What is the most important information I should know about ferrous sulfate?

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

What is ferrous sulfate?

Ferrous sulfate 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.

Ferrous sulfate is used to treat iron deficiency.

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

What should I discuss before taking ferrous sulfate?

Ask a doctor or pharmacist if this medicine 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.

How should I take ferrous sulfate?

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).

What happens if I miss a dose?

Take the medicine as soon as you can, but skip the missed dose if it is almost time for your next dose. Do not take two doses at one time.

Seek emergency medical attention or call the Poison Help line at 1-800-222-1222. Get emergency medical help if a child has accidentally swallowed a tablet. An overdose of iron can be fatal to a young child.
