What is iron supplement used for?

Your body uses iron to make haemoglobin, the part of red blood cells that carries oxygen. Iron can become low after heavy menstrual bleeding, pregnancy, blood loss, limited dietary intake, or a problem absorbing nutrients. Low levels may contribute to tiredness, weakness, headaches, pale skin, shortness of breath on exertion, or a fast heartbeat, although these symptoms can have other causes. A blood test helps distinguish low iron stores from anaemia and guides the treatment plan. The product may be a tablet, capsule, liquid, or another prescribed form.

Use the dose and schedule provided by your clinician. Iron can cause nausea, constipation, abdominal discomfort, or dark stools. Tell your clinician if side effects make it difficult to continue; a different preparation or schedule may be suitable. Keep iron away from children, because an accidental large ingestion can be dangerous. Mention antacids, thyroid medicine, antibiotics, and other supplements, since iron can affect how some medicines are absorbed. [Iron Supplement](/materials/iron-supplement/) and [Iron Therapy](/treatments/medical-gynaecology/iron-therapy/) explain related options.

Seek urgent help for severe breathing difficulty, fainting, chest pain, vomiting blood, or signs of a serious allergic reaction such as facial swelling or trouble breathing. Contact your clinician if fatigue or breathlessness is worsening, bleeding continues, or treatment causes persistent vomiting or severe abdominal pain. Follow-up blood tests may be needed to check whether the plan is working and whether another cause needs attention.
