What is photopheresis?
Photopheresis is a medical procedure that can treat graft versus host disease. It involves suppressing the immune system to prevent it from reacting adversely on the skin.
What happens during the procedure?
A catheter is used to draw blood from the body and pass it through a special machine. The machine removes the lymphocytes from the blood, treats them and returns them to the blood. Then the blood is returned to the body through a catheter. The treatment lasts 3 to 4 hours and may require a few sessions to achieve the desired results.
Is any special preparation needed?
No special preparation is needed for photopheresis.
What are the risk factors?
Dizziness, lightheadedness, a tingling sensation, cramping or low blood pressure are potential side effects of photopheresis.
