You cannot send meds by mail/courier without getting past through customs. Also, all medicines are checked/screened by the medical commission and you need to present your prescription to them for release. They will open each and every packet, and literraly count the meds in front of you. Bottomline, it is a very rigorous process. It would be better if you bring in your meds that will last until your next rotation, that's probably 3 months if you are from the US. Just don't stress yourself too much so that you won't get any breakout...

Good luck...
