Dr. My mother has gone through angioplasty 1 month before and she has done her first checkup as well, since after a week of angioplasty, she got cough, we have informed Dr. about it and doctor has changed her medicine (Brilinta 90) to Plavix 75 also increased dytor 10 tablet from 1 time a day to 2 times a day, its now 2 days over she got little relief by 50% but still cough not 100% gone, kindly advice how long it will take to recover completely and is it due to medicine side effect or any other reason ? i am very much worried, kindly advice. Regards
