Therapeutic duplication warnings
Therapeutic duplication is the use of more than one medicine from the same drug category or therapeutic class to treat the same condition.
It can be intentional, when combining drugs with similar actions adds demonstrated therapeutic benefit — or unintentional, such as when a patient sees multiple prescribers or fills prescriptions at more than one pharmacy, which can lead to adverse effects.
Duplication:
Iron preparations
The recommended maximum number of medicines in the 'iron preparations' category to be taken concurrently is usually one. Your list includes two medicines belonging to the 'iron preparations' category:
- iron dextran
- Nu-Iron (iron polysaccharide)
Note: In certain circumstances, the benefits of taking this combination of drugs may outweigh any risks. Always consult your healthcare provider before making changes to your medications or dosage.
Food/lifestyle interactions
Moderate food/lifestyle interactions
Moderate:
iron polysaccharide Food/Lifestyle
Applies to: Nu-Iron (iron polysaccharide)
Adjust dosing interval
Concomitant use of some oral medications may reduce the bioavailability of orally administered iron, and vice versa. Food taken in conjunction with oral iron supplements may reduce the bioavailability of the iron. However, in many patients intolerable gastrointestinal side effects occur necessitating administration with food.
Management
Ideally, iron products should be taken on an empty stomach (i.e., at least 1 hour before or 2 hours after meals), but if this is not possible, administer with meals and monitor the patient more closely for a subtherapeutic effect. Some studies suggest administration of iron with ascorbic acid may enhance bioavailability. In addition, administration of oral iron products and some oral medications should be separated whenever the bioavailability of either agent may be decreased. Consult the product labeling for specific separation times and monitor clinical responses as appropriate.

Disease interactions
14 potential interactions Applies to: 12 conditions, including Allergies, Asthma, Rheumatoid Arthritis, Seizures, and Peptic Ulcer.
Achlorhydria
Moderate:
Nu-Iron
The iron polysaccharide in Nu-Iron has a moderate potential interaction with Achlorhydria.
Gastric acidity increases iron bioavailability by maintaining the ingested iron in a reduced form as ferrous ions, which are more readily absorbed than ferric ions. Therefore, when iron therapy is administered orally, higher dosages may be necessary for patients with decreased gastric acid production. Also, a liquid formulation is recommended in these patients because dissolution of the tablet coating depends on normal gastric acidity.
Allergies
Moderate:
iron dextran
Iron dextran has a moderate potential interaction with Allergies.
Hypersensitivity reactions, including anaphylaxis, have occurred after uneventful test doses as well as therapeutic doses of iron dextran injection, usually within the first several minutes of administration. Iron dextran should be administered cautiously in patients with a history of significant allergies and/or asthma. Epinephrine should be immediately available in the event of acute hypersensitivity reactions.
Asthma
Moderate:
iron dextran
Iron dextran has a moderate potential interaction with Asthma.
Hypersensitivity reactions, including anaphylaxis, have occurred after uneventful test doses as well as therapeutic doses of iron dextran injection, usually within the first several minutes of administration. Iron dextran should be administered cautiously in patients with a history of significant allergies and/or asthma. Epinephrine should be immediately available in the event of acute hypersensitivity reactions.
Blood Transfusion
Major:
iron dextran
Iron dextran has a major potential interaction with Blood Transfusion.
There is no excretory mechanism for iron. Iron will correct only hemoglobin abnormalities due to iron deficiency and should not be used to treat conditions such as thalassemia, hemosiderosis, hemochromatosis, normocytic anemia (unless iron deficiency exists), or in patients receiving blood transfusions. Clinical monitoring of erythropoietic function and ferritin levels is recommended.
Major:
Nu-Iron
The iron polysaccharide in Nu-Iron has a major potential interaction with Blood Transfusion.
There is no excretory mechanism for iron. Iron will correct only hemoglobin abnormalities due to iron deficiency and should not be used to treat conditions such as thalassemia, hemosiderosis, hemochromatosis, normocytic anemia (unless iron deficiency exists), or in patients receiving blood transfusions. Clinical monitoring of erythropoietic function and ferritin levels is recommended.
Cardiovascular Conditions and Disorders
Moderate:
iron dextran
Iron dextran has a moderate potential interaction with Cardiovascular Conditions and Disorders.
Cardiac toxicity such as chest pain and tightness, shock, hypertension, tachycardia and arrhythmia have occurred during iron dextran therapy. Hypotension and flushing have been reported and are thought to be infusion- rate related. Adverse reactions experienced following therapy with iron dextran may exacerbate cardiovascular complications in patients with preexisting cardiovascular disease, caution is advised.
Hemoglobinopathy
Major:
iron dextran
Iron dextran has a major potential interaction with Hemoglobinopathy.
There is no excretory mechanism for iron. Iron will correct only hemoglobin abnormalities due to iron deficiency and should not be used to treat conditions such as thalassemia, hemosiderosis, hemochromatosis, normocytic anemia (unless iron deficiency exists), or in patients receiving blood transfusions. Clinical monitoring of erythropoietic function and ferritin levels is recommended.
Major:
Nu-Iron
The iron polysaccharide in Nu-Iron has a major potential interaction with Hemoglobinopathy.
There is no excretory mechanism for iron. Iron will correct only hemoglobin abnormalities due to iron deficiency and should not be used to treat conditions such as thalassemia, hemosiderosis, hemochromatosis, normocytic anemia (unless iron deficiency exists), or in patients receiving blood transfusions. Clinical monitoring of erythropoietic function and ferritin levels is recommended.
Liver Disease
Major:
iron dextran
Iron dextran has a major potential interaction with Liver Disease.
Iron is transported in plasma complexed to transferrin, a beta1-glycoprotein synthesized by the liver. Iron is cleared from the plasma by the reticuloendothelial system (including liver) and excess stored as ferritin within the reticuloendothelial system and hepatocytes. Therapy with iron dextran should be administered with extreme caution in patients with severe hepatic dysfunction.
Neurological Disorders
Major:
iron dextran
Iron dextran has a major potential interaction with Neurological Disorders.
Iron dextran has induced neurologic toxicity such as seizures, paresthesia, weakness, disorientation, and unconsciousness. Therapy with iron dextran should be administered cautiously in patients with or predisposed to neurologic dysfunction.
Noninfectious Colitis
Moderate:
Nu-Iron
The iron polysaccharide in Nu-Iron has a moderate potential interaction with Noninfectious Colitis.
Iron can be irritating and damaging to gastrointestinal mucosa. Iron therapy should be administered cautiously in patients with peptic ulcer disease, enteritis, or ulcerative colitis.
Peptic Ulcer
Moderate:
Nu-Iron
The iron polysaccharide in Nu-Iron has a moderate potential interaction with Peptic Ulcer.
Iron can be irritating and damaging to gastrointestinal mucosa. Iron therapy should be administered cautiously in patients with peptic ulcer disease, enteritis, or ulcerative colitis.
Rheumatoid Arthritis
Minor:
iron dextran
Iron dextran has a minor potential interaction with Rheumatoid Arthritis.
Patients with rheumatoid arthritis may have an acute exacerbation of joint pain and swelling following the administration of iron dextran.
Seizures
Major:
iron dextran
Iron dextran has a major potential interaction with Seizures.
Iron dextran has induced neurologic toxicity such as seizures, paresthesia, weakness, disorientation, and unconsciousness. Therapy with iron dextran should be administered cautiously in patients with or predisposed to neurologic dysfunction.
