A generic drug is a copy of the brand-name drug with the same dosage, safety, strength, quality, consumption method, performance, and intended use. Before generics become available on the market, the generic company must prove it has the same active ingredients as the brand-name drug and works in the same way and in the same amount of time in the body.
The only differences between generics and their brand-name counterparts is that generics are less expensive and may look slightly different (eg. different shape or color), as trademarks laws prevent a generic from looking exactly like the brand-name drug.
Generics are less expensive because generic manufacturers don't have to invest large sums of money to develop a drug. When the brand-name patent expires, generic companies can manufacture a copy of the brand-name and sell it at a substantial discount.
FeRiva 21/7® is a multivitamin / multimineral prescription dietary supplement indicated for use in improving the nutritional status of patients with iron deficiency.
FeRiva 21/7® has not been tested in children. Dosing for elderly patients should begin at the lower end of the dosing range. Talk to your doctor or healthcare provider before taking FeRiva 21/7® if you have a known sensitivity to any of its ingredients. Because some medications may interact with FeRiva 21/7®, you should tell your doctor or healthcare provider about any medications you are taking, including antacids and antibiotics. You should not take this product if you have ever been diagnosed with hemolytic anemia or an iron overload disorder such as hemochromatosis or hemosiderosis. If you have certain forms of anemia associated with vitamin B12 deficiency (i.e., pernicious anemia), the vitamin B12 contained in FeRiva 21/7® is not enough to treat your condition. Folic acid in doses above 1.0 mg daily can hide the symptoms of these anemias, so your doctor must rule them out before prescribing this product. Once you begin the FeRiva 21/7® 28-Day Iron Supplement Regimen, take one red iron tablet daily for 21 days, followed by 1 purple inert tablet for 7 days, with or without food, or as prescribed by your doctor or healthcare provider. Do not exceed the recommended dose. Some patients taking folic acid have reported allergic reactions. Contact your doctor or healthcare provider and discontinue use if you develop any unusual symptoms. Keep this product out of reach of children.

In case of accidental overdose, call a doctor or poison control center immediately.
