Patient Information: Why We Do Not Prescribe Diazepam for MRI Scans, Dental Work, or Similar Procedures

We understand that having an MRI scan, dental treatment, or another medical procedure can feel worrying. However, we cannot prescribe diazepam (a sedative) for these situations. Below we explain why, and what other options may be available.

 

Reasons We Do Not Prescribe Diazepam

Safety concerns

  • Diazepam makes you very drowsy and can slow your breathing. Some people have the opposite effect and become agitated.

Timing problems

  • Appointments often run late. If you take diazepam too early or too late, it may wear off at the wrong time or be too strong.
  • Your appointment may be cancelled at the last minute, meaning you would have taken unnecessary medication.

Specialist responsibility

  • If sedation is needed, it should be arranged by the hospital, dentist, or clinic. They can give the right medicine and monitor you safely.

Side effects and risks

  • Diazepam can leave you groggy, confused, or unsteady. It can affect memory, driving, and work. It can also cause dependence if used repeatedly.

Prescribing rules

  • National guidelines (BNF) say diazepam should not be used for phobias (such as claustrophobia) or mild short-term anxiety about procedures.

What You Can Do Instead

  • Talk to your hospital or dentist – They may be able to arrange sedation in a safe setting, offer breaks, or use different equipment (like an open MRI).
  • Practical tips – Listening to music, breathing exercises, or having a trusted person with you can help.
  • Specialist support – If anxiety is an ongoing problem, your GP can discuss counselling, CBT (talking therapy), or referral for further support.

Summary

We know that medical procedures can feel overwhelming. Diazepam is not a safe or suitable option for these situations when prescribed in advance. Please speak to your hospital team or dentist about your worries so they can make the right arrangements to keep you safe and supported.
