An iron infusion is the direct delivery of iron into the bloodstream through an intravenous (IV) drip. Unlike oral iron tablets — which must pass through the digestive system and are often poorly absorbed or cause side effects — IV iron bypasses the gut entirely, delivering therapeutic doses directly to where they are needed.
At Lambert Medical Practice, iron infusions are administered by a trained clinician in our Surbiton clinic. You are monitored throughout the procedure, which typically takes between 15 and 60 minutes depending on the formulation and dose required.
Iron is essential for producing haemoglobin — the protein in red blood cells that carries oxygen around the body. When iron stores become severely depleted, the result is iron deficiency anaemia: fatigue, breathlessness, brain fog, pale skin, hair loss, and reduced exercise tolerance.
An iron infusion may be recommended when:
At Lambert Medical Practice, our standard protocol involves two infusions* followed by a blood test — giving your body the iron it needs and then confirming the results are where they should be.
* 2 sessions is our standard protocol. Depending on your starting levels and how your body responds to treatment, additional sessions may be required. Your GP will advise based on your Week 6 blood test results.
Our team is happy to discuss whether an iron infusion is right for you before you book.

Blood loss during childbirth frequently causes significant iron depletion. IV iron restores energy levels quickly in new mothers without the GI side effects of oral tablets.
Coeliac disease, Crohn's, ulcerative colitis, and gastric bypass surgery all reduce iron absorption. IV iron bypasses the gut entirely.
Nausea, constipation, and stomach cramps cause many patients to stop oral supplements. An infusion delivers a full therapeutic dose in a single session.
Endurance athletes frequently develop iron deficiency due to high demands. An infusion restores ferritin levels faster than oral supplementation, supporting performance and recovery.
Optimising iron stores before planned surgery reduces risk of needing a blood transfusion. Post-operatively, IV iron corrects anaemia rapidly to support healing.
