It's certainly a good idea to encourage different medications over mefloquine. All of the quinine-based drugs carry at least some risk. Mefloquine's risk, from what I gather, seems to be unique, but none of them are entirely without some risk. I would be concerned about people requesting mefloquine specifically and I'd be curious as to know why. Are people getting the informed consent they need to make a decision about whether or not mefloquine should be the drug of choice here? What's behind someone saying, “I'd like to take mefloquine”? Based on what I know about it, it seems to be a fairly surprising choice.
