Generic drugs are priced much lower than the equivalent brand name versions - usually 30-75% less. Why? Generic drugs are less expensive because they do not require the same costly research, development, sales and marketing as brand name drugs. In fact, generic drugs are required to follow the same strict Food and Drug Administration (FDA) guidelines as brand name drugs. Many companies that manufacture brand name drugs also manufacture generic drugs.
Generic drugs have been used for various conditions for a long time with safe and effective results. Newer brand name drugs are more expensive, but they may not be any better. To find out whether a generic exists for your prescription, ask your doctor or pharmacist.
