The anti-malarial Larium (mefloquine) has been described as the worst form of friendly fire by the wife of a major-general after he endured crippling mental health problems since taking the drug.
Ellen Duncan says her husband Major-General Alastair Duncan suffered post-traumatic stress disorder (PTSD) after he was given the drug, and he has since been sectioned under the Mental Health Act.
In an interview with the BBC, Mrs Duncan said: There is an institutional denial at the Ministry of Defence about how bad the effects can be. It`s the worst form of friendly fire.
Nearly a thousand British military personnel have been treated for mental health issues after taking Lariam, according to the Ministry of Defence.
The drug has known side effects of depression and anxiety, and a UK House of Commons committee is investigating its safety.
