You will need to remain in the facility for at least 3 hours after you receive the medication. While you are in the clinic, the medical staff will watch you closely for signs of PDSS. When you are ready to leave the facility, you will need a responsible person to be with you, and you should not drive a car or operate machinery for the rest of the day. Get emergency medical help right away if you experience any symptoms of PDSS after you leave the facility.
