TCCC working group discussed it. They ran into problems with choosing the right type. I appologize, I am not up to date on the specific drugs. The US changes the type frequently. The broad spectrum one they were using at the time the WG discussed had a confliction issue with Mefloquin. There is no doubt that there are effective braod spectrum ones out there that dont conflict with other drugs, and have a low allergy frequency. The US is probably using them right now. I think the current problem is that there just isn't the staff or time to research, recommend and impliment this. This is just the CF's priority due to poverty. It's unfortunate. Everyone in the US Army gets a pill pack in theatre. When you get shot or blowed up, and you're still conscious, you pop your pill pack full of pain relief anti-inflamitories and a dose of anti-biotics that will do you for 24hrs (prophylactically as was mentioned). Maybe one day, after we sort out the tourniquet and HSD issue we can move onto this, and try mitigate that 12%ish that DOW.
