Eight in 10 prescriptions are filled with generics rather than brand-name drugs these days.
The generics are usually inexpensive. Think $4 for a month's supply of the depression drug fluoxetine (or Prozac) at Wal-Mart. If you have insurance that covers pharmaceuticals, your copay will be lower with a generic than a brand-name drug, too.
Katie Alonzo was stunned when doctors told her they couldn't get a drug her 10-year-old daughter, Abby, was taking to fight lymphoma.
"When a doctor says, 'This is what you need to take.' And then all of a sudden somebody tells you, 'Well, that is what you need to take but this isn't available so we're going to try this instead,' it's very scary," say Alonzo, who lives in Port St. Lucie, Fla.
