It is going to depend upon your health conditions and what conditions the prescriptions are treating. We have been able to work with several different doctors since 2007 as well as our mail order pharmacy. We get blood work done when our doctors want it done and have the results sent back to them. It does require some planning. It also helped that our health care providers know that we are being responsible while we are on the road. We also carry our medical records and test results with us on usb drives in case of emergency which greatly helped when Dave had a heart attack while on the road in an unfamiliar area.
