my 2 year old kid is in hospital for BMT and today its post transplant day 19 and his WBC fell from 6000 yesterday to 4000 today.. doctors started Cyclosporine orally but he is not taking it at all.. yesterday we mixed it with yogurt and then he took it with ease.. now i m afraid that this fall in WBC might be due to mixing medicine with yogurt?? his hb also fell to 7.6.. kindly guide me
