Following graduation from college several years ago I embarked on a backpacking trip in Europe and Russia. Prior to my departure I went to my doctor, informed her about my trekking plans and asked for some prescriptions for meds I might need while out of the US if I got sick. She had no problem giving me the scrips and advised me under which conditions to use which drugs.

If you feel you still need some meds, check with your doctor to see if he/she will provide a script.
