Tag: Drug induced macrocytosis

Medication-induced macrocytosis is the most common cause of elevated mean corpuscular volume (MCV) in non-alcoholic patients. This means many everyday drugs can lead to an increase in red blood cell size, even without causing anemia. Identifying *what drugs cause high MCV* is crucial for accurate diagnosis and patient management.

In some studies, drug-induced macrocytosis is the third most common cause of an elevated Mean Corpuscular Volume (MCV), accounting for about 12.9% of cases [1.11.1]. Understanding **what drugs cause high MCV** is crucial for clinicians to differentiate medication side effects from other serious conditions.
