Qsymia -- pronounced kyoo-SIM-ee-uh, according to Vivus Pharmaceuticals -- is the first new weight loss drug to reach market in 13 years. Vivus chose the name Qsymia after the FDA rejected a previous name, Qnexa.
The FDA approved Qsymia last July, a few weeks after granting approval to another weight loss pill, Belviq, which is expected to hit the market in early 2013. Qsymia and Belviq work in different ways.
It's an important day for people whose weight is destroying their health, says Sue Decotiis, MD, of New York's Manhattan Medical Weight Loss Physician, a practice specializing in obesity treatment. Decotiis has no ties to companies that make weight loss drugs.
"For us weight loss specialists, any new tool we can get our hands on is very exciting," Decotiis says. "We're not talking about the person who just needs to lose 10 pounds. We are talking about the patient who is obese or very overweight with related health problems."
Dramatic weight loss can come from lifestyle changes alone. Lifestyle change is hard for anyone, but obesity makes it harder. The body burns less and less fuel. Appetite increases. And exercise hurts.
"They get de-motivated quickly because they have no success," Decotiis says. "Doctors prescribe weight loss drugs knowing full well that any drug can have side effects or complications. But that is why it is put in the hands of a prescribing doctor, who will follow the patient carefully, monitoring for side effects and educating the patient."
Qsymia does have serious side effects. One of the most troublesome is that the drug can cause birth defects if taken during pregnancy. Women of childbearing age must confirm with their doctor that they are using 100% effectivebirth control before they can get a Qsymia prescription.
