What is Injectafer?
Injectafer (ferric carboxymaltose) is an iron replacement product. You normally get iron from the foods you eat. Iron helps your body produce red blood cells that carry oxygen through your blood to tissues and organs.
Injectafer is used in adults to treat iron deficiency anemia (a lack of red blood cells caused by having too little iron in the body).
Injectafer is usually given after oral (taken by mouth) iron replacement medicines have been tried without success.
You should not use Injectafer if you have iron overload disorder, or anemia that is not caused by iron deficiency.
Before taking this medicine
You should not use Injectafer if you are allergic to ferric carboxymaltose, or if you have:
iron overload disorder (hemochromatosis, hemosiderosis); or
anemia that is not caused by iron deficiency.
To make sure Injectafer is safe for you, tell your doctor if you have:
liver disease; or
high blood pressure.
It is not known whether Injectafer will harm an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant.
Ferric carboxymaltose can pass into breast milk and may harm a nursing baby. Tell your doctor if you are breast-feeding a baby.
How is Injectafer given?
Injectafer is injected into a vein through an IV. A healthcare provider will give you this injection.
Injectafer is usually given in two doses, 7 days apart. Your doctor will determine whether you need a repeat course of these two doses.
Tell your caregivers if you feel any burning, pain, or swelling around the IV needle when Injectafer is injected.
You will be watched closely for at least 30 minutes after receiving Injectafer, to make sure you do not have an allergic reaction to the medication.
Tell your doctor if you have any changes in weight. Injectafer doses are based on weight, and any changes may affect the dose.
To be sure this medicine is helping your condition, you may need frequent blood tests. You may not notice any change in your symptoms, but your blood work will help your doctor determine how long to treat you with Injectafer.
