I Am A 43 Year Old Woman, Weighing 55kg, And

I am a 43 year old woman, weighing 55kg, and having a height of about 5ft 7inches. I have 4 children. I lost a lot of blood during the delivery of my third child and I was given blood transfusion. Ever since things have n been quite the same. There's even been instances of low blood pressure (50/90). I do not have appetite, and very thin. A pharmacist recommended cyprodine appetite enhancer and vitabiotics Feroglobin B12 (gentle liquid iron zinc,b complex). Is it okay to take both?
