What is Sickle Cell Disease?

Sickle Cell Anemia (SCA) is one of a group of inherited disorders known as sickle cell disease (SCD).

Sickle cell disease affects red blood cells.

Normal red blood cells are round and flexible and can move easily through blood vessels.

For people with SCD, their red blood cells become stiff and curved (or shaped like a “sickle”), causing these cells to stick to blood vessels and block blood flow.

The blockages can cause crippling pain and other complications that can lead to hospitalization.

Your healthcare provider may change your dose or tell you to stop taking SIKLOS if you have low blood cell counts. Tell your healthcare provider right away if you get any of the following symptoms: fever or chills; shortness of breath; body aches; unusual headache; feeling very tired; bleeding or unexplained bruising.
