“… the response [from Ministry of Defence officials] was a mixture of incomprehension, indifference and sometimes hostility.”

During the inquiry the Committee heard evidence from Ministry of Defence (MoD) officials, Roche executives, medical experts and mefloquine veterans. These included Dr Ashley Croft, who described his efforts at raising concerns over mefloquine safety to senior MoD officials for many years:

Dr Croft: I agree with my colleague, Dr Nevin. The guidelines can be summarised in one sentence, which is that mefloquine is the least safe of the available anti-malarial regimens currently used, and the Roche representatives came out with that statement when they gave evidence here four weeks ago. Whether that statement is in the guidelines, I do not know. I think that the guidelines give a lot of information about side effects, but do they actually spell it out as simply as that, that this is the least safe drug you can take to prevent malaria?

Q95   Chair: How widely recognised would you say that statement is?

Dr Croft: It is documented from a randomised control trial carried out in international travellers and reported in 2001—the Overbosch study. It was a very late study because the drug had already been used on travellers for more than 20 years, and the study proved without doubt that mefloquine is the least safe of the drugs, and causes neuro-psychiatric effects in travellers at a greater level than equivalent medication—in that case they were comparing it to Malarone.

Q96   Chair: You were professionally in the military in this capacity, so is this a point that you ever raised with the Ministry of Defence?

Dr Croft: I raised it constantly, and the response was a mixture of incomprehension, indifference and sometimes hostility.

Q97   Chair: Why do you think there is that determination or, if you like, denial of what you say is a widely recognised assessment of the risks of the drug?

Dr Croft: As you said yourself, Mr Chairman, four weeks ago, this position seems to be contrary to reason. It is not a position than anyone in a reasonable world would take, to be giving soldiers the least safe drug to prevent malaria. So that is a question you would have to put to those who have adopted this illogical and irrational position. read more
