Sedation for CT and MRI Scans
Sedation for CT and MRI Scans
We do not prescribe sedative medication (such as diazepam) for patients having CT or MRI scans.
Patients sometimes ask for medication to help them feel calmer before a scan. We understand this, but it is not safe or appropriate for GP practices to prescribe sedatives for procedures carried out in hospital.
Why we do not prescribe sedatives
- GP practices are not able to monitor patients during or after sedation for hospital procedures
- Sedative medicines can be unpredictable:
- Low doses may not work well
- Some people may have unexpected or opposite reactions
- The timing may be wrong if appointments are delayed, making the medication less effective or unsafe
- Taking sedatives without proper monitoring can lead to serious health risks, including breathing problems
Safe use of sedation
Sedation should only be given by a trained and qualified hospital team who can:
- Assess the patient before the procedure
- Plan and give the correct medication
- Monitor the patient throughout
- Respond quickly in case of any problems
Hospitals and specialists can prescribe the same medicines as GPs and are best placed to do this safely.
What this means for you
If you are worried about having a scan:
- Please tell your GP when the scan is requested, or
- Contact the radiology department before your appointment
They can review your needs and arrange the right support, including sedation if it is appropriate.
Important information
To keep patients safe and ensure proper care, we will not prescribe sedatives for imaging procedures, even if requested by another service. If support is needed, this should be arranged by the hospital team.
