My father's cardiologist advised him take Coralan 5 mg and flavedon Mr. in addition to other heart medicines he is already taking. In 2016 he had angiography done in which there was 70% blockage, so Dr. just prescribed heart medicines to him. Now along with these extra medicines Dr. has also advised for angiography done again but till then advised those two medicines. After taking those two medicines for two days, he is feeling extreme restlessness, pressure in chest, extreme gastric problem, high bp and weakness. Is this can be due to these medicines or due to worsening heart condition. Should we continue these medicines or not. Please advise.
