The half-life of elimination of propofol has been estimated to be between 2 and 24 hours. However, its duration of clinical effect is much shorter, because propofol is rapidly distributed into peripheral tissues.

When administered intravenously, propofol is rapidly cleared from the circulation . Its clearance takes place by redistribution possibly into the lungs and more importantly in the liver. Only 0.3% of the dose is excreted, unchanged, in the urine. The elimination half-life of propofol is approximately 0.5 h to 1.5 h.
How long does it take for propofol to wear off after colonoscopy?

What are the long term side effects of propofol?
Conclusion: The limited data available suggest that long-term infusion of propofol is a practical alternative to use of standard agents for sedation of intubated patients. Adverse effects such as cardiovascular depression, respiratory depression, and hypertriglyceridemia may limit the routine use of propofol.
How is propofol eliminated from the body?
Elimination. Propofol is mainly eliminated (73% of the dose in 24 h and 88% in 120 h) by glomerular filtration (renal clearance of 120 ml/min) as water-soluble metabolites and/or bile [108, 109].

Patients do not talk during the anaesthetic while they are unconscious , but it is not uncommon for them to do so during emergence from anaesthesia.

What is the 1 2 life of propofol?
Half-life: Propofol is bi-phasic, with its initial half-life being relatively quick, around 40 minutes, and its terminal half-life usually being 4 to 7 hours . Context-sensitive half-time may be up to 1 to 3 days after a 10-day infusion. The clinical effect of propofol is much shorter in duration.
