What is ferrous sulfate and how does it work?

Ferrous sulfate is an oral iron salt, sold under brand names such as Feosol, Slow Fe (Slow-Fe), Feratab, Fer-In-Sol, and MyKidz Iron. It supplies elemental iron, the mineral your body needs to make hemoglobin and carry oxygen in the blood. When your diet does not provide enough iron, or when iron is lost or poorly absorbed (for example from blood loss, pregnancy, or an inadequate diet), iron stores fall and iron deficiency anemia can develop. Ferrous sulfate replenishes those stores.

It is very commonly used during pregnancy for iron supplementation. Doctors sometimes also use iron replacement to treat iron deficiency that underlies restless legs syndrome. Ferrous sulfate comes as regular tablets, slow-release tablets, and liquid drops, so ask your pharmacist which form fits your needs.

How to save on ferrous sulfate with an Rx.com coupon

Ferrous sulfate is available over the counter, and a fully generic version is on the market, which already keeps costs low. Even so, prices vary from pharmacy to pharmacy, and some over-the-counter iron products are cheaper with a coupon or when your provider writes a prescription for them. An Rx.com coupon lets you compare the discounted cash price across nearby pharmacies before you buy.

Ferrous sulfate vs. other iron supplements

Ferrous sulfate is one of several iron salts. Others include ferrous gluconate and ferrous fumarate. Each contains a different amount of elemental iron per tablet, and some people tolerate one form better than another, so your pharmacist can help you match the dose. All of these work by replacing iron; the main practical differences are the amount of elemental iron and how your stomach handles them.

Iron deficiency sometimes travels with other nutritional shortfalls. Providers may also check for and treat deficiencies of folic acid or vitamin B12 (cyanocobalamin), which can cause their own forms of anemia. Only take what your provider recommends, and do not combine supplements on your own.

Safety, side effects, and interactions

All iron-containing products carry a mandatory pediatric warning: accidental iron overdose is a leading cause of fatal poisoning in children under 6. Keep ferrous sulfate out of reach of children, and if a child swallows it, call a poison control center or seek emergency care immediately. This required pediatric-poisoning statement is the only warning of its kind on the label; ferrous sulfate does not carry an FDA boxed warning beyond it.

Common side effects are stomach-related: constipation, stomach pain, nausea, diarrhea, and harmless dark or black stools. Liquid forms can also stain the teeth. Ferrous sulfate can reduce the absorption of, or interact with, several medicines, so separate dosing by about 2 hours from:

• Tetracycline and fluoroquinolone antibiotics
• Levothyroxine (thyroid medicine)
• Bisphosphonates (bone medicines)
• Antacids and calcium supplements, and tea, which reduce iron absorption

Vitamin C can increase how much iron your body absorbs. Use extra caution, and talk with your provider first, if you have hemochromatosis or iron overload, hemolytic anemia, or a history of GI bleeding.
