Contraindications Ferrex 150 is contraindicated in patients with a known hypersensitivity to any of the components of this product.

Hemochromatosis and hemosiderosis are contraindications in the use of this dietary supplement.

Precautions This product contains FD&C Yellow No. 5 Lake (Tartrazine) which may cause allergic-type reactions (including bronchial asthma) in certain susceptible persons. Although the overall incidence of FD&C Yellow No. 5 Lake (Tartrazine) sensitivity in the general population is low, it is frequently seen in patients who also have aspirin hypersensitivity.

The type of anemia and the underlying cause or causes should be determined before initiating supplementation with Ferrex 150. Since the anemia may be a result of a systematic disturbance, such as a recurrent blood loss, the underlying cause or causes should be corrected if possible.

As with all oral iron preparations, Ferrex 150 should be stored out of the reach of children to protect against accidental iron poisoning.

Patients should not exceed the recommended dosage unless directed by a physician. Patients should be informed that iron products can cause dark or black stools.

Since oral iron products interfere with absorption of certain antibiotics, these products should not be taken within two hours of each other.

If pregnant, or planning to become pregnant or are currently breast-feeding please contact your physician, or health-care provider before using or continuing use.

Warning: Accidental overdose of iron-containing products is a leading cause of fatal poisoning in children under 6. Keep this product out of reach of children. In case of accidental overdose, call a doctor or poison control center immediately.
