Q

Propofol patient educations ?

A

Propofol can cause severe drowsiness or dizziness, which may last for several hours. You will need someone to drive you home after your surgery or procedure.

Do not drive yourself or do anything that requires you to be awake and alert for at least 24 hours after you have been treated with propofol.
