The Alliance for Patient Access approaches the important subject or Non-Medical Switching. 
Patients with chronic or serious medical conditions must sometimes work with physicians for months to identify a medication that’s effective for them. But as a new video from the Alliance for Patient Access explains, patients may discover that this trial-and-error process was in vain. Through non-medical switching, insurers can compel patients to set aside their effective therapy for a less costly alternative—for reasons unrelated to patient health.
