Figures show nearly 1,000 have sought psychiatric treatment after being given the MoD’s budget price anti-malarial drug Lariam.
A Freedom of Information (FoI) request revealed the figure is much higher than previously thought, with 994 service personnel being admitted to mental health clinics or psychiatric hospitals since 2008.
The figures only go back to 2007, so the true number may be much higher, as Lariam, also known as mefloquine, has been in use for much longer.
