I have find this thread so incredibly judgmental, with very patronising posts and so many wrong misconceptions.
People who as for a few valium to help them fly are NOT addicts if this is the sole purpose of taking it. The risk of addiction are much stronger with people taking codeine over time which is available over the counter.
Valium is very chesp: 76p for 28 2mg tablets. The NHS is making money out of those people who pay for their prescription.
Guidance and guidelines are just that, they are not set in law. Only NICE Technical Appraisal Guidelines are. These relate more about what the NHS should prescribe rather than shouldn't.
GP can prescribe unlicensed drugs, but they need to feel comfortable with their decision to do so. Interesting none of those supposed GPs posting on this thread as commented on my analogy of melatonin prescribing to children.
Ironically, Ipswich and Norfolk CCG guidance (as an example) on the prescription of valium a tuslly indicate that it should be prescribed only for occasional events, specifying flying as an example.
Of course no one has to fly. Then again, no one has to have penetrative sex either yet Viagra is available on the NHS. For some,being able to fly is key to their relationship. I used to work with a colleague who refused to fly. She met a new partner in her 50s, they retired 5 years later. He was desperate to go and travel the world in retirement, she knew it and had promise to sort out her fear of flying. She couldn't do it and in the end, this build such conflict in their relationship, they decided to separate.
As said, those desperate to fly who will only do so with valium will find a way around it to still get it, so the main reason to recommand not prescribe any longer will change very little, planes will still fly with people on valium, or sleeping pills, or large amount of alcohol in their bodies, probably causing more problems then a regulated small prescription.
