CVS Caremark® Mail Service Pharmacy

For medications you fill regularly

For medications you fill regularly

Your plan offers a long-term supply at select retail pharmacies and mail order. A long-term supply is:


  • Up to a 90-day prescription if you have a prescription drug plan (PDP)
  • Up to a 100-day prescription if you have a Medicare Advantage prescription drug plan (MAPD)


Please refer to your plan benefit information for more details. This may be a great option if you take medications regularly.


You may find it more convenient to fill your prescription through preferred mail order.

Filling your prescriptions with a long-term supply means you’ll spend less time getting refills. And it may help you avoid running out of your medication.


Federal or state limitations may apply.
