This is clearly a scam. Do not give them any personal information!  The caller, a woman, said she was from Rx Pharmacy Services, calling about benefits for a topical pain relief gel, and she needed some information from me. "Are you still at ____ address?" (She named my correct address, as a way to draw me in and get me to say more.) I work in a medical profession and I immediately sensed something was up. I said, "Who is this gel for?" She answered, "HIPAA laws prevent me from answering that until I get more information."  At this point I said, "This call is clearly not legit. I am not giving you any information," and she hung up. I can see how people might get drawn in by this, especially if you assume the drug is for some other family member.

answered with the intent of teasing out info, recording replied "goodbye"  and disconnected.  added to blocked caller list
