question: Hi my dad is 60yrs old & its been an year he is undergoing dialysis. But everytime its that his haemoglobin is going down. The doctors have told him to go for dialysis twice in a week & for every dialysis the doctor give him "injection name EFROX4000" to increase his heamoglobin. But this injection is not helping at all. I am too worried about my dad's health, please suggest me the best & safe option to increase his haemoglobin.
