I work as a remote
area paramedic/rescue paramedic. Medications are not as easy to give as a lot of people might think. Many have extreme side effects which can cause the situation to become much worse than the root cause. ie morphine can quite often stop you from breathing.
I have an extensive medical kit along with a license
I would sugest you focus on the first aid, CPR, Blood control, broken bone management and basic cleaning
of wounds etc.
An EPI-pen is good for 12 months, however, if you use adrenalin ampoules and a syringe, you can do more and last longer. Epi-pens are good for about 15 minutes anyway.
As Paramedics specialise in emergency
medicine and remote
area medicine, I would sugest you make a friend at your local ambulance depot and get some private training. I have done this for many people with a target on what adventure they are looking to undertake. I don't charge, so I am guessing, many others don't.
I have worked all over the world, I inspect the medications carefully in some third world countries. Many fakes and out of date meds with new labels. In India
, i found the medications from main pharmacies to be genuine items.(mind you, they did act differently once they know I was an informed buyer)
I would make sure you have your "shots" before you go, such as A.D.T. shots etc.
Once you get into the world of self prescribing or prescribing for others, you are in a dangerous world. I have seen this many, many times.
If you really want to carry top end analgesia, I would make sure you get a letter of authorisation. Otherwise, that opiate based med you have could get you put in jail.
It is great that you are thinking ahead. Google
"CAT torniqet"and "celox" these are two items that could come in handy also. You wont find these in most training schools.
