FeroSul is a type of iron. You normally get iron from the foods you eat. In the body, iron helps your blood carry oxygen to tissues and organs and helps your muscle cells store oxygen.

FeroSul is used to treat iron deficiency.

FeroSul may also be used for purposes not listed in this medication guide.

Use only as directed. Tell your doctor if you use other medicines or have other medical conditions or allergies.

Use 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.

Measure liquid medicine carefully. Use the dosing syringe provided, or use a medicine dose-measuring device (not a kitchen spoon).

Swallow the tablet whole and do not crush, chew, or break it.

You may need to follow a special diet. Follow all instructions of your doctor or dietitian. Learn about the foods you should eat or avoid.

Store at room temperature, away from moisture and heat.

Ask a doctor or pharmacist if FeroSul is safe to use if you have ever had:

• iron overload syndrome;
