Question to the Ministry of Defence:

To ask Her Majesty’s Government whether Lariam (mefloquine) is administered to pilots and air crew serving in the armed forces.

As with all prescriptions the Ministry of Defence follows the drug manufacturer's advice which stipulates that Mefloquine (commercially known as Lariam) should not be taken if you are carrying out complex tasks such as driving, piloting an aircraft or diving. Accordingly, the Department's current policy is that aircrew are not to take Mefloquine.
