Three diabetic cases of acute dizziness due to initial administration of voglibose

Abstract

We observed 3 diabetic patients with intolerable dizziness followed by nausea and vomiting immediately after an initial administration of the alpha- glucosidase inhibitor, voglibose. These symptoms did not recur after discontinuation of the drug. Adverse effects as observed in these cases have not been reported previously. Since the 3 patients were relatively old (average age, 72 years old) and had various degrees of micro- and macroangiopathies, these side effects may have been associated with increased micro- and macrocirculatory disturbances in their central nervous systems through alpha-glucosidase inhibition of this agent.
