question: my father was diagnosed with CKD stage V and  is under dialysis thrice a week  since last 1 month. Doctor recommended Espogen 4000 thrice week. Per dialysis appox 1 ltr water is drained. I have 2 queries in this regard:\1) What it means to drain 1 ltr water, is it good or bad.2) Do we have to give the injection Espogen whole life????
