Patients with sickle cell disease (SCD) require comprehensive care to manage the symptoms and complications of their disease. In addition to
managing your disease with actions to remain healthy and pain management, there may be times where more treatment is necessary. Show Blood TransfusionSome sickle cell patients need blood transfusions (simple or exchange) because of severe anemia, before surgery or to help control pain. Emergency blood transfusion is used to treat stroke and acute chest syndrome. Patients who have had a stroke may receive chronic transfusion therapy (blood transfusions every 4 to 6 weeks) to prevent a second stroke and other SCD complications. Blood transfusions have potential complications including too much iron over time or transfusion reactions like hives and other symptoms of an allergic response. A person’s immune system can also develop antibodies that can make finding matching blood difficult. Blood transfusions also carry a very low risk for infections such as HIV and hepatitis. Any possible complications are checked closely and will be addressed as needed. If your provider suggests a blood transfusion, you will need blood drawn. You will also need to sign a consent. In the outpatient setting, a new consent is needed each year. Transfusions are given in the Infusion Clinic on the first floor of the Specialty Clinics building at Froedtert Hospital. Hydroxyurea to Treat Sickle Cell DiseaseHydroxyurea (Hydrea) is the only approved medication to treat sickle cell disease. The medication works by several mechanisms, but primarily by increasing the fetal hemoglobin in your blood which in turn results in less sickle cell hemoglobin. Studies have shown having fewer sickle cells can help decrease pain, and patients who take hydroxyurea live longer.
Additional Medications to Treat Sickle Cell Disease SymptomsThe following is a list of common medications that are used to help treat and manage SCD and its symptoms.
Supporting CareSickle cell disease can affect many organ systems. Therefore, it can cause a variety of symptoms and complications. Many times, a patient will need different types of therapies to treat these symptoms and complications. Sometimes, a patient will need to work with other medical specialists. HydroxyureaHydroxyurea is a once-daily medication which may decrease the chances of acute pain events and hospitalizations and may prevent organ damage in adults and children with sickle cell disease. It also helps decrease the amount of anemia a patient experiences. Consistent use of hydroxyurea provides a protective effect by increasing the amount of fetal hemoglobin (Hemoglobin F) contained in red blood cells. Cells with more Hemoglobin F are less likely to sickle. Side effects of hydroxyurea, although rare, may include nausea, gastrointestinal irritation, and headache. Contact your physician immediately if side effects occur. Hydroxyurea therapy requires regular laboratory monitoring for problems. Neutropenia (low white blood count), thrombocytopenia (low platelet count), or decreased reticulocyte count (without an associated increase in hemoglobin) may mean the dose is too high. If this happens, the daily dose may be reduced or stopped for a period to allow your blood counts to recover. Once this occurs, medication may be restarted at the same or a lower dose. EndariTMWhat is L-glutamine (EndariTM)?In July 2017, L-glutamine was approved by the FDA for people with sickle cell disease (SCD) ages 5 years and older.
How do you take L-glutamine?L-glutamine is a powder. It must be mixed well in 8 ounces of a cold beverage, yogurt, or applesauce. It is taken twice a day and the number of packets depends on your weight:
How can L-glutamine benefit sickle cell patients?A study carried out in 31 centers in the United States led to FDA approval. Patients on the study could continue taking hydroxyurea. (Niihara Y, et al. A Phase 3 Trial of L-Glutamine in Sickle Cell Disease. N Engl J Med 2018; 379:226-235)

What is the new treatment for sickle cell anemia?Crizanlizumab takes a different approach in supporting circulation. Instead of focusing on improving hemoglobin in red blood cells, this therapy aims to make blood vessel walls less sticky, which helps prevent sickled cells from clotting together and altering blood flow.
What is the best blood tonic for sickle cell patient?Hydroxyurea. The drug hydroxyurea is approved for use in adults with sickle cell anemia, and is sometimes used in children too. Hydroxyurea causes the body to produce fetal hemoglobin, a type of hemoglobin that is normally produced only before and shortly after birth.
What should sickle cell patients avoid?avoid very strenuous exercise – people with sickle cell disease should be active, but intense activities that cause you to become seriously out of breath are best avoided. avoid alcohol and smoking – alcohol can cause you to become dehydrated and smoking can trigger a serious lung condition called acute chest syndrome.
