Where should my doctor send my prescriptions for the home delivery pharmacy?

    • Once you’re registered, we will contact your doctor for a 90-day prescription with refills.
When should I order my refills for home delivery?
  • It’s time to order refills when you have a 10-14 day medication supply still on hand. Choose from three fast and easy options:
I am no longer taking this medication, how do I get off autofill?
  • Auto refill can be turned off on the Member Center or online ordering system. You may also call 866.516.1121 to discontinue auto refill via phone.
Where can I find receipts for my FSA or HSA card provider?
  • A full pharmacy receipt is included in your home delivery shipment, which can be used for reimbursement.
  • An Explanation of Benefits (EOB) can be printed using the Member Center. Simply login or create an account and choose Prescription History.
How do I update my payment information?
  • Payment information can be provided on the registration, refill or auto refill forms and can be authorized to remain on file.
  • You also have the option to add a new credit or debit card when ordering refills on the Member Center.
  • You may also provide your information over the phone with a representative.
Why am I receiving a bill when I’ve provided my credit card number?
  • For your credit card to be charged automatically, you must authorize it to remain on file with CastiaRx. If not authorized, you will need to provide it for each refill.
  • Your receipt may have been printed prior to your card being charged.
I was an NPS or LDI portal user and now I can’t log in. What should I do?
