What is the flow if a patient comes to a pharmacy with an RID and it appears that it is expired. Can the pharmacy then deliver? If not, what should he say to the patient?

The pharmaceutical product can not be OBTAINED FROM RECIP_E SO CERTAINLY NOT delivered. The patient needs to go back to his medical Doctor or you can phone him/ her to ask for a new prescription which you might also get access to digitally if there is a therapeutic relation (patient has e-ID with him/ her).
