Hematologic

Drugs that build and support the blood — treating anemia and boosting red- and white-cell production. Four classes spanning the raw materials (iron, B12, folate) and the growth-factor signals (erythropoietin, G-CSF) of hematopoiesis.

4 drug classes 11 key drugs

Iron / Anemia Agents

High-yield

Replace iron for iron-deficiency anemia. Dark stools & constipation are expected; IV iron risks reactions.

Vitamin B12 & Folate

High-yield

Replace the vitamins for megaloblastic anemia. Folate must never mask B12 deficiency (neuro damage continues).

Erythropoiesis-Stimulating Agents (ESAs)

epoetin High-yield

Boost red-cell production in CKD/chemo anemia. Boxed warning: thrombosis — do not over-correct hemoglobin.

Colony-Stimulating Factors

filgrastim

Boost neutrophils after chemo to prevent infection. Bone pain is common; watch for rare splenic rupture.
