Ferrous

Common use

Ferrous (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 and myoglobin. 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).

Dosage and direction

Use ferrous sulfate exactly as directed on the label, or as prescribed by your doctor. Take on an empty stomach, at least 1 hour before or 2 hours after a meal. Swallow the tablet whole and do not crush, chew, or break it.

Precautions

Ask a doctor or pharmacist if ferrous sulfate is safe to use if you have ever had: iron overload syndrome; a red blood cell disorder such as thalassemia; or a condition for which you receive regular blood transfusions.
Ask a doctor before using this medicine if you are pregnant or breastfeeding.
Do not give ferrous sulfate to a child without medical advice.

Contraindications

Ask a doctor or pharmacist if it is safe for you to take ferrous sulfate 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.
Avoid taking other iron supplements. Do not take any vitamin or mineral supplements without asking a doctor or pharmacist.
