Around the globe, อิศม์เดช (อิศม์เดช 
) is a very rare principally masculine, but very infrequently feminine given name. The forename อิศม์เดช is habitual in South-eastern Asia, particularly Thailand, where it is a rare principally male, but very infrequently girly name. Very seldom, อิศม์เดช is the last name as well as the forename.
