Hello. Currently a resident of NY and prescribed Vyvanse through my psychiatrist in NY. I will be working in Los Angeles California for an extended period of time and my psychiatrist in NY said they are not licensed to prescribe my medication nor treat me in California.
Without having California insurance or residency what would be the easiest way to request a prescription via a video visit with a psychiatrist here? In other words, knowing I will have to pay out of pocket, what is the best verbiage to use in order to just request a prescription rather than new treatment?
Thanks!
