Etymology

The word diphenhydramine comes from how chemists name molecules: diphen- means 'two ring parts' and -amine means 'a nitrogen group'. A helpful way to remember it is that the name simply describes the drug's chemical parts, which is why diphenhydramine is the long name for the common allergy medicine Benadryl.
