title: Hematological side effects from antihypertensive drugs.
abstract: To sum up, some hematological side effects are seen after antihypertensive drugs. They are, however, few, usually not severe and furthermore reversible. And so, from the viewpoint of the hematologist, there are no contraindications against antihypertensive treatment. The prevalence of side effects on blood and blood-forming organs from antihypertensive drugs is low. Of certain interest are 1) the tendency of modern diuretics (thiazides) to cause a moderate and reversible thrombocytopenia and 2) the positive antiglobulin reaction (Coomb's test) sometimes seen after alpha-methyldopa therapy and in a few cases causing autoimmune hemolytic anemia. Even though case reports have appeared on leukopenia/agranulocytosis related to almost all drugs used in the treatment of hypertension, none of these drugs seem to be especially prone to cause any damage to leukocytes and/or leukocyte production.
