Fear of Flying

Why We Do Not Prescribe Diazepam for Flying

Medical Guidelines and Licensing

Diazepam is a Class C/Schedule IV controlled drug in the UK. According to the British National Formulary (BNF), benzodiazepines are not recommended for treating phobias or mild anxiety, and are only licensed for short-term crisis management in generalised anxiety disorder. Fear of flying alone does not fall under this category, and prescribing diazepam in such cases would be against medical guidance.

Safety Risks During a Flight

While diazepam can cause sedation, it also reduces awareness and reaction times, which could be dangerous in an emergency. In the event of an evacuation, you may not be able to react quickly enough to protect yourself or others.

Increased Risk of Blood Clots (DVT)

Sedative medications like diazepam reduce natural movement during sleep, increasing the risk of developing deep vein thrombosis (DVT). This risk is especially significant on flights over four hours.

Unpredictable Side Effects

While most people experience sedation, a small number may develop paradoxical agitation, aggression, or disinhibition, which could lead to disruptive or unsafe behaviour onboard. These effects are similar to excessive alcohol consumption and could result in removal from a flight or legal consequences.

Legal and Travel Considerations

Diazepam is a controlled drug and illegal in several countries. Carrying it without proper authorisation could lead to confiscation or legal issues abroad. Additionally, failing to disclose its use to your travel insurer could invalidate your policy.
