What are iron infusions?

An iron infusion is a treatment that gives your body extra iron through an IV (a small tube placed into a vein). Instead of taking iron pills, which go through your stomach, the iron goes directly into your bloodstream. This makes it easier for your body to use and helps restore low iron levels more quickly. At Thrive, we offer iron infusions in Ottawa and Surrounding area. 

Iron is important because it helps your red blood cells carry oxygen around your body. Without enough iron, you can feel tired, weak, dizzy, or short of breath. An infusion is like giving your body a boost of the iron it’s missing so you can start to feel better.

Why Might Someone Need an Iron Infusion?

Someone might need an iron infusion if their body doesn’t have enough iron and pills or diet changes aren’t helping enough. Low iron (called iron deficiency) can happen for many reasons—like heavy periods, pregnancy, digestive issues (where your body can’t absorb iron properly), or chronic illnesses.

If iron levels drop too low, people may feel exhausted, look pale, have trouble concentrating, get headaches, or feel short of breath. In more serious cases, low iron can cause iron deficiency anemia, which means your blood can’t carry enough oxygen. If you’re interested in starting the process, you can find more information on our dedicated page for all things iron infusions here. 

An iron infusion is often recommended when:

• Oral iron supplements cause stomach upset or don’t work well
• Iron deficiency is severe and needs to be corrected quickly
• Ongoing medical conditions make it hard to keep iron levels up

Signs and Symptoms of Low Iron

Constant fatigue – feeling tired even after rest

Weakness – muscles feel heavy or you get worn out quickly

Pale skin – especially noticeable in the face, lips, or inside the eyelids

Shortness of breath – feeling winded after light activity

Dizziness or lightheadedness – especially when standing up

Headaches – frequent or unexplained

Cold hands and feet – poor circulation from low oxygen levels

Brittle nails or hair loss – your body isn’t getting the nutrients it needs

Fast or irregular heartbeat – your heart works harder to carry oxygen

Restless legs – uncomfortable sensations in the legs, especially at night

Cravings for non-food items (like ice, dirt, or paper) – called pica and linked to low iron

How Iron Infusions Work

An iron infusion works by delivering iron directly into your bloodstream through an IV (a small tube placed into your vein). Since the iron bypasses your stomach and digestive system, your body can absorb it much more efficiently than with pills.

Once in your bloodstream, the iron attaches to proteins in your blood and gets carried to your bone marrow. That’s where red blood cells are made. With the extra iron, your body can produce more healthy red blood cells, which improves how well oxygen is carried throughout your body.

Over time (usually days to weeks), this helps increase your energy levels, reduce fatigue, and ease symptoms caused by low iron or anemia.

What to Expect During Treatment

Before the infusion

• Ensure you have eaten a light meal or snack.
• Stay well-hydrated; drinking water before your infusion is encouraged.
• Wear loose, comfortable clothing, especially with sleeves that can be easily rolled up.
• Inform us if you have any known allergies or reactions to previous IV medications.

Possible side effects

While most people tolerate iron infusions well, some may experience mild side effects. Common side effects include:

• A metallic taste in your mouth.
• Headache or dizziness.
• Mild muscle or joint pain.
• Nausea or upset stomach.
• Flushing (warmth or redness of the skin).
• Itching or rash at the injection site.
• Bruising or soreness at the infusion site.

Rare but possible risks and complications

Though complications are rare, it’s important to be aware of potential risks:

• Allergic Reaction: Some patients may experience an allergic reaction to the iron infusion. Signs include swelling, shortness of breath, hives, or a rapid heart rate. This is why the infusion is given slowly, and you are monitored closely during the procedure.
• Low Blood Pressure: A sudden drop in blood pressure can occur, causing dizziness or faintness.
• Iron Overload: This can occur if the body receives too much iron, though it’s rare and typically occurs with multiple infusions.
• Infection: There is a small risk of infection at the IV site.

After the infusion

• You may feel tired or lightheaded afterward, so it’s best to rest for the remainder of the day.
• Continue to drink plenty of water to help your body process the iron.
• Bruising or mild discomfort at the IV site is normal and should resolve within a few days.
