"The patient should be advised not to drive, make important decisions, or consume alcohol for a period of 24 hours after the appointment." Donaldson M 2007 p. 124
"On the day of the appointment, it would be prudent to administer the medication in the dental office where it is a controlled and monitored environment." Donaldson M 2007 p. 124
Helpful to see patient's baseline before starting medication because some patients will self-medicate increasing their risk for over dosage.
If inadequate sedation, do not give additional oral dose because it takes hours for peak effects so greater risk of over medicating. If need to titrate dose, then give additional medications by parenteral route for quicker, titratable effect but the depth of sedation is now deeper than minimal sedation.
