Common side effects during and immediately after
Most people feel fine during the infusion. Some notice a metallic taste, a brief feeling of warmth, or mild pressure at the cannula site. These effects are usually short-lived.
Immediately afterwards, it's common to feel a bit tired or washed out for the rest of the day. Some people experience a mild headache or slight nausea. These effects typically settle within hours.
Side effects the next day and a few days later
The day after your infusion, you might feel more fatigued than usual, or notice a mild headache, muscle aches, or slight nausea. Some people describe a 'flu-like' feeling for 24 to 48 hours. This is relatively common and usually settles on its own.
By three to five days after the infusion, most mild effects have passed and many people begin to notice their energy improving. If you develop a rash, swelling, difficulty breathing, or a fever, contact the clinic or seek medical advice promptly.
When to seek help
Mild side effects are normal and expected. However, you should seek medical advice if you experience persistent vomiting, a high fever, severe pain, spreading skin discolouration, or any symptoms of an allergic reaction.
Serious allergic reactions are rare with modern iron infusions but can occur. This is why infusions are always given in an accredited clinic with trained staff and emergency equipment.
