How Can Hemolytic Anemia Be Prevented?

You can't prevent inherited types of hemolytic anemia. One exception is glucose-6-phosphate dehydrogenase (G6PD) deficiency.

If you're born with G6PD deficiency, you can avoid substances that may trigger the condition. For example, avoid fava beans, naphthalene (a substance found in some moth balls), and certain medicines (as your doctor advises).

Some types of acquired hemolytic anemia can be prevented. For example, reactions to blood transfusions, which can cause hemolytic anemia, can be prevented. This requires careful matching of blood types between the blood donor and the recipient.

Prompt and proper prenatal care can help you avoid the problems of Rh incompatibility. This condition can occur during pregnancy if a woman has Rh-negative blood and her baby has Rh-positive blood. "Rh-negative" and "Rh-positive" refer to whether your blood has Rh factor. Rh factor is a protein on red blood cells.

Rh incompatibility can lead to hemolytic anemia in a fetus or newborn.
