What is Injectafer?

Injectafer is a dextran-free iron replacement product that is administered directly into the vein.

It was designed to gradually release iron once inside the body, which may decrease the potential for some side effects and conveniently give you more iron in just 2 administrations.

Injectafer dosing information

If you weigh less than 110 pounds, you may be given a smaller amount of Injectafer. Your doctor will decide on the most appropriate way to give you your treatment:

  • By injection, directly into a vein
  • By infusion, diluted in normal saline and given directly into a vein

Each Injectafer infusion takes about 15 minutes. After your infusion, your healthcare provider will monitor you for signs and symptoms of an allergic reaction—usually for about 30 minutes. Click here to learn more about what to expect at an infusion center.

If you are at risk for low serum phosphate, your doctor may monitor your serum phosphate levels if you require a second course of treatment of Injectafer (beyond 2 administrations of up to 750mg each). Your doctor can discuss risk factors for low serum phosphate with you.

IV iron may be an option when oral iron fails.

IV iron may be an option when oral iron fails.


Oral iron is typically taken in 300 mg or 320 mg tablets 3-4 times a day. The body is unable to absorb that much iron in the digestive tract at one time, so iron repletion may be possible in smaller oral iron doses over time.

With Injectafer, there is no daily oral iron routine

If you fail on oral iron, Injectafer is an IV iron option that can restore iron levels up to 1500 mg in 2 doses of up to 750 mg each, at least 7 days apart

Your doctor prescribed Injectafer, an IV iron, because iron pills were not suitable for treating your iron deficiency anemia (IDA). There are 2 reasons this may be:

  • Oral iron treatments haven't worked for you—there are various reasons this could be. One reason could be that your digestive system is having trouble absorbing it 
  • You were unable to tolerate the side effects related to oral iron treatment

Injectafer is also used to treat IDA in adults with chronic kidney disease who are not receiving dialysis.
Injectafer is not indicated to treat the symptoms of IDA.
