The dose for preventing iron deficiency anemia is 300 mg once daily of ferrous sulfate.

DRUG INTERACTIONS: Antacids, H2-antagonists (for example, cimetidine, ranitidine, famotidine, or nizatidine), pancrelipase, and proton pump inhibitors (for example, omeprazole, lansoprazole, raberprazole, pantoprazole, or esomeprazole) may decrease the absorption of iron supplements.

Iron salts may decrease the blood concentration of bisphophonates (for example, aldendronate, etidronate, risedronate, or tiludronate), cefdinir (Omnicef), deferiprone (Ferripox), dolutegravir (Tivicay), eltrombopag (Promacta), levothyroxine (Synthroid), quinolone antibiotics (for example, ciprofloxacin, levofloxacin), and tetracycline antibiotics.

PREGNANCY: Ferrous sulfate crosses the placenta and is safe to use during pregnancy. All pregnant females should be screened for iron deficiency anemia and treated as necessary.

NURSING MOTHERS: Iron is normally found in breast milk. Ferrous sulfate is secreted into breast milk.

SIDE EFFECTS: The most common side effects associated with ferrous sulfate treatment are constipation, dark stools, stomach pain, nausea, and vomiting. Less common side effects include diarrhea, heartburn, and urine discoloration.
