Iron Infusion

An iron Infusion may be recommended in the setting of iron deficiency.

Iron can be given orally but often patients experience side effects (stomach upsets, constipation) or there are situations when oral iron is ineffective.

The aim of the iron infusion therapy is to replenish body iron stores and to remedy anaemia, a reduced level of haemoglobin due to iron deficiency.  Having anaemia can make you feel tired and weak.


An iron infusion appointment takes approximately 1 hour.  The infusion itself only takes about 20 minutes, however, we monitor you for a short period after.

An intravenous cannula is inserted into the arm for the duration of the procedure and then removed at the end.

Vital signs (blood pressure, pulse and oxygen levels) are monitored throughout the procedure.

Side effects and severe reactions are very rare.  However, you should be aware that they might occur.

The most common side effects are;

  • headache
  • dizziness
  • hot flushes
  • nausea
  • a reaction where the needle is inserted (the site of the infusion)
  • muscle spasms or muscle pain are uncommon

You should tell your doctor or nurse if you have had an allergic reaction to iron infusions in the past.

There is also a small risk of permanent skin staining at the site of the infusion.  Skin staining occurs when the infusion leaks into the surrounding soft tissues.

You may drive yourself to / from the appointment.

Iron infusions are considered safe to use in the second and third trimester of pregnancy.


  • Please ensure you have had adequate food prior to the procedure.
  • Drink plenty of water.
  • Send through your script for Ferinject at least 24 hours before your appointment so MGIU can arrange the script for your arrival.
