Anyone with a valid prescription can use Inside Rx. However, restrictions exist for certain featured brand medications only. For example, if you participate in a state or federally funded health care program, such as Medicare, Medicaid, TRICARE or others, you may not use Inside Rx to purchase specific featured brand medications, even if you elect to pay for the prescription as an uninsured or cash-paying patient. You may use Inside Rx if you are enrolled in one of these programs and choose to purchase generic or non-featured brand medications.
