8-Chlorotheophylline, also known as 1,3-dimethyl-8-chloroxanthine, is a stimulant drug of the xanthine chemical class, with physiological effects similar to caffeine.[1] Its main use is in combination (salt) with diphenhydramine in the antiemetic dimenhydrinate. Diphenhydramine reduces nausea but causes drowsiness, and the stimulant properties of 8-Chlorotheophylline help reduce that side-effect.

Despite being classified as a xanthine stimulant, 8-Chlorotheophylline can generally not produce any locomotor activity above control in mice and does not appear to cross the blood-brain barrier well.
