Ferinject
Ferinject is an iron-containing medicine used to treat iron deficiency when oral iron supplements are not effective or not tolerated, or when a quick iron boost is needed.
How to Use
Dosage
Your doctor will determine the exact dose of Ferinject you need based on blood tests; for adults and adolescents 14 years and older, a single dose is typically up to 1000 mg of iron, and for children 1-13 years, it's typically up to 750 mg of iron.
Method
This medicine is given directly into a vein as an injection, a drip (infusion), or during dialysis; it is never given under the skin or into a muscle.
The maximum recommended weekly dose is 1000 mg of iron for adults and adolescents 14 years and older, and 750 mg of iron for children 1-13 years, with additional doses given at least 7 days after the first if more iron is needed.

Show 4 more warnings
- Incorrect administration can cause skin irritation or long-lasting brown discoloration at the injection site; if this happens, the administration must be stopped immediately.
- Taking oral iron supplements at the same time as Ferinject may make the oral supplements less effective.
- Seek immediate medical attention if you experience signs of a severe allergic reaction, such as rash, itching, trouble breathing, wheezing, swelling of the lips, tongue, throat, or body, or chest pain.
- Tell your doctor if you experience increasing tiredness, muscle or bone pain (in arms, legs, joints, or back), as this could be a sign of low blood phosphate levels that might lead to bone softening.
