My father is suffering from dilated cardiomyopathy. He is taking multiple medicines including neopride total 40, digoxin, sacubitril valsartan, glycomet, ivabeat and ecosprin. I by mistake ordered neopride total sr instead of neopride total 40 sr. .can anything be done other than getting it exchanged? One pack can not even be exchanged because it is already open. Kindly suggest me what to do?
