Question to the Ministry of Defence:

To ask the Secretary of State for Defence, which (a) medicinal and (b) non-medicinal products have been approved for use by armed forces service personnel to aid them in staying alert.

In the Defence Primary Healthcare Formulary and operational medical modules (the equipment and materiel component of deployed medical operational capability) there are currently no approved medicinal products for use by Service personnel to aid them in staying alert.

Regarding non-medicinal products, there is Defence policy about the use of caffeine as a stimulant in aircrew. There is also policy stipulating that all personnel involved in flying duties should only be prescribed medication or remedies by a Military Aviation Medical Expert.
