My menstruation ended around Monday and I donated 450ml blood on Wednesday (yesterday). It was my first time donating blood and I slept for more than 10 hours last night but I am still feeling dizzy and headache. I am allergy to Bactrim, may I know which of these two are safe for me
Hi, dairy have gone through your question. I can understand your concern. Dizziness and headache is common.  No need to worry about that.  You will become normal within short time.  No need of ferrous fumarate or folic acid.  Your hemoglobin is normal. Because you can donate blood with normal hemoglobin only.  So no any treatment is required. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using Chat Doctor. Wish you a very good health.
