Leukopenia can lead to serious infection and death if the condition is not treated early, according to News Medical. Leukopenia is a blood condition wherein the patient's marrow does not produce enough white blood cells, or leukocytes, explains Antimicrobe.
Leukopenia often appears as a complication resulting from an earlier illness, according to News Medical. When this is the case, the leukopenia is treated by targeting its precursor. Health conditions that can lead to leukopenia include thyroid disorders, aplastic anemia and deficiencies in vitamins. A patient might experience leukopenia as a side effect of chemotherapy or radiation therapy. Tuberculosis, malaria and Rickettsial infections can cause leukopenia. In some cases, low leukocyte counts stem from genetic deficiencies.
Individual drugs that can cause leukopenia include sirolimus, clozapine, cyclosporine and lamotrigine, according to News Medical. Leukopenia is identified by conducting a blood count. White blood cell levels are dangerously low if they are measured at less than 1000 cells per microliter. Neutropenia is the most common type of leukopenia and is characterized by low counts of neutrophils. These are the white blood cells responsible for counteracting bacteria, fungi, viruses and parasites. Though some take echinacea to treat leukopenia naturally, its effectiveness is unproven, says WebMD.
