Brand Names: Ferate, Fergon

Generic Name: ferrous gluconate (Pronunciation: FER us GLOO koe nate)

What is ferrous gluconate (Ferate, Fergon)?

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.

What are the possible side effects of ferrous gluconate (Ferate, Fergon)?

Get emergency medical help if you have any of these signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat.

Call your doctor if you have serious side effects such as:

  • bright red blood in your stools; or
  • pain in your chest or throat when swallowing a ferrous gluconate tablet.

Less serious side effects may include:

  • constipation, diarrhea;
  • nausea, vomiting, heartburn;
  • stomach pain, upset stomach;
  • black or dark-colored stools or urine; or

Overdose symptoms may include drowsiness, severe nausea or stomach pain, vomiting, bloody diarrhea, coughing up blood or vomit that looks like coffee grounds, shallow breathing, weak and rapid pulse, cold or clammy skin, blue lips, and seizure (convulsions).

Ferrous gluconate is only part of a complete program of treatment that may also include a special diet. It is very important to follow the diet plan created for you by your doctor or nutrition counselor. You should become very familiar with the list of foods you should eat to make sure you get enough iron from both your diet and your medication.
