You can access a full range of safe and effective medicines. These medicines are part of a formulary, or Preferred Drug List (PDL).
Your doctor will use the PDL to choose the best medicine to treat you and your condition.

Occasionally, your provider may need to get our approval if he or she wants you to use a medicine that is not on our PDL. Your provider also will need to get approval if covered medicines have a limit such as:
- Age limit: covered for certain age group
- Quantity limits: a limit on the number of drugs you can get at once, per prescription (e.g., 30 tablets per 30 days). There is no limit on the total number of prescriptions you may have, though the state's limitation of two brand name prescriptions per month still applies. A third brand name prescription may be approved if it is found to be medically necessary.
- Step therapy: a preferred drug(s) must be tried first.
