Ferrous Sulfate (Iron) (patient information)

IMPORTANT WARNING
Accidental overdose of products containing iron is a leading cause of fatal poisoning in children under the age of 6. Keep this product out of the reach of children. In case of an accidental overdose, call your doctor or a poison control center immediately.

Why this medication is prescribed
Ferrous sulfate provides the iron needed by the body to produce red blood cells. It is used to treat or prevent iron-deficiency anemia, a condition that occurs when the body has too few red blood cells because of pregnancy, poor diet, excess bleeding, or other medical problems.

This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.

How this medication should be used
Ferrous sulfate comes in regular, coated, and extended-release (long-acting) tablets; regular and extended-release capsules; and oral liquid (syrup, drops, and elixir). Ferrous sulfate usually is taken three times a day between meals. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take ferrous sulfate exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Although symptoms of iron deficiency usually improve within a few days, you may have to take ferrous sulfate for 6 months if you have severe iron deficiency.

This medication should be taken on an empty stomach, at least 1 hour before or 2 hours after eating.

Ferrous sulfate drops come with a special dropper for measuring the dose. Ask your pharmacist to show you how to use it. The drops may be placed directly in the mouth or mixed with water or fruit juice (not with milk).

Do not crush or chew regular, coated, or extended-release tablets, and do not open regular or extended-release capsules; swallow them whole.

Special precautions
Before taking ferrous sulfate:
 * tell your doctor and pharmacist if you are allergic to ferrous sulfate, tartrazine (a yellow dye in some processed foods and drugs), or any other drugs.
 * tell your doctor and pharmacist what prescription and nonprescription medications you are taking, especially chloramphenicol, cimetidine (Tagamet), levodopa (Larodopa, Sinemet), methyldopa (Aldomet), penicillamine, and vitamins. If you also are taking cinoxacin (Cinobac), ciprofloxacin (Cipro), demeclocycline, doxycycline, enoxacin (Penetrex), levofloxacin (Levaquin), lomefloxacin (Maxaquin), methacycline, minocycline, nalidixic acid (NegGram), norfloxacin (Noroxin), ofloxacin (Floxin), oxytetracycline, sparfloxacin (Zagam), or tetracycline, take it 3 hours after or 2 hours before taking ferrous sulfate. Do not take antacids at the same time as ferrous sulfate; take them as far apart as possible.
 * tell your doctor if you have or have ever had ulcers, colitis, or intestinal disease.
 * tell your doctor if you are pregnant, plan to become pregnant, or are breast-feeding. If you become pregnant while taking ferrous sulfate, call your doctor.

Special dietary instructions
Fish, meat (especially liver), and fortified cereals and breads are good dietary sources of iron; emphasize them in a well-balanced diet.

What to do if you forget a dose
Take the missed dose as soon as you remember it. However, if it is almost time for the next dose, skip the missed dose and continue your regular dosing schedule. Do not take a double dose to make up for a missed one.

Side effects
Ferrous sulfate may cause side effects. Your stools will turn dark; this effect is harmless. Your teeth may stain from the liquid; mix each dose with water or fruit juice. You may clean your teeth once a week by rubbing them with a small amount of baking soda.

Tell your doctor if either of these symptoms is severe or does not go away:


 * constipation
 * stomach upset

If you experience a serious side effect, you or your doctor may send a report to the Food and Drug Administration's (FDA) MedWatch Adverse Event Reporting program online [at http://www.fda.gov/MedWatch/report.htm] or by phone [1-800-332-1088].

Storage conditions needed for this medication

Throw away any medication that is outdated or no longer needed. Talk to your pharmacist about the proper disposal of your medication.
