I am Dr Mbong,
Iron has as one of its side effects nausea
, which symptoms vary from one person to the other and from one macnufacturer to the other. Nausea is worse with Iron syrups.
So the symptoms you are having may just be the side effects of the iron. To know if it is poisoning, the i will need to know how many tablets you are taking and the dosage of the Tablets. if you are taking just the numbe rof tablets your physician asked then you have no need to fear about iron poisoning
. Just take the required tablets and not more. Dont be in a haste to correct the low Iron or else you may overdose.
It is advisable to see the physician who prescribe the tablets and complain. He may prescribe some other form of Iron which is less nauseaous or which your body tolerates better.
Hope you recover from this and correct your low iron. By the way, alongside taking Iron tablets, eat iron rich foods like dark vegetables, beef (if you are not vegeterian), chocolate.
You may also need lab test to determine the cause of the anemia
and have it corrected. If it is from a bleeding ulcer, then having nausea on taking iron to correct the anemia will be more common.
