I have been prescribed ferrous sulfate for iron deficiency anaemia. Wierd thing is I have no symptoms at all and it was only picked up when I went to give blood. I was advised to go to GP and i had a blood test to confirm. She has prescribed me 200mg tablet 3 times a day however after reading on the internet about how irritable it can be on the stomach and because I have no symptoms can i just take it twice a day. Also do I take it with or without food. Leaflet says empty stomach but nhs website and one of the tv doctors say always take with food as is more easily absorbed, thanks in advancel
