Prescriptions for Flight/Travel

Please note that we do not prescribe medication for patients who suffer anxiety when flying. Even if you have been given medication previously this is not something we now provide.

Please refer to your flight carrier website who provide advice for patients who are nervous or who have a fear of flying

Flying Phobia or Anxiety Prescriptions

We are often asked to prescribe sedative drugs, such as diazepam (Valium), for anxiety when flying. We no longer prescribe these drugs for flying. There are a number of good reasons why prescribing of drugs such as diazepam is not safe or recommended:-

Diazepam and similar drugs are not recommended for treatment of phobias because other treatments are safer and more effective.

Diazepam is a sedative, which means it makes you sleepy and slows reaction times. If there is an emergency during the flight it may affect your ability to concentrate, follow instructions and react to the situation. This could have serious safety consequences for you and others.

The sedative effects of these drugs can affect breathing and cause low oxygen levels, which could be life threatening, especially with the lower circulating oxygen levels on an aeroplane, in people with breathing problems or when combined with alcohol.

Sedative drugs can make you fall asleep, however this is not a natural sleep. This means you won’t move around as much as during natural sleep and this can increase your risk of developing a blood clot (DVT) in your leg or lung. Blood clots are dangerous and can be fatal. This risk is greater if your flight is longer than four hours.

Whilst most people find medicines such as diazepam sedating, a small number of people become agitated, aggressive or confused. These medicines can also cause disinhibition and lead to abnormal behaviours. This could impact on your safety as well as that of other passengers.

Diazepam and similar drugs are illegal or controlled drugs in some countries so they may be confiscated or you may be subject to legal proceedings.

Diazepam stays in your system for quite a while. If your job requires you to submit to random drug testing you may fail this test if you have taken diazepam.

We recognise that fear of flying is real and frightening and we don’t underestimate the impact it can have. We recommend tackling this properly by using self-help resources or considering one of the ‘Fear of Flying’ course run by many airlines. We do not recommend any specific course but you may find the following links useful.

Jet Lag Prescriptions

We are sometimes asked to prescribe sedative drugs, such as Zopiclone, or Melatonin for jet lag. There are a number of good reasons why prescribing of drugs such as Zopiclone or Melatonin is not safe or recommended:-

Medicines are not usually needed for jet lag.

Jet lag often improves after a few days as your body clock adjusts to the new time zone.

There are things that you can do to help – see the website for more information: Jet lag – NHS (

Sleeping tablets may be helpful if you’re having problems sleeping (insomnia). But they can be addictive so should only be used for a short time and if symptoms are severe. As Jet Lag will resolve on its own this does not meet the threshold for prescribing these tablets.

Melatonin is a natural hormone released by the body in the evening to let your brain know it’s time to sleep.

Melatonin tablets are not recommended for jet lag because there’s not enough evidence to show they work.
