Absorption of iron inhibited by magnesium trisilicate, antacids or cholestyramine. With concomitant use of alcohol, toxic delirium and lactic acidosis have been noted.
Ferrous sulfate may interfere with the absorption of tetracyclines. Therefore, these drugs should be given two to three hours apart.
Concomitant use of niacin and nicotine has been reported to cause increased flushing and dizziness.
Since pyridoxine is noted to have effects on dopamine, drug interactions are possible. A drug interaction with levodopa is noted, but can be avoided if levodopa is given in combination with decarboxylase inhibitor.
Prothrombin times are decreased when ascorbic acid is used concomitantly with anticoagulants.
Concurrent administration of oral iron preparations may interfere with the oral absorption of some quinolone anti-infective agents (e.g. ciprofloxacin, norfloxacin, ofloxacin) resulting in decreased serum and urine concentrations of the quinolones. Therefore, oral iron preparations should not be ingested with or within two hours of a dose of an oral quinolone.
Drug-Food Interactions: Eggs inhibit iron absorption. Coffee and tea consumed with a meal or one hour after a meal may significantly inhibit the absorption of dietary iron. Its clinical significance has not been determined. Oral iron preparations should not be taken within one hour or two hours after ingestion of the previously mentioned.
