There is a new option for the millions of Americans affected by obesity. Qsymia is the first prescription weight loss drug to hit the market in more than a decade.

Qsymia is a combination of two medications that have long been used in weight management. One is an appetite suppressant. The other reduces cravings for food.

Prescription diet drugs have had a troubled past, but doctors say Qsymia is promising.

Patients lost an average of 10 percent of their body weight while on the medication.

But it isn't as easy as just popping a pill. The drug has to be used in conjunction with a healthy diet and exercise.
