As with any prescription-strength product containing folic acid, omega-3 fatty acids, iron, or vitamins D and E, please adhere carefully to the recommended dosages. Folic acid may obscure the diagnosis of pernicious anemia. Supplementation with omega-3 fatty acids should be avoided in patients with inherited or acquired bleeding diatheses, including those taking anticoagulants. Keep this and all iron-containing products out of the reach of children. See full Prescribing Information for complete usage and safety data.

The Recommended Dietary Allowances (RDAs) are established under the Institutes of Medicine (IOM) and state the amount of a nutrient that is needed for most people (97.5%) to stay healthy. They are specific to the age and gender of the person, including pregnant and/or breast-feeding women. RDAs are supplemented with a tolerable upper intake level (UL)–the largest daily amount of a vitamin, mineral, or other nutrient consumed or taken in that is unlikely to cause harm. Supplementation with DuetDHA^ec may require additional dietary intake of calcium, magnesium and vitamin E to meet the RDA.
