Generic drugs are clearly a way to save money.

Consumer Reports Medical Advisor Dr. Orly Avitzur says generics have the same active ingredient as the original and are required to be the same in almost every way -- same dose, same strength, same purity. Only the inactive ingredients, such as fillers can be different.

"Evidence is good that generics are safe and effective and a good choice for someone starting on a new medication."

And yet, some people say they switched to a generic and it didn't work as well. I asked Dr. Avitzur about that.

"Sometimes people don't like the way they taste or they may have unexpected reactions to those inactive ingredients, so after switching from any brand name medication to generic, if you have a problem, then certainly you should discuss it with your physician. But those kinds of incidents are quite rare."

While she recommends generics, Dr. Avitzur says you should never make a change on your own -- always check with your doctor first.
