Hi I am 26 and had a blood test 2 weeks ago and my iron levels are 2. I have been given iron supplements but I am just starting to get the headaches and dizziness now.  Which I think means the iron tablets may not be working.  I have to go back for another blood test in 2 weeks. Should I go back earlier and if my iron levels havent picked up should I ask for the injections? I also give blood regularly but am wondering how long I should wait to give again?
Hello, If iron level is very low, iron tablets may not be effective, and you might require intravenous iron supplementation or blood transfusions. Hope I have answered your query. Let me know if I can assist you further. Take care
