What is ferrous gluconate?

Ferrous gluconate 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 gluconate is used to treat iron deficiency anemia (a lack of red blood cells caused by having too little iron in the body).

Ferrous gluconate may also be used for purposes other than those listed in this medication guide.

Precautions

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);
  • liver or kidney disease;
  • if you are an alcoholic; or
  • if you receive regular blood transfusions.

If you have any of these conditions, you may not be able to use ferrous gluconate, or you may need a dose adjustment or special tests during treatment.

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 this medicine 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 gluconate to a child without the advice of a doctor.

Do not take any vitamin or mineral supplements that your doctor has not prescribed or recommended.

Avoid taking an antibiotic medicine within 2 hours before or after you take ferrous gluconate. 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 gluconate. 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 gluconate.
