As voted for in recent election the Oregon Prescription Drug Program is getting started. This is a program to create discounts for prescription medications for Oregonians. To learn more and sign up visit the official web site. Their site claims up to 60% discount with best discounts on generics.
Walmart also has a program that offers many commonly prescribed medications at $4. Wal-Mart official page lists medications included in the program. The majority of generic medications that have been on the market for a while.
Free Meds and Solutions is a clearinghouse for many discount prescription programs from drug companies. I know of at least one family that was able to get their medication through this site.
We have not directly evaluated any of these program and are not affiliated with them in any way. Hope you find them helpful for your family.
