Pushing Prozac

What are the risks?

WebMD Feature

June 2, 2000 -- For five years, antidepressant drugs have redefined daily life for Carla, a graphic designer in Des Moines, Iowa. They've helped her pry loose from depression so powerful she could barely get out of bed in the morning. They've helped her raise three teenage sons and put an end to her occasional thoughts of suicide.

But such help has come at a price -- a price some doctors are starting to question. Twelve years after Prozac first hit the market, a growing chorus of psychiatrists claims that America is becoming an overmedicated society, reaching for prescriptions at the first sign of mild depression -- and risking potentially dangerous side effects in the process.

Top 7 Therapy Myths Debunked

Many people have a perception of talk therapy that doesn't quite match up to reality. If you think therapy means lying on a couch with a box of tissues and paying top dollar to talk to someone who doesn't quite get it, or that it's only for people who are mentally ill, think again. It turns out that most people could benefit from therapy -- but it takes work on your part, a therapist who meets your needs and really does understand you, and as much time as it takes -- at your convenience and within...

Like Carla, one in eight Americans have taken one of the popular new class of antidepressants called selective serotonin reuptake inhibitors, according to an ABC News survey done in April. Better known by the brand names Prozac, Paxil, Zoloft, or Luvox, these drugs are thought to boost brain levels of the chemical serotonin and to quell an array of emotional disorders, from depression to panic to anxiety. Indeed, the drugs are so popular that an estimated 28 million Americans -- one in 10 -- currently use them. To date, over 60 million prescriptions for this class of drug have been written. That's a stunningly high figure considering that the National Mental Health Association estimates that only 19 million Americans suffer from severe depression.

Stephen Crystal, PhD, a Rutgers researcher who studies prescription trends, calls it a "massive uncontrolled experiment," in which doctors are handing their patients prescriptions when they haven't even been diagnosed with a mental disorder in the first place. Equally troubling, the ABC News survey found that nearly half of people on the new antidepressants have taken the drugs for a year or more, even though these drugs haven't been tested for long-term use.

Leading the dissent is Harvard psychiatrist Joseph Glenmullen, MD, author of Prozac Backlash. Glenmullen argues that as many as 75% of patients are on antidepressants for mild -- even trivial -- conditions. For many of these people, he says, the risk-benefit ratio of taking antidepressants is simply unacceptable.

For example, some studies have shown that Prozac and its cousins cause sexual dysfunction in up to 60% of users, though the drug's manufacturer, Eli Lilly and Co., says the rate is less than half that. Glenmullen points to a Spanish study published in the Journal of Sex and Marital Therapy in 1997 as one of the best examples: It examined the effects of Prozac, Paxil, Zoloft, and Luvox in 344 patients and found that 58% experienced sexual dysfunction. Weight gain and tremors are other leading side effects.

Carla is one patient who has struggled to find an antidepressant with few side effects. After her family doctor first prescribed Paxil five years ago, Carla found herself numb to everything around her. "I sure wasn't depressed anymore," she says. "I wasn't sad, I wasn't happy, I wasn't anything." Sex with her husband lost all its appeal. "It's kind of hard to have sex when you have no physical feelings and no emotional feelings."
