The former Celtic striker regained conciousness on the field and walked to the vehicle pitchside and eventually left the stadium at the wheel of his own car.
Spanish press reported Dembele had a drop in blood pressure but is doing well.
Dembele joined Atleti on loan from Lyon in January and is yet to score in two appearances.
