Medication for Fear of Flying

After very careful consideration Broadway Surgery have reviewed our benzodiazepine prescribing and established out new policy not to prescribe benzodiazepines or sedatives (such as diazepam) to patients for fear of flying. Many other GP practices have a similar policy. 

People often come to us requesting that we prescribe diazepam for fear of flying or to assist with sleep during flights. 

Initially in the 1960s benzodiazepines including Diazepam (also known as ‘Valium’) were hailed as a wonder drug. However, it became increasingly clear that, as well as having short term deleterious effects on memory, co-ordination, concentration, and reaction times, they were also addictive, with withdrawal leading to fits, hallucinations, agitation, and confusion. Furthermore, they were found to have long term effects on cognition and balance. Unfortunately, benzodiazepines have also become a widely used drug of abuse since they first came on the market. Because of these reasons the use of benzodiazepines has been a lot more controlled around the world since the 1980s-90s; especially in the UK. 

Diazepam in the UK is a Class C/ Schedule IV controlled drug. 

The following short guide outlines the issues surrounding its use with regards to flying and why our practice no longer prescribes such medications for this purpose. 

There are several very good reasons why prescribing this drug is not recommended. 

  • The use of any sort of benzodiazepines causes longer reaction times & as slowed thinking, which during a flight will put the passenger at significant risk of not being able to act in a manner which could save their life, or that of a loved one or co-passenger, in the event of a safety critical incident. Incapacitation from benzodiazepines is a risk to the lives of all on board the aircraft in the event of an emergency requiring evacuation. 
  • The use of such sedative drugs can make you fall asleep, however when you do sleep it is an unnatural non-REM sleep. This means you won’t move around as much as during natural sleep; this can cause you to be at an increased risk of developing a blood cot (Deep Vein Thrombosis- DVT) in the leg or even in the lungs. Blood clots are every dangerous and can even prove fatal. This risk is even greater if your flight is greater than 4 hours. 
  • Whilst most people find benzodiazepines like diazepam sedating, a small number have a paradoxical agitation and in aggression. They can also cause disinhibition and lead you to behave in a way that you would not normally. This could impact on your safety as well as that of other passengers and could also get you into trouble in law. 
  • Benzodiazepine use added to alcohol consumption causes an increase in the risk posed by the points above. 
  • According to prescribing guidelines doctors follow (British National Formulary) diazepam is contraindicated (not allowed) in treating phobic states. It also states that the use of benzodiazepines to treat short-term ‘mild’ anxiety is inappropriate. Your doctor would be taking a significant legal risk by prescribing against these guidelines. (They are only licensed short term for a crisis in generalised anxiety. If this is the case, you should be getting proper care and support for your mental health and not going on a flight; benzodiazepine doses used for flying previously are not likely control an acute crisis in generalised anxiety disorder). 
  • NICE guidelines suggest that medication should not be used for mild and self- limiting mental health disorders. In more significant anxiety related states, benzodiazepines, sedating antihistamines, or antipsychotics should not be prescribed. 
  • In some countries it is illegal to import these drugs, e.g., in the Middle East, and so the passenger will need to use a different strategy for the homeward bound journey and / or any subsequent legs of journey; they may be confiscated, or you may find yourself in trouble with the police. The passenger may also need to use a different strategy for the homeward bound journey and/ or other legs of the journey. 
  • Diazepam stays in your system for quite a while. If your job requires you to submit to random drug testing, you may fail this having taken diazepam. 
  • Benzodiazepines have been linked to the onset of dementia. 
  • A study published in 1997 from the Stanford University School of Medicine (iv) showed that there is evidence use of benzodiazepines stops the normal adjustment response that would gradually lessen anxiety over tune and therefore perpetuates and may increase anxiety in the long term, especially if used repeatedly. In an article in Clinical Psychiatry News, Shanna Treworgy. Psy.D of the Dartmouth Geisel Medical School, said that though there may be reduced anxiety in the moment, benzodiazepines caused increased long-term anxiety reactions.

 

Given the above we will no longer be providing Diazepam for flight anxiety and instead suggest the below aviation industry recommended flight anxiety courses which are easily accessible for those who wish to fly & conquer their fear of flying, e.g.

  • Flight anxiety does not come under the remit of General Medical Services as defined in the GP contract and so we are not obliged to prescribe for this.
  • Patients who still wish to take benzodiazepines for flight anxiety are advised to consult with a private GP or travel clinic.
  • It is important to declare all medical conditions and medications you take to your travel insurer. If not, there is a risk of nullifying any insurance policy you may have.
