Dear Ziad,
You know most patients get 75 mg Vidaza per kvm body surface. You can calculate your father's body surface if you know his height and weight:
http://www.ultradrive.com/bsac.htm. When I use this calculator it shows that I should take 130 mg Vidaza/day so I don't think 140 mg is a high dose.
Good that he is getting blood and platelets! How about Neupogen injections for low white blood cells?
Kind regards
