Specialty pharmacy

Specialty drugs are prescriptions that require special delivery, handling, administration and monitoring by a pharmacist. These drugs are listed on the Providence Health Plan formulary with a status of "specialty."

  • Specialty drugs are available through Credena Health.
  • Some specialty drugs are denoted as Limited Access (LA) on the formulary. Credena Health may not be able to provide some of these medications since they are limited to only a few specialty pharmacies. For more information, consult your provider and pharmacy directory or call Customer Service at 877-216-3644 (TTY: 711), Monday-Friday, 8 a.m. - 6 p.m. (Pacific time).
