How to prepare for an iron infusion

Before the day

Make sure your referral and recent iron studies are sorted with your GP first — the clinic needs these to confirm an infusion is appropriate. Tell the clinic about any allergies, previous reactions to iron, and any chance you could be pregnant, as this affects timing.

There's no need to fast. Eat normally and stay well hydrated on the day — being hydrated can make it easier for the nurse to place the cannula.

What to bring and wear

Wear comfortable clothing with sleeves that push up easily, since the infusion goes into a vein in your arm. Bring something to pass the time — the infusion takes about 15 to 30 minutes, with a further observation period afterwards, so allow roughly an hour at the clinic.

Bring a list of your medications and your Medicare card. If you've had a reaction to iron before, mention it clearly on arrival.

Plan for afterwards

Arrange for someone to drive you home, or plan to use a taxi or rideshare — some people feel lightheaded afterwards, so it's best not to drive yourself on the day. Keep the rest of your day gentle and avoid strenuous exercise for 24 to 48 hours.

Mild tiredness, headache or a metallic taste can occur and usually settle quickly. Your GP will often arrange a follow-up blood test around four to six weeks later to check your levels have responded. If you're booked for an infusion and unsure how to prepare, your GP can talk you through it.
