Abstract Atomic force microscopy (AFM), a powerful characterization tool widely applied in problems in a large range of disciplines of the natural sciences, including cellular biology, was used to obtain information about the morphological changes induced in the erythrocyte membrane at the patients with epilepsy that undergo a long time treatment that operates upon one or several neuronal ionic channels, comparative with a healthy donor. This technique allowed non‐invasive imaging of erythrocyte membrane, revealing details and specific characteristics down to the nanometer level with characterization of surface texture parameters, such as average height, average roughness and coefficient of kurtosis at micrometer/nanometer resolution. For the healthy donor the AFM morphology appears to have all the characteristics of a normal red blood cell membrane. Instead, the closer examination of the erythrocytes membrane surface morphology for the samples collected from the patients diagnosed with epilepsy and treated with specific drugs did not reveal similar structures with those obtained for the healthy donor. The nanostructure of the membrane was drastically damaged, depending on the administrated treatment, and probably in time will affect their functionality. Therefore, the anticomital drugs have influence not only at the neuronal level, but also at the red blood cell level.
