One of the most common questions we hear from anxious patients isn't "is it safe?", it's "what will it actually feel like?" Not knowing what to expect is often the hardest part of anxiety, so here's an honest, step-by-step walkthrough of the experience.
The first step is a pre-assessment to determine whether it’s safe to sedate you in primary care. This is undertaken either during your consultation or at a separate appointment on a day before your treatment appointment. At the pre-assessment you’ll be given clear instructions verbally and in writing. These typically including fasting guidelines (usually a light breakfast or lunch) and arranging a responsible adult to escort you home afterwards. Wearing loose, comfortable clothing on the day, particularly something that allows easy access to your arm, makes things easier.
You'll be greeted by our team and given time to ask any last questions before treatment begins. There's no rush, if you need a few extra minutes to settle your nerves, that's completely normal and expected. We will re-take your blood pressure and oxygen levels and ask you to re-sign the consent form you signed during your pre-assessment.
A small cannula (a thin, flexible tube) is placed into a vein, usually in the back of your hand or your arm. Most patients describe this as feeling similar to a standard blood test - a brief pinch rather than significant pain.
Once the sedative is administered through the cannula, most patients describe a rapid sense of calm and relaxation, often within a minute or two. Common descriptions include:
You are not unconscious. You'll continue to breathe independently and can respond to instructions, such as being asked to turn your head, but many patients feel detached enough that the procedure passes without the anxiety they anticipated.
Local anaesthetic is still used alongside sedation to ensure the treatment area itself is completely numb. Your vital signs are monitored continuously throughout. Many patients later describe the procedure as feeling like it took a few minutes, even when it lasted considerably longer.
This is one of the most reassuring aspects of IV sedation for many patients: it's common to have little or no memory of the procedure itself, even though you were technically conscious throughout. Some patients recall fragments; others recall almost nothing between the sedative taking effect and waking up in recovery.
You'll be moved to a recovery area and monitored until you're ready to go home. You'll likely feel groggy, and this is completely normal, it's why an escort is essential. Most patients don't remember much of this immediate recovery period either.
Sedation effects continue for several hours, so the rest of the day is typically spent resting at home. You won't be able to drive, operate machinery, sign important documents, or make significant decisions until the following day, as your judgement and coordination remain affected for longer than you might expect.
Most patients feel back to normal by the next morning, but it’s important you don’t drive for the full 24 hours. The surgical site itself following its own separate healing timeline, which we'll cover in your specific aftercare instructions.
That's completely understandable, and exactly why we take time during your consultation and pre-assessment to talk through the process in detail, answer every question, and make sure you feel as prepared and reassured as possible before your appointment.
