Typical dosage for Injectafer
Iron-deficiency anemia (IDA)
- For people weighing 110 pounds (50 kg) or more: Each treatment course is typically a total dose of 1,500 mg that's injected into the vein (intravenously or IV). This total dose is given as two 750-mg injections separated by at least 1 week. Alternatively, adults can receive a one-time injection of 15 mg/kg of body weight (up to a maximum of 1,000 mg) for their treatment course.
- For people weighing less than 110 pounds (50 kg): Each treatment course is a total dose of 15 mg/kg of body weight, given IV as two doses separated by at least 1 week.
Iron-deficiency in adults with heart failure
- The dosage and number of infusions you need depend on your weight and your hemoglobin levels. Ask your provider how many infusions you need.
- For adults weighing 154 pounds (70 kg) or more: The typical dose is 500 mg or 1,000 mg given IV on day 1 of treatment. If you need a second infusion, it will be given 6 weeks later at a dose of 500 mg.
- For adults weighing less than 154 pounds (70 kg): The typical dose is 500 mg or 1,000 mg given IV on day 1 of treatment. If you need a second infusion, it will be given 6 weeks later at a dose of either 500 mg or 1,000 mg.
- Your provider might give you 3 additional doses (a 500-mg dose given every 12 weeks). This depends on your blood test results that give your provider information about your iron levels.
You might need to repeat a treatment course of Injectafer if your IDA or iron deficiency comes back.
