Chloroquine Genetic Information
G6PD is an enzyme in your body that is responsible for helping red blood cells to work properly. Some patients are born with less of this enzyme in their bodies, leading to the destruction of red blood cells. Chloroquine can also lead to the destruction of red blood cells. When chloroquine is used in patients with G6PD deficiency, they have a higher chance of experiencing hemolytic anemia (a condition in which the body does not have enough red blood cells to deliver oxygen to your tissues).
G6PD testing may be done to determine whether you are at a higher risk of experiencing hemolytic anemia if you are to be treated with chloroquine.
If you need the medication chloroquine and you have a deficiency of G6PD, your doctor will monitor you carefully.
