What is a Generic Drug?

A generic drug is a copy of the brand-name drug with the same dosage, safety, strength, quality, consumption method, performance, and intended use. Before generics become available on the market, the generic company must prove it has the same active ingredients as the brand-name drug and works in the same way and in the same amount of time in the body.

The only differences between generics and their brand-name counterparts is that generics are less expensive and may look slightly different (eg. different shape or color), as trademarks laws prevent a generic from looking exactly like the brand-name drug.

Generics are less expensive because generic manufacturers don't have to invest large sums of money to develop a drug. When the brand-name patent expires, generic companies can manufacture a copy of the brand-name and sell it at a substantial discount.


Fosteum plus is a medical food that your doctor may prescribe for the treatment of osteopenia or osteoporosis. It is commonly prescribed for postmenopausal women who are experiencing age-related bone loss.

Over time, hormonal changes can cause the loss of bone mineral density, which is critical to maintaining bone strength. Normally, osteoclasts are bone cells that break down bone tissue while osteoblasts rebuild it. Fosteum plus works by stimulating osteoblasts and decreasing the activity of osteoblasts. Other ingredients in Fosteum Plus restore bone minerals to help rebuild.


Take Fosteum Plus exactly as directed by your doctor. It is normally taken one tablet by mouth every 12 hours. It can be taken with or without food.

If you miss a dose, take it as soon as you remember. Do not double up.
