Usually when a medication is prescribed that people are taking in theatre, members of the Canadian Armed Forces are advised that if they're having some concerns with any effects they may think are attributable to the drug, they should come forward and tell us about those so that we can help to understand whether or not those are related to the medication or some other confounding factor as a result of their deployment.
We don't specifically go and do a follow-up screening for those who have received mefloquine. It's not part of our process.
With respect to mental health, it depends on the size of our deployment. In Afghanistan, at our role 3 hospital, we had a psychiatrist, a social worker, and a mental health nurse right in the hospital available to assist anybody who might have some mental health symptoms.
But when we have smaller missions, we still often have physician assistants or physicians who are also capable of helping people with mental health issues, at least in the initial phases, and of making a decision as to whether or not they need to come for more advanced care.
