Question to the Ministry of Defence:

To ask the Secretary of State for Defence, how many claims have been made by current or former service personnel in respect of adverse effects caused by being prescribed the drug mefloquine, larium, in each of the last three years for which information is available; and of those, how many have been resolved.

The Department has been notified of a total of 686 common law claims relating to the alleged adverse effects of Lariam. A breakdown of claims in each of the last three years is not readily available, however, most the claims were notified prior to April 2021. The Ministry of Defence continues to resolve claims wherever possible.
