1. What is therapeutic phlebotomy?

• Definition: Therapeutic phlebotomy is a medically ordered blood removal procedure used to lower excess iron or reduce high red blood cell levels.

• Common reasons:

• Hemochromatosis (too much iron)

• Polycythemia vera or other conditions with thick or over‑concentrated blood

• Other disorders where your doctor wants to reduce blood volume or iron stores

• It is similar to donating blood, but it is done specifically as part of your treatment plan.

• ​

• 2. What is it for?

• Lowering iron: Helps prevent iron from building up in organs like the liver, heart, and pancreas.

• Reducing blood thickness: Helps improve circulation and reduce strain on the heart and blood vessels.

• Supporting your treatment plan: Your doctor uses lab results and your diagnosis to decide how often and how much blood should be removed.

• 
  3. How to request therapeutic phlebotomy

• Talk to your physician or specialist

• Ask if therapeutic phlebotomy is part of your treatment plan.

• Get a written order

• Your doctor must provide therapeutic phlebotomy orders that include:

• Diagnosis (reason for phlebotomy)

• Frequency (how often: weekly, monthly, etc.)

• Amount to remove (for example: 250–500 mL)

• Target lab values (such as hemoglobin, hematocrit, ferritin goals)

• Get current lab work done

• Your doctor may order labs such as:

• CBC (Complete Blood Count)

• CMP (Comprehensive Metabolic Panel)

• Iron studies / ferritin

• These help confirm it is safe to perform the procedure.

• 
  4. What you need to bring to your appointment

• Before your therapeutic phlebotomy visit, make sure you have:

• Doctor’s orders for therapeutic phlebotomy

• Including frequency and amount of blood to remove

• Recent lab results (if available)

• CBC

• CMP

• Iron studies / ferritin or other labs your doctor ordered

• Photo ID

• Insurance information (if required by your provider or clinic)

• If your doctor’s office is sending orders directly, confirm they have been faxed or emailed before your appointment.

• 
  5. What happens during the appointment

• Check‑in and review

• Your identity is confirmed.

• Your therapeutic phlebotomy orders and recent labs are reviewed.

• The clinician explains the procedure and answers questions.

• Positioning and preparation

• You will sit or lie down in a comfortable position.

• A blood pressure cuff or tourniquet may be used to help find a vein.

• The skin is cleaned with antiseptic.

• Blood removal

• A sterile needle is placed into a vein in your arm.

• Blood flows into a collection bag or container.

• The amount removed is based on your doctor’s order (for example, 250–500 mL).

• Monitoring

• Your symptoms are monitored during the procedure.

• If you feel lightheaded, nauseated, or weak, the clinician can slow or stop the procedure.

• After the procedure

• The needle is removed and a bandage is applied.

• You may rest for a short time while your blood pressure and symptoms are checked.

• You receive instructions about fluids, food, and activity for the rest of the day.

• 
  6. Why eating and drinking before your appointment is important

• Therapeutic phlebotomy removes a noticeable amount of blood from your body. If you arrive under‑fed or under‑hydrated, you are more likely to feel:

• Weak

• Dizzy or lightheaded

• Nauseated

• Faint

• To reduce these risks:

• Eat a full meal 1–2 hours before your appointment

• Include protein (eggs, meat, beans, yogurt) and complex carbohydrates (whole grains, vegetables).

• Drink plenty of fluids

• Aim for at least 24 oz of water before your appointment.

• Your doctor may also recommend electrolytes (such as sports drinks or electrolyte solutions).

• Avoid coming in fasting unless your doctor specifically instructs you to fast for other labs.

• Arriving well‑nourished and hydrated helps your body tolerate the blood removal and lowers the chance of dizziness or fainting.

• 
  7. After‑care: what to do after your session

• Continue hydrating for the rest of the day.

• Eat a balanced meal to support recovery.

• Avoid heavy exercise or strenuous activity until you feel fully back to normal.

• Stand up slowly from sitting or lying positions to prevent lightheadedness.

• Follow your doctor’s instructions about follow‑up labs and future phlebotomy sessions.
