How to Protect Yourself

  • Hang up immediately – If you receive an unexpected call and are unsure if it’s legitimate, do not engage. Hang up and contact CVS directly.
  • Verify with CVS – Call your local CVS pharmacy using their official number. Find a CVS near you: CVS Store Locator
  • Never share personal information – Do not provide your prescription details, insurance information, Social Security number, or financial details to unknown callers.
  • Contact your prescription drug provider – If you are unsure about a call related to your medication, reach out to your prescription provider directly:

Common Scam Tactics

Scammers may ask questions such as:

  • Do you need any medication refills?
  • What prescriptions are you taking?
