How effective are antidepressants? That's a question that many people with depression have asked -- and research suggests that the answers aren't simple.
It's a question that's relevant to millions. About one in 10 Americans takes an antidepressant, now the most commonly prescribed type of drug in the U.S., according to research published in 2009 in the Archives of General Psychiatry. Much of the surge has happened in the past two decades. From 1996 to 2005, the rate of antidepressant use rose from 5.84% to 10.12%.
Back pain and muscle spasms. We've all experienced these symptoms from time to time. Lower back pain often comes from sitting at the computer too long. Many people have strained muscles along the spine from lifting a heavy object. But when the aches and spasms are vague -- and not related to any injury -- they may be symptoms of depression or other medical conditions. It's important to see a doctor for a medical evaluation to determine the cause.

But a report recently published in The Journal of the American Medical Association showed that the drugs work best for very severe cases of depression and have little or no benefit over placebo (inactive pills) in less serious cases.
That report isn't the last word on the topic, but it got plenty of media attention. So much, in fact, that many psychiatrists became concerned that people would misunderstand the findings and possibly dismiss crucial treatment.
But the controversy also creates an opening to get a reality check about the popular drugs' advantages and limitations, experts tell WebMD.
Here's what those experts said -- and the four questions they recommend you consider when deciding if an antidepressant is right for you.
The report published in JAMA isn't new research -- it's a pooled analysis of data from six previously published studies. And it only includes two types of antidepressants -- selective serotonin reuptake inhibitors (SSRIs) and older drugs called tricyclics.
In light of those limits, experts interviewed for this story caution against reading too much into the findings.
"This is the kind of study that really gets misinterpreted by the general public. It's always frustrating when that happens," says Jennifer Payne, MD, assistant professor of psychiatry at Johns Hopkins School of Medicine and director of the Women's Mood Disorders Center.
Some other psychiatrists agree. The report is "very limited," says David Mischoulon, MD, PhD, associate professor of psychiatry at Harvard Medical School and director of research at Massachusetts General Hospital's Depression and Clinical Research Program.
