What is ferrous sulfate?
Ferrous sulfate is a type of iron. You normally get iron from the foods you eat. In your body, iron becomes a part of your hemoglobin (HEEM o glo bin) and myoglobin (MY o glo bin). Hemoglobin carries oxygen through your blood to tissues and organs. Myoglobin helps your muscle cells store oxygen.
Ferrous sulfate is used to treat iron deficiency anemia (a lack of red blood cells caused by having too little iron in the body).
Ferrous sulfate may also be used for other purposes not listed in this medication guide.
Before using this medication, tell your doctor if you are allergic to any drugs or food dyes, or if you have:
- iron overload syndrome;
- hemolytic anemia (a lack of red blood cells);
- porphyria (a genetic enzyme disorder that causes symptoms affecting the skin or nervous system);
- thalassemia (a genetic disorder of red blood cells);
- if you are an alcoholic; or
- if you receive regular blood transfusions.
If you have any of these conditions, you may need a dose adjustment or special tests to safely take ferrous sulfate.
It is not known whether this medication could be harmful to an unborn baby. Tell your doctor if you become pregnant during treatment.
It is not known whether ferrous sulfate passes into breast milk or if it could harm a nursing baby. Do not use this medication without telling your doctor if you are breast-feeding a baby.
Do not give ferrous sulfate to a child without the advice of a doctor.
Avoid taking any other multivitamin or mineral product within 2 hours before or after you take ferrous sulfate. Taking similar mineral products together at the same time can result in a mineral overdose or serious side effects.
Avoid taking an antibiotic medicine within 2 hours before or after you take ferrous sulfate. This is especially important if you are taking an antibiotic such as ciprofloxacin (Cipro), demeclocycline (Declomycin), doxycycline (Adoxa, Doryx, Oracea, Vibramycin), levofloxacin (Levaquin), lomefloxacin (Maxaquin), minocycline (Dynacin, Minocin, Solodyn, Vectrin), norfloxacin (Noroxin), ofloxacin (Floxin), or tetracycline (Brodspec, Panmycin, Sumycin, Tetracap).
Certain foods can also make it harder for your body to absorb ferrous sulfate. Avoid taking this medication within 1 hour before or 2 hours after eating fish, meat, liver, and whole grain or "fortified” breads or cereals.
Avoid using antacids without your doctor’s advice. Use only the specific type of antacid your doctor recommends. Antacids contain different medicines and some types can make it harder for your body to absorb ferrous sulfate.
